Steps towards parsing of query sequences to a database / Proceedings of the First International Workshop on Expert Database Systems, October 1984
Abstract
Sequences of queries to a database system can have structure. Recognizing this structure is a kind of "parsing", analogous to the parsing of
sentences. We present two rather different approaches to recognition for exploitation. The first is a rule-based system that examines superficial
aspects of a query sequence to postulate preferences between sets mentioned in the queries. The second is a deeper, but more limited model
based on decision theory, which assigns utilities and suitability probabilities to individual set items, and attempts to explain set preferences on
that basis. Both these methods have disadvantages, and their performance is difficult to analyze because of the fuzzy nature of the application,
but it is hoped they can form the basis for more comprehensive man-machine interfaces.
