CDS_EP was based on a section of the Child Directed Speech materials included in the FrePoP database: http://frepop.letras.ulisboa.pt (see About > The input of FrePoP: List of corpora)

This child directed speech resource was built as part of the supporting documents for the McArthur Bates Communicative Inventories (CDI) for European Portuguese - Short forms. The main goal behind CDS_EP was to provide information of the child input relevant to the development course of lexical acquisition. Lexical frequency lists (word forms, not lemmatized) were obtained with the FreP tool (Martins, F., M. Vigário & S. Frota. 2011. FreP - Frequency in Portuguese. Version 3.0.).

CDS_EP contains frequency lists for the following age ranges (organizes alphabetically and by frequency rank):

CDS_0-18 (types: 2714; tokens: 48746)

CDS_16-30 (types: 5951; tokens: 201871)

CDS_31-36 (types: 2009; tokens: 23078)

CDS_37-40 (types: 1558; tokens: 12923)

CDS_0-40 (types: 7634; tokens: 286618)

CDS_EP comprises data from eigth caregiver-child dyads.
