Web-based L2 Syntactic Complexity Analyzer - Single Mode
The single mode of the web-based L2 Syntactical Complexity Analyzer takes up to 2 samples of English text and generates both numeric and graphical results of any or all 14 indices covering (1) length of production units, (2) amounts of coordination, (3) amounts of subordination, and (4) phrasal sophistication and overall sentence complexity. Please note that each text should have a maximum of 1000 words. If you have multiple files to be analyzed, please use the Batch Mode.
