SEEK-AT-WD (Support for Educational External Knowledge About Tools in the Web of Data) is an infrastructure that collects descriptions of ICT tools available at the Web of Data and adapts them to be used for educational purposes. Tools are described using several educational vocabularies, such as Ontoolcole and the SEEK Ontology, as well as somo other well-known vocabularies: DBpedia Ontology, FOAF, RDFS, OWL, UMBEL and others. All the data provided by SEEK-AT-WD comes from third-party Linked Data sources.

SEEK-AT-WD is a research work of the Intelligent & Cooperative Systems Research Group (GSIC). All its data is maintained by Adolfo Ruiz Calleja, who designed, developed and evaluated SEEK-AT-WD as part of his PhD thesis.


SEEK-AT-WD data is available in RKB Explorer repository, a human interface to the ReSIST knowledge base. RKB Explorer is currently hosted by the School of Electronics and Computer Science at the University of Southampton (UK).

You can use SEEK-AT-WD dataset clicking here. Data can be accessed submitting SPARQL queries to its query interface
Some examples of queries that you can submit are the following ones:
"Free tools that allow the construction of multimedia documents"
"Latex editor for Windows"

You can also crawl the dataset. Following the Linked Data best practices, a Concise Bounded Description is provided for each URI described in SEEK-AT-WD namespace. Some examples are the following URIs:

Finally, some applications that make use of SEEK-AT-WD have already been developed.

The first one is a search client called U-SEEK, has been developed to support educators the creation of queries and the visualization of the results. U-SEEK can be accessed here.

The second one is We-Share, a social annotation tool that allows educators to search, browse and enrich the data published on SEEK-AT-WD.

Questionnaires and evaluation

February 2012: Four tool providers from two different research groups were asked to fill in a questionnaire about their requirements when publishing tools in educational registries. Results can be found here

February 2012: Three administrators of educational tool registries from two different research groups were asked to fill in a questionnaire about their tasks when managing their registries. Results can be found here

June 2011: A group of sixteen teachers were asked to understand which information sources they manage when selecting an appropriate software tool to support their learning settings. Here you can find their answers.

June 2011: Two groups of fourteen practitioners were asked to send queries to be posted to SEEK-AT-WD; then, SEEK-AT-WD answers were evaluated. First group (CSCL practitioners) results can be found here while second group (non-CSCL practitioners) results can be found here.

March 2013: A group of 23 educators were involved in an e-mail-mediated experiment where they first used We-Share to publish data and then they were asked to search for tools with and without the data published using We-Share. The participants profiles are here. The e-mails sent to the participants can be found here. The questionnaires offered can be seen here and their answers are available here.
