Extracting semantic information from multiple natural language sources and combining that information into a single unified resource is an important and fundamental goal for natural language processing. Large scale resources of this kind can be useful for a wide variety of tasks including question answering, word sense disambiguation and knowledge discovery. A single resource representing the information in multiple documents can provide significantly more semantic information than is available from the documents considered independently. In this talk I will describe the ASK Net system, which extracts semantic information from a large number of English texts, and combines that information into a large scale semantic network using spreading activation based techniques. I will discuss how the networks are created and integrated, and also touch on the topics of evaluation and some potential future uses for the ASK Net system.
