AST: New Tool for Logical Analysis of Sentences based on Transparent Intensional Logic

Logical analysis of natural language is able to extract semantic relations that follow the underlying logical formalism. Transparent Intensional Logic (TIL) has been designed to capture even high-order relations between sentence elements and systematically work with all kinds of language references, i.e. extensions, intensions and hyperintensions. In this paper, we introduce the first version of a new tool, called AST, for automatic semantic analysis of sentence. This tool is based on the TIL logic processing rules as they were implemented in the SYNT parser, in its logical analysis module. AST thus shares lexicons and semantic rules in the same format as in the SYNT parser, but allows to build upon the output of other syntactic parsers. AST is designed as a universal semantic analysis tool, which strictly separates the application logic and input data and strives for language independent analysis. Within the evaluation, we present preliminary results of testing AST on selected problematic phenomena, which were not correctly processed by the SYNT logical analysis.
