N2  -  FACTA is a text search engine for MEDLINE abstracts, which is designed particularly to help users browse biomedical concepts (e.g. genes/proteins, diseases, enzymes and chemical compounds) appearing in the documents retrieved by the query. . The concepts are presented to the user in a tabular format and ranked based on the co-occurrence statistics. . Unlike existing systems that provide similar functionality, FACTA pre-indexes not only the words but also the concepts mentioned in the documents, which enables the user to issue a flexible query (e.g. free keywords or Boolean combinations of keywords/concepts) and receive the results immediately even when the number of the documents that match the query is very large. . The user can also view snippets from MEDLINE to get textual evidence of associations between the query terms and the concepts. . The concept IDs and their names/synonyms for building the indexes were collected from several biomedical databases and thesauri, such as UniProt, BioThesaurus, UMLS, KEGG and DrugBank. . AVAILABILITY: The system is available at http://www.nactem.ac.uk/software/facta/
