This book explains, collects and reports on the latest research results that aim at narrowing the so-called multimedia "Semantic Gap": the large disparity between descriptions of multimedia content that can be computed automatically, and the richness and subjectivity of semantics in user queries and human interpretations of audiovisual media. Addressing the grand challenge posed by the "Semantic Gap" requires a multi-disciplinary approach (computer science, computer vision and signal processing, cognitive science, web science, etc....

.When Mandy Brown, Jason Santa Maria and I formed A Book Apart, one topic burned uppermost in our minds, and there was only one author for the job. Nothing else, not even “real fonts” or CSS3, has stirred the standards-based design community like the imminent arrival of HTML5. Born out of dissatisfaction with the pacing and politics of the W3C, and conceived for a web of applications (not just documents), this new edition of the web’s lingua franca has in equal measure excited, angered, and confused the web design...
Community-based question answer (Q&A) has become an important issue due to the popularity of Q&A archives on the web. This paper is concerned with the problem of question retrieval. Question retrieval in Q&A archives aims to ﬁnd historical questions that are semantically equivalent or relevant to the queried questions. In this paper, we propose a novel phrase-based translation model for question retrieval.
Named Entity Extraction is a mature task in the NLP ﬁeld that has yielded numerous services gaining popularity in the Semantic Web community for extracting knowledge from web documents. These services are generally organized as pipelines, using dedicated APIs and different taxonomy for extracting, classifying and disambiguating named entities. Integrating one of these services in a particular application requires to implement an appropriate driver. Furthermore, the results of these services are not comparable due to different formats.
Quantifying the semantic relevance between questions and their candidate answers is essential to answer detection in social media corpora. In this paper, a deep belief network is proposed to model the semantic relevance for question-answer pairs. Observing the textual similarity between the community-driven questionanswering (cQA) dataset and the forum dataset, we present a novel learning strategy to promote the performance of our method on the social community datasets without hand-annotating work. ...
Human beings communicate in four ways.We listen, speak, read, and write.When you were a baby the first
thing you did was listen to the world around you. You recognized voices; you were startled by noises; you
were soothed by music. Then you began to imitate the sounds you heard and you experimented by creating
your own sounds. You learned that crying brought attention, words identified things, and that linking words
together made meaning. Then you learned that symbols on a page held unique meaning, and you learned to
Believe it or not, when we were kids the standard way to send a message to a friend or family member
was by mail. Not e-mail, mind you, but the physical kind requiring a stamp on the envelope. Fax
machines came blazing onto the scene and revolutionized communications because, all of a sudden,
you could send a document across the country in a matter of minutes, rather than a number of days.
Personal computers were starting to show up in houses, but they generally cost an arm and a leg,
and they certainly did not have any sort of way of communicating with the outside...
To take our users’ Semantic Web experience further, we have created Semantic Bank, a com-
munal repository of RDF to which a community of Piggy Bank users can contribute to share the
information they have collected. Through Semantic Bank, we introduce a mechanism for light-
weight structured information publishing and envision collaborative scenarios made possible by
