Internet Access to Corpora: The AC/DC project


Em português

The AC/DC project stands for Acesso a corpora/Disponibilização de corpora ("acess and availability of corpora"), and is one of the activities of Linguateca, previously the Computational Processing of Portuguese project.

The physical address for this service, launched on 23 September 1999, is /ACDC/.

The underlying corpus management system is CWB (a new version of the IMS corpus workbench).

Main goals

One of the goals of Linguateca is to improve significantly the conditions for NLP of Portuguese, namely by

Corpora currently offered and their rough characterization

For each corpus, we present:

We provide more extensive documentation and information, in Portuguese, about the Corpora, the actual processing and encoding of the several kinds of information present in the corpora (tokenization, sentence separation and annotation).

Actual examples on how to invoke AC/DC can be found in exemplos (in Portuguese) and in a page with some old examples in English.

Also, extensive frequency lists are provided in the frequencies service, per corpus, and in total, and computed for both lemmata and forms, also per PoS. In that page, so far only in Portuguese, you are able both to download them or to search them using regular expressions.
