SIGMOD acceptance rates have generally been in the narrow range of between 14 to 18 percent during the past decade. However, for given individuals the range is much wider. Some people have a zero percent acceptance rate, after five or six frustratingly ...

The efficient processing of large collections of patterns (Boolean expressions, XPath queries, or continuous SQL queries) over data streams plays a central role in major data intensive applications ranging from user-centric processing and ...

Analyzing and querying large volumes of spatially derived data from scientific experiments has posed major challenges in the past decade. For example, the systematic analysis of imaged pathology specimens result in rich spatially derived information ...

Proper physical design is a momentous issue for the performance of modern database systems and applications. Nowadays, a growing amount of applications require the execution of dynamic and exploratory workloads with unpredictable characteristics that ...

The trend to merge medical practices into cooperatively operating networks and organizational units like Medical Supply Centers generates new challenges for an adequate IT support. In particular, new use cases for common economic planning, controlling ...

This work investigates clustering techniques for Relation Extraction (RE). Relation Extraction is the task of extracting relationships among named entities (e.g., people, organizations and geo-political entities) from natural language text. We are ...

Recommender systems have become popular in both commercial and academic settings. The main purpose of recommender systems is to suggest to users useful and interesting items or content (data) from a considerably large set of items. Traditional ...

Regular expressions can be found in a wide array of technology for data processing on the web. We are motivated by two such technologies: schema languages for XML and query languages for graph-structured or linked data. Our focus is on theoretical ...

The goal of the semantic web is to make the information available on the web easier accessible. Its idea is to provide machine readable meta-data to enable the development of tools that support users in finding the relevant data.

The goal of the thesis ...

In real-world, entities change dynamically and the changes are capture in two dimensions: time and space. For data sets that contain temporal records, where each record is associated with a time stamp and describes some aspects of a real-world entity at ...

With the increasing application of Event Stream Processing (ESP) for event pattern detection, it has become important to enhance the extant ESP capabilities to deal with applications having dynamic behavior. This dissertation research explores the ...

As cloud computing environments become explosively popular, dealing with unpredictable changes, uncertainties, and disturbances in both systems and environments turns out to be one of the major challenges facing the concurrent computing industry. My ...

In recent years, we have seen an increasing number of applications in networking, sensor networks, cloud computing, and environmental monitoring, that aim to monitor, control, and make decisions over large volumes of dynamic data. In my dissertation, we ...
