Descripción

The Watermarking Corpora On-line System (WaCOS) is made up of a set of measures for the assessment of text corpora.

Funcionalidad

WaCOS allows linguistics and computational linguistics researchers to study the following corpus features: domain broadness, shortness, class imbalance, stylometry and structure. WaCOS provides a friendly interface in order to easily evaluate corpora.

Tecnología

WaCOS front-end has been programmed with PHP. It integrates a set of modules written in different programming languages (C, C++, Java, AWK). Among the several components of this system, it uses n-gram language modelling, Zipf distribution of frequencies, density-based measures, internal clustering validity measures, etc in order to assess the relative hardness of a given corpus.

Requisitos técnicos

The end user is only required of an Internet browser in order to access the on-line system.

Módulos
