+********************************************************************************
+The file AmbiguousCorpusAMR.txt propose a corpus of ambiguous sentences in English, each with an AMR representation (in Penman notation) developed and validated by human annotators. 
+
+The corpus consists of fifteen statements that present lexical and syntactic ambiguities collected in several works of linguistics and grammar, with an average of 8 words per sentence. 
+
+The ambiguities of this corpus are of the following types:
+
+- Sentences with lexical categorial ambiguities
+
+- Sentences with lexical non-categorial ambiguities
+
+- Sentences with syntactical (structural) ambiguities
+
+The objective was to see if AMR parsers are able to deal with these kinds of ambiguities.
