This is a very experimental resolution- and paramodulation-based automatic theorem prover Alabai, written in Java. The main purpose of the prototype is to serve as a guinea pig for experiments with new architectural ideas (see (see A. Riazanov, New Implementation Framework for Saturation-Based Reasoning, 2006, http://arxiv.org/pdf/0802.2127v1.pdf) and the Incremental Query Rewriting method for semantic querying of relational data (see A. Riazanov and M. A. T. Aragao, Incremental Query Rewriting, Canadian Semantic Web: Technologies and Applications, 2010, http://link.springer.com/chapter/10.1007%2F978-1-4419-7335-1_1 ). Project maintainer: Alexandre Riazanov, alexandre.riazanov@gmail.com Building -------- Use Maven 2 to build the prover (see ./pom.xml). The dependencies include, in particular, -- The logic-warehouse library: https://github.com/riazanov/logic-warehouse -- The cushion library: https://github.com/riazanov/cushion -- The tptp-parser library: https://github.com/riazanov/tptp-parser To build Alabai, download these libraries, extract the required commits (check the logs to find the appropriate library versions), and build and install them locally with Maven.
