Abstract:
1. A method for recognizing a biological named entity from biological literature based on United Medical Language System (UMLS), the method comprising the steps of: (a) receiving metathesaurus from the UMLS; (b) extracting concept names, single names and category keyterms; (c) constructing a concept name database, a single name database and a category keyterm database; (d) constructing a database of rules based upon information stored within the concept name database, the single name database, and the category keyterm database; (e) inputting a literature; (f) extracting candidate named entities from the literature; and (g) recognizing named entities from the candidate named entities based upon the rules applied against the single name and category keyterm databases, wherein the step (b) comprises the steps of: (b-1) mapping information in MRCON table used to describe meaning of each string representing the concept name to information in MRSTY table used to describe a semantic category allocated to each concept name among tables included in the metathesaurus by using a mapping condition, and dividing data stored in the MRCON table according to each semantic category; (b-2) extracting values in a string (STR) field of the MRCON table from result of dividing a concept set and storing the extracted values in the concept name database; (b-3) extracting single names from the concept name database and storing the extracted single names in the single name database; and (b-4) extracting category keyterms from the concept name database and storing the extracted category keyterm in the category keyterms database.
