abstract = {Ontologies have become a key component in the Semantic Web
and Knowledge management. One accepted goal is to construct
ontologies from a domain specific set of texts. An ontology
reflects the background knowledge used in writing and reading a
text. However, a text is an act of knowledge maintenance, in that
it re-enforces the background assumptions, alters links and
associations in the ontology, and adds new concepts. This means
that background knowledge is rarely expressed in a machine
interpretable manner. When it is, it is usually in the conceptual
boundaries of the domain, e.g. in textbooks or when ideas are
borrowed into other domains. We argue that a partial solution to
this lies in searching external resources such as specialized
glossaries and the internet. We show that a random selection of
concept pairs from the Gene Ontology do not occur in a relevant
corpus of texts from the journal Nature. In contrast, a significant
proportion can be found on the internet. Thus, we conclude that
sources external to the domain corpus are necessary for the
automatic construction of ontologies.
