Developing an ontological FAQ system with FAQ processing and ranking techniques for ubiquitous services

This paper proposed an ontological FAQ system on the personal computer domain, which employs ontology as the key technique to pre-process FAQs and process user query in ubiquitous information environments. It is also equipped with an enhanced ranking technique to present retrieved, query-relevant results. Basically, the system bases on the wrapper technique to help clean, retrieve, and transform FAQ information collected from a heterogeneous environment and stores it in an ontological database. Our experiments show the system does improve precision rate and produces better ranking results.
