Description
The Watermarking Corpora On-line System (WaCOS) is made up of a set of measures for the assessment of text corpora.
Funtionality
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.
Technology
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.
Technical Requirements
The end user is only required of an Internet browser in order to access the on-line system.
Modules
-
Innovation
A freely available web-based tool which may be used to study peculiarities of textual corpus features.
Development
Developed as part of David Pinto’s Ph.D. and the MiDES CICYT TIN2006-15265-C06-04 research project.
