L2 Syntactical Complexity Analyzer (L2SCA) developed by

computational tool which produces syntactic complexity indices of written English language texts.[1] Along with Coh-Metrix, the L2SCA is one of the most extensively used computational tool to compute indices of second language writing development. The L2SCA is also widely utilised in the field of corpus linguistics.[2] The L2SCA is available in a single and a batch mode. The first provides the possibility of analyzing a single written text for 14 syntactic complexity indices.[3]
The latter allows the user to analyze 30 written texts simultaneously.

Usage

Second language writing development

The L2SCA has been used in numerous studies in the field of second language writing development to compute indices of syntactic complexity.[4][5][6]

Corpus linguistics

The L2SCA has also been used in various studies in the field of corpus linguistics.[7][8]
