Syntagma Lexical Database

This paper discusses the structure of Syntagma's Lexical Database (focused on Italian). The basic database consists in four tables. Table Forms contains word inflections, used by the POS-tagger for the identification of input-words. Forms is related to Lemma. Table Lemma stores all kinds of grammatical features of words, word-level semantic data and restrictions. In the table Meanings meaning-related data are stored: definition, examples, domain, and semantic information. Table Valency contains the argument structure of each meaning, with syntactic and semantic features for each argument. The extended version of SLD contains the links to Syntagma's Semantic Net and to the WordNet synsets of other languages. The main resource of the Syntagma parser is its lexical database: the Syntagma Lexical Database (SLD). The current SLD addresses only Italian, but is related to Word Net's synsets. SLD has been generated through automatic procedures by a program, called Dictionary Scanner, which extracted and classified all kinds of lexical information coming from the source dictionary (given in htm format). 1.
