UCREL Corpus Research Seminar - Lab Session

Wmatrix corpus analysis and comparison tool: a practical hands-on tutorial

Paul Rayson (Lancaster University)

Wmatrix is a web-based tool for English corpus analysis that combines techniques from corpus linguistics and natural language processing. Users can load their own corpus data, make frequency lists, generate key words, run concordances and calculate collocations via a web-browser interface. In addition, the corpus data is automatically tagged for part-of-speech and semantic fields. These two extra levels of annotation can then be used to generate tag frequency lists, tag concordances and collocations of tags and to apply the log-likelihood keyness statistic to the tag level. This two-hour session will take place in the Faraday A205 lab 2-4pm and will guide new and existing users through the online tutorials. More details of research undertaken using Wmatrix can be seen at along with an irregular series of podcast videos describing the tool. It has been one year since the launch of Wmatrix version 3 running on a new faster and larger capacity server in the Lancaster University cloud computing infrastructure. Participants are encouraged to bring their own English corpus data to experiment with the software.
