ZüKL offers various services to its members via its own servers. Below you find an overview. If you have any questions, do not hesitate to contact our server administrator Alexandra Bünzli.


  • File sharing: In principle, the institutes have to provide disk space for their members and projects. However, there are other possibilities as well.
    • Smaller projects are recommended to use the working group function built in to OLAT.
    • For UZH staff there is the possibility to share files in IBM connections (UZH internally; no students, exeptions may be granted on request). You can also create a community with a wiki or blog for your UZH research group.
    • Short-term sharing of (large) files can be done via the dropfiles service offered by the IT department.
    • A Dropbox alternative that operates under Swiss Law is SwitchDrive. You already have access with your UZH-AAI-Login.
    • If none of these possibilities work for you, the ZüKL server may be used to share data with colleagues after evaluation and if needed. This service is mainly intended for interdisciplinary groups which do not work at the same institute / research institution. Each user is allotted 5GB and each research group is allotted 20GB (negotiable). The ZüKL server should not be used as backup space - the Global Backup service of the IT department may be used for this. A special case is presented by completed corpora, which may be archived on the ZüKL server.


  • CQP (Corpus Query Processor) is a widely used corpus search tool that is part of the IMS Open Corpus Workbench (CWB). CQP is installed on the ZüKL server and is run via the terminal. For a more convenient graphical interface, you can use CQPweb in combination with your web browser. Access to corpora requires a password.
    ZüKL can help you with importing corpora into CQP and CQPWeb. However, projects are themselves responsible for transforming corpora into a form that is suitable for import. The import format is simple verticalised text.
    You'll find a demo page for CQPWeb here. Use "guest" as user name and password.
  • ANNIS3 (ANNotation of Information Structure) is a complex, browser-based tool for visualising and querying corpora with multiple annotation tiers, which has been developed in the SFB Information structure. ANNIS requires data in the PAULA format, a metastandard that is compatible with numerous XML annotation formats such as ELAN, EXMARaLDA, or MMAX.
    ZüKL offers its members access to ANNIS, including the possibility to query corpora via their web browser. Note that projects are responsible themselves for preparing their corpora for import into ANNIS. ZüKL offers support and advice.
    This page shows a demo corpus. Use "guest" as user name and password.

Other applications can be installed on request. For new requests, please contact the technical coordinator. The technical coordinator - in consultation with the Executive board if it is something that will take up a lot of resources - will decide if the requested application is going to be installed on a ZüKL server.

Also see this page for our guidelines for archiving corpora on the ZüKL server.

Corpus annotation

WebAnno is a browser-based tool to annotate corpora. Different annotation layers allow to encode various information, e.g. morphological, syntactical or semantic information.  The ZüKL has WebAnno installed and therefore provides the facility to annotate corpora via browser. If you are interested in using WebAnno, please contact the technical coordinator.

Other applications can be installed on request, for example brat rapid annotation tool (brat). There is a demo online. For new requests, the technical coordinator - in consultation with the Executive board if it is something that will take up a lot of resources - will decide if the requested application is going to be installed on a ZüKL server.


  • MySQL and PostgreSQL are database management systems based on the database language SQL. Both are in wide use, free, and open source. If you need to buil up a database you can, after confirmation, use the versions installed on the ZüKL server. However, we encourage members to make use of the database services of the UZH's IT department whenever possible.
  • FileMaker is another widely used database management system, which is commercial. Its main advantage is an intuitive graphical user interface that makes it easy to enter and show data. FileMaker databases can also be easily made accessible and editable for multiple users within or outside UZH via "Instant Web Publishing". Therefore, Filemaker Server Advanced is installed for you on the ZüKL server. With Instant Web Publishing, external users can access databases via their browser and do not have to own a FileMaker copy.

Other applications

  • R is a scripting language that is especially useful for transforming, analysing, and visualising quantitative data and that is more powerful than most readymade statistics packages - see the homepage of the R Project. R is installed on the ZüKL server.
  • iLex is a tool for sign language lexicography and corpus analysis. It is being developed at the University of Hamburg.
