Semantic Wikis Visual Knowledge, Inc. Ontologizing the Ontolog Forum Where do Semantic Wikis fit? Conor Shankey CEO July 6, 2006 Visual Knowledge, Inc. 1/16/2019
Overview A key platform for the Ontolog Forum is the CIM3 Wiki The Ontolog Forum is a Community of Interest/Practice Overview of Semantic Wiki Proposal: 80 / 20 rule start by “ontoligizing” or structuring the most important things in the Forum Utilize a semantic wiki to let the community convert unstructured knowledge into structured knowledge 1/16/2019
The Ontolog Forum Ontolog wiki is the central platform for organizing Meetings/Presentations Discourse Information about people Presentations, Documents, Audio Files, Ontologies Focal Points appear to be regular presentations Key “concepts” are all hyperlinked via wiki words Works extremely well by letting community collaboratively integrate knowledge Hard to find things of interest if you don’t know where something is you resort to hunting and word searching 1/16/2019
The original wiki idea “A web site where anybody could create/edit a web page” Structure is not pre-determined invented & evolved by community neither top down or bottom up Quick collaborative writing Non-linear Hypertext 1/16/2019
Simplicity Additional Notions Very simple markup for authors Any page can be immediately revised assuming you have the right privileges All changes are audited and transparent to the community “Concepts” in text can immediately become active resources (pages/links) Simplicity 962 000+ articles 1/16/2019
Benefits of the wiki idea Distinct concepts or topics are built on the fly Discourse forms around or in the context of a topic Eliminates serialized document work flow Team or community members can immediately see commentary in the context of a topic Consensus Agility Cohesion Speed 1/16/2019
Limitations for Open Forum? Topics or concepts lack semantics A WikiWord is just a WikiWord The forum is a flat network of anonymous concepts Concepts lack type or the ability to describe common properties Lack of common properties inhibits ability to Search for events through a calender, date criteria, subject or presenter Quantify value of resources based on usefulness, subject area, application area 1/16/2019
Semantics to the rescue Different concepts have different properties Unique attributes like date, start/end time, audience rating, etc. Modification date Unique Relationships Presenter Attendees Creator Resources related to subject area Ability to organize concepts based on classification mechanism Aggregation of complex concepts “Is Part Of” types of relationships 1/16/2019
Semantics to the rescue Phrases having different meanings in different contexts Water on mars? Food Space Exploration 1/16/2019
VK Semantic Wiki Wiki concepts are just elements of an ontology Now wiki concepts have formal properties Enables semantic searching Security becomes deeply integrated into wiki Customized Wiki Views Driven by ontology Driven by library of visual templates Integrated change management Federated semantic wikis 1/16/2019
Proposal – 80/20 rule Start with the easy stuff Events People “Black Box” Documents Powerpoints, audio files, PDFs Identify basic properties Structure key items iteratively Created faceted search ability to find most useful skeletal information Let the community grade, rate and organize properties on resources, presenters, etc.. 1/16/2019
