Article No.: 6
DOI: 10.1145/2542182.2542188

Social media data are produced continuously by a large and uncontrolled number of users. The dynamic nature of such data requires the sentiment and topic analysis model to be also dynamically updated, capturing the most recent language use of...

Personalized emerging topic detection based on a term aging model
Mario Cataldi, Luigi Di Caro, Claudio Schifanella
Article No.: 7
DOI: 10.1145/2542182.2542189

Twitter is a popular microblogging service that acts as a ground-level information news flashes portal where people with different background, age, and social condition provide information about what is happening in front of their eyes. This...

Forecasting with twitter data
Marta Arias, Argimiro Arratia, Ramon Xuriguera
Article No.: 8
DOI: 10.1145/2542182.2542190

The dramatic rise in the use of social network platforms such as Facebook or Twitter has resulted in the availability of vast and growing user-contributed repositories of data. Exploiting this data by extracting useful information from it has...

Campaign extraction from social media

Article No.: 10
DOI: 10.1145/2542182.2542192

Online social networking sites have become increasingly popular over the last few years. As a result, new interdisciplinary research directions have emerged in which social network analysis methods are applied to networks containing hundreds of...

Community detection and visualization in social networks: Integrating structural and semantic information
Juan David Cruz, Cécile Bothorel, François Poulet
Article No.: 11
DOI: 10.1145/2542182.2542193

Due to the explosion of social networking and the information sharing among their users, the interest in analyzing social networks has increased over the recent years. Two general interests in this kind of studies are community detection and...

Personalized tag recommendation based on generalized rules
Luca Cagliero, Alessandro Fiori, Luigi Grimaudo
Article No.: 12
DOI: 10.1145/2542182.2542194

Tag recommendation is focused on recommending useful tags to a user who is annotating a Web resource. A relevant research issue is the recommendation of additional tags to partially annotated resources, which may be based on either personalized or...

Active learning strategies for rating elicitation in collaborative filtering: A system-wide perspective
Mehdi Elahi, Francesco Ricci, Neil Rubens
Article No.: 13
DOI: 10.1145/2542182.2542195

The accuracy of collaborative-filtering recommender systems largely depends on three factors: the quality of the rating prediction algorithm, and the quantity and quality of available ratings. While research in the field of recommender systems...
