Available software
The DEMO system:
A generic system for automatic reasoning based on a logically
complete implementation of a proof predicate in Prolog.
Examples provided with the system:
abduction, induction, default logic, natural language analysis,
diagnosis, etc.
CHR grammars:
A grammar system based on Constraint Handling
Rules.
Applies constraint logic techniques for language processing in the shape
of a grammar notation on top of CHR. Features: A simple treatment of ambiguity;
abductive language interpretation without any extra machinery;
an implementation of Assumption Grammars; full integration with Prolog and CHR.
HYPROLOG:
A logic programming language with assumption and induction
Sudoku:
A little program in Prolog+CHR that solves Sudoku problems quickly.
Efficient viterbi
for PRISM models with annotations:
Extends the probabilistic-logic PRISM
system developed by Sato, Kameya and Zhou
with a facility to Viterbi predictions for models with annotations.
In PRISM this otherwise requires a lot of hand-coding to make it run efficiently;
here we do all that automatically.
