Document similarity visualization

In the present work we study visual comparision of texts, especially by nding similarity in text documents by dotplot technique. An algorithm for this type of comparison was implemented and graphic user interface was made to allow user to work interactively. Also, command-line version of the application was created to allow batch processing of multiple documents. Instructions to use these programs are written in user documentation whichis added to this work in Appendix A. Further we study which patterns could grow up in dotplot and what these patterns predicate about documents. It is possible to nd self-similarity in one documents or similarity in two di fferent documents
