Fuzzy queries with weights based on fuzzy logic conjunctions
|
Abstract:
The previous work studied such queries as simple queries,compound queries,multi-relational queries,subqueries with weights and etc.Which solved fuzzy questions to some extent.But the logic connectives was always AND or OR,so the previous SQL queries had some limits.It didn't adapt to the natural language and did not satisfies the queries.Based on Zadeh's fuzzy theory,introduced fuzzy logic and weights to solve this kind of queries through the combinations of fuzzy theory and SQL functions,which would enrich fuzzy queries system,thus enabling more effective queries.
