Keyword is the important item in a document that provides efficient access to the content of a document.In the Existing system, Synonym, Homonym, Hyponymy and Polysemy problems were solved from only trained extracted keywords in the meeting transcripts.Synonym problem means different words which have similar meaning they are grouped and single keyword is extracted.Hyponymy problem means one word denoting subclass that is considered and super class keyword is extracted.Homonym means a word which can have two or more different meanings..A Polysemy means word with different, but related senses.Hidden topics from meeting transcripts can be found using LDA model.MaxEnt classifier is used for extracting keywords and topics which will be used for information retrieval Training the keyword from the dataset is separately needed for all the problems, it is not an automatic one .In this proposed frame work, a dataset has been designed to solve the above mentioned four problems automatically.
