PhiloLogic

PhiloLogic is a "primary full-text search, retrieval and analysis tool" developed by the University of Chicago. PhiloLogic leverages the "wide array of XML data specifications and the recent deployment of basic XML processing tools provides an important opportunity for the collaborative development of higher-level, interoperable tools for Humanities Computing applications". Recognizing that the TEI community does not suit a one-size-fits-all approach, PhiloLogic focuses on the development of "specialized, interoperable tools" that can be implemented for end-user applications in a cost-effective manner. PhiloLogic is committed to the open source development of these applications: drawing on a wide range of technical abilities and expertise that is "not well supported by the commercial sector".

Kaleidoscope 2.0

Kaleidoscope is a tool designed to spot the differences in text files (text scope), images (image scope) and folders (folder scope) in seconds. Text scope allows user to compare different text files to spot difference and discrepancies. It also facilitates instantaneous merging of documents. Image scope provides four different comparative layouts that assist the user in spotting and analyzing the differences between image files. Images can be arranged two-up, one-up, split, or difference. Finally, folder scope allows users to compare directories and to clone files from one to the other.

Graphviz

"Graphviz is open source graph visualization software" that has been in constant development since 1988. Graph visualizations provide an avenue for representing information as abstract diagrams or networks. While originally designed for bioinformatics and software engineering, Graphviz is flexible in structure and is highly applicable to humanities work. Graphviz functions by transforming simple text language into useful diagrams. The user is able to customize the Graphviz graphics by altering the colour, fonts, nodes, layouts, hyperlinks, and shapes to create specialized diagrams specifically suited to the project's needs.

CulturalAnalytics

CulturalAnalytics is a program that facilitates "code for statistical analysis and plotting of image properties". CulturalAnalytics uses R to generate visualizations such as histograms, colour clouds, or image scatter charts. CulturalAnalytics was designed for use in the digital humanities and is of value to any scholar who is interested in analyzing digital or digitized images.

D3.js

D3.jx is a free, open source JavaScript library designed to manipulate documents based on user-specified data. "D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document". Using HMTL5, SVG, and CSS3, D3.js allows the user to bring data to life by creating visualizations with the "full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation".
