  • Patent number: 7403891
    Abstract: The present invention relates to an apparatus and method for recognizing biological named entity from biological literature based on united medical language system (UMLS). The apparatus and the method receives metathesaurus from the UMLS, constructs a concept name database, a single name database and a category keyterm database, which are language resources to be used recognize a named entity, receives each concept name stored in the concept name database, extracts features of each of the concept names by using data stored in the single name database and the category keyterm database, constructs a rule database by creating rules used to recognize the named entity and filtering the rules by using the extracted features, receives a biological literature, extracts nouns and noun phrases that are candidate named entities, applies the rules stored in the rule database to the nouns and the noun phrases, and recognizes the named entities.

  • Publication number: 20080082483
    Abstract: Provided is a method and apparatus for normalizing a protein name using ontology mapping. A method for normalizing a protein name using ontology mapping, which includes the steps of: a) extracting a protein name from an input of a biological article; b) analyzing a protein code corresponding to the protein name by calculating similarities between the protein name and synonyms of a synonym dictionary created through an ontology; c) classifying protein species information included in the biological article using a predetermined species classification learning model; and d) assigning an ontology identification (ID) created by combining the analyzed protein code and the classified protein species information to the protein name.
