Keyword Extraction Based Summarization of Categorized Kannada Text Documents

The internet has caused a humongous growth in the number of documents available online. Summaries ofdocuments can help find the right information and are particularly effective when the document base isvery large. Keywords are closely associated to a document as they reflect the document's content and actas indices for a given document. In this work, we present a method to produce extractive summaries ofdocuments in the Kannada language, given number of sentences as limitation. The algorithm extracts keywords from pre-categorized Kannada documents collected from online resources. We use two featureselection techniques for obtaining features from documents, then we combine scores obtained by GSS(Galavotti, Sebastiani, Simi) coefficients and IDF (Inverse Document Frequency) methods along with TF(Term Frequency) for extracting key words and later use these for summarization based on rank of thesentence. In the current implementation, a document from a given category is selected from our databaseand depending on the number of sentences given by the user, a summary is generated.
