JARAMILLO VALBUENA, Sonia  e  LONDONO, Jorge Mario. DOCUMENT SEARCH SUPPORTED ON AN ONTOLOGICAL INDEXING SYSTEM CREATED WITH MAPREDUCE. Cienc. Ing. Neogranad. [online]. 2014, vol.24, n.2, pp.57-75. ISSN 0124-8170.

This paper presents a search system supported on an ontological indexing system. The approach we present is based on lattice matching. The system performs a matching operation that takes as input a pruned lattice of ontological terms associated with the documents in a corpus and a query lattice. The matching process selects relevant documents and ranks them in accordance to their closeness to the user's query. We have implemented our approach on top of MapReduce. The experimental results support the efficacy of the system by providing users with a greater consistency among the results and the search domain. The results displayed to the users also show performance enhancements and improved accuracy. The test results are included at the end of the paper.
