The cross-platform Advene application allows users to easily create comments and analyses of video documents, through the definition of time-aligned annotations and their mobilisation into
automatically-generated or user-written comment views (HTML documents). Annotations can also be used to modify the rendition of the audiovisual document, thus providing virtual montage, captioning, navigation... capabilities. Users can exchange their comments/analyses in the form of Advene packages, independently from the video itself.

This online tool can be used for a wide variety of annotation tasks, including visualization and collaboration.
brat is designed in particular for structured annotation, where the notes are not freeform text but have a fixed form that can be automatically processed and "interpreted" by a computer. brat also supports the annotation of n-ary associations that can link together any number of other annotations participating in specific roles. brat also implements a number of features relying on natural language processing techniques to support human annotation efforts.
The Classical Text Editor was designed to enable scholars working on a critical edition or on a text with commentary or translation to prepare a camera-ready copy or electronic publication without bothering much about making up and page proofs. Its features, formed in continuous discussion with editors using the program, meet the practical needs of the scholar concerning text constitution, entries to different apparatus and updating them when the text has been changed, as well as creating and redefining sigla.
Parts-of-Speech (POS) tagging software - the classification of words into one or more categories based upon its definition, relationship with other words, or other context. CLAWS (Constituent Likelihood Automatic Word-tagging System) uses several methods to identify parts of speech., most notably a system called Hidden Markov models (HMMs) which involve counting cases and making a table of the probabilities of certain sequences of words.
