....for different purposes to those set out here. Ontologies can assist the extraction of concepts from unstructured textual documents [16] by serving as a source of knowledge about the particular topic. Ontologies can also assist in managing document descriptions in large digital libraries [43] [44]. Finally, our proposal builds on the use of automated pre print servers for the submission and dissemination of documents (e.g. the Los Alamos server for physics and computer science xxx.lanl.gov , or the CogPrints server for cognitive science cogprints.soton.ac.uk ) Hierarchical taxonomies ....

....for different purposes to those presented here. Ontologies can assist the extraction of concepts from unstructured textual documents [20] by serving as a source of knowledge about the particular topic. Ontologies can also assist in managing document descriptions in large digital libraries [61]. We noted earlier the emergence of open e print server architectures. A ScholOnto server as proposed here extends this infrastructure by adding a semantically enriched layer of document encoding, with associated services as discussed. A strategy for migrating from a conventional 24 e print (or ....

....and distinguishes formal ontology from other approaches. It then describes the UMDL ontology of bibliographic relations for digital library content. A more detailed description of the process of developing the UMDL ontologies and their use in the UMDL is available in Weinstein and Alloway [20]. Concept descriptions in stylized natural language, and definitions in Loom, are also available on the Web. 2 2.1 Formal Ontology In artificial intelligence, an ontology is a set of vocabulary definitions that expresses a community s consensus knowledge about a domain. This knowledge is meant ....

....as genre (we use upper case to reference ontology concept definitions, as opposed to their meaning in the world) From this experience, we learned two important lessons. First, we need to find ways to make ontological definition easier. This problem is discussed further in Weinstein and Alloway (Weinstein and Alloway 1997). Second, we believe that any attempt to impose a single conceptualization on all digital libraries is bound to fail. We do 1 http: www.umich.edu peterw Ontology ontology.html.

....instances (Lehmann and Cohn 1994) shared concepts (Campbell and Shapiro 1995) or shared parents from which terms in the source and target ontologies inherit. Currently, we adapt the latter approach by assuming a restricted form of semantic heterogeneity that we call differentiated ontologies (Weinstein 1997). Concepts in differentiated ontologies are not shared, but inherit definitional structure from concepts that 31 are shared. Hypothetically, a society of agents starts with all agents subscribing to the same ontologies. Over time, new, increasingly specialized agents join the society, and these ....

....knowledge that can be reused to address multiple problems. Philosophically, almost everything is a natural kind and requires definition as a primitive. In practice, it is always possible to develop non primitive definitions for those concepts that are the focus of effort. Weinstein and Alloway (Weinstein and Alloway 1997) includes discussion of the issue of the difficulty of developing formal ontologies. 9 Conclusions To support communication despite semantic heterogeneity, we use differentiated ontologies. In these structures, concepts are defined in relation to other concepts using logic. Local concepts ....
