On the Query Refinement in the Ontology-Based Searching for Information [chapter]

Nenad Stojanovic
2003 Lecture Notes in Computer Science  
For each of these ambiguities we defined the set of refinements/explanations, which help in more efficient searching for information in an ontology-based information repository.  ...  In this paper we present a novel approach for determining the possible refinements of an ontology-based query.  ...  Research for this paper was partially financed by BMBF in the project "SemiPort" (08C5939).  ...

2015 Indian Journal of Science and Technology  
, the Ranking part which arranges the documents based on the relevance and the matching part which compares the query representation with the document representation.  ...  The way in which the information is collected, shared and searched is changed drastically. Searching information has never been so easy because of the search engines.  ...  Properties of Web Queries As already analysed in the related work, based on user intent the queries are being classified based on the task they are deployed for.  ...

Ontology Based Query Expansion Using Word Sense Disambiguation [article]

M. Barathi, S. Valli
2010 arXiv   pre-print
This work is based on Word sense disambiguation, thesaurus WordNet and ontology of any domain for retrieving information in order to capture the context of particular concept(s) and discover semantic relationships  ...  New methods based on the semantics of user keywords must be developed to search in the vast web space without incurring loss of information.  ...  In order to refine the web search using ontology, both the k-cores and the ontology of a medical domain is used to enrich the user query for more efficient retrieval of web pages.  ...

Change Discovery in Ontology-Based Knowledge Management Systems [chapter]

Ljiljana Stojanovic, Nenad Stojanovic, Alexander Maedche
2003 Lecture Notes in Computer Science  
In this paper, we present an agent-based approach for the improvement of searching in an ontology-based knowledge management system.  ...  The system implements a library scenario in which users query the repository for knowledge resources.  ...  Based on these analyses, the agent, through an interactive dialogue, guides the users in more efficient searching for information.  ...
