Versioning Machine

The Versioning Machine, now in version 4.0, is a framework and an interface for displaying multiple versions of text, and encodes the text according to TEI guidelines. It incorporates features found in both critical editions and electronic publication, in addition to providing an environment for textual editors to comparatively view the results of their edits. This tool may be downloaded for use on a local machine, or hosted on one's server for web usage.

Apache UIMA

Apache UIMA (Unstructured Information Management application) is a software system for analyzing large amounts of unstructured data, such as a plain text document, and identifying entities, such as persons, places, organizations, or relations between entities.

Visualization

DocuBurst

DocuBurst is a free web-based visualization tool for exploring the contents of a text. Visitors can upload their own text or view those provided by others. DocuBurst presents an interactive chart called a ‘radial sunburst’ diagram which organizes the nouns extracted from the user-supplied text based on their meaning, and colours them based on frequency, revealing common themes in the text. The visualization also shows the proper nouns (e.g. character names) in a linked word cloud. The visualization may be zoomed, filtered, or refocused to target types of words of interest (e.g. “animal” words or “feeling” words). The visualization also provides a comparison tool to contrast word use across two documents. DocuBurst views can be bookmarked, annotated, shared, and embedded in your own website.

EURAC: Double Tree

Double Tree is a free, open source Java application providing a visualization component for supporting exploratory corpus analysis. It focuses particularly on analyzing concordances, and can also represent a KWIC for a single word by collapsing the contexts into a double sided tree. Each side of the tree can be expanded independently to browse the results.

EURAC: End to End

End to End is a visualization application for exploratory corpus analysis focused on collocations. This tool starts with two words and constructs a visual network of all collocations of those words within the corpus, while its interface enables interactive zooming and browsing of the resultant graph. Note: this tool is unavailable until licensing issues are resolved.
