Khaled Khelif, Rose Dieng-Kuntz
2004 Lecture Notes in Computer Science  
Finally, we argue that ontology-based semantic annotation can improve information retrieval. T 2 T Ontology GALEN., 2001  ...  Furthermore, we evaluate and discuss our method by applying it to the annotation of textual corpus provided by biologists working in the biochip domain.  ...  Since this phase of validation is based on information retrieval, our approach rests on the semi-automatic generation of semantic annotations for scientific articles in the DNA-microarray domain.  ...

Cross Lingual Semantic Search by Improving Semantic Similarity and Relatedness Measures [chapter]

Nitish Aggarwal
2012 Lecture Notes in Computer Science  
Although multilinguality of the web is a hurdle in information access, the rapid growth of the semantic web enables us to retrieve fine grained information across the language barrier.  ...  Secondly, we focus on improving the semantic similarity and relatedness measures, to overcome the semantic gap between the vocabulary in the knowledge base and the terms appearing in the query.  ...  With this approach, cross-lingual information retrieval at document level can also be performed, if the documents are already marked up with the structured knowledge base.  ...

2019 IEEE Access  
In addition, we evaluate various semantic QE approaches in terms of knowledge structure utilization, corpus collection, baseline model adaptation, and retrieval performance.  ...  These methods do not consider search query semantics, thereby resulting in ineffective retrieval of information.  ...  In contrast, semantic QE approaches do not have such limitations as they are based on corpus-independent knowledge structures (e.g., a lexical thesaurus or ontology).  ...

Hongyan Jing, Evelyne Tzoukermann
1999 Proceedings of the 22nd annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '99  
We present an approach to information retrieval based on context distance and morphology. Context distance is a measure we use to assess the closeness of word meanings.  ...  This context distance model measures semantic distances between words using the local contexts of words within a single document as well as the lexical co-occurrence information in the set of documents  ...  Sense-Based Retrieval The role of word sense disambiguation in information retrieval has been studied by several researchers.  ...
