Why join now?
This is not a request to endorse a finished resource. The SIG is still testing the research questions, annotation model, sense granularity, function taxonomy, validation procedures and technical workflow.
Contributors can therefore influence what is built, how it is tested and what evidence would be needed before any stronger CEFR-related claims could be considered.
Who could contribute?
Language experts
Review corpus examples and sense inventories in English, French, Spanish, German, Czech or future pilot languages.
Assessment and CEFR specialists
Advise on interpretation, claims, validation, taxonomy design and possible assessment applications.
Corpus and vocabulary researchers
Challenge the sampling, frequency, dispersion, register, lexical-sense and cross-language comparison methods.
NLP and technical contributors
Improve processing, prompting, reproducibility, quality assurance, data structures and reviewer tooling.
Teachers and materials specialists
Help test whether the proposed outputs would genuinely support curriculum, course and materials decisions.
Validation and review specialists
Develop human-review procedures, agreement studies, blind-validation samples and evidence standards.
Possible contribution areas
- Review or revise a language-specific sense inventory.
- Evaluate whether sentence examples have been assigned appropriate senses.
- Review the communicative-function taxonomy and its application.
- Test informed Pass 2 against blind annotation and human decisions.
- Advise on corpus balance, sampling, frequency and dispersion measures.
- Help align reviewed senses across languages without forcing English categories onto them.
- Develop use cases for teaching, assessment, research or policy.
- Improve scripts, documentation, interfaces or reproducibility.
What level of commitment is expected?
Participation can be small and focused. A contributor might review one lemma, test one part of the taxonomy, advise on one language, examine a validation sample or help improve a single script or page.
Coding experience is not required. Completing the form simply starts a conversation and does not commit you to a particular amount of work.
Express your interest
Complete the short form below with your name, email address, institution or organisation, relevant experience and any questions or queries you have. Your answers are submitted through Google Forms and are not posted publicly on GitHub.
For technical contributors
People who are comfortable using GitHub may also open a public issue to propose a code, documentation or workflow improvement.
