Since our last update, we've reorganized the frontpage and revamped the contributors and citation policy. We've also added Latvian, Slovak, and Korean data!

We're pleased to announce a number of new languages in Wordbank, bringing us up above 20 languages. The new data are from ASL, Cypriot Greek, Kiswahili and Kirigama. We also have added British English short-form data from the Twins Early Development Study (TEDS). Take a look at these new additions!

We now have a FAQ!

Also, check out the semantic networks report and the new scoring tool.

Stay tuned for some new languages in the next few months.

We are pleased to announce that our paper on the wordbank site is in press at Journal of Child Language:

Frank, M. C., Braginsky, M., Yurovsky, D., Marchman, V. A. (in press). Wordbank: An open repository for developmental vocabulary data. Journal of Child Language. 

Our R package for accessing wordbank is now on CRAN! You can now install and use wordbankr even more easily.

We're pleased to announce that all derivatives from Wordbank – including downloaded data, tables, and graphs – are licensed CC-BY 4.0. To attribute derivatives, please cite:

Frank, M. C., Braginsky, M., Yurovsky, D., Marchman, V. A. (under revision). Wordbank: An open repository for developmental vocabulary data. Journal of Child Language.

Going forward, we will update the preferred citation for the site on the Publications page.

We are happy to announce that we have a new paper on Wordbank and the wordbankr package now under review. For now, this is the appropriate citation for the wordbank site:

Frank, M. C., Braginsky, M., Yurovsky, D., Marchman, V. A. (under review). Wordbank: An open repository for developmental vocabulary data.

We've been working on improving how you can access the Wordbank data from R, and the result is the wordbankr package. It's still a work in progress, so a lot of it may change, but using it you can now pull in data by-administration, by-item, and administration-by-item, with minimal hassle. Check out the package vignette for a tutorial!

We've just pushed an update to our analysis pages so that they include much more content. We not only have interactive visualizations (like the norms and items tools), we also have a number of non-interactive reports that we've put together on topics like gender differences, SES effects, etc. You can also see analyses from our CogSci paper this year on grammar-lexicon relationships. Let us know if you have comments (or analyses you'd like to add)!

We're excited to announce we've imported all of the CDI norming data from CLEX. Thank you to Rune Nørgaard Jørgensen! Wordbank now has almost 40,000 CDI administrations, across 10 different languages (Croatian, Danish, English, German, Italian, Norwegian, Russian, Spanish, Swedish, and Turkish).

Check out our new reports that let you explore our data, filter and sort it to suit your needs, and download it as a csv file. There's one report for by-administration data, with overall vocabulary sizes and demographic information, and one report for the full administration-by-item data. Also, all of the analysis reports now let you download the plot and the data being plotted!

We've spent the last few months overhauling Wordbank's data import to support adding in many datasets in different languages. Yesterday these updates went live, and Wordbank now has data in English, Spanish, Danish, and Norwegian, including both Words & Sentences and Words & Gestures. It's a total of almost 30,000 CDI administrations! Check out our reports to play around with all of these datasets, or look at this tutorial on accessing Wordbank from R if you're interested in running your own analyses.

This is the place where we will be announcing new features and datasets for the wordbank site (wordbank.stanford.edu). Stay tuned!
