The client terminal 5 displays a search result display screen 22 on which a regular search result and a separate aspect search result are simultaneously displayed.

Description

Search system, search program, and client program

The present invention relates to a search system used to search for information on the Internet.

Search systems are used by users to search for desired information from a large amount of information on the Internet. In a search system, a search word (search query) input into a search window of a browser of a client terminal is transmitted to a server device, and a search using the search word is performed by a search engine operating in the server device. The results of the search by the search engine are then transmitted from the server device to the client terminal and displayed on the client terminal's browser (for example, Patent Document 1).

Patent No. 6790942

By the way, conventional search systems such as Google (registered trademark) can only reach web pages and information that are highly relevant to the search word. Therefore, it is difficult to gain new awareness. This is not a problem for users who are looking up the meaning of words, but it is useful when it is useful to gain new knowledge (for example, when conducting research for product development or marketing purposes). It's hard to call it a thing.

The present invention has been made in view of the above circumstances, and an object of the present invention is to realize a search system that allows a user of a client terminal to find unexpected information.

In order to solve the above-mentioned problems, a first invention displays a search word input screen on a client terminal, and the search words input on the input screen are delivered to a server device connected to the client terminal via the Internet. A search engine running on a server device performs a search, and when the results of the search by the search engine arrive at a client terminal, the search system displays a search result display screen on the client terminal to display the search results. Therefore, search engines perform two types of searches: normal search, which searches for related information related to a search word, and alternative search, which searches for other side information related to another word that is derived from the search word and has a different meaning from the search word. The search system is configured to perform at least one search, and the results of the normal search and the results of the other aspect search are simultaneously displayed on the search result display screen.

A second invention is that in the first invention, identification information is displayed on the search result display screen for the user of the client terminal to identify the results of the normal search and the results of the other aspect search.

A third invention is a serendipity method in which a user of a client terminal searches for serendipity information that a user of a client terminal feels is coincidental, using a chance search word obtained by elemental decomposition of a search word as another word in the first invention. It's a search.

In a fourth invention, in the third invention, the serendipity search is used as the first alternative search, and the search engine uses an opposite search word having the opposite meaning to the search word as the second alternative search. A reverse search is further performed to search for reverse information using another word, and the results of the normal search, the serendipity search, and the reverse search are displayed simultaneously on the search result display screen.

A fifth invention is based on the third invention, wherein the serendipity search is used as the first alternative search, and the search engine uses the search word as the second alternative search to search a plurality of types of databases using objective information. The search is further performed, and the results of the normal search, the results of the serendipity search, and the results of the objective information search are displayed simultaneously on the search result display screen.

A sixth aspect of the present invention is based on the first aspect, when a screen scrolling operation is performed on the search result display screen, the results of the normal search and the results of the other aspect search are scrolled at the same time.

A seventh invention is based on the first invention, in which, on the search result display screen, narrowing down to one type of search results from multiple types of search results including normal search results and other aspect search results is performed. A selection operation is possible, and when the selection operation is performed, a narrowing viewing screen that displays only one type of search result selected by the selection operation out of multiple types of search results is displayed on the client terminal. .

An eighth invention is a search program that implements a search engine in a server device connected to a client terminal via the Internet, and when a search word is received from the client terminal to the computer of the server device, the search engine is activated. As an operation, a step of performing at least a normal search for searching for related information related to the search word and a different aspect search for searching for other aspect information related to another word derived from the search word and having a different meaning from the search word. This is a search program that causes a client terminal to which a search word is transmitted to execute the steps of transmitting information including the results of a normal search and the results of a different aspect search.

A ninth invention is a client program for realizing browsing of search results by a search engine in a client terminal connected via the Internet to a server device on which a search engine operates, the program comprising: A step of transmitting the search word entered on the input screen displayed on the client terminal to the server device, a normal search for searching for related information related to the search word, and a step of searching for related information related to the search word, and a step of searching for a meaning derived from the search word and different from the search word. When information including the results of the normal search and the results of the other aspect search is delivered to the client terminal from a server device running a search engine that performs at least another aspect search that searches for other aspect information related to another word having . This is a program for a client that executes the step of transitioning the screen display of a client terminal to a search result display screen that displays the results of a normal search and the results of a different aspect search at the same time.

In the present invention, the search engine not only searches for related information related to a search word, but also searches for information on other aspects using another word that is derived from the search word and has a different meaning from the search word. A lateral search is performed. Then, on the search result display screen displayed on the client terminal, the results of the normal search and the results of the other aspect search are displayed simultaneously. This allows the user of the client terminal to view not only the results of the normal search but also the results of the other aspect search, allowing the user to arrive at information that the user had not expected.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following embodiments are examples of the present invention, and are not intended to limit the scope of the present invention, its applications, or its uses.

[Search system overview]
The search system 10 is a web search system used to search for information (resources) such as web pages, documents (papers, articles, etc.), images, videos, etc. on the Internet 6. The search system 10 includes a server device 11 connected to a client terminal 5 via the Internet 6 (see FIG. 1).

The server device 11 is installed with a search program that implements a search engine. In the server device 11, a search engine operates as a CPU (processor) executes and interprets a search program, and a database creation section 11a and a search section 11b are realized as functional blocks. In the database creation unit 11a, a crawler patrols the Internet 6 and collects resource information, and an indexer creates an index (database) 11c from the resource information. When the search unit 11b receives a search word (search query) from the client terminal 5, it searches the index 11c and outputs the search result to the client terminal 5 to which the search word is transmitted. This search result (transmission information) includes list information such as web pages (resource list information) for each of the three types of search results described below.

The client terminal 5 has installed therein a client program that allows input of search words, viewing of search results by a search engine, and the like. In the client terminal 5, a CPU (processor) executes and interprets a client program, thereby realizing a search word processing section 5a and a viewing processing section 5b as functional blocks. The search word processing unit 5a displays a search word input screen 21 (see FIG. 2) on the client terminal 5, and upon receiving an operation to execute a search by the user of the client terminal 5, inputs the search word into the search window 21a of the input screen 21. The search word is sent to the server device 11. When the viewing processing unit 5b receives the above-mentioned transmission information from the server device 11, it displays a search result display screen 22 (see FIG. 5) on the screen of the client terminal 5 for displaying the search results. Note that the client program may operate on the client terminal 5 or may operate on the cloud.

[About search engine]
In this embodiment, the processing of the search unit 11b (processing of the search engine) allows searching for things from multiple angles. The search unit 11b is configured to perform three types of searches when a search word is received from the client terminal 5. The search unit 11b provides bias-free search results in any of the three types of searches. The three types of searches are normal search, serendipity search (first alternative search), and opposite search (second alternative search).

FIG. 3 is an example of the processing flow of the search unit 11b. When the search unit 11b receives a search word from the client terminal 5, it starts a processing flow and performs a normal search process P1, a serendipity search process P2, and a reverse search process P3 in parallel.

The normal search is to search for related information (related resources) related to the search word from the information stored in the index 11c. In the normal search process P1, an index search S11 is performed in which the search word is used as it is as the search word in the index 11c.

Serendipity search uses chance search words (another word) obtained based on related words related to the search word to search for serendipity information (another aspect resource ). In the serendipity search process P2, an accidental search word acquisition S21 that acquires an accidental search word from a search word, and an index search S22 that uses the accidental search word as a search word in the index 11c are performed in this order.

Regarding the method for acquiring words for accidental search, in step S21, the search unit 11b acquires related words (primary related words) of the search word, and then uses secondary related words related to the primary related words as words for accidental search. Perform the processing to obtain as . For example, if the search word is "war," the primary related word candidates include "dispute," "politics," "history," "lifestyle," and "history/journalism." When "history/journalism" is acquired as a primary related word, the secondary related word "photo" related to "history/journalism" is coincidentally acquired as a search word. Further, when "dispute" is acquired as a primary related word, a secondary related word "family court" related to "dispute" is coincidentally acquired as a search word. Note that in the chance search word acquisition S21, the chance search word may be acquired through another process, such as directly acquiring a word related to the search word as the chance search word.

Regarding the method for acquiring related words in step S21, for example, the language dictionary database 15 is provided in the server device 11 in advance, and the search unit 11b acquires primary related words by searching the meaning of the search word in the language dictionary database 15. do. Then, the search unit 11b acquires secondary related words by searching the language dictionary database 15 for the meaning of the primary related words. The language dictionary database 15 includes the meanings of many words, the origin of words, classification of words, relationships between words (superordinate and subordinate relationships, synonymous relationships, similar meaning relationships, antonymous relationships, etc.), etc. It is a database that records information, and is made up of, for example, data from a thesaurus dictionary. Further, when a plurality of candidates for related words (secondary related words) are found by searching for meanings in the language dictionary database 15, one candidate can be randomly selected as the related word using random numbers or the like. However, if a plurality of related word candidates exist, one candidate may be selected as the related word using a predetermined algorithm.

In addition, in the language dictionary database 15, in association with the search target word (search word, primary related word) whose meaning is searched in the language dictionary database 15, the search target word is abstracted, conceptualized, concretized, and decomposed into elements. Words obtained by such methods are recorded as related words. For example, if the search target word is "apple," related words include "fruit" and "nutrition." When the search target word is "fruit," "fertilizer" is one of the related words. When the search target word is "nutrition," "vitamin" is one of the related words. When the search target word is "war", "part of history" is one of the related words. When the search target word is "part of history," "photo" is one of the related words. Note that these are just examples of related words.

The opposite search is to search for opposite information (another aspect resource) from the information stored in the index 11c using an opposite search word (another word) that has the opposite (opposite) meaning to the search word. In the reverse search process P3, a reverse search word acquisition S31 in which a reverse search word is acquired from a search word, and an index search S32 using the reverse search word as a search word in the index 11c are performed in this order. Regarding the method for acquiring the opposite search word, the search unit 11b searches the language dictionary database 15 described above in step S31, and performs processing to acquire the opposite search word corresponding to the search word. However, the method for acquiring the opposite search word is not limited to this process. Note that if there is no opposite search word to the search word, no opposite search is performed.

[About client terminal]
The screen display of the client terminal 5 changes depending on the processing of a program dedicated to the client or a program running on a web browser. Specifically, the screen display of the client terminal 5 starts from the input screen 21 shown in FIG. Then, when the user of the client terminal 5 inputs a search word and performs an operation to execute the search, transmission information including the results of the search by the search engine is received from the server device 11. Then, the viewing processing unit 5b performs processing according to the flowchart shown in FIG.

When the browsing processing unit 5b receives the search results from the search engine, it displays S41 on the search result display screen 22 shown in FIG. Further, when a predetermined operation (a selection operation described later) is performed on the search result display screen 22, the viewing processing unit 5b displays the narrowing viewing screen 23 shown in FIG. When another predetermined operation is performed in step 22, the positioning map 24 shown in FIG. 10 is displayed S43. Also on the narrow-down viewing screen 23, when a predetermined operation (map transfer operation described later) is performed, the positioning map 24 shown in FIG. 10 is displayed S43. In addition, when the user clicks on a link to a web page on the search result display screen 22, narrowed viewing screen 23, or positioning map 24, the viewing processing unit 5b transitions to the web page.

On the search result display screen 22, search results from the three types of searches described above (normal search results, serendipity search results, and reverse search results) are displayed simultaneously. Each type of search result is composed of information (list information) of a large number of web pages, etc. (resources). Among the three types of search results, at least for each of the normal search result and the opposite search result, the above-mentioned list information includes ranking information based on the search.

As shown in FIG. 5, information on each web page (resource) is displayed inside

display frames

25n, 25s, and 25r having a predetermined shape (such as a circle). Here, the code 25n represents a display frame for web pages etc. included in the results of a normal search, the code 25s represents a display frame for web pages etc. included in the results of a serendipity search, and the code 25r represents a display frame for web pages etc. included in the results of a serendipity search. Represents a display frame for WEB pages, etc. included in the results. Furthermore, identification information 26 indicating which of the three types of search results is the search result is added to each of the display frames 25n, 25s, and 25r. In this embodiment, the results of the normal search are given the identification information 26 that is displayed as "Tru", the results of the serendipity search are given the identification information 26 that is shown as "Even", and the results of the serendipity search are given the identification information 26 that is shown as "Even". The result is attached with identification information 26 indicating "No". Inside the display frames 25n, 25s, and 25r, for example, title information such as a web page and a portion of publication information such as a web page are displayed. The display frames 25n, 25s, and 25r have link information (for example, URL (Uniform Resource Locator)) to a web page or the like. A user can access a web page or the like by clicking within the display frames 25n, 25s, and 25r.

Next, screen scrolling on the search result display screen 22 will be explained. On the search result display screen 22, three types of search results can be scrolled simultaneously. Here, in the virtual area shown in FIG. 6, display frames (virtual display frames) 25n, 25s, and 25r for web pages, etc. that constitute the three types of search results transmitted from the server device 11 are arranged in three directions from the center S. They are arranged on lines L1, L2, and L3 that extend to . When the search result display screen 22 is displayed, the area R on the center S side in FIG. 6 is displayed on the screen of the client terminal 5. The three lines L1, L2, and L3 are provided for the purpose of displaying screen design. Three types of search results are arranged in each line L1, L2, and L3. In other words, each line L1, L2, L3 is not associated with one type of search result. Note that the number of these lines may be other than three, or there is no need to provide any lines.

In the virtual area shown in FIG. 6, the results of the normal search (virtual display frame 25n) and the results of the opposite search (virtual display frame 25r) are displayed according to the search in the scroll direction based on the above-mentioned list information. They are arranged in order according to the ranking. For each of the normal search results and the reverse search results, virtual display frames 25n and 25r of higher ranking are arranged closer to the center S. As a result of the serendipity search, multiple web pages, etc. (virtual display frame 25s) included in the above list information are arranged in a random order using random numbers etc. in the scroll direction, regardless of the ranking by the search. be done. In addition, since the results of the opposite search and the results of the serendipity search do not correspond to the content that the user is trying to search, the virtual display frame 25r of the opposite search is It is preferable that both the ratio of the serendipity search virtual display frame 25s and the ratio of the virtual display frame 25s for the serendipity search be small, and the respective ratios can be arranged so as to be, for example, 20% or less. In this embodiment, as shown by arrow A in FIG. 5, the screen of the client terminal 5 scrolls toward the front or back of the screen (in the vertical direction of the screen). In FIGS. 6 to 8, the ranking of the search is written in parentheses in the display frames 25n and 25r for the results of the normal search and the reverse search.

For example, when an operation is performed to move forward in the scrolling direction (direction of arrow A1 in FIG. 6) gradually increases in size while moving away from the center S, and finally moves to the outside of the screen. will newly appear from the center S side of the screen. Then, the newly appearing display frame 25 gradually becomes larger while moving away from the center S, similarly to the already appeared display frame 25. On the other hand, when an operation is performed to return the scroll in the backward direction (direction of arrow A2 in FIG. 8), the appeared display frame 25 gradually becomes smaller as it approaches the center S side in each line L1, L2, and L3. On the other hand, in FIG. 6, the display frame 25 that is one space inside the already-appeared display frame 25 newly appears from outside the screen. In this embodiment, the display frame 25 displayed on the screen of the client terminal 5 is switched by scrolling so that the user moves through a tunnel in which three types of search results are arranged in order. The user can simultaneously view three types of search results in a bird's-eye view. In addition, in this scrolling, the display frame 25 with the lowest search ranking is placed behind and adjacent to the display frame 25 with the first search ranking for the normal search results and the opposite search results, so the first place By scrolling backward from the display frame 25, the lowest display frame 25 is displayed.

Furthermore, by operating the search result display screen 22, the user can narrow down the search results to one of the three types and view them. When this screen operation is performed, the screen changes to a screen 23 for narrowing down viewing shown in FIG. Specifically, this screen operation is an operation of dragging and dropping the display frames 25n, 25s, and 25r displayed on the search result display screen 22 from above the lines L1, L2, and L3 to outside the lines. At this time, if the display frame to be dragged and dropped is the normal search display frame 25n, the screen will transition to the filtered viewing screen 23 where only the results of the normal search are displayed, and if the display frame is the serendipity search display frame 25s. , the screen transitions to the screen for narrowing down viewing 23 where only the results of the serendipity search are displayed, and if it is the display frame 25r of the opposite search, the screen transitions to the screen for narrowing down viewing 23 where only the results of the opposite search are displayed.

On the filtered viewing screen 23, only the search results of one type of search selected by the user from among the three types of search results (hereinafter referred to as "refined search results") are displayed. On the filtered viewing screen 23, information on a large number of web pages and the like (resources) forming the filtered search results is displayed in a horizontal scrolling manner. In the narrowed viewing screen 23, part or all of the information published on each web page etc. is displayed inside the display frame 28. Part of the posted information such as the web page is displayed when, for example, the amount of posted information such as the web page exceeds the amount that can be displayed in the display frame 28. Further, like the display frame 25, the display frame 28 also has link information to a web page or the like. By clicking within the display frame 28, the user can access a web page or the like. In addition, in the above-mentioned horizontal scrolling, since the display frame 28 with the lowest search ranking is placed behind and adjacent to the display frame 28 with the first search ranking, scrolling in the backward direction from the display frame 28 with the first place Then, the lowest display frame 28 is displayed.

Here, when comparing the display frame 28 of the filtered viewing screen 23 and the display frame 25 of the search result display screen 22, the display frame 28 has a larger area and a larger amount of displayed information. Therefore, compared to the search result display screen 22, the user can select a web page that he/she wishes to access while grasping the contents of each web page in more detail.

In this embodiment, when the user performs a map migration operation, a positioning map 24 (see FIG. 10) that visualizes the nature of information about the web page, etc. (resource) being viewed is generated, and the positioning map 24 (see FIG. 10) is generated. displayed on the screen. The map transition operation is an operation of clicking on an area outside the display frame 28 on the screen or a blank area of the display frame 28.

Here, the positioning map 24 arranges web pages, etc. (resources) in a predetermined order (search order etc.) or randomly arranged. The positioning map 24 is provided with reference lines 29 for web page arrangement extending radially from the center, and each reference line 29 is assigned one of a plurality of information categories C.

The published content of multiple web pages included in the three types of search results is determined by analyzing meta information (web page owner, article theme and text, article author, etc.) to determine which of multiple information categories C. It is determined whether it is compatible. Based on the determination result, the icon 30 representing each web page etc. is placed on the reference line 29 of the corresponding information category C. Note that the icon 30A representing the web page or the like that was being viewed at the time of the map transfer operation is displayed so as to be distinguishable from the other icons 30. In this embodiment, only the icon 30A is colored. Note that the positioning map 24 may be one in which web pages and the like are arranged separately for each information category C. For example, the positioning map 24 is divided into a plurality of parts in the vertical direction, and the information categories to be arranged are arranged in each divided area. C may be assigned. A part of the positioning map 24 is displayed on the screen of the client terminal 5, and the screen display area (information category C) is switched by a horizontal scroll.

Furthermore, when the user performs an operation to select a specific web page (icon) 30 or information category C on the positioning map 24 (by clicking on the display part), the screen transitions to the search result display screen 22 (see FIG. 4). However, on the search result display screen 22 displayed by this transition, the WEB pages etc. 30 narrowed down to the information category C selected by the user (if the WEB page 30 is selected, the information category C corresponding to the WEB page 30) Only the display frame 25 is displayed.

[Effects of embodiments, etc.]
In this embodiment, the search engine not only performs a normal search to search for related information related to a search word, but also searches for other side information using another word derived from the search word and having a different meaning from the search word. Two types of searches are performed as different aspect searches. Then, on the search result display screen 22 displayed on the client terminal 5, the results of the normal search and the results of two types of different aspect searches are displayed simultaneously. As a result, the user of the client terminal can view not only the results of the normal search but also the results of the two types of different aspect searches, so that the user can arrive at information that the user had not expected.

[First modification of embodiment]
In the above embodiment, the search unit 11b performs a normal search, a serendipity search, and a reverse search, but it may also perform a normal search, a serendipity search, and a reflection search (objective information search). In other words, a reflection search may be performed instead of a reverse search.

Reflection search is a search that encourages the user to think introspectively and thoughtfully about information, and provides the user with highly objective information regarding the search word. A plurality of types of databases 31 to 34 containing highly objective information are used for the reflection search. The multiple types of databases 31 to 34 include an encyclopedia/dictionary database 31 in which meanings are associated with individual words, a dissertation database 32 in which a large number of papers are collected, a book database 33 in which a large number of books are collected, A newspaper article database 34 in which a large number of newspaper articles are collected can be used (see FIG. 11). These databases 31 to 34 may be prepared by a business that provides a search service using the search system 10, or may be a database that is generally available or a database that is available only to contractors.

FIG. 12 is an example of the processing flow of the search unit 11b. When the search unit 11b receives a search word from the client terminal 5, it starts a processing flow and performs a normal search process P1, a serendipity search process P2, and a reflection search process P4 in parallel.

In the reflection search process P4, a search S41 of each database 31 to 34 is performed using the search word. A collection of search results obtained from the plurality of databases 31 to 34 becomes the result of the reflection search. Then, on the search result display screen 22, the results of the normal search, the results of the serendipity search, and the results of the reflection search are displayed simultaneously. In FIGS. 5-8, the reference numeral 25r corresponds to the result of the reflection search.

Note that the search unit 11b is configured to perform three types of searches: normal search, serendipity search, and reverse search, and may perform reflection search when no results are obtained from reverse search.

[Other embodiments]
In the embodiment described above, two types of alternative searches (serendipity search and reverse search) are performed, but either one of the searches may be performed together with the normal search.

In the above-described embodiment, the search result display screen 22 divides the screen area into three in the horizontal or vertical direction to provide three divided areas, and displays three types of search results separately in the three divided areas. There may be. In this case, the three types of search results may be scrollable simultaneously or individually.

In the embodiment described above, the results of the serendipity search may also be arranged in the virtual area shown in FIG. 6 in the order according to the ranking according to the search in the scroll direction based on the list information described above.

The present invention is applicable to search systems used to search for information on the Internet.
