Research Services at the RI


Central data register and repository service for language resources;

Store LR in a repository, make them accessible and visible via registry and linked meta-data services; PID – provide permanent address for each (version of each) resource in   repository; connected to register – possibility to search by meta-data; uniform descriptions, quality assessments etc;

Metadata portal, data category registration service, schema registration services for language resources;

Make it easier to find resources in both our LRCentre and connected networks via faceted search; properly described resources – automatically exchange meta-data in official formats with other language resource infrastructures (META-SHARE and CLARIN); Browsing schema in use for different types of language resources, registration of new schema;

Access to the resources and   tools deployed at the centre via specified and CLARIN compliant interfaces in a stable and persistent way;

Access rights to resources, tools based on their academic status (verified via SAML protocol) and for specific resources based on signed user licences; authentication of users via the national Identity Provider Federation (TAAT) that is connected to individual Identity Providers (e.g. University of Tartu) and other CLARIN IdPF. Ensure SSO (single-sign-on) capability for CLARIN network for both Estonian and international users; access to online tools and services;

Knowledge and expertise service for RI users;

User support;

Central IT-services as hosting, archiving, deposite, preservation of Estonian language and other linguistic data, users access and authorisation for services provided by national identity federation

Storage space, help with properly describing, licensing and standardizing   the resource, persistent access, but not (in general) updating resources   (e.g. to newer standards, newer software versions – but might provide e.g.  tools for automatic conversion from one standard format to another); version   management – will keep older versions (also useful e.g. to make it possible to repeat research experiments made using that resource); user and services’ usability statistics.

Equipment at the RI


Central servers for hosting, archiving and deposite of language resources and tools; Servers for producing and testing of research models;

Live Server (Supermicro 6037R) for hosting all live applications. the registry of language resources and the repository language resources. All of the resources will be listed in the registry and stored in the repository on a version-control software; Test Server (Supermicro 6037R); Storage (Infotrend ESDS S16E-R2240); Computational Server (Supermicro 5086B);

Web-based user environment for using language resources and tools for research and development purposes;

The registry of language resources; the repository of language resources; the web page of the Center of Language Resources; project management software; virtualization Software; version control software:

Description of the RI


The Center of Estonian   Language Resources (CELR) is an infrastructure which will provide access to language resources and technologies (language software, lexicons, text and speech corpora, linguistic databases) for all researchers, language   technologists and other people. To achieve this, the existing digital   archieves will be interconnected and supplemented by language technology tools as a web-based service which will use the archived/stored data. In CELR, the existing digital language resources will be interconnected and supplemented by language technology tools as an environment with web-based access and services which will use the archived/stored data. Estonia has set up the CELR as a consortium of three institutions at the national level on 2nd of December 2011. This consortium of University of Tartu, the Institute of Cybernetics at Tallinn University of Technology and the Institute of the Estonian Language will perform as organisational framework for coordinating and implementing the obligations of Estonia as the member in CLARIN ERIC. The CELR serves as the national node of CLARIN  infrastructure. In the start-up phase, Center will build up an infrastructure of central data register and service servers, user authentication and authorisation systems, system for gathering standardised, well-documented and evaluated collections of data.
