Contexts and Ontologies:Theory, Practice and Applications 

Contexts and Ontologies:Theory, Practice and Applications: "General Information and Workshop Goals
Ontologies are shared models of a domain that explicitly encode a view which is common to a set of different parties. Contexts are local models which explicitly encode one party's subjective view of a domain.
During the last decade, there has been a line of successful series of workshops and conferences on the development and application of contexts and ontologies. Early workshops were focused mostly on identifying what contexts and ontologies are, and how they can be formalized and exploited. In more recent years with the emergence of distributed systems (e.g., P2P systems, Semantic Web) the focus of workshops shifted towards questions of practical applications, such as semantic integration, coordination, and meaning negotiation among information sources, where both contexts and ontologies were applied as promising solutions. However, few, if any, of these meetings have focused on combining the themes of ontologies and contexts and discussed them as complementary disciplines."

DIP Integrated Project 

DIP Integrated Project: "Vision
DIP's objective is to develop and extend Semantic Web and Web Service technologies in order to produce a new technology infrastructure for Semantic Web Services (SWS) - an environment in which different web services can discover and cooperate with each other automatically. DIP's long term mission is to deliver the enormous potential benefits of Semantic Web Services to e-Work and e-Commerce. "

DIP project submits WSMO to W3C's Semantic Web committee. News - WebServices.Org: "The DIP project -- Data, Information, and Process Integration with Semantic Web Services -- recently submitted WSMO to the W3C's consideration as a comprehensive framework for addressing Semantic Web services challenges and designed to overcome the current problems of enterprise application integration (EAI).
"It [WSMO] contributes substantially to solving one of the most difficult and costly problems in IT, namely allowing disparate systems to share and integrate information in a cost effective way," says Professor Dieter Fensel, Scientific Director of DERI. "This is a perennial problem for companies and represents billions of dollars in technology spending, with around 30 per cent of worldwide IT budget dedicated to integration efforts. This technology will enable organisations to make substantial savings in their IT investments and increase their agility in changing business processes according to market needs." "

An API for ontology alignment 

An API for ontology alignment (version 1.3)

Ontologies are seen as the solution to data heterogeneity on the web. However, the available ontologies are themselves source of heterogeneity. This can be overcome by aligning ontologies, or finding the correspondence between their components. These alignments deserve to be treated as objects: they can be referenced on the web as such, be completed by an algorithm that improves a particular alignment, be compared with other alignments and be transformed into a set of axioms or a translation program. We present here a format for expressing alignments in RDF, so that they can be published on the web. Then we propose an implementation of this format as an Alignment API, which can be seen as an extension of the OWL API and shares some design goals with it. We show how this API can be used for effectively aligning ontologies and completing partial alignments, thresholding alignments or generating axioms and transformations."

AAAI Spring 2006 Symposia :: Computational Approaches to Analysing Weblogs 

AAAI Spring 2006 Symposia :: Computational Approaches to Analysing Weblogs: "Introduction
Weblogs are web pages which provide unedited, highly opinionated personal commentary. Often weblogs (also referred to as blogs) are chronological sequences of entries which include hyperlinks to other resources. Blogs are conveniently maintained and published with authoring tools.
The blogosphere as a whole can be exploited for outreach opinion formation, maintaining online communities, supporting knowledge management within large global collaborative environments, monitoring reactions to public events and is seen as the upcoming alternative to the mass media.
Semantic analysis of blogs represents the next challenge in the quest for understanding natural language. Their light content, fragmented topic structure, inconsistent grammar, and vulnerability to spam makes blog analysis extremely challenging when faced with questions like: can the implicit and explicit communities implied by content and link structure be used to determine the relevance and influence of bloggers? Can a blog segment be identified as a summary of a linked story in order to use both as training data for summarization research? Can we determine how information percolates through mass media outlets and blogs? Can blogs with multimedia content be stored in a way that allows us to search across different modalities? Can we find consumer complaints, discover vulnerabilities of products, and predict trends?"

FlockBots : Home 

FlockBots : Home: "This website describes an open design for a small, $800 robot suitable for 'swarm'-style multiagent research, robotics education, and other tasks. Our goal is to get as much functionality as possible from $800 per robot, replicate the robot many times to create a small collaborative swarm, and document the results to make it easier for you to do the same. We hope to foster collaboration in the wider community and, ultimately, lower the entry-level costs for building such robots. "
