Motivation
The web has made people smarter and more capable
![Page 3: Making Software Agents Smarter](https://reader030.vdocuments.site/reader030/viewer/2022020111/56812ca7550346895d9150b7/html5/thumbnails/3.jpg)
Motivation
It provides easy access to most of the world's knowledge and services

Motivation
Web standards, protocols & technology work better than earlier distributed infor-mation system technologies

But what about our agents?

Agents still have a very minimal under-standing of text, images and video

Software agents need better access to a Web of knowledge to amplify their intelligence and knowledge

Key technologies: Semantic Web, linked data, text information extraction, Wikipedia derived KBs, etc.

ACLs
• Agents and knowledge has been a focus of agent communication languages (ACLs)
• Much of the ACL work has focused on primitives, protocols and infrastructure
• Less attention has been applied to finding, sharing and integrating ontologies, common background data, and populating KBs from the Web

Linked data and Wikipedia• Wikipedia as a source of knowledge
– Wikis are an effective tool for building know-ledge resources: consensus driven, dynamic, high quality and free
• Wikipedia as an ontology– Every Wikipedia page is a concept or object
• Wikipedia as RDF data– Map this ontology into RDF
• DBpedia as the lynchpin for Linked Data– Exploit its breadth of coverage to integrate
information

Linked Data on the Web, 3/09

Wikipedia is the new Cyc
• There’s a history of using ency-clopedias to develop KBs
• Cyc’s original goal (c. 1984) wasto encode the knowledge in adesktop encyclopedia
• And use it as an integrating ontology
• Wikipedia is comparable to Cyc’s original desktop encyclopedia
• But it’s machine accessible and malleable

Populating Freebase KB

Conclusion, for now
• The web has made people smarter and more capable, providing easy access to the world's knowledge and services
• Software agents need better access to a Web of knowledge to amplify whatever intelligence they have
• Some key technologies are ready to exploit: Semantic Web, linked data, DBpedia, Wikitology, etc.
