TXM is free, open-source Unicode, XML & TEI compatible text/corpus analysis environment and graphical client based on CQP and R. It is available for Microsoft Windows, Linux, Mac OS X and as a J2EE web portal.


  • Provides qualitative analysis tools:
    • kwic concordances of word patterns based on the efficient CQP full text search engine and its powerfull CQL query language
    • word pattern frequency lists based on any word property (graphical form or type, lemma, pos...)
    • word pattern progression graphics
    • Examples of word patterns, expressed in the CQL query language which is based on word & structural level properties:
      • "aiming" to simply search for the word 'aiming'
      • ".*ing" to search for words ending in "ing" (including mainly verb forms)
      • [pos="VERB" & word=".*ing"] to search for verb forms ending in ".ing" (where Part of Speech annotation is present)
      • [lemma="group"] []{0,3} [pos="VERB" & word=".*ing"] to search for the collocation <group lemma> followed by a <verb with progressive aspect> with at most 3 words in between
    • rich HTML-based text edition navigation with links from all other tools
  • Provides quantitative analysis tools, based on R packages:
    • factorial correspondance analysis
    • cluster analysis
    • specific word patterns analysis
    • collocations analysis
  • Helps to build various corpus configurations: sub-corpora or partitions (for contrastive analysis between text structures or word selections)
  • Large spectrum of input formats
    • several text formats (from raw to rich):
      • Unicode TXT
      • ODT
      • XML
      • XML/w (where some or all word limits and properties can be pre-encoded)
      • XML-TEI P4 (according to Perseus project practice)
      • XML-TEI P5 (according to various projects practice: BFM, BVH, NLTK, etc.)
    • speech transcription: XML-TRS (from Transcriber software, with time synchro)
    • aligned corpora: XML-TMX (with texts in relation of translation or versioning)
    • news portal articles: XML-PPS (Factiva), Europresse
    • etc.
  • Applies various NLP tools on the fly on texts before analysis (e.g. TreeTagger for lemmatization and pos tagging)
  • Indexes words and their properties as well as hierarchical structure of texts
  • Indexes external or internal text metadata or speaker metadata
  • Exports any result in CSV, XML or SVG format
  • Provides Scripting facilities for repetitive or lengthy tasks automation or for platform extension (in Groovy/Java dynamic language)
  • Includes a complete text editor to edit data sources, results and scripts
  • Runs as standalone application for Windows, Mac OS X or Linux
  • Runs also as web portal to give corpora access and analysis online through any web browser (including account and access control management)
  • Open source licence: based on the best open source components for text analysis: CQP, R and Java & XSLT libraries
  • Modular architecture (Eclipse RCP OSGi and J2EE conformant): one toolbox connecting all core components to build the applications
  • Efficient Eclipse or Netbeans powered development framework

System requirements

The standalone version runs on:

  • Windows - 32bit or 64bit (tested on XP, Vista and 7)
  • Mac OS X (tested on 10.5, 10.6 and 10.7)
  • Linux - 32bit or 64bit (tested on Ubuntu and Debian)

The portal server runs on any J2EE capable platform (tested in Tomcat and Glassfish).

Source code and licensing

Open Source under GPL V3 licence.

Support for TEI

Supports TEI and TEI Lite "out of the box" at the XML level: words will be tokenized inside any #PCDATA and all the XML structure will be imported directly as textual structure.

Supports various flavours of TEI P5 encoding semantics at the TEI level:

  • words and their properties: #PCDATA, <w>, <num>...
  • editorial markup: <sic>, <corr>...
  • texts and their properties: <TEI>, <text>...
  • intermediate text structures and their properties: <div>, <p>...
  • edition rendering: <pb/>, <p>, <lb/>...
  • what should not be indexed but considered for edition rendering: <teiHeader>, <note>...
  • alignment between texts: <teiCorpus>, <linkGrp>, <link>...
  • words identifier policy: @xml:id
  • language declaration policy: @xml:lang

See the "BFM encoding manual" for an example of TEI encoding practice interpreted by TXM, in French, http://bfm.ens-lyon.fr/article.php3?id_article=158.

The "TEI P5 BFM" TXM import module consists of Groovy and XSL scripts: they can be adapted directly by the user to any specific TEI encoding usage.

TXM Import Modules also provide various import parameters to tune each import process to specific data sources.

TEI sources from the following projects are currently imported into TXM:

TEI sources are preprocessed by several XSL stylesheets, one can find in TXM source code. Some of those stylesheets are available in the online TXM XSL stylesheets library: http://sourceforge.net/projects/txm/files/library/xsl

Programming Language(s)

TXM is written in the following programming languages:


Tech support

Tech support is mainly provided through two mailing lists (see below).

Users can also use 3 different trackers:

User community

Currently, the TXM user community communicates using two mailing lists and a wiki:

Training in the use of TXM is available every year at the CNRS summer school « Computing and Statistical Methods in Text Analysis » (MISAT), see http://laseldi.univ-fcomte.fr/ecole.

The JADT conference (http://jadt.org) is the main meeting place for the TXM user community.

Sample implementations

The standalone version of TXM is delivered with several sample corpora included, which can be directly analyzed from within TXM after installation.

The portal version of TXM has a demo running online at http://portal.textometrie.org/demo/?locale=en (work in progress).

A previous experiment of a web application based on TXM applied to one TEI encoded text can be found at http://txm.ish-lyon.cnrs.fr/txm.

Current version number and date of release

  • standalone: Current version is 0.7.2 released on Tuesday 2nd July 2013
