4 Comparing Documents Data mining: the search for knowledge in large amounts of data. Data: digital documents found on crime scene or fabricated by police describing the crime scene Knowledge: what crime labs may be setup by the same group of criminals Data mining tools: Text mining: extraction of entities from documents Distance measure on extracted output: document similarity Visualization: clustering of documents on screen 2/26/2019 T.K.
