Software module |
|
Intended to act as a proxy for you in some way |
|
May be: |
|
Tightly controlled |
|
Autonomous |
|
Mobile |
|
|
|
|
Humans work sequentially |
|
Agents work in parallel and 24x7 |
|
Therefore, agents can be a major productivity
multiplier |
|

|
|
Average Web searches examine only 25% of
available information |
|
Web searches return a lot of unwanted
information |
|
Information content of the Web doubles
approximately every six months |
|
Problem continues to worsen as Web grows |
|
|
|
|
Information on the World Wide Web is based on
HTML |
|
HTML is intended only for the visual
presentation of information for humans to understand |
|
The best you can do is some form of word lookup |
|
There is no syntactic, semantic or logic
description of the information |
|
Information is not machine readable |
|
|
|
|
|
|
|
World Wide Web Consortium (W3C) standard |
|
Provides important solution to syntax problem
and simple semantics and schemas: |
|
<SSN>444-23-2656</SSN> |
|
Now we can describe the meaning of words |
|
Many applications of XML appearing: |
|
Geographic Markup Language (GML) |
|
Extensible rights Markup Language (XrML) |
|
Chemical Markup Language (CML) |
|
|
|
|
Builds on top of XML and RDF |
|
Provides rich ontology representation |
|
Key starting point for W3C Semantic Web activity |
|
Future releases will provide logic and rules
capabilities |
|
|
|
|
|
|
|
DAML ontology language specification released |
|
http://www.daml.org provides public Web site
with DAML information |
|
18 top-level research teams are developing DAML
technology |
|
Including Tim Berners-Lee (creator of web) |
|
Dan Connolly (key developer of XML) |
|
Supported by W3C their new Semantic Web Activity |
|
|
|
|
|
|
DAML has the potential to revolutionize the way
we use the Web |
|
As the Semantic Web infrastructure grows it will
result in major improvements in human access to information |
|
Agents will act as real functional proxies for
people and greatly increase their productivity |
