- 109 abstract "Rules and Automated Reasoning, Rules, Agents and Norms, Vocabularies, Ontologies, and Business rules Abstract: We present a description of the PhD thesis which aims to propose a rule-based query answering method for relational data. In this approach we use an additional knowledge which is represented as a set of rules and describes the source data at concept (ontological) level. Queries are posed in the terms of abstract level. We present two methods. The first one uses hybrid reasoning and the second one exploits only forward chaining. These two methods of the rule-based query answering are demonstrated by the prototypical implementation of the system coupled with the Jess engine. Tests are performed on the knowledge base of the selected economic crimes: fraudulent disbursement and money laundering.".

- 16 abstract "The ultimate vision of the Semantic Web is to offer an interoperable and information-rich web environment that will allow users to safely delegate complex actions to intelligent agents. Much work has been done for agents' interoperability; a plethora of proposals and standards for ontology-based metadata and rule-based reasoning are already widely used. Nevertheless, the SW proof layer has been neglected so far, although it is vital for SW agents and human users to understand how a result came about, in order to increase the trust in the interchanged information. This paper focuses on the implementation of third party SW reasoning and proofing services wrapped as agents in a multi-agent framework. This way, agents can exchange and justify their arguments without the need to conform to a common rule paradigm. Via external reasoning and proofing services, the receiving agent can grasp the semantics of the received rule set and check the validity of the inferred results.".

- 18 sameAs 18.
- 18 abstract "Users often enter a local expression to constrain a web search to a geographical place. Current search engines’ capability to deal with expressions such as “close to” is, however, limited. This paper presents an approach that uses topological background knowledge to rewrite queries containing local expressions in a format better suited to standard search engines. To formalize local expressions, the Region Connection Calculus (RCC) is extended by additional relations, which are related to existing ones by means of composition rules. The approach is applied to web searches for communities in a part of Switzerland which are “close to” a reference place. Results show that query rewriting significantly improves recall of the searches. When dealing with approx. 30,000 role assertions, the time required to rewrite queries is in the range of a few seconds. Ways of dealing with a possible decrease of performance when operating on a larger knowledge base are discussed.".
