This repository contains the 2018 public-facing ACQDIV database that was used in our paper on frequent frames:

Moran, Steven, Damián E. Blasi, Robert Schikowski, Aylin C. Küntay, Barbara Pfeiler, Shanley Allen and Sabine Stoll. 2018. A universal cue for grammatical categories in the input to children: frequent frames. Cognition, 175, 131–140. DOI: https://doi.org/10.1016/j.cognition.2018.02.005.

Please find the latest public-facing ACQDIV database now archived in Zenodo: http://doi.org/10.5281/zenodo.3558641.

Below is the overview to the 2018 (deprecated) version.

This repository hosts the public-facing ACQDIV database. Currently, it includes longitudinal child language acquisition corpora in the ACQDIV database format for:

• Indonesian (Gil & Tadmor, 2007)
• Japanese MiiPro (Miyata & Nisisawa 2009, Nisisawa & Miyata 2009, Miyata & Nisisawa 2010, Nisisawa & Miyata 2010, Miyata 2012)
• Japanese Miyata (Miyata 2004a,b,c, 2012)
• Sesotho (Demuth 1992, 2015)

These corpora are available in various original input formats (e.g. CHAT, CHAT-XML) via the Child Language Data Exchange System (CHILDES) component of the TalkBank system and are made openly available under the Creative Commons license BY-NC-SA 3.0..

We have converted the original data formats into easily accessible tables and we have enriched the annotation data, in particular at the morpheme level. We also provide a linguistically-informed subset of grammatical classes for cross-linguistic research. For detailed information about the corpora and the data structures that we use, see the ACQDIV corpus manual.

The ground rules for using corpora from TalkBank and CHILDES are stipulated here and the use of individual corpora used in research should be cited accordingly:

The ACQDIV database also contains privately owned longitudinal child language acquisition corpora from languages that were selected from five clusters calculated via maximum diversity sampling (Stoll & Bickel, 2013) to achieve a typologically maximally diverse language sample:

• Chintang (Stoll et al. 2015)
• Cree (Brittain 2015)
• Inuktitut (Allen Unpublished)
• Russian (Stoll & Meyer 2008)
• Turkish (Küntay et al. Unpublished)
• Yucatec (Pfeiler Unpublished)

Access to these corpora is restricted by the project's Terms of Agreement. Contact Prof. Sabine Stoll for more information.

The research leading to these results has received funding from the European Unions Seventh Framework Programme (FP7/2007-2013) under grant agreement no. 615988 (PI Sabine Stoll).
