cplint is a suite of programs for reasoning with probabilistic logic programs. It contains programs for both inference and learning.
You can find the manual at https://github.com/friguzzi/cplint/blob/master/doc/manual.pdf or http://ds.ing.unife.it/~friguzzi/software/cplint-swi/manual.html
You can try it online at http://cplint.lamping.unife.it/
This is a SWI-Prolog (http://www.swi-prolog.org/) pack.
It can be installed with pack_install/1
$ swipl
?- pack_install(cplint).
The pack uses a foreign library and contains the library binaries for 32 and 64 bits Linux and 32 and 64 bits Windows. If you want to recompile the foreign library you can use
?- pack_rebuild(cplint).
On 32 and 64 bits Linux this should work out of the box. On 32 and 64 bits Windows the library must be rebuilt by hand.
First run pack_rebuild(cplint). This typically fails but produces the file
buildenv.sh in the root folder. You can modify this file looking at the
example files
buildenvmingw32.sh and buildenvmingw64.sh. Then you can run
$ source buildenv.sh
$ source configure
$ make install
It requires packs auc and matrix:
$ swipl
?- pack_install(auc).
?- pack_install(matrix).
$ cd <pack>/cplint/prolog/examples
$ swipl
?- [coin].
?- prob(heads(coin),P).
Other machine learning datasets are available in pack cplint_datasets (https://github.com/friguzzi/cplint_datasets)
