The Integrated Learning Design Environment is a social platform focused in supporting
teachers in the computer-assisted design of Learning activities. In this platform, teachers
and course designers can contextualize, author and share their designs within their
community. This social component, of the ILDE, would benefit from the application of
Information Retrieval and Natural Language Processing techniques to facilitate teachers
and course designers to find shared designs as fast and efficient as possible. In this work,
we use Natural Language Processing to classify learning designs written in Catalan, get
the content of the users, parse this content with Freeling and extract education domainspecific
terminology from the documents. To extract the terminology, a combination of
two methods is used. The first method uses the Multilingual Central Repository ontology
to check if a term belongs to any of four pedagogical fields. The second methodology,
computes the tf-idf of all the documents terms using a non-domain-specific corpus, the
Catalan Wikipedia. This work also discusses the potential of the proposed combination
of methods to retrieve simple and complex terms from documents. The resulting
combined method distributes the weight of each method in the extraction process to assign
a score to each retrieved term. After this process of extracting education domain-specific
terminology from different ILDE documents, it has been created a Document Similarity
Application addressed to teachers and course designers. This application allows users to
search documents based on the similarity between these documents and another document
of the same ILDE community. Besides, given a document, users can visualize the
education terminology that belongs to that document. Finally, users can also search for
certain documents using a terminology-based query to obtain a set of documents and their
similarity with respect to that query.
