Speeding Up Multilingual Grammar Development by Exploiting Linked Data to Generate Pre-terminal Rules

Abstract

The development of grammars, e.g. for spoken dialog systems, is a time- and effort-intensive process. Especially the crafting of rules that list all relevant instances of a non-terminal, e.g. Greek cities or Automobile companies, possibly in multiple languages, is costly. In order to automatize and speed up the generation of multilingual terminal lists, we present a tool that uses linked data sources such as DBpedia in order to retrieve all entities that satisfy a relevant semantic restriction. We briefly describe the architecture of the system and explain how it can be used by means of an online web service.
