- 140 abstract "Cross-Language Information Retrieval (CLIR) systems extend classic information retrieval mechanisms for allowing users to query across languages, i.e., to retrieve documents written in languages different from the language used for query formulation. In this paper, we present a CLIR system exploiting multilingual ontologies for enriching documents representation with multilingual semantic information during the indexing phase and for mapping query fragments to concepts during the retrieval phase. This system has been applied on a domain-specific document collection and the contribution of the ontologies to the CLIR system has been evaluated in conjunction with the use of both Microsoft Bing and Google Translate translation services. Results demonstrate that the use of domain-specific resources leads to a significant improvement of CLIR system performance.".

- 144 sameAs 144.
- 144 abstract "In many applications (like social or sensor networks) the information generated can be represented as a continuous stream of RDF items, where each item describes an application event (social network post, sensor measurement, etc). In this paper we focus on compressing RDF streams. In particular, we propose an approach for lossless RDF stream compression, named RDSZ (RDF Differential Stream compressor based on Zlib). This approach takes advantage of the structural similarities among items in a stream by combining a differential item encoding mechanism with the general purpose stream compressor Zlib. Empirical evaluation using several RDF stream datasets shows that this combination produces gains in compression ratios with respect to using Zlib alone.".

- 145 label "Towards Competency Question-driven Ontology Authoring".
- 145 sameAs 145.
- 145 abstract "Ontology authoring is a non-trivial task for novice authors who are not proficient in logics. It is difficult to either specify the requirements to an ontology, or test the satisfaction of them. In this paper, we propose a novel approach to addressing this problem by leveraging the ideas of competency questions and test-driven software development. We first analyse real-world competency questions collected from two different domains. Analysis shows that many of them can be categorised into several frequent patterns that differ along a set of features. Then we employ the notion of presupposition from linguistics to describe the ontology requirements implied by competency questions, and show that these presuppositions can be tested automatically.".
