D-Level Analyzer is an automatic syntactic complexity analyzer based on the revised Developmental Level scale (Rosenberg & Abbeduto 1987; Covington et al. 2006). This analyzer assigns each sentence in an input text to one of eight developmental levels, depending on the structure of the sentence.
L2 Syntactic Complexity Analyzer
L2 Syntactic Complexity Analyzer (to be released soon) is a computational system designed to automate syntactic complexity analysis of written English language samples produced by advanced learners of English using fourteen different measures proposed in the second language development literature. The analyzer takes a written English language sample in plain text format as input and generates 14 indices of syntactic complexity of the sample.
