PISA is a famous town in Italy, because of the Leaning Tower. But it is also the name for my graduation project I did in Chennai, India. PISA stands for PHP Intelligent Search Application.
Abstract
This paper describes an idea, how result lists of search engines could be improved and adapted to user profiles automatically. To achieve this goal, two different algorithms have been implemented. One is a probabilistic method of classification known as Bayesian algorithm and the other is TF-IDF (Term Frequency – Inverse Document Frequency), frequently used in information retrieval systems. Along with a detailed description of the objects in PISA, the test results of different conditions and algorithms are compared and summarised. In addition, needed fundamentals of network protocols, database access, and scripting languages are introduced and explained.
