Multi-dimensional Learning on the Semantic Web
The Semantic Web effort is to evolve the web into a web of knowledge, of meaning, and its potential in education and learning cannot be overstated. The World Wide Web (WWW) has proved to be a great leveler for education nowadays a school in Calcutta has the access to same course materials as one in Cambridge or Canberra. The immense popularity of initiatives like Wikipedia [1] or MITs OpenCour...
متن کاملLearning Representations for Multi-Dimensional Sentiment Analysis
This document received 22 “You rock” reactions, 1 “Teehee” reaction, and 1 “Wow, just wow.” reaction. We can treat these reactions as a normalized distribution over reactions, [0.916, 0.041, 0, 0, 0.041]. Treating the reaction data as a normalized distribution allows us to ignore the differences in reaction counts across documents and instead focus only on how reactions are distributed within d...
متن کاملLearning Parametric Models for Social Infectivity in Multi-Dimensional Hawkes Processes
Efficient and effective learning of social infectivity presents a critical challenge in modeling diffusion phenomena in social networks and other applications. Existing methods require substantial amount of event cascades to guarantee the learning accuracy and they only consider time-invariant infectivity. Our paper overcomes those two drawbacks by constructing a more compact model and paramete...
متن کاملLearning Social Infectivity in Sparse Low-rank Networks Using Multi-dimensional Hawkes Processes
How will the behaviors of individuals in a social network be influenced by their neighbors, the authorities and the communities in a quantitative way? Such critical and valuable knowledge is unfortunately not readily accessible and we tend to only observe its manifestation in the form of recurrent and time-stamped events occurring at the individuals involved in the social network. It is an impo...
