06 Document Vector
Exercise: Creating and applying a document vectorIn this exercise you'll build a document vector and then apply it to a new document.1) Execute the Preprocessed documents metanode. It preprocesses the agendas of two instructor-led KNIMEcourses (L4-TP Introduction to Text Processing and L4-TS Introduction to Time Series Analysis). 2) Transform the preprocessed documents into a bag of words. 2) Calculate the document frequencies in the bag of words3) Filter the data by words that occur in both documents4) Transform the data into a document vector. Use Bitvector.5) Execute the Preprocessed new document metanode. This document contains the agenda text of the L4-BDIntroduction to Big Data with KNIME Analytics Platform course. 6) Transform the new document into a bag of words7) Apply the document vector model to the new document.
