The Mobile is a circuit that  receives and sends signals through earth stations and satellites so the objective of this research is to build a system that retrieves information about  the location of the  mobile user .
The proposed system gets information of the location of the mobile user within Mosul university depending on the values of longitude and Latitude that have  been received from GPS .
The system displays on the mobile screen the values of longitude and latitude of the current location, as well as a list of names for the nearest buildings that surrounding the user location .
The system works on a mobile model (Nokia) from the third generation and beyond. This mobile has an integrated GPS receiver. The job of this receiver is to receive the incoming signals from the satellites, and they are  working out of the buildings (out door). We used the Java 2 Micro Edition   (J2ME) Language to write the program for this application, since it is the language that is mostly used to write the mobile applications.

This research is one of the important steps towards processing the most significant challenge in digital libraries and web, which is computing document’s rank, its importance, and its relevance to the user information need. This is achieved through the utilization of fuzzy logic high potential capabilities in dealing with such sort of problems and providing notable flexibility for the user to get his favorite subjects.
The research is concerned with designing and implementing a proposed information retrieval system, called FIRS (Fuzzy Information Retrieval System). This system is developed to deal with huge database, which contains different text file types and sizes. This database is distributed over a collection of server computers, connected with the intranet network that is dedicated for this system.
The system has the ability for mining of data available in this database and retrieving the useful information that corresponds with the user need. This is accomplished through applying the proposed algorithms for indexing process, document’s rank computations, generating keywords process, and finally, displaying information retrieval results. The proposed system gives high quality results comparing with other information retrieving algorithms.
