In recent years, the number of educational resources stored in repositories of learning objects has increased. For recover them, generally traditional methods searching query terms that match the metadata of the learning objects are used. Precision in search results with these methods remains low. In this sense, this work focused on improving the precision indicator by applying Latent Semantic Analysis technique (LSA) over metadata that describe to learning object. This technique allows approximations for its meaning. In the experiment, it is shown an improvement in precision in the search, as more terms are entered in the query. The implementation could be extended to full-text searches of textual learning objects, if we have access to the...
