The main problem on the Web is to locate information. Some reasons for this arise from the inefficiency of interfaces, incorrect information organization and data structure issues. A fuzzy approach to information retrieval systems can mitigate these problems. Advantages of fuzzy logic over sharp ones are the retrieval of information items which partial match the query and their ranking of impor...

The system accepts Boolean queries whose terms are weighted by means of the ordinal linguistic valu...
