Bioinformatics relies heavily on web resources for information gathering.
Ontologies are being developed to fill the background knowledge needed to
drive Semantic Web applications. This paper discusses how formal ontologies
are not always suited for document navigation on the web. Converting
ontologies into a model with looser semantics, allows cheap and rapid
generation of useful knowledge systems. The message is that ontologies are
not the only knowledge artefact needed; vocabularies and other classification
schemes with weaker semantics have their role and are the best solution in
certain circumstances
