Welcome to the Bayesian Network Toolkit Home Page

Project Specification The aim of this project is briefly to: Produce a toolkit enabling the display and manipulation of Bayesian Networks. Utilise the new .BIF standard for representing networks in XML Act as a foundation and stimulus for further research into practical extensions of Bayesian Network utilities. A software toolkit is required to maintain, build and analyse the agreed Bayesian Interchange file format. The software would comprise the following components: Core: To produce a utility to parse the .BIF file format and to calculate the probability matrices and propagation's contained within its structure. Building on from the above, the project will take on the following directions: Direction 1: To produce a graphical tool for the construction and manipulation of .bif files Direction 2: To enable networks to be constructed from data. Direction 3: To generate data conforming to a given network. Each direction will be tied together with the core component and other directions to produce a general toolkit. The project is not be restricted to the above scope and incorporates research into the algorithms required for direction 2 and for optimising generated data sets.
