Description
Summary:The primary goal of the ELIXIR project was to achieve improvements in the performance of text-retrieval systems by confronting some of the challenges presented by the indexing of full-text documents. We explored two hypotheses involving the use of linguistic analysis to improve the automatic creation of indexes: (1) if it is possible to develop algorithms that index only the words which most closely capture the document's content-not the complete text, as is done in existing sys-tems-the retrieval of irrelevant documents might be minimized; (2) if it is possible to create indexing algorithms that perform a minimal syntactic parse required to capture important phrases, the index may represent the document's content even more accurately, increasing the likelihood that the article can be retrieved by a relevant query.
