Study of information retrieval using fuzzy queries

With the expansion of the Internet, searching for information goes beyond the boundary of physical libraries. Millions of documents of various media types, such as text, image, video, audio, graphics, and animation, are available around the world and linked by the Internet. Queries are used to find information items relevant to an information need. Unfortunately, it is not always possible to get relevant information each time relative to one's query. To address this situation, many researchers have proposed the application of fuzzy logic for information retrieval. This paper reports the significance of this topic, some of the previous work in this area, current work, and a discussion on fuzzy information retrieval system where fuzzy logic is used to formulate imprecise queries against database tables.
