CATPAC
CATPAC is a program available for purchase designed to summarize a text's main ideas. It is multilingual and primarily aimed at researchers in the sciences, and can handle large volumes of text. Text must be formatted in ASCII or RTF.
The CATPAC website is no longer available or maintained as of 2014. An archived version of the site and its information can be viewed via the Internet Archive.
The SSH Open Marketplace is maintained and will be further developed by three European Research Infrastructures - DARIAH, CLARIN and CESSDA - and their national partners. It was developed as part of the "Social Sciences and Humanities Open Cloud" SSHOC project, European Union's Horizon 2020 project call H2020-INFRAEOSC-04-2018, grant agreement #823782.
