In addition, you can download crosstabs of word, POS and semantic tag frequencies with log-likelihood and dispersion statistics. These are tab delimited so can be opened in your favourite spreadsheet application.

As in previous elections, I will make local copies of manifestos available since they often disappear offline after the election. To prepare the text versions, I will use Adobe Reader to save as text and then manually edit (using TextWrangler) a small number of items such as headers, footers and page numbers to store them in pseudo-XML-style tags. In addition, I will follow the input format guidelines for CLAWS and convert n-dashes, pound signs, begin and end quotes to XML entities.
A note on word counts: Wmatrix counts semantically meaningful multiword expressions (MWEs) as one item, so other corpus software may well provide different counts here. These figures also depend on tokenisation in our NLP pipeline (by CLAWS).
Word frequency lists are tab delimited so you can load them in to your favourite spreadsheet program. MWEs are shown in the word frequency lists as words connected by underscore characters.
Key word and semantic tag clouds are produced by comparing the data with the BNC Written Sampler corpus. The larger the font, the higher the log-likelihood score, so larger items are more significantly overused compared to the reference corpus. See the Wmatrix main page and online tutorials if you want more details about how this works.
