Abstract:A reference expert system may be considered to be a system with a knowledge base covering various aspects of the reference process in a library setting. Knowledge bases generally consist of several components (such as databases, rule bases, frames, and semantic nets) that interact with an inference engine, a user interface, and each other. This paper will examine progressively more complex knowledge-based systems for reference that can be constructed from components like these, concentrating at first on combinations of databases and rule bases. This examination will lead to a classification of reference expert systems. In Section 3, very simple architectures of a type common in other fields will first be considered. Arguments drawn from reference theory suggest that these simple architectures are appropriate primarily in dealing with directional reference transactions. In Sections 4 and 5, reference theory will be used to develop two additional architectures more appropriate to other reference transactions, such as ready-reference transactions. The classification of reference expert systems will be completed in Section 6 by examining further reference theory and then using it to develop variants on the three basic types. Section 7.1 will discuss briefly the use of reference knowledge bases for computer-assisted instruction. Section 7.2 will consider deep reference knowledge. The paper will conclude with some prognostications about future developments.
