Over the past years, multitudinous techniques have come into existence which performs the automatic summarization such as term frequency, inverse document frequency, sentence position, sentence length, LSA and many more. In this paper, we compare these techniques and conclude which technique executes best. Keywords: inverse document frequency, LSA, term frequency, text summarization;
