Global Syntactic Variation in Seven Languages: Toward a Computational Dialectology.

Area of Science:

• Computational sociolinguistics
• Linguistic variation
• Dialectometry

Background:

• Traditional dialectology faces limitations due to fixed variant sets and limited geographic scope.
• Previous studies often analyzed languages in isolation, hindering global comparative analysis.

Purpose of the Study:

• To develop a comprehensive global model of regional linguistic variation.
• To overcome constraints in dialectometry by employing novel computational methods.
• To analyze seven major languages (Arabic, English, French, German, Portuguese, Russian, Spanish) comparatively.

Main Methods:

• Utilized Computational Construction Grammar for a replicable set of syntactic features.
• Employed global language mapping using web-crawled and social media data.
• Developed models for seven languages using consistent methodologies.

Main Results:

• Computational Construction Grammar models significantly improved region-of-origin prediction compared to simpler syntactic features.
• The approach demonstrated robustness in identifying regional linguistic patterns across diverse languages.
• Global-scale experiments validated the effectiveness of the new methodology.

Conclusions:

• New computational sociolinguistics methods offer generalized models for understanding language variation and change.
• The study establishes a scalable framework for analyzing regional linguistic diversity worldwide.
• This research provides essential tools for future studies in dialectology and language evolution.
