With the increase in interest in web based e-commerce, the amount of business that is transacted on-line and the explosion in the amount of services available, the ability to

environments such as those enabled by the semantic web and pervasive computing technologies. The presence of heterogeneous entities that
are neither pre-determined nor permanent, and the lack of central
control are some of its challenges.  We believe that declarative
policies address this problem while maintaining openness and
flexibility.  We propose the use of policies defined in OWL to

A second generation Semantic Web will be built by adding semantic annotations that software can understand and from which humans can benefit.

  <description><![CDATA[We present a query algebra that supports optimized access of Web services through service-oriented queries. The service query algebra is defined based on a formal service model that provides a high-level abstraction of Web services across an application domain. The algebra defines a set of algebraic operators. Algebraic service queries can be formulated using these operators. This allows users to query their desired services based on both functionality and quality. We provide the implementati...]]></description>

As exemplified in Wikipedia, online collaborative information repositories are being generated, updated, and maintained by a large and diverse community of users. Issues concerning trust arise when content is generated and updated by diverse populations. Since these information repositories are constantly under revision, trust determination is not simply a static process. In this paper, we explore ways of utilizing t...]]></description>

Some current popular repositories contain contributions from a wide

that was previously contributed by a known user may be updated
by an unknown user. End users are now faced with more

finding all supporting sources and rejecting all irrelevant ones, but
neither RDF document nor triple is appropriate. Therefore, we approach
this goal using lossless decomposition of RDF graph at RDF molecule
granularity, which is the finest and lossless sub-graph of an RDF
graph. We also implements three decomposition strategies a prototype

  <description><![CDATA[The Platform for Privacy Preferences (P3P) is a W3C standard that websites can use to describe their privacy practices.  The presence of P3P policies enable users to configure web browsers to constrain what they can and cannot do when visiting websites.  It's a good idea that unfortunately is rarely used.  We identify two reasons: (i) the languages available to define a user's privacy preferences are not very expressive and (ii) most websites do not have published P3P policies.

In cyberspace, socializing the traditionally isolated intelligent software agents is an ultimate goal of the emerging Semantic Web activity.

  <description><![CDATA[The Semantic Web enables intelligent agents to ``outsource''
knowledge, extending and enhancing their limited knowledge bases. An
open question is how agents can efficiently and effectively access the
vast knowledge on the inherently open and dynamic Semantic Web. The
problem is not that of {em finding} a source for desired information,
but deciding which among many possibly inconsistent sources is most
reliable.  We propose an approach to agent knowledge outsourcing

across domains that handles complex inter domain trust relationships. We have developed a flexible representation of trust
information in Prolog, that can model permissions and delegations. We are currently working on modeling obligations,
entitlements, and prohibitions as well. This paper describes a scheme for restricting re-delegation without using a specific

  <description><![CDATA[The problem of data management has been studied widely in the field
of mobile ad-hoc networks and pervasive computing. An issue is that
finding the required data depends on chance encounter with the
source of data. Most existing research take the semantics of data
into account while caching data onto mobile devices from the wired
sources. In this work, we propose that the mobile devices decide
what to cache based on the queries they encounter. The scheme
involves a distributed techniqu...]]></description>

  <description><![CDATA[There is a growing interest in exploring the role of social networks for understanding
how communities and individuals spread influence. In a densely connected world where
much of our communication happens online, social media and networks have a great potential in influencing our thoughts and actions. The key contribution of our work is generation of a fully-connected polar social network graph from the sparsely connected social network graph in the context of blogs, where the vertex repre...]]></description>

  <description><![CDATA[Social Media such as blogs, wikis, formus and user-generated content
sites like flickr,
delicious and youtube have become both a source of information and
entertainment.
The size of audience that these sites currently yield is already rivaling
traditional main stream media sources like television, newspapers and
magazines.
Blogs, especially, have been reported to play a notable role in
influencing the buying patterns of consumers. Often a buyer looks for
opinions, user experiences an...]]></description>

  <description><![CDATA[Autonomous agents in heterogeneous, open systems face the
difficult problem of establishing and maintaining beneficial
relationships. Open social networks -- whether composed of
humans, machines, or some combination -- give rise to a need
for modeling inter-agent trust and reputation. A means to
guard against other agents failing to meet their commitments
is crucial. Such environments typically have no effective
mechanism for authority or enforcement. Lacking an
enforcement mechanism,...]]></description>
