What are some of the benefits of ontology-based querying?
Clearly, the user now gets more relevant matches to queries (for example, searching for heart will also return articles about the ventricle). The user will also get more focused results because we provide a search only for articles that are annotated by MeSH headings or by users for these specific concepts (such as in the case of GOA). We do not provide keyword-based matches, so this will automatically exclude articles that might be irrelevant to the query. As an example, if a user wants articles about the GO process of respiratory tube development but enters it in a keyword search, he would get articles about children with respiratory infections needing tubes to prevent middle ear infections in development. And he will miss articles about lung development, which is part of the respiratory tube development process.
