Legal Document Search Engine

Abstract

Legal Document Search Engine is a web based application that enables user to search legal documents. Legal documents include court decisions, constitution and legislation. User will provide a query and against that a query a list of ranked documents will be displayed to the user. Two different ranked retrieval models are used to develop this search engine that are: tf-IDF and BM25. After implementing both ranked retrieval models the system is evaluated against a query set. Both models are evaluated against a same query set and then result are compared in order to find the best ranked retrieval model for this system. For persuasion of the user a dynamic word cloud has been made which is regenerated in response to every query along with auto-correction and suggestions for the given words.
