AquaLog: an ontology-portable question answering system for the semantic web

Abstract: As semantic markup becomes ubiquitous, it will become important to be able to ask queries and obtain answers, using natural language (NL) expressions, rather than the keyword-based retrieval mechanisms used by the current search engines. AquaLog is a portable question-answering system which takes queries expressed in natural language and an ontology as input and returns answers drawn from the available semantic markup. We say that AquaLog is portable, because the configuration time required to customize the system for a particular ontology is negligible. AquaLog combines several powerful techniques in a novel way to make sense of NL queries and to map them to semantic markup. Moreover it also includes a learning component, which ensures that the performance of the system improves over time, in response to the particular community jargon used by the end users. In this paper we describe the current version of the system, in particular discussing its portability, its reasoning capabilities, and its learning mechanism.

Adapting BPEL4WS for the semantic web: the bottom-up approach to web service interoperation

Abstract: Towards the ultimate goal of seamless interaction among networked programs and devices, industry has developed orchestration and process modeling languages such as XLANG, WSFL, and recently BPEL4WS Unfortunately, these efforts leave us a long way from seamless interoperation Researchers in the Semantic Web community have taken up this challenge proposing top-down approaches to achieve aspects of Web Service interoperation Unfortunately, many of these efforts have been disconnected from emerging industry standards, particularly in process modeling In this paper we take a bottom-up approach to integrating Semantic Web technology into Web services Building on BPEL4WS, we present integrated Semantic Web technology for automating customized, dynamic binding of Web services together with interoperation through semantic translation We discuss the value of semantically enriched service interoperation and demonstrate how our framework accounts for user-defined constraints while gaining potentially successful execution pathways in a practically motivated example Finally, we provide an analysis of the forward-looking limitations of frameworks like BPEL4WS, and suggest how such specifications might embrace semantic technology at a fundamental level to work towards fully automated Web service interoperation

The Semantic Web Vision: Where Are We?

Abstract: Semantic Web developers have adopted OWL to represent knowledge. OWL, or a language with similar theoretical foundations, will lead the way in the semantic exploration of the Web. Currently, Web-based standards are the preferred way to represent knowledge. Furthermore, respondents mainly use ontologies to allow both humans and computers to understand knowledge and domain models. Web 3.0 can bring a new breed of spectacular applications compared to Web 2.0. with the same magnitude that separates Web 2.0 from Web 1.0.

Games with a Purpose for the Semantic Web

Abstract: Weaving the semantic Web requires that humans contribute their labor and judgment for creating, extending, and updating formal knowledge structures. Hiding such tasks behind online multiplayer games presents the tasks as fun and intellectually challenging entertainment. The games we've presented are the first prototypes of the OntoGame series. We're extending and improving the scenarios in several directions.
