Using Semantic and Domain-Based Information in CLIR Systems [chapter]

Alessio Bosca, Matteo Casu, Mauro Dragoni, Chiara Di Francescomarino
2014 Lecture Notes in Computer Science  
Results demonstrate that the use of domain-specific resources leads to a significant improvement of CLIR system performance.  ...  This system has been applied on a domainspecific 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  ...  In this case, only queries containing at least one term matching the Domain Ontology have been performed.  ...

Research on Ontology-Driven Information Retrieval [chapter]

Stein L. Tomassen
2006 Lecture Notes in Computer Science  
The ontology concepts are adapted to the domain terminology by computing a feature vector for each concept. Later, the feature vectors are used to enrich a provided query.  ...  We describe how these systems can be enriched with adapted ontologies to provide both an in-depth understanding of the user's needs as well as an easy integration with standard vector-space retrieval systems  ...  This research work is funded by the Integrated Information Platform for reservoir and subsea production systems (IIP) project, which is supported by the Norwegian Research Council (NFR).  ...
