- In the area of information retrieval, the dimension of document vectors plays an important role. Firstly, with higher dimensions index the indexing structures suffer from the %22curse of dimensionality%22 and their efficiency rapidly decreases. Secondly, we may not use exact words when looking for a document, thus we miss some relevant documents. LSI (Latent Semantic Indexing) is a numerical method, which discovers latent semantic in documents by creating concepts from existing terms. In this article we present a basic method mapping LSI concepts on given ontology - WordNet, used both for retrieval recall improvement and dimension reduction. We offer experimental results for this method on a subset of TREC collection, consisting of Los Angeles Times articles.
