It uses a network-based approach for identifying the concept represented by the user’s query and is founded on the idea that a collection-specific association thesaurus can be used to create a reasonable representation of all the concepts within the document collection...
متن کاملQuery reformulation with collaborative concept-based expansion
Most information retrieval systems on the Internet try to supply the ‘best’ documents to a certain query by ranking the complete hit list with various algorithms. But this is only appropriate if the hit list contain relevant documents which can be positioned on the top. In the case of a small or empty hit list no ranking can improve the result and the user must reformulate the query again and a...
متن کاملContextual and Concept-Based Interactive Query Expansion
In this paper, we present a novel approach for contextual and concept based query formulation in web-based information retrieval, which is an on-going PhD project being undertaken at the Software Engineering Research Lab (SERL) at Auckland University of Technology (AUT). Various query formulation approaches have been studied for a long time with varying degree of success. To the best of our kno...
