Opis

In these days our daily life is more and more affected by computers. For thisreason it is necessary to find a simple and intuitive way to interact with complextechnologies. Natural language dialog systems could be the solutionhow humans and machines could communicate with each other. One of themain tasks of such dialog systems is to provide fast and appropriate answersto users questions. The challenge is: how do we find these answers out ofthe flood of information? Is there a way or an algorithm to find the appropriateanswer to a given question?The author Christian Pretzsch gives, at first, an overview about thelinguistically and theoretically background. Therein, among other things, theconcepts: dialog, dialog systems, and ontology are introduced. Afterwards,answer selection and question-answering are elucidated, before the foundresults are tested for a concrete case study. This example and its evaluation isthe base for an alternative approach. The illustrated algorithm could be asolution to realize answer selection in a fast and effective way.This book is addressed to students and all interested parties of ComputationalLinguistics, Computer Science, and Applied Linguistics.
