HDT is a popular compressed file format to store, share and query large RDF Knowledge Graphs (KGs). While all these operations are possible in low hardware settings (i.e. a standard laptop), the generation and updates of HDT files come with an ...

In the rapidly evolving domain of Industry 4.0, effective management of software updates is crucial for maintaining system continuity and security. This paper presents a novel machine learning-based approach for a prompt and effective triage of ...

Weak ontic necessity is the ontic necessity expressed by “should/ought to” in English. An example of it is “I should be dead by now”. A feature of this necessity is that whether it holds at the present world is irrelevant to whether its prejacent ...

We propose an approach to assess, and thus, update the technology roadmapping process. Building on extant literature, we define the ideal roadmapping process and suggest an integrated framework to guide its improvement from three ...

Reconfigurable Hybrid (electrical/optical) Network (RHN) [1-4, 6, 8, 10, 11, 13-19] for modern datacenter architectures has gained significant momentum during the last decade. The primary advantage of such RHN architectures is the dynamic topological ...

This paper introduces SetUp, a theoretical and applied framework for the management of RDF/S database evolution on the basis of graph rewriting rules. Rewriting rules formalize instance or schema changes, ensuring graph's consistency with respect to ...

Background: The number of Systematic Literature Reviews published in Software Engineering has been increasing in recent years. Due to this fact, one point not addressed is the possibility of plagiarism when dealing with SLRs, especially when dealing ...

Software updates for blockchain systems become a real challenge when they impact the underlying consensus mechanism. The activation of such changes might jeopardize the integrity of the blockchain by resulting in chain splits. Moreover, the ...

Supporting frequent update throughput is an essential issue in applications that involve monitoring and querying continuous variables. We present an I/O optimal method to efficiently update the disk-resident interval tree for a set of new ...

Given a square matrix $M={(u_{\mathit{ij}})}_{n\times n}$ and an m-order matrix polynomial $f_m(M)={\sum }_{k=0}^m{a}_k{M}^k=a_{0}I+a_{1}M+a_2{M}^2+\cdots +a_m{M}^m$, if M is a dense matrix and is perturbed to become $M^{\prime }$ at a single entry, say $u_{\mathit{pq}}$, a straightforward re-calculation of $f_m(M^{\prime })$ would require $O(n^{\omega }·\alpha (...$$\mathrm{}$$$${}^{}\mathrm{}$${}_{}{}^{}$${}_{}$${}^{\mathrm{}}$${}^{\mathrm{}}$

We study multi-attribute trajectories by combining standard trajectories (i.e., a sequence of timestamped locations) and descriptive attributes. A new form of continuous k nearest neighbor queries is proposed by integrating attributes into the ...

In the medium access control layer (MAC) of WSN, the scheduling mechanism of nodes based on the periodical listen/sleep is an effective way of saving node energy consumption. In the case of data transmission which is not affected reduces the nodes' ...

Within the Semantic Web community, SPARQL is one of the predominant languages to query and update RDF knowledge. However, the complexity of SPARQL, the underlying graph structure and various encodings are common sources of confusion for Semantic ...

Internet of Things (IoT) require ubiquitous and seamless network connectivity. Meanwhile, it also asks for effective service management, data transmission and analysis. Towards this end, software defined networks (SDN) technology is introduced as a key ...

Distributed storage systems usually adopt erasure coding to achieve better tradeoff between the space efficiency and the data reliability. In-place updates are often used to overwrite the existing data rather than append the new data so as to ensure the ...

The global skyline, as an important variant of the skyline, has been widely applied in multi-criteria decision making, business planning and data mining. In this paper, we extend our early work and propose the maintenance methods to process the subspace ...

HighlightsWe formalize the problem of MDS as the weighted hierarchical archetypal analysis problem.The weighted hierarchical archetypal analysis shows the ability to select "the best of the best" summary sentences.The paper demonstrates how four ...

In OpenFlow-driven SDN, flow tables are TCAM-hungry; commodity switches suffer from limited concrete flow table size. One method for coping with the limitations is to use aggregation schemes to reduce the number of flow entries required to express the ...

Throughout the last decade, two distinct knowledge representation paradigms have been standardised to capture rich metadata on the Web: ontology languages based on Classical Logic and reasoning rules based on Logic Programming. Both offer important ...

Due to the recent development of digital TV broadcasting systems, contents data broadcasting using voices or movies has attracted great attention. In general broadcasting systems, the server broadcasts the same data repetitively and clients wait until ...
