CLEX: A Cross-linguistic lexical norms database

[Philip Dale]

Researchers and others interested in early vocabulary development may find
the newly elaborated CLEX website useful. The website
(http://www.cdi-clex.org <http://www.cdi-clex.org/> ) is a collaboration of
the CDI Advisory Board and the Center for Child Language, University of
Southern Denmark. It contains detailed lexical norms for all words included
in the MacArthur-Bates CDI for American English and adaptations of the CDI
into Mexican Spanish, Danish, Swedish, and Croatian. CLEX was inspired by
the collaborative success of the CHILDES system, and it is hoped that
additional language datasets will be incorporated into the system soon. The
website permits a range of query functions, both within and across
languages, including evaluation of user-defined subscales. More information
on the CLEX website is included in an article in the latest (March) issue of
the Journal of Child Language, ‘CLEX: A cross-linguistic lexical norms
database’, by Jørgensen, Dale, Bleses, and Fenson.

 

The abstract is included below:

Parent report has proven a valid and cost-effective means of evaluating

early child language. Norming datasets for these instruments, which

provide the basis for standardized comparisons of individual children

to a population, can also be used to derive norms for the acquisition

of individual words in production and comprehension and also early

gestures and symbolic actions. These lexical norms have a wide range of

uses in basic research, assessment and intervention. In addition,
crosslinguistic

comparisons of lexical development are greatly facilitated by

the availability of norms from diverse languages. This report describes

the development of CLEX, a new web-based cross-linguistic database

for lexical data from adaptations of the MacArthur-Bates Communicative

Development Inventories. CLEX provides tools for a range of

analyses within and across languages. It is designed to incorporate

additional language datasets easily, and to permit users to define

mappings between lexical items in pairs of languages for more specific

cross-linguistic comparisons.
