Abstract

This paper describes inductive inference for synthesizing context free grammars from positive and negative sample strings, implemented in Synapse system. For effective inference of grammars, Synapse employs the following mechanisms.

  1. 1.

    A rule generating method called “inductive CYK algorithm,” which generates minimum production rules required for parsing positive samples.

  2. 2.

    Incremental learning for adding newly generated rules to previously obtained rules.

Synapse can synthesize both ambiguous grammars and unambiguous grammars. Experimental results show recent improvement of Synapse system to synthesize context free grammars.
