approach has been complemented by using explicit knowledge
already available in metadata records, e.g. the name
of a journal. The resulting classification process is a combination
of rule based and statistical methods.
Another aim of the project is to improve the user satisfaction
especially by avoiding empty result sets. Several
complementing approach are currently under evaluation.
Linguistic processing can be used to not only correct the
spelling of terms, but also identify the language, as well as
provide an automatic thesaurus-based translation of domain
specific terms into other languages. Semantic technologies
complement the linguistic processing by automatically
enhancing the query with related terms in case the
result is too small or empty.
Potential Applications & Future issues
By the end of the project, FIZ Technik and TIB Hannover
will be able to index new documents much more efficiently
and with a higher quality than is possible today. This will
strengthen their position in the global information market,
since with less overhead, their customers will ultimately
have higher quality and recent information. Moreover,
since the results are of a generic nature, they are usable
by publishers or for company’s internal information management
as well.
