Register with CATMA

In order to work actively with CATMA you need to create a password secured account that is associated with an active email address. CATMA offers two authentication options:

  • creation of a user account via Google’s authentication system. If you use this system Google’s Privacy Policy will apply to your account.
  • creation of a user account with CATMA’s own authentication system. If you use this system, your account data will be accessible to the CATMA system only.

Irrespective of the authentication system chosen all your account details are stored for internal authentication purposes only – CATMA does not pass on your personal data to any third party whatsoever. However, please note that any texts/corpora and/or Tagsets uploaded to CATMA, as well as any meta data generated with the CATMA web application is automatically linked to your user account. This is necessary to allow persistent access during a work session and between work sessions, and to enable collaboration in text analysis and annotation with CATMA.

Sharing data with others

When you use the “sharing” option in CATMA either actively (i.e., you “share” your documents with others) or passively (i.e., you accept somebody else’s invitation to join a group of users who share documents in CATMA) your user identity will be displayed to all other members of the sharing group in the format which you defined when uploading, creating or editing a document (a primary text, Tagset, Annotation collections etc.).

Log Files and cookies

CATMA uses log files and internal cookies to enable certain features of the application. Log files are a means of documenting certain events, which occurred during a web-session. Cookies are small pieces of information about a user’s behavior on a website sent from this website to a user’s web browser. By “internal cookies” we mean cookies, that are generated by CATMA without using any third party plugins. The information collected by log files and internal cookies include internet protocol (IP) addresses and behavioral data. These are used to enable some of the core features of the CATMA-application such as saving annotations on texts or linking corpora to specific user profiles.

CATMA reserves the right to post-process and analyze as training data for machine learning purposes any data and metadata contributed or generated by a user. Any user generated data/metadata used for these purposes will be processed strictly in anonymized format only and will not be used to profile individual users under any circumstances whatsoever.

The developers of CATMA gather data from the site about what tools are invoked and with what parameters (IP addresses are logged to detect and fix bugs and other unwanted behaviour). In addition, locally logged data helps the development team to debug and improve the tools, as well as to understand how researchers are using them. CATMA guarantees that any such data is strictly used in anonymous and aggregate form only.

You can choose to disable cookies through your individual browser options. But please be aware that some of the core features of the CATMA application might not perform when cookies are disabled. To know more detailed information about cookie management with specific web browsers, it can be found at the browsers’ respective websites.
