OBJECTIVE: Healthcare communities have identified a significant need for
disease-specific information. Disease-specific ontologies are useful in assisting
the retrieval of disease-relevant information from various sources. However,
building these ontologies is labor intensive. Our goal is to develop a system for
an automated generation of disease-pertinent concepts from a popular knowledge
resource for the building of disease-specific ontologies. METHODS: A pipeline
system was developed with an initial focus of generating disease-specific
treatment vocabularies. It was comprised of the components of disease-specific
citation retrieval, predication extraction, treatment predication extraction,
treatment concept extraction, and relevance ranking. A semantic schema was
developed to support the extraction of treatment predications and concepts. Four
ranking approaches (i.e., occurrence, interest, degree centrality, and weighted
degree centrality) were proposed to measure the relevance of treatment concepts
to the disease of interest. We measured the performance of four ranks in terms of
the mean precision at the top 100 concepts with five diseases, as well as the
precision-recall curves against two reference vocabularies. The performance of
the system was also compared to two baseline approaches. RESULTS: The pipeline
system achieved a mean precision of 0.80 for the top 100 concepts with the
ranking by interest. There were no significant different among the four ranks
(p=0.53). However, the pipeline-based system had significantly better performance
than the two baselines. CONCLUSIONS: The pipeline system can be useful for an
automated generation of disease-relevant treatment concepts from the biomedical
literature.
