CATMA

CATMA, short for Computer Assisted Text Markup and Analysis, is a web application for annotating and analysing texts. Researchers can use it alone or in teams, and it supports both qualitative and quantitative approaches. It runs in the browser and is described as free to use.

What CATMA offers

• Annotation — users mark passages of text much as they would in a printed book, including overlapping or competing readings.
• Custom tagsets — researchers build their own category schemes, either planned in advance or created as they go.
• Visualisation — results can be shown as word clouds, distribution graphs or Double Tree views.
• Collaboration — a corpus can be uploaded, shared and annotated together within a project.
• Multiple projects — one account can hold any number of projects with different team members.
• Documentation — guides cover the query language, data export formats, a JSON API and Git access.

Who it works with

The tool is built for digital humanities and literary researchers, and for seminars where students work on shared texts.
