Hybrid approach combining contextual and statistical information for identifying MEDLINE citation terms

There is a strong demand for developing automated tools for extracting pertinent information from the biomedical literature that is a rich, complex, and dramatically growing resource, and is increasingly accessed via the web. This paper presents a hybrid method based on contextual and statistical information to automatically identify two MEDLINE citation terms: NIH grant numbers and databank accession numbers from HTML-formatted online biomedical documents. Their detection is challenging due to many variations and inconsistencies in their format (although recommended formats exist), and also because of their similarity to other technical or biological terms. Our proposed method first extracts potential candidates for these terms using a rule-based method. These are scored and the final candidates are submitted to a human operator for verification. The confidence score for each term is calculated using statistical information, and morphological and contextual information. Experiments c...
