Overview
On August 27, 2012, Gavin Matthews and Gerard Burnand of NTENT presented the following white paper to the Lotico San Diego Semantic Web group.
Abstract
NTENT maintains and develops the Excalibur semantic web search engine, a long-standing project inherited from Convera Technologies, and the Editorial Related Advertising system, inherited from FirstLight ERA. Together these use semantic and linguistic processing of web pages to provide vertical search portals and context-sensitive advert placement. Behind the scenes, Excalibur relies on a large scale WordNet-style general ontology, extended for the various verticals that are supported. This is used to latch and disambiguate concepts within unstructured natural language text. The semi-structuring provided by RDF embedding is also used to derive additional information.
