TAASSC: Tool for the Automatic analysis of Syntactic Sophistication and Complexity

Picture
TAASSC is an advanced syntactic analysis tool. It measures a number of indices related to syntactic development. Included are classic indices of syntactic complexity (e.g., mean length of T-unit) and fine-grained indices of phrasal (e.g., number of adjectives per noun phrase) and clausal (e.g., number of adverbials per clause) complexity. Also included are indices that are grounded in usage-based perspectives to language acquisition that rely on frequency profiles of verb argument constructions.

TAASSC is easy to use. It takes plain text files as input (it will process all plain text files in a particular folder) and produces a comma separated values (.csv) spreadsheet that is easily read by any spreadsheet software.
