Fabiano Tavares da Silva, Jose Everardo Bessa Maia . Luppar: Information Retrieval for Closed Text Document Collections. International Journal of Applied Information Systems. 12, 28 ( March 2020), 1-6. DOI=10.5120/ijais2020451846
This article presents Luppar, an Information Retrieval tool for closed collections of text documents which uses a local distributional semantic model associated to each corpus. The system performs automatic query expansion using a combination of distributional semantic model and local context analysis and supports relevancy feedback. The performance of the system was evaluated in databases of different domains and presented results equal to or higher than those published in the literature.
