Hilog support for query literals
by Mark Proctor
Hilog supports something called "generic programs". You can think of
these as query literals you can pass around and call, bit like function
literals.
Because Hilog is untyped it uses a separate parenthesis to allow query
literals to be passed:
http://www.cs.sunysb.edu/~warren/xsbbook/node46.html
"... snip ....
closure(R)(X,Y) :- R(X,Y).
closure(R)(X,Y) :- R(X,Z), closure(R)(Z,Y).
Now given any binary relation, one can use use this definition to
compute its closure. For example, we can define a binary predicate,
|parent| as follows:
:- hilog parent.
parent(able,adam).
parent(able,eve).
parent(cain,adam).
parent(cain,eve).
etc
and then we can use the generic definition of closure to find anscestors:
| ?- clo
... snip ...."
We could supprt this if we added generics to our query literals, probably something like:
query closure( Query<String, String> q, String x, String y )
q( x, y )
or
( q( x, z ) and q(z, y) )
end
Anyway something worth thinking on, when we start to look at function literal support in Drools, we should probably address the two at the same time.

The Need to Relieve Constraints on Artificial Intelligence
<http://cts.vresp.com/c/?VisionArtsCommunicat/a0cdd8f89d/11698b4526/02fa31...>
Addressed at Rules Fest 2011
<http://cts.vresp.com/c/?VisionArtsCommunicat/a0cdd8f89d/11698b4526/17f81f...>
/Veteran AI Leaders Paul Haley and Said Tabet Slated to Address Developers /
/San Francisco, CA, August 2, 2011– /Organizers today posted the
abstracts for keynote speakers for Rules Fest 2011
<http://cts.vresp.com/c/?VisionArtsCommunicat/a0cdd8f89d/11698b4526/b2063d...>,
the International Conference on Reasoning Technologies, a conference by
developers for developers scheduled for the San Francisco Bay Area this
October 2011.
In a session titled “Roadmap for Rules, Semantics, and Business,” Paul
Haley
<http://cts.vresp.com/c/?VisionArtsCommunicat/a0cdd8f89d/11698b4526/819a3e...>,
who has been working to commercialize artificial intelligence for more
than three decades, says understanding the requirements for semantic
technology in enterprise vs. the capabilities of rules engines exposes
the need for more classic artificial intelligence and reasoning in our
technology, more emphasis on knowledge than rules in our services, and
more emphasis on knowledge technology strategy in the executive suite.
Haley will discuss the challenge that while semantic technology is
inevitably mainstream, it remains largely divorced from the activity of
knowledge engineering as practiced using business rule engines embedded
within business process management or complex event processing systems.
Semantic technology encodes meanings separately from data and content
files, and separately from application code. This enables machines as
well as people to understand, share and reason with them at execution
time. Semantic technologies make it easy to add, change and implement
new relationships or interconnecting programs in a different way. For
example, a context-aware, semantically-enabled system is able to
distinguish terms that are labeled differently but have the same
meaning, as well as terms that share the same label but have entirely
different meanings.
Cloud trust, information governance, risk management, and compliance,
distributed systems, mobile applications all offer a unique opportunity
to realize the true potential of knowledge technology. These systems are
usually covered by service level agreements that are rules-based.
Dr. Tabet’s discussion
<http://cts.vresp.com/c/?VisionArtsCommunicat/a0cdd8f89d/11698b4526/dff655...>,
“Semantic Technologies and the Cloud: Rules for the Next Generation,”
addresses the major challenges in information management while the
business environment also witnesses the drastic shift to cloud
computing. Dr. Tabet will address the trend of constraining artificial
intelligence and knowledge technologies in legacy environments, and says
enterprise knowledge management needs strong semantic technologies,
powerful inferencing systems, and advanced machine learning capabilities
– not more sophisticated spreadsheets. Dr. Tabet was a co-founder of the
RuleML Initiative in 2000, involved in artificial intelligence and its
applications for well over a decade. He recently refocused his efforts
on RuleML and Business Rules, XML, RDF and the Semantic Web as well as
deductive reasoning in financial services.
Rules Fest
<http://cts.vresp.com/c/?VisionArtsCommunicat/a0cdd8f89d/11698b4526/72cd85...>,
hosted by the non-profit Rules Fest Association, is a technical
conference geared toward software developers, engineers, programmers and
architects who create solutions to complex computing problems using
/reasoning technologies/
<http://cts.vresp.com/c/?VisionArtsCommunicat/a0cdd8f89d/11698b4526/6c855e...>:
rule-engines, logical reasoners, constraint-solvers, and other such
building-blocks of practical artificial intelligence (AI). More than 200
developers, engineers, programmers, and architectsfrom around the globe
are expected to attend the conference in Burlingame, California.
The conference will also feature a Career Center to address the war for
developer talent in technology companies. Companies seeking advanced
programming talent are invited to submit their open positions for
posting at no charge.
*Conference Fee and Package Pricing
*The standard fee for the conference is $499. All bootcamps –
addressing specific programming challenges and technologies -- are $299.
For a limited time, Rules Fest organizers are offering an early bird
rate of $1249 including an all-access conference pass, four nights at
the Hyatt Regency Burlingame, a boot camp of choice, and 10% off from
next year’s conference. This “early bird” rate is available until
September 30. Early discounts are also available for general admission
and for bootcamps without a hotel stay. To register, attendees should
visit the conference registration site
<http://cts.vresp.com/c/?VisionArtsCommunicat/a0cdd8f89d/11698b4526/c616b6...>
on the conference website.

Guvnor documentation
by Michael Anstis
Guvnor's documentation has been restructured, with coverage expanded
(admittedly to a number of "TODO" items).
Anybody fancy taking a look and checking it builds OK - git status shows
everything's committed, but confirmation from someone would be good :)
Feel free to complete any of the "TODO" sections over time too ;)
Cheers,
Mike
