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. Discrete components (written in Java or C++) may be used within the application, such as language identification or entitiy detection. Each component provides self-describing metadata via XML descriptor files.

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.
