Abstract: An information processing unit takes an input of raw data, this data is passed through various steps to generate useful information. Topic modeling is a process in which raw text corpus is passed onto a series of steps so that the document can be categorized into a set of topics.There are various methods for achieving topic modelling like Tf-Idf, LSI,LDA. These topics are then looked up onto global repository of linked information such as dbpedia. This paper explores ways to map local topics with global counterparts and retrieve useful information so as to develop intelligent systems capable of understanding semantics.
