+Full semantic analysis of natural language (NL) texts is an open
+problem. The most comprehensive semantic systems build upon a mathematically
+sound formalism of a selected logical system. Mostly due to computability
+and efficiency, current systems work with the first order logic (or its variant).
+However, the low-order logic is not appropriate for capturing higher-order
+phenomena that occurs in natural language, such as belief attitudes, direct
+speech, or verb tenses. In our project, we develop new tool for automatic semantic analysis 
+(AST) that emerged from (a module of) the Czech syntactic parser [https://nlp.fi.muni.cz/trac/synt SYNT] .
+
+
+AST is now a standalone tool  based on Transparent Intensional Logic (TIL).
+It works with the same input files (lexicons, semantic rules, ...) that were designed and developed in SYNT. 
+
+AST can provide a semantic analysis in the form of Transparent Intensional Logic (TIL) constructions independently on the input syntactic parser and language. 
+
+Adaptation for new language consists in a specification of four lexicon files that describe lexical items, verb valencies, prepositional valencies and a semantic grammar.

+To create a semantic structure of a sentence, AST needs the output from
+previous analysis. A usual output is in the form of a syntactic tree [[Image()]]
