Recommender System for the DSpace

A Recommender System for the DSpace Open Repository Platform by Desmond Elliott, James Rutherford, and John Erickson. HPL-2008-21.

We present Quambo, a recommender system add-on for the DSpace open source repository platform. We explain how Quambo generates content recommendations based upon a user selected set of examples, our approach to presenting content recommendations to the user, and our experiences applying the system to a repository of technical reports. We consider how Quambo could be combined with the peer-federated DSpace add-on to extend the item-space from which recommendations can be generated; a larger item-space could improve the diversity of the set from which to make recommendations. We also consider how Quambo could be extended to add collaboration opportunities to DSpace. Publication Info: Submitted to Open Repositories 2008, Southampton, UK, April 1-4, 2008

Controlled Vocabulary Add-on for DSpace

The Odisseia Research Group at the University of Minho has just released a new version of the Controlled Vocabulary add-on for DSpace.

This patch adds a few improvements to the controlled vocabulary add- on currently present in DSpace:

1. The Node Schema (see [dspace]/docs/controlledvocabulary.xsd) has been updated to support other types of relationships and/or properties that are part of a true thesaurus, and now all elements in this structure are properly processed and displayed by the add-on.
2. The add-on recognizes thesaurus/controlled vocabularies described in SKOS standard schema. This vocabulary can be created according to the W3C recommendations and must be saved with the extension ".skos".
3. In the DC metadata fields you wish to control, it is now possible to configure distinct vocabularies associated to specific communities. You may also define one or more generic vocabularies to be used by default on the rest of the communities. To use this functionality you have to edit the file [dspace]/config/input- forms.xml and place a new "controlled-vocabularies" element under the that you want to control.
