The Rule Responder SymposiumPlanner system supports topic-oriented collaboration between the distributed members of a virtual organization. Each member (or small team of members) is assisted by a semi-autonomous rule-based personal agent, which uses Semantic Web rules to capture aspects of the member’s (or team’s) derivation and reaction logic. SymposiumPlanner is a series of Rule Responder use...

Rule Responder is an intelligent multi-agent system for collaborative teams and virtual communities that uses RuleML as its rule interchange format. The system allows these virtual organizations to collaborate in an effective semi-automatic manner, and is implemented as a Web-based application on top of the Enterprise Service Bus Mule. It supports rule execution environments (rule/inference eng...

This paper presents an approach for the specification and implementation of e-contracts for Web monitoring. This is done in the setting of RuleML. We argue that monitoring contract execution requires also a logical account of deontic concepts and of violations. Accordingly, RuleML is extended to cover these aspects. 1 Background and Motivation Business contracts are mutual agreements between tw...

The COntext INterchange (COIN) approach to information integration [Goh et al, 1999] [Bressan et al, 2000] [Firat et al, 2002] uses ontological mappings and enables powerful context-sensitive query mediation for semantic integration of knowledge across multiple heterogeneous database sources. Its existing applications include financial analysis for the financial services industry, as well as ai...

One of the main goals of the Semantic Web initiative [3] is to extend the current Web technology to allow for the development of intelligent agents, which can automatically and unambiguously process the information available on millions of web pages. It has been recognized very early in the development of the Semantic Web that rules are essential for the Web3 and for Semantic Web applications—e...

Fuzzy Cognitive Map (FCM) technique is broadly used for decision making and predictions by experts and scientists of a wide range of disciplines. The use of the FCMs would be even wider if a standardized representation of FCMs was developed and a system that would simulate them was constructed. Having such a system, decision makers would be able to create and examine their own developed Fuzzy C...

Abstract BaseVISor is a forward-chaining inference engine based on a Rete network optimized for the processing of RDF triples. A clause within the body and head of a rule either represents an RDF triple or invokes a procedural attachment (either built-in or ...

Defeasible reasoning is a rule-based approach for efficient reasoning with incomplete and inconsistent information. Such reasoning is useful for many applications in the Semantic Web, such as policies and business rules, agent brokering and negotiation, ontology and knowledge merging, etc., mainly due to interesting features, such as conflicting rules and priorities of rules. However, the RuleM...

In April 2013, the International Consortium of Investigative Journalists (ICIJ) exposed the details of 130,000 offshore accounts. Although there are legitimate businesses which use such accounts, there exist a number of accounts which are possibly linked to international tax fraud and money laundering. The ICIJ investigation was based on 2.5 million records of offshore holdings linked to 170 co...
