DESCRIPTION

Topic Maps (TM) standard has solved a lot of problems in the information overload. With a semantic layer on the top of the existing data pools, TMs provide user-specific information interpretation and organization. However, one important component is missing in the TM standard and usage. This paper introduces SocioTM model; an extension of TM paradigm that includes relevancies, collaboration, and socio-knowledge (user-specific knowledge/behaviors) within TMs. The paper goes through relevancies implementation in SocioTM, relevancies building and population in SocioTM, relevancies interpretation, presentation, and navigation through SocioTM. Relevancies are presented on two levels: topic/ontology level and information (occurrences) level. The paper concludes with collaboration involvement in SocioTM building and with migration of socio-knowledge.

• Users are interested in– Browsing in meta-data

(knowledge) space• not information space

– Topics that are more relevant

• Users are looking for– not only knowledge but also– something cool, interesting,

exciting, unknown

• » la science pour la science «– Knowledge Isolation

• TM knowledge is hard-typed, it is not fuzzy

User/Our Objectives

Page 4: SocioTM – Relevancies, Collaboration, and Socio-knowledge in Topic Maps

• Ubiquity phenomena• No talk about recommenders

– Google news, Amazon, MovieLens, etc

• Ranking topics of – the same class– different classes

Relevancies, Ranking, Recommenders

Page 5: SocioTM – Relevancies, Collaboration, and Socio-knowledge in Topic Maps

• Ranking support in TM– Scopes– Associations

• Problems– Binary-like concepts– Hardcoded in ontology space

• More fuzzy and general concept is needed

State of The Art

1. Information and meta-data space huge and highly interconnected

2. Interconnections important for user3. No need for real-time knowledge rebuilding4. Need for structural concept of knowledge5. Users:

a) Need data ranking and data recommendationsb) Need to individually affect knowledge andc) Preferably even globallyd) Able to migrate with aggregated socio-knowledge

Problem setting

SocioTM modelSocioTM modelOur approachOur approach

• Relevancies on – Occurrence and

– Topic map constructs• Behavioral prediction• Socio-knowledge migration

• Global knowledge structure building

• Unique vs. global knowledge• Mountain view

• View-clipping7/16www.SocioTM.com, TMRA 2008, Leipzig

Relevance Evolution/Normalizing

• Building dynamic SocioTM– As copy of topic space– On-the-fly

• Wide normalization– User profile– Short-term user interests– Search-item– User explicit socio-knowledge

• Normalizing through navigation and time

• Blue Circle – search location• Red Ring – browsing location• a) - initial position, b) after fist navigation step• a1, b1) - non-evaluated, a2, b2) – evaluated

• Socio-knowledge migration• Needs for pre-populated user preferences for

a new TM• Needs for global understanding user behaviors

Collaboration within Topic Maps

• Introducing SocioTM into the existing systems

• Vertical compatibility• Standardizing interface• Proxy implementation

SocioTM Implementation

www.SocioTM.com, TMRA 2008, Leipzig15/16

Page 16: SocioTM – Relevancies, Collaboration, and Socio-knowledge in Topic Maps

• Extend/add to TM standard • not just a business-logic module• Introducing fuzzy, multy-view knowledge• Living, user-affected knowledge

Conclusion

www.SocioTM.com, TMRA 2008, Leipzig16/16

Page 17: SocioTM – Relevancies, Collaboration, and Socio-knowledge in Topic Maps

• There is no standard defect but it is extension• Should we bother other users with our

opinions?• Why it should be standard and not just

business logic on the top of it?

Opened (?) Questions
