Open Source Haskell Artificial Intelligence Software

Duckling is a Haskell library developed by Facebook for parsing and normalizing natural language expressions into structured data. It supports a wide range of entities such as dates, times, durations, distances, temperatures, numbers, and currencies. Designed for use in conversational agents, chatbots, and natural language processing applications, Duckling converts fuzzy user input into a consistent and machine-readable format. It features multi-language support and is widely used in production environments requiring robust entity extraction.

HLearn is a Haskell-based machine learning library focused on composability, algebraic structure, and performance. It provides a functional approach to building machine learning algorithms by leveraging algebraic properties such as monoids and groups. This allows for parallel, incremental, and distributed computation in a mathematically consistent way. HLearn aims to provide implementations of common algorithms like k-means, naive Bayes, and others while maintaining the expressiveness and safety of the Haskell language.

Hpylos is an AI of Pylos, a board strategy game for two players. Written in Haskell, uses OpenGL and provides with couple algorithms. User interface allows playing a game against computer, observing two algorithms playing or two humans play.

Foo (abbreviation from football) is a playing machine of Paper Soccer, a pencil and paper game for two players, described in WIKIPEDIA. Written in Haskell, contains also simply interface using HOpenGL library. Provides bunch of playing algorithms.

BuddyScout is an interface between BuDDy (Binary Decision Diagram library) and GHC (Glasgow Haskell Compiler). It enables you to use the BDD library from within Haskell programs.

Dickinson is a text-generation language. You can try out the language on the web without installing anything. Binaries for some platforms are available on the releases page. There is an install script that will try to download the right release for your computer.

Procreator is a framework for genetic programming written in Haskell. Procreator generates fully typed programs. This will allow for more effective crossover and for better compilation of the generated programs.

A Haskell implementation of the Three Man morris game together with an AI for playing against the Computer. Command line based, needs Haskell interpreter.

A beginners' level theorem prover project for logic students. Okitsune is written in Haskell and open for contributions.

Proof Logic is a functional and equational logical framework for theorem proving based on Combinatory Logic and Lambda Calculus, whose expressions are both terms and proofs proving the equality between two terms.
