Evaluating Performance of Keyword Search Systems

In back few years many system have been proposed. But the problem with them is that most of the system are defective or they do not give the exact search results. In this paper we are measuring the performance of all the search systems, doing this will help to choose the correct search system. The analysis of system that already exist will be done. In this paper we will also seek the relationship between time needed for execution and factors changed in previous performances. The analysis shows that previous factors have less influence on performance. The results here indicate that many systems that are existing do not give the satisfactory or needed performance for realistic retrieval tasks. There is need of standardization.
