We had a wonderful session today with our invited speakers Mr. 
Jack Park (SRI) and Dr. Patrick Durusau (INCITS/V1) who presented 
their talk entitled: "Avoiding Hobson's Choice In Choosing An 
Ontology."    (01)

Our appreciation goes out to our speakers for sharing their work 
with us. We also want to thank Dr. Douglas Engelbart for joining 
us today, and introduced our speakers. And, as always, thanks to 
all the participants who joint us and contributed their valuable 
insights during the discussion following the presentation.    (02)

Proceedings of today's session are captured at our wiki page, at:

The digitized (mp3) audio recording and podcast of the entire 
session is available now. That will be archived in our knowledge 
repository for reference and download by anyone interested. See 
details at:
Mr. Park & Dr. Durusau's input today adds yet another important 
piece to this collective knowledge and intelligence that our 
community is building.    (04)

Best regards.  =ppy    (05)

>> Topic: *Avoiding Hobson's Choice In Choosing An Ontology*
>>    (014)

>> *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.    (016)

>> *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.
