Abstract
In this paper, imprecise information is represented by fuzzy disjuncti ve information, and an extended fuzzy relational model is used to acco mmodate such information. In the presence of imprecise information, an swers to a query can be categorized into two kinds of answers: sure an swers and possible answers. To find more likely answers to a given que ry, we develop a method to measure the matching strength of each tuple as an answer to the query. The quality of an answer is higher in the case where less extra information is required and the more sure inform ation is provided.
