DyALog is an open source project developped by INRIA Alpage team (formerly ATOLL).

This project is part of Project Alpage which aims to develop tools and techniques in order to access, process and use documents in natural language. You can find our demos on this page.

Projects which are part of Alpage are the following: Alexina, ALPAGE Linguistic Workbench, DyALog, MetaGrammar Toolkit and SYNTAX.

DyALog is an environment to compile and run logic programs and natural language tabular parsers for various grammatical formalisms (DCGs, TAGs, TIGs, RCGs).

Demo: Some parsers built with DyALog may be tried on line, including a large coverage hybrid TIG/TAG French grammar derived from a metagrammar.
