The Yoshikoder is a cross-platform multilingual content analysis program developed as part of the Identity Project at Harvard’s Weatherhead Center for International Affairs.

You can load documents, construct and apply content analysis dictionaries, examine keywords-in-context, and perform basic content analyses, in any language.

The Yoshikoder works with text documents, whether in plain ASCII, Unicode (e.g. UTF-8), or national encodings (e.g. Big5 Chinese.) You can construct, view, and save keywords-in-context. You can write content analysis dictionaries. Yoshikoder provides summaries of documents, either as word frequency tables or according to a content analysis dictionary. You can also apply a dictionary analysis to the results of a concordance, which provides a flexible way to study local word contexts. Yoshikoder’s native file format is XML, so dictionaries and keyword-in-context files are non-proprietary and human readable.

TLA-team: This free program (GPL) comes with a clean interface and is easy to use. Documents to analyse must be plain text files. The number of features is limited: for example only a simple * wildcard is supported for patterns, no regular expressions. Dictionaries and conconrdances can be exported to clean HTML, concordances also to Microsoft Excel spreadsheets. As of 2012 this program was last updated in 2006 (but still works).
