RDF triplestores and property graph databases are two approaches for data management which based on modeling, storing, querying graph-like data. In spite of such common principles, they present special features that complicate the task database interoperability. While there exist some methods to transform graphs into graphs, vice versa, lack compatibility a solid formal foundation. This paper presents three direct mappings (schema-dependent schema-independent) transforming an database,...

Microbloging is an extremely prevalent broadcast medium amidst the Internet fraternity these days. People share their opinions and sentiments about variety of subjects like products, news, institutions, etc., every day on microbloging websites. Sentiment analysis plays a key role in prediction systems, opinion mining etc. Twitter, one platforms allows limit 140 characters to its users. This restriction stimulates users be very concise twitter ocean analyze. Twitter also provides developer...

The current decade is a witness to an enormous explosion of data being published on the Web as Linked Data maximise its reusability. Answering questions that users speak or write in natural language increasingly popular application scenario for Data, especially when domain not limited where dedicated curated datasets exist, like medicine. increasing use this and other settings has highlighted importance assessing quality. While quite some work been done with regard quality only few efforts...

In the past decade Knowledge graphs have become very popular and frequently rely on Resource Description Framework (RDF) or Property Graphs (PG) as their data models. However, query languages for these two models - SPARQL RDF PG traversal language Gremlin are lacking basic interoperability. this demonstration paper, we present Gremlinator, first translator from W3C standardized to a property graph language. Gremlinator translates queries path traversals executing pattern matching over...

It has long been thought that mRNA is labile and easily prone to degradation. However, a recent study demonstrated GAPDH in cell-free plasma may remain stable up 24 hours after blood collection. As there are no other independent studies, we attempted reproduce the findings of study. In our study, was collected from healthy male volunteer into Vacutainer tubes containing EDTA. Blood samples were placed on ice separated by double-centrifugation at times 0, 1, 2, 5 extracted four aliquots...

Whereas the availability of data has seen a manyfold increase in past years, its value can be only shown if variety is effectively tackled ---one prominent Big Data challenges. The lack interoperability limits potential collective use for novel applications. Achieving through full transformation and integration diverse structures remains an ideal that hard, not impossible, to achieve. Instead, methods simultaneously interpret different types available formats have been explored. On other...

Question Answering (QA) systems are becoming the inspiring model for future of search engines. While, recently, datasets underlying QA have been promoted from unstructured to structured with semantically highly enriched metadata, question answering still facing serious challenges and therefore not meeting users' expectations. This paper provides an exhaustive insight known so far building systems, a special focus on employing data (i.e. knowledge graphs).It thus helps researchers easily spot...

Knowledge graphs, usually modelled via RDF or property have gained importance over the past decade. In order to decide which Data Management Solution (DMS) performs best for specific query loads a knowledge graph, it is required perform benchmarks. Benchmarking an extremely tedious task demanding repetitive manual effort, therefore advantageous automate whole process. However, there currently no benchmarking framework supports and comparing diverse DMSs both graph DMS. To this end, we...

This article presents sparql-gremlin, a tool to translate SPARQL queries Gremlin pattern matching traversals. Currently, sparql-gremlin is plugin of the Apache TinkerPop graph computing framework, thus users can run expressed in W3C query language over wide variety data management systems, including both OLTP databases and OLAP processing frameworks. With we perform first step bridge interoperability gap between Semantic Web Graph database communities. The has received adoption from academia...

RDF and Property Graphs are data models that being used to represent Knowledge Graphs. The definition of methods transform into graph is fundamental allow interoperability among the systems using these models. Although both based on a structure, they have special features complicate transformation methods. This article presents an ontology-based approach (automatically) property graphs graphs. ontology, called PGO, defines set terms allows describing elements graph. algorithm corresponding...

Following the Linked Data principles means maximising reusability of data over Web. Reuse datasets can become apparent when are linked to from other datasets, and referred in scientific articles or community discussions. It thus be measured, similarly citations papers. In this paper we propose dataset reuse metrics use these analyse indications different communication channels within a community. particular consider mailing lists publications Semantic Web their correlation with interlinking....

In this paper, we survey various user-centered or context-based biomedical health information retrieval systems. We present and discuss the performance of systems submitted in CLEF eHealth 2014 Task 3 for purpose. classify focus on comparing two most prevalent models namely: Language Model (LM) Vector Space (VSM). also report effectiveness using external medical resources ontologies like MeSH, Metamap, UMLS, etc. observed that L.M. based outperform VSM fronts. From results conclude...

Knowledge graphs have become popular over the past years and frequently rely on Resource Description Framework (RDF) or Property Graphs (PG) as underlying data models. However, query languages for these two models -- SPARQL RDF Gremlin property graph traversal are lacking interoperability. We present Gremlinator, a novel to translator. Gremlinator translates queries traversals executing pattern matching databases. This allows access wide variety of Graph Data Management Systems (DMS) using...
