The most important feature of a search engine is that users can find what they are
looking for and; additionally, that they have a rich visual experience accessing all data
they need. The MOUVIZ dataset is mainly focused on names of artists, albums and
tracks, so we cannot provide enough information to the user unless we provide a
mechanism of population with that information. Users need a richer experience, for
example users are more comfortable if the interface has information in their native
language and if they have access to photos and navigate through interesting
information. But it is hard to populate the MOUVIZ dataset with more information
and to be updated with all information about artists. Therefore, there is a need of an
automatic mechanism to retrieve this information. In this project, I researched on an Interlinking Engine to provide augmented content to users by making an automatic relation between entities from our dataset and other Linked Open Data datasets, so we can use the information from other datasets to enrich our content. Also I research on searches with explicit and implicit scoring from users, where an user can give us his relevance scoring for a resource but we can capture some actions from user and identify an implicit scoring from this actions.

3. mouviz Introduction: User needs
• Users want to find what they are
looking for.
• MOUVIZ dataset is limited to few
information.
– It is needed a way to offer
richer information experience
to user.
• Language
• Data (Specially visual data)
• It is hard to populate data and be
updated.
– Needs an atomatic mechanism.
MOUVIZ Project 14.06.12 3
Positive user experience is a key factor in applications.
4. mouviz What can we provide?
• Searchs over MOUVIZ dataset.
• External resources about music:
– Linked Data
• Data can be extracted showed:
– Interlinking
– Augmented Content

8. mouviz Interlinking: 2º Semantic Approach
MOUVIZ Project 14.06.12 8
• Detection with 2 levels:
MusicBrainz
Music domain ontology
Translated to a common model
Reduction of Noise
12. mouviz DEMO
• Retrieve count of tracks per genre
• Retrieve count of tracks per artist in a genre
• Retrieve track list by genre, artist and album
• Retrieve information from one artist
• Retrieve interlinking information from one
artist

13. mouviz Results: Corpus & Setups
• MOUVIZ Ontology:
– Avg. relationships: 10.68
– Max: 36
– Min: 2
• Manual annotation of the corpus against
DBPedia and MusicBrainz.
– DBPedia: only well known artists.
– MusicBrainz: updated.
• Against 65K entities from these datasets.
• 3 Setups:
– DBPedia 1st relation level
– MusicBrainz 1st relation level
– MusicBrainz 2nd relation level
MOUVIZ Project 14.06.12 13
15. mouviz Conclusions (1/2)
• User can have a richer experience with Content
Augmentation.
• Specific domain ontology: best results
– Generic Domain ontology:
• Only well known artists and not updated.
• Without potential relationships (against MOUVIZ).
• Few number of relationships.
• More noise.
• Less relations and in more than one way (more complex structure
to translate to a common graph model).
MOUVIZ Project 14.06.12 15
16. mouviz Conclusions (2/2)
• Best results: translation to a common model and
depth to 2nd level.
• Difficulties found:
– Set a threshold.
– Normalize scoring.
• Future steps:
– Normalization/ Threshold
– Boosting of relationships/entities
