CasualConc is a concordance program that runs natively on Mac OS X 10.5 Leopard or later (the beta version is for 10.7 or later). It was originally designed for casual use (preliminary analysis or non-research purposes), though I've been using it for my own research (and may others have). It can generate kwic concordance lines, word clusters, collocation analysis, and word count. This program is only tested with English text just because that is the only language I can understand other than Japanese (though I heard from some people that CasualConc works ok with other European languages, such as Greek, Italian, etc.). If you use CasualConc with languages other than English, let me know how it works.
If you prefer to read in Japanese, 日本語サイトもあります。
ATTENTION: If you updated R to 3.3, you need to uncheck/check Use R for Visualization to re-install necessary packages. If you have problem with Visualization tools after you updated R to 3.3, you might need to re-install some packages.
Current Version: 2.0.5 (for OS X 10.9 or later) - last updated on 2016/05/29
System requirement: Mac with Mac OS X 10.9 or later with plenty of memory.
For more information about recent changes, check What's New.
This new version (2.0) has visualization functions using the statistical environment R (needs to be installed separately).
The following samples are created entirely on CasualConc 2.0 (with R in the background).
Old Version for Snow Leopard: 1.9.7 (for OS X 10.6.8 - 10.9) - last updated on 2014/12/05
System requirement (Old Beta): Mac with Mac OS X 10.6.8 or later with plenty of memory.
NOTE: If you use Lion or Mountain Lion, try beta and follow the instruction on the download page.
File format: works best with plain text files (.txt) encoded in ASCII or UTF-8, but can handle other file types and other encodings (see Preferences - Files). Reading non-plain text files will take more time to process. PDF files should be text-embedded. You can create database files from these file types except for PDFs for faster search. Check How to Use for more information.
Supported languages: any single-byte character language separated by single-byte space. Double-byte character language (East Asian languages) is also supported now, but you need to specify the language setting in Preferences to use with Japanese (or other East Asian Languages).
Mac users who don't want to start up Windows machine, switch to
BootCamp, or run Virtual PC/Parallels/VM Ware for simple concordancing
for preliminary analysis, preparing teaching materials, learning, etc.
(CasualConc is probably not good enough as your primary research tool)
If you use CasualConc, please send me any feedback, bug report, or feature request. Any comment will motivate me to improve CasualConc. Please email me at casualconc (at) gmail.com. (replace (at) with @).
By the way, CasualConc is freeware, but if you think it is useful, buy me coffee or good chocolate if we ever meet : ).
Currently, 7 other language-related applications are also on this site. They require Mac OS X 10.6 Snow Leopard (some require 10.7 Lion) and are also freeware.
CasualPConc - a simple parallel concordancer
CasualMultiPConc - a more basic parallel concordancer, but can handle parallel corpora up to 5.
CasualTagger - a tagging helper (?) application to assist tagging your corpus (includes English POS tagging with EngTagger or rbtagger); batch processing available.
CasualTextractor - a kind of file converter, extracting text information from Word/PDF/HTML etc files and save as plain text files. This also converts text encodings of plain text files.
CasualTranscriber - a transcription helper to assist transcribing video/audio files
CasualMecab - a Japanese POS/morphological analyzer using Mecab (MeCab and MeCab-Ruby need to be installed separately); batch processing available.
CasualTreeTagger - a GUI front end of TreeTagger.
IPATypist - a helper application to type IPA characters.
