Description

OpenCyc will be more accessible and Semantic Web interoperability will be enhanced if users are able to access just the parts of OpenCyc they need. The tutorial will describe how Semantic Web researchers and practitioners can benefit from integrating their representations with the extensive upper and middle level ontological content of the free and unrestricted OpenCyc knowledge base, and other integrative vocabularies like Okkam. The syntax of OpenCyc will be described both in raw form, and as mapped onto Semantic Web standard languages, and the content of the knowledge base will be described in overview. Based on that, we’ll show how to extend the OpenCyc KB for user applications, and how to make use of it in a web-services environment to support knowledge integration, and simple machine learning applications. Finally, we’ll demonstrate the use of the OpenCyc vocabulary to support a broad-applicability knowledge capture application, illustrative of the transition from Web2.0 to Web3.0. Hands on exercises will be used to illustrate knowledge use and construction, use of OpenCyc with inference, and use for semantic search over text in a web services environment.

This recording is horrific and the constant cut-offs make it very hard to follow what the presenters are saying.

This player is really bad. It's constantly lagging and stuttering.


Comment4 Robert Zurunkle, February 9, 2014 at 5:47 p.m.:

And posting a comment takes me away from the player page. interrupting the playback. That's just horrible design.

Brilliant video lecture! Keep it up.


Comment7 Korio, January 8, 2024 at 9:23 a.m.:

Thank you for the convenient presentation of the material. You talk about this much simpler and more accessible than my professor. I'm very interested in continuing to study the Semantic Web in depth.

I'm new to this part of IT and haven't quite gotten the hang of data yet. Web network semantics is just an entry into my profession, so I have to look for additional help from time to time. This service is most often useful - https://cwassignments.com/ There are specialists here in almost any IT area. Such help is very useful when you are trying to understand a lecture on a new subject.
