This book presents two collaborative prediction approaches based on
contextual representation and hierarchical representation, and their
applications including context-aware recommendation, latent
collaborative retrieval and click-through rate prediction. The proposed
techniques offer significant improvements over current methods, the key
determinants being the incorporated contextual representation and
hierarchical representation. To provide a background to the core ideas
presented, it offers an overview of contextual modeling and the theory
of contextual representation and hierarchical representation, which are
constructed for the joint interaction of entities and contextual
information.
The book offers a rich blend of theory and practice, making it a
valuable resource for students, researchers and practitioners who need
to construct systems of information retrieval, data mining and
recommendation systems with contextual information.
