IEEE Paper:
While semantic search technologies have been proven
to work well in specific domains, they still have to confront
two main challenges to scale up to the Web in its
entirety. In this work we address this issue with a novel
semantic search system that a) provides the user with the
capability to query Semantic Web information using
natural language, by means of an ontology-based Question
Answering (QA) system [14] and b) complements the
specific answers retrieved during the QA process with a
ranked list of documents from the Web [3]. Our results
show that ontology-based semantic search capabilities
can be used to complement and enhance keyword search
technologies.
