First, the cold-start problem would be solved since the Web of Data already contains information that can be used to support educators when discovering educational ICT tools, as evaluated in a previous research work by the authors (Ruiz-Calleja, VegaGorgojo, Asensio-Perez, et al.
On the other hand, the Review Vocabulary (Heath & Motta, 2007) is used as a base to describe reviews since it is commonly employed for this purpose in the Web of Data.
The aim of SEEK-AT-WD software architecture is to sustain a registry of educational ICT tools (F3) retrieving information from the Web of Data (F1) and educational annotation tools (F4).
In addition, this approach allows crawling the Web of Data: Once DBpedia mappings are defined, the relationships between SEEK Ontology and other linked vocabularies can be automatically inferred following the links that are published on the Web of Data.
This evaluation first focuses on SEEK-AT-WD crawler, analyzing the tool descriptions it gathers from the Web of Data.
Obtaining educational ICT tool descriptions from the Web of Data
The first evaluation task analyzes the tool descriptions inferred by SEEK-AT-WD crawler out of the information retrieved from the Web of Data.
Again, these results are very satisfactory, but the tool descriptions retrieved from the Web of Data can be improved by the community of educators if a social annotation tool is available.
es/upload/ and is currently published by SEEK-AT-WD (and hence queried by U-Seek) in conjunction with the data retrieved from the Web of Data.
Evaluation results show that a big collection of ICT tool descriptions can be automatically obtained from the Web of Data and related to SEEK Ontology.
Hence, the envisioned usage scenario is supported by SEEKAT- WD: educational queries can be submitted to obtain descriptions of ICT tools that someone published in the Web of Data in conjunction with educational reviews of these same tools.
Moreover, as the Web of Data is periodically crawled, these tool descriptions are automatically updated and new ones can be discovered.
