PERFORMANCE ANALYSIS OF KEYWORD SEARCH ENGINE

Abstract

In past years the researches on the keyword search engine have increased and now it has became an active area
for research in relational database and Information retrieval (IR). Till today so many this are been proposed and
implemented too but still there is missing of standardizations. Due to this lack of standardization there are different
evaluations and resultant information is present. In this survey the comparison of the already proven theories is done and
the performance evaluation of relational keyword search systems is also done with the help of various theories. After
comparing the various theories , memory consumption precludes many search techniques from scaling beyond small datasets
with tens of thousands of vertices. We also explore the relationship between execution time and factors varied in previous
evaluations; our analysis indicates that these factors have relatively little impact on performance. At last we have shown the
unacceptable performance of the systems and underscores the need for standardization which is implied by the community of
information retrieval system evaluating these retrieval system.
