Abstract

This document is the first version of the Corpus Encoding Standard (CES), which are a part of the EAGLES Guidelinesdeveloped by the Expert Advisory Group on Language Engineering Standards (EAGLES). The CES is designed to be optimally suited for use in language engineering research and applications, in order to serve as a widely accepted set of encoding standards for corpus-based work in natural language processing applications. The CES is an application of SGML (ISO 8879:1986, Information Processing--Text and Office Systems--Standard Generalized Markup Language) compliant with the specifications of the TEI Guidelines for Electronic Text Encoding and Interchange of the Text Encoding Initiative.

The CES specifies a minimal encoding level that corpora must achieve to be considered standardized in terms of descriptive representation (marking of structural and typographic information) as well as general architecture (so as to be maximally suited for use in a text database). It also provides encoding specifications for linguistic annotation, together with a data architecture for linguistic corpora.

The CES is being developed in a bottom up fashion, starting with minimal specifications and expanding based upon feedback resulting from its use, and the input of the research community in general. We invite and encourage all comments and discussion of any aspect of the CES.
