>> Topic: *Avoiding Hobson's Choice In Choosing An Ontology*
>> *Abstract*: (by Jack Park & Patrick Durusau)
>> Most users of ontologies have either participated in the development 
>> of the ontology they use and/or have used it for such a period of 
>> time that they have taken ownership of it. Like a hand that grows to 
>> fit a tool, users grow comfortable with "their" ontology and can use 
>> another only with difficulty and possibly high error rates.
>> When agencies discuss sharing information, the tendency is to offer 
>> other participants a "Hobson's Choice" of ontologies. "Of course we 
>> will use ontology X." which just happens to be the ontology of the 
>> speaker. Others make similar offers. Much discussion follows. But not 
>> very often effective integration of information.
>> In all fairness to the imagined participants in such a discussion, 
>> unfamiliar ontologies can lead to errors and/or misunderstandings 
>> that may actually impede the interchange, pardon, the accurate 
>> interchange information. Super-ontologies don't help much when they 
>> lack the granularity needed for real tasks and simply put off the day 
>> of reckoning when actual data has to move between agencies.
>> The Topic Maps Reference Model is a paradigm for constructing a 
>> mapping of ontologies that enables users to use "their" ontologies 
>> while integrating information that may have originated in ontologies 
>> that are completely foreign or even unknown to the user. Such 
>> mappings can support full auditing of the process of integrating 
>> information to enable users to develop a high degree of confidence in 
>> the mapping.
>> Topic maps rely upon the fact that every part of an ontology is in 
>> fact representing a subject. And the subject that is being 
>> represented is known from the properties of those representatives. 
>> Such representatives are called subject proxies in the Topic Maps 
>> Reference Model. Those properties are used as the basis for 
>> determining when two or more subject proxies represent the same 
>> subject. Information from two or more representatives of the same 
>> subject can be merged together, providing users with information 
>> about a subject that may not have been known in their ontology.
>> Park and Durusau explore the philosophical, theoretical and practical 
>> steps needed to avoid a Hobson's Choice in ontology discussions and 
>> to use the Topic Maps Reference Model to effectively integrate 
>> information with a high degree of confidence in the results. All 
>> while enabling users to use the ontology that is most familiar and 
>> comfortable for them.
>> *About the Speakers*:
>> *Mr. Jack Park* is a research scientist in the AI Laboratory at SRI, 
>> International in Menlo Park. He works with Adam Cheyer's integration 
>> team on the DARPA-funded CALO project, where he created the prototype 
>> from which the team evolved the IRIS desktop knowledge workstation. 
>> During employment with VerticalNet, Park served on the XTM Authoring 
>> Committee which created the XTM topic maps specification, now a part 
>> of the ISO 13250 Topic Maps standard. In a former life, while serving 
>> as the president of the American Wind Energy Association, Park was 
>> constructing microprocessor-based weather stations used for siting 
>> wind energy farms and in agricultural applications. The massive 
>> amounts of data being collected by those stations led to 
>> investigations into AI applications in data mining and data 
>> organization. Ontologies and inference engines naturally followed. 
>> Park has crafted Java-based inference engines for a large banking 
>> enterprise, a clinical informatics enterprise, and participated in 
>> the construction of the VerticalNet B2B ontology editor. Park 
>> authored _The Wind Power Book_ in 1981, and co-authored and edited 
>> _XML Topic Maps: Creating and Using Topic Maps for the Web_, 
>> published in 2002. He has taught university courses in renewable 
>> energy resources in the U.S., and lectured on those subjects in the 
>> U.S., parts of Europe and Africa. He spends most of his time now 
>> evolving applications for subject maps related to the Douglas 
>> Engelbart call for continuous improvement of human capabilities.
>> *Dr. Patrick Durusau* is the Chair of V1, the US Technical Advisory 
>> Group (TAG) to ISO/IEC JTC 1/SC 34, the committee responsible for the 
>> development of the Topic Maps family of standards. He is a co-editor 
>> of ISO 13250-5, the Topic Maps Reference Model. . . . In the Fall of 
>> 2006 he will be teaching what is thought to be the first graduate 
>> course devoted exclusively to topic maps at the School of Library and 
>> Information Science at the University of Illinois at 
>> Urbana-Champaign. . . . He is deeply interested in the integration 
>> diverse information systems (including ontologies) while preserving 
>> the ability of users to identify the subjects of their conversations 
>> in ways that work best for them.
>> *Refer to details on the session wiki page at*:
>> http://ontolog.cim3.net/cgi-bin/wiki.pl?ConferenceCall_2006_04_27
>> This will be a virtual session over an augmented conference call. The 
>> session is expected to start with 45 min. ~ 1 Hour presentation 
>> followed by an extended discussion between the participants and the 
>> speaker. The entire session will be recorded and made available as 
>> open content under the prevailing Ontolog IPR policy (see: 
>> http://ontolog.cim3.net/cgi-bin/wiki.pl?WikiHomePage#nid32).
>> As usual, this Ontolog event is open to all. I look forward to having 
>> you at this session. Please pass the announcement along to those who 
>> might be interested to join us too.
