Semantic Web rules for business information

A description of the New Brunswick Business Knowledge Base (NBBizKB) is provided and is made available online in RuleML. NBBizKB realizes a two-step design. First, business facts are extracted, once from static CSV tables and, repeatedly from dynamic semi-structured HTML pages. Second, Semantic Web rules are developed to derive information implicit in the fact base. Fact extraction comprises an XML DTD design, CSV-to-XML conversion, HTML mining, and XSLT translations. Rule derivation employs the Java-based RuleML implementation of 00 jDREW to perform data validation, classification mapping, and information integration. Quantitative rule derivation results and findings about the original business data are reported. This rule-based reasoning over extracted facts about New Brunswick business comprises both a case study in business information mining and a use case for Semantic Web rules.
