Constructional Complexity Analyzer
Project Description
The Constructional Complexity Analyzer (CCA) is a tool designed to measure the constructional diversity, constructional elaboration, and verbal diversity of English texts.
Features
CCA outputs various scores for the following indices:
1. Constructional Diversity
Calculates the following diversity measures based on constructions:
- Root TTR (RTTR; Guiraud, 1960)
- Herdan’s C (or log TTR; Chotlos, 1944; Herdan, 1960)
- Maas’ score (Maas, 1972)
- Moving-average type-token ratio (MATTR; Covington & McFall, 2010)
- Hypergeometric distribution diversity index (HD-D; McCarthy & Jarvis, 2007)
- Measure of textual lexical diversity (MTLD-Original; McCarthy, 2005; McCarthy & Jarvis, 2010)
- Moving-average bidirectional measure of textual lexical diversity (MTLD-MA-BI; McCarthy & Jarvis, 2010)
- Moving-average wrapped measure of textual lexical diversity (MT
2. Constructional Elaboration
Calculates the mean number of dependents (except punctuation marks) for individual constructions
3. Verb Inventory Size
Calculates log 10 [type frequency of verbs + 1 ] for individual constructions
