Multifaceted approach to ontologizing the ONTOLOG content Rooted in pragmatism, tools, services, and standards, and social collaboration

Approach and thesis
Two key problems
– Lack of pragmatism in the goals of ontologies
– Heterogeneity of usage and use cases
Summary of approach
– Simple tagging for human collaboration (folksonomies) as well as rating systems for content parts
– Covert audio automatically into annotated text transcript
– Mining tools to automate annotation of content and infer taxonomies
– Ontology for outline of content
Secret sauce is in how we combine the semantics, i.e., algorithm, and the use cases we try to solve

Tagging and ratings – Human collaboration Tagging
– Idiosyncratic
– Results in bag of tags forming folksonomies
– Various available services, e.g., http://del.icio.us, http://flikr.com, and so on
– Need incentives for humans, e.g., easier search
– Evolving into some form of “ontology” (see Peter Mika’s paper “Ontologies are us: A unified model of social networks and semantics” at ICSW 2005)
Ratings
– Enables feedback
– Rate ratings to avoid collusion
– Similar to http://digg.com, Amazon’s rating system, and eBay.com reputation system (various works in literature)

Audio content
Automated transcript
– Use services to convert audio to text transcript
– Some services, e.g., http://podzinger.com, also annotate the transcript and do more than close captions
– May involve human collaboration to gradually improve content (especially resolving context errors)
Issues
– ONTOLOG audio (Podcast) have some low quality MP3
– Static noise and “voice storms”

Mining
Automatic annotation of content
– Mature tool set in UIMA
– Others (?)
– Generate initial taxonomy
– Continual process to update annotation
Dr. David Ferrucci (IBM Research) lead architect of UIMA project to present to community on May 11, 2006

Ontology
Outline
– Create initial outline of site content with some upper ontology
– Reuse existing ontology
IMO this ontology can be specific to ONTOLOG
What are the primary goals for this outline and ontology?
– Cataloguing
– Search (why not just use Google services?)
– Statistics (why not just use Amazon’s Alexa services?)
– Others (?)
