Yoshikoder: The Basics

Created by Will Lowe at Harvard’s Department of
Government

Can provide a word count, custom dictionary word
count, and concordances (KWIC)

Available for free at www.yoshikoder.org

Some “standard” dictionaries also available at 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

also select a category).
Yoshikoder: Concordance
Yoshikoder: Concordance (also called KWIC)
Makes a concordance

matching the currently
selected pattern (can
also select a category).
Yoshikoder: Analysis
Types of analyses:
Document Word Frequencies: Shows frequencies for each word in the currently selected
document.
All Word Frequencies: Shows word frequencies for each document in the project.
Unified Word Frequencies: Shows word frequencies for all documents together. (all
documents need to be highlighted all at once)
Dictionary Report: Applies the dictionary to the current selected document.
Document Comparison: Applies the dictionary to two documents and compares the
results.
Statistical Comparison Report: Compares risk ratios for category proportion differences
in two documents.
