By Madeleine Bates (editor), Ralph M. Weischedel (editor)

Even though ordinary language processing has come a ways long ago 20 years, the expertise has now not accomplished an important influence on society. is that this due to a few basic quandary that can not be triumph over? Or simply because there has no longer been sufficient time to refine and observe theoretical paintings already performed? Editors Madeleine Bates and Ralph Weischedel think it truly is neither; they consider that numerous serious matters have by no means been competently addressed in both theoretical or utilized paintings, they usually have invited able researchers within the box to do this in demanding situations in ordinary Language Processing.

32 M. Bates, R. J. Bobrow, and R. M. Weischedel Measurement of NL systems requires three distinct types of comparisons: 1. Longitudinal: It is critical to be able to measure the performance of a system over time, so that progress can be tracked. 2. Cross-System: It should be possible to compare the overall performance of two systems in explicit terms. This focus on whole-system performance will help localize the strengths and weaknesses of complete systems and will identify topics for research and development efforts.

3. 4. 5. Words unknown to the hearer or reader, but part of the language. Novel or unknown word senses, although the word itself is known. For instance, Navy jargon includes phrases such as What is Stark's readiness? Although that sublanguage does not include preparedness as a synonym for readiness, it would be useful for a system to be able to infer what a user means by the input What is Stark's preparedness? , metaphor, metonymy, and synecdoche.
