Coquery - a free corpus query tool
Coquery is a free corpus query tool for linguists, lexicographers,
translators, and anybody who wishes to search and analyse text corpora.
It is available for Windows, Linux, and Mac OS X computers.
You can either build your own corpus from a collection of text files (either
PDF, MS Word, OpenDocument, HTML, or plain text) in a directory on your
computer, or install a corpus module for one of the supported corpora (the
corpus data files are not provided by Coquery).
Tutorials and documentation can be found on the Coquery website:

Features
An incomplete list of the things you can do with Coquery:
Corpora
- Use the corpus manager to install one of the supported corpora
- Build your own corpus from PDF, HTML, .docx, .odt, or plain text files
- Filter your query for example by year, genre, or speaker gender
- Choose which corpus features will be included in your query results
- View every token that matches your query within its context
Queries
- Match tokens by orthography, phonetic transcription, lemma, or gloss, and restrict
your query by part-of-speech
- Use string functions e.g. to test if a token contains a letter sequence
- Use the same query syntax for all installed corpora
- Automate queries by reading them from an input file
- Save query results from speech corpora as Praat TextGrids
Analysis
- Summarize the query results as frequency tables or contingency tables
- Calculate entropies and relative frequencies
- Fetch collocations, and calculate association statistics like mutual
information scores or conditional probabilities
Visualizations
- Use bar charts, heat maps, or bubble charts to visualize frequency
distributions
- Illustrate diachronic changes by using time series plots
- Show the distribution of tokens within a corpus in a barcode or a beeswarm
plot
Databases
- Either connect to easy-to-use internal databases, or to powerful MySQL
servers
- Access large databases on a MySQL server over the network
- Create links between tables from different corpora, e.g. to provide
phonetic transcriptions for tokens in an unannotated corpus
Supported corpora
Coquery already has installers for the following linguistic corpora and
lexical databases:
If the list is missing a corpus that you want to see supported in Coquery,
you can either write your own corpus installer in Python using the installer
API, or you can contact the Coquery
maintainers and ask them for assistance.
