چکیده

We describe in this paper a boolean Information l~.etrieval system that adds word semantics to the classic word based indexing. Two of the main tasks of our system, namely the indexing and retrieval components, are using a combined wordbased and sense-based approach. The key to our system is a methodology for building semantic representations of open text, at word and collocation level. This new technique, called semantic indexing, shows improved effectiveness over the classic word based indexing techniques. 1 I n t r o d u c t i o n The main problem with the traditional boolean word-based approach to Information Retrieval (IR) is that it usually returns too many results or wrong results to be useful.

A concept-based approach for indexing documents in IR

This paper addresses two important problems related to the use of semantics in IR. The first one concerns the representation of document semantics and its proper use in retrieval. The second is the integration of semantic-based retrieval with "traditional" keywords-based retrieval. The proposed approach aims to represent the document content by the best semantic network called document semantic...

Semantic Hand-Tagging of the SenSem Corpus Using Spanish WordNet Senses

This paper presents the semantic annotation of the SenSem Spanish corpus, a research focused on the semantic annotation of the nominal heads of the verbal arguments, with the final goal of acquiring semantic preferences for verb senses. We used Spanish WordNet 1.6 senses in the annotation process. This process involves the analysis of the adequacy of WordNet for semantic annotation and, in case...

The HCONE Approach to Ontology Merging

Existing efforts on ontology mapping, alignment and merging vary from methodological and theoretical frameworks, to methods and tools that support the semi-automatic coordination of ontologies. However, only latest research efforts “touch” on the mapping /merging of ontologies using the whole breadth of available knowledge. This paper aims to thoroughly describe the HCONE approach on ontology m...

The Role of Semantic Roles in Disambiguating Verb Senses

We describe an automatic Word Sense Disambiguation (WSD) system that disambiguates verb senses using syntactic and semantic features that encode information about predicate arguments and semantic classes. Our system performs at the best published accuracy on the English verbs of Senseval-2. We also experiment with using the gold-standard predicateargument labels from PropBank for disambiguating...
