“Cesax” is a computer program that handles several different types of syntactically parsed files. It allows semi-automatic coreference resolution for its own native psdx format. Cesax can handle files of the following types:

 

1.      Psd      - Text files that are part of the parsed series of English corpora (YCOE, PPCME2 etc)

2.      Psdx    - XML equivalents of psd files

3.      Tig      - Negra (Tiger) format (stand-off xml).

4.      Xml     - Alpino-produced xml format
