Topic Segmentation: Algorithms And Applications
Most documents are aboutmore than one subject, but the majority of natural language processing algorithms and information retrieval techniques implicitly assume that every document has just one topic. The work described herein is about clues which mark shifts to new topics, algorithms for identifying topic boundaries and the uses of such boundaries once identified. A number of topic shift indic...
متن کاملNetworking for Multimedia Tech Topic #04: Multimedia Applications
Certainly an epic paper insofar as it presents nothing less than a new sub-area for multicast applications, complete with critical research problems, an existing and even somewhat vetted prototype, as well as simulations showing scalability and general betterness. Published in IEEE Transactions on Knowledge and Data Engineering, it focuses on a new system concept for content delivery and largel...
متن کاملAlgorithms for Generalized Topic Modeling
Recently there has been significant activity in developing algorithms with provable guarantees for topic modeling. In this work we consider a broad generalization of the traditional topic modeling framework, where we no longer assume that words are drawn i.i.d. and instead view a topic as a complex distribution over sequences of paragraphs. Since one could not hope to even represent such a dist...
متن کامل3D modeling for multimedia applications
Image coding standards usually focus on storing and transmitting signals efficiently, in a frame based approach. The coming MPEG-4 standard [1] adds a new challenge, namely bringing new services to image communication users. It moves towards representing a scene as a composition of audiovisual objects rather than "just" a collection of pixels. MPEG-4 objects can be captured naturally by one (or...
متن کاملTopic Modeling for Large-Scale Multimedia Analysis and Retrieval
The explosion of multimedia data in social media raises a great demand for developing effective and efficient computational tools to facilitate producing, analyzing, and retrieving large-scale multimedia content. Probabilistic topic models prove to be an effective way to organize large volumes of text documents, while much fewer related models are proposed for other types of unstructured data s...
