Meta Information for Knowledge Navigation and Retrieval: What’s in There?

David Steier, Scott B. Huffman and Walter C. Hamscher

There has been little reported in the literature on exactly what meta-information is important for describing real-world task contexts. We present our preliminary findings on this subject in this paper. Our goal is to create a "content theory" on which to base languages and support tools for the delivery of knowledge services, in contrast to focusing more narrowly on answering queries in isolation. We define a knowledge service as the provision of content in some form and at some level of quality, subject to constraints on the resources needed to perform the service. This paper begins with some conceptual preliminaries, and then discuss these four elements in more detail. As illustrative examples of the use of meta-information, the paper describes two knowledge services: monitoring management changes, and search for potential conflicts of interest in prospective litigation support clients.
