Generating these document vectors from the text can be broken in two tasks. > 1. Create lucene index of the input plain-text documents > 2. From the index, generate the document vectors (sparse) with weights as TF-IDF values of the term. With lucene index, this value can be calculated very easily. > Presently, I have created two separate utilities, which could possibly be invoked from another class. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
