Research Questions
 Q1: How can multimedia content be semantically
annotated and seamlessly connected with other resources on
the Web?
 Q2: Can those semantic annotations and linked media
resources bring value for the exploitation and consumption
of multimedia content?
 Q3: Is it possible to automatically contextualize news
stories with background information so they can be
effectively interpreted by humans and machines?

Bringing Multimedia to the Web
Why?
  Make video a first citizen of the Web
  Make video universally accessible and
shareable at different granularities
(segments)
  Benefit from the vast knowledge already
present on the Web

Conclusions
a.  Applied NER and NED as semantic annotation techniques in the
multimedia domain
b.  Developed other techniques such as Named Entity Expansion or
Visual Concept Mapping
c.  LinkedTV model to harmonize annotations into the Linked Data Web
Q1: How can multimedia content be semantically
annotated and seamlessly connected with
other resources on the Web?
Q2: Can those semantic annotations and linked
media resources bring value for the exploitation
and consumption of multimedia content?
a.  Exploiting multimedia semantic techniques: enriching, highlighting
media fragments (hotspots), classifying videos…
b.  Evaluation of multimodal approaches via Mediaeval 2013/2014

Conclusions
a.  Proposed the NSS model and a Gold Standard
b.  The multidimensional nature of the entity relevance
•  Gaussian function, popularity, experts rules…
c.  Concentric model better reproduces the NSS:
•  Better Compactness: 36.9% over BAS01 (similar recall, smaller size)
•  Core/Crust brings up relevant entities without having to deal with
fuzzy dimensions
d.  NSS better supports the news consumption phases:
(Before, During, After)
Q3: Is it possible to automatically contextualize news
stories with background information so they can
be effectively interpreted by humans and
machines?

Future Work
•  [S] Publish generated NSS on the Web (Linked Data)
•  [S] Extend the Gold Standard:
•  From 5 to 23 videos, concentric based model for candidate selection
•  Submission to TOIS
•  [S] Not depending on “big players” for retrieving
knowledge during the expansion phase
(Terrier VS Google experiments)

Future Work
•  [M] Using the power of crowdsourcing in Gold Standard
creation
•  Increase size of the Gold Standard without involving
experts
•  Consider different levels of entity relevancy
•  [M] Supervised techniques: Learn to Rank
•  Features in entities: surface forms, URL’s, types…
•  Features in documents, sources, and other provenance

Future Work
•  [L] Spot not only the strength of the relationships
between Crust and the Core, but also the predicates

Future Work
•  [L] Not having to rely on “Big Players” during Crust
generation:
•  Continuous indexing
•  Better curated white lists
•  Fresher structured databases: DBpedia events
•  [L] Reusing concentric model in context-related tasks:
•  Name Entity Extraction/Disambiguation
"  As another feature similar to BagOfWords, Word2vec…
•  Exploratory Searches
"  Diversity, serendipity…
