Corpora developed by linguists to study languages are a promising source of authentic materials to employ in the development of OER for language learning. Recently, COERLL’s SpinTX Corpus-to-Classroom project launched a new open resource that seeks to make it easy to search and adapt materials from a video corpus.

The SpinTX video archive  provides a pedagogically-friendly web interface to search hundreds of videos from the Spanish in Texas Corpus. Each of the videos is accompanied by synchronized closed captions and a transcript that has been annotated with thematic, grammatical, functional and metalinguistic information. Educators using the site can also tag videos for features that match their interests, and share favorite videos in playlists.

A collaboration among educators, professional linguists, and technologists, the SpinTX project leverages different aspects of the “openness” movement including open research, open data, open source software, and open education. It is our hope that by opening up this corpus, and by sharing the strategies and tools we used to develop it, others may be able to replicate and build on our work in other contexts.

So, how do we make a corpus open and beneficial across communities? Here are 5 ways:

Minimize barriers to your content. Searching the SpinTX video archive requires no registration, passwords or fees. To maximize accessibility, think about your audience’s context and needs. The SpinTX video archive offers a corpus interface specifically for educators, and plans to to create a different interface for researchers.

Add a Creative Commons license to your corpus materials. The SpinTX video archive uses a CC BY-NC-SA license that requires attribution but allows others to reuse the materials different contexts.

Allow others to easily embed or download your content and data. The SpinTX video archive provides social sharing buttons for each video, as well as providing access to the source data (tagged transcripts) through Google Fusion Tables.

When possible, use and build upon open source tools. The SpinTX project was developed using a combination of open source software (e.g. TreeTagger, Drupal) and open APIs (e.g. YouTube Captioning API). Custom code developed for the project is openly shared through a GitHub repository.

Make it easy for others to replicate and build on your work. The SpinTX team is publishing its research protocols, development processes and methodologies, and other project documentation on the SpinTX Corpus-to-Classroom blog.

Openly sharing language corpora may have wide-ranging benefits for diverse communities of researchers, educators, language learners, and the public interest. The SpinTX team is interested in starting a conversation across these communities. Have you ever used a corpus before? What did you use it for? If you have never used a corpus, how do you find and use authentic videos in the classroom?  How can we make video corpora more accessible and useful for teachers and learners?
