of Government

Can provide a word count, custom dictionary word count, and concordances (KWIC)

website

Yoshikoder: Building Dictionaries Dictionaries contain categories and patterns

Categories are general terms that patterns fall under

Patterns are the words that are actually searched when performing a word count Wildcards are allowed

Employ* will search for “employ,” “employment,” “employed,” etc.

The name of the category must be included as a pattern if the user wishes for it be searched

Yoshikoder: Rationale Our purpose was to analyze news reports on

the Republican primary debate that occurred on 9/22/11 Transcript of the debate was compared with three

other news sources Cleveland Plain Dealer San Jose Mercury News CNN

Specific rationale was to compare the issues reported on by each outlet to all the issues presented at the actual debate
