Ferda New visual data mining environment Martin Ralbovský LISp-Miner Academic software project for research and teaching of knowledge discovery in databases at VŠE Uses association rule data mining, GUHA method Research and development since 1996, creation and implementation of new procedure 9 data mining procedures up-to-date Complex, but user-challenging tool Ferda Software project at MFF UK New user interface for LISp-Miner procedures Development since 2004 Created by: Michal Kováč, Tomáš Kuchař, Alexander Kuzmin, Martin Ralbovský Main goals of Ferda To simplify and clarify the process of data mining with the aid of visual programming Modularity, extensibility, distributibility Creation of a strong tool, features to take the LISp-Miner “one step further” Environment not only for association rules Working environment – box Box is an element of visual programming in Ferda Box contains sockets and properties In comparison to other DM systems, box is an abstraction of a function rather than a visual part of DM process User creates the task by connecting the boxes and setting their properties More perspectives on box – programmer sees programming language, logician sees formulas Parts of the environment Desktops More desktops for one project Property grid Standard component for setting properties Archive Storeroom for all the boxes in the project Docking Working with boxes Setting properties with property grid (possibly other modules) Modules for interaction Actions Boxes asking for creation Packing and unpacking of boxes Archive Contains all the boxes in a project Horizontal browsing along and against the connections Vertical browsing according to box categories Actions supporting desktop and archive synchronization Boxes expanding the system functionality Basic data types boxes each property is a hidden socket Group box joining everything to groups Dynamic and not-dynamic attributes when input data changes with time Equivalence class also over attribute Solving a practical task … Ferda – future Master theses of Ferda creators should add new functionality Generalization of task definitions with the aid of logic (EverMiner) Support for ontology Broadening of current procedures to relational equivalents
