Frequently Asked Questions

Find Quick Answers

What is syntactic complexity analysis?

Syntactic complexity analysis measures the sophistication of sentence structures in written or spoken language, using metrics like T-units, clauses, and sentence length to assess language proficiency.

What file formats are supported?

Currently, only plain text (.txt) files are supported. The tool extracts and analyzes text content from uploaded files.

What linguistic metrics does this tool calculate?

The tool calculates: Mean Length of T-unit (MLT), Mean Length of Clause (MLC), Clauses per T-unit (C/T), Dependent Clauses per Clause (DC/C), Complex T-unit Ratio (CT/T), and Sentence Count.

Can I analyze multiple texts at once?

Currently, the tool analyzes one text at a time. For batch analysis, you would need to process texts individually or combine them into a single document.
