Besides, does not detect differences context in ambiguous terms, what reduces precision results. The objective our research evaluate applicability paradigm information retrieval educational resources. We built an system follows approach and evaluated it with final users. main contribution this paper description architecture system. First evaluation results show based on works well retrieving practical implications are that: demonstrates workable build systems they efficient This makes them priori interesting be applied other domains.
