Combining linguistic and knowledge-based engineering for information retrieval and information extraction

چکیده
Controlled-term indexing (the method of choice for multimedia collections and still very popular for purely textual material), appears an expensive solution because it takes huge resources and manual indexing. It is not possible, however, to perform a well-founded asessment of various approaches to information retrieval. We discuss ways to improve controlled-term indexing and illustrate these by looking at the Condorcet project carried out at Twente by us and co-workers. We round off with a discussion that, we hope, will raise more questions than it answers.

Traditional methods of multi-word term extraction have used hybrid methods combining linguistic and statistical information. The linguistic part of these applications is often underexploited and consists of very shallow knowledge in the form of a simple syntactic lter. In most cases no interpretation of terms is undertaken and recognition does not involve distinguishing between diierent senses ...

This strategy, which is called underspecification, was implemented in a Natural Language Engine (NLE) for automatic information extraction, called ELSA (an acronym for English Language Semantic Analyser), which was developed at the Department of Language & S...
