A Framework for Change Impact Analysis of Ontology-driven Content-based Systems

by Yalemisew M. Abgaz, Muhammad Javed, Claus Pahl
"... Abstract. The trend in content-based systems (CBSs) is shifting towards the use of ontologies to semantically enrich the content and increase its accessibility. The growing need of semantically rich content becomes a driving force for building ontology-driven content-based systems (ODCBSs). The buil ..."

Music part classification in content based systems

by Steven Blackburn, David De Roure - In 6th Open Hypermedia Systems Workshop , 2000
"... Abstract. In the Fourth Open Hypermedia Systems workshop, the authors presented scenarios and a set of prototype tools to explore the application of open hypermedia principles, including content-based navigation, to temporal media. The purpose of the current paper is to provide an update on this wor ..."

Clustering mechanism for content-based system in DHT-based overlay networks

by Emiliano Casalicchio, Federico Morabito, Fabrizio Davide, Giovanni Cortese
"... Abstract: A generic pub/sub communication system (often referred to in the literature as Event Service or Notification Service) is composed of a set of nodes distributed over a communication network. Clients to the systems are divided according to their role into publishers, which act as producers o ..."

-subscribe communication. We focus on content-based publish subscribe, and we explore an architectural options for realizing the broker overlay, namely peer-to-peer structured. We propose a novel adaptive content-based subscription management system, relying on a Distributed Hash Table routing infrastructure. We define a

A Content-based System for Music Recommendation and Visualization of User Preferences Working on Semantic Notions

by Dmitry Bogdanov, Martín Haro, Anna Xambó, Emilia Gómez, Perfecto Herrera
"... The amount of digital music has grown unprecedentedly during the last years and requires the development of effective methods for search and retrieval. In particular, contentbased preference elicitation for music recommendation is a challenging problem that is effectively addressed in this paper. We ..."

of musical preferences based on raw audio information. For the audio analysis we used the capabilities of the Canoris API. Thereafter, the system generates music recommendations, using a semantic music similarity measure, and a user’s preference visualization, mapping semantic descriptors to visual elements

Fab: Content-based, collaborative recommendation

by Marko Balabanovic, Yoav Shoham - Communications of the ACM , 1997
"... Fab is a recommendation system designed to help users sift through the enormous amount of information available in the World Wide Web. Operational since Dec. 1994, this system combines the content-based and collaborative methods of recommendation in a way that exploits the advantages of the two appr ..."

Content-based image retrieval at the end of the early years

by Arnold W. M. Smeulders, Marcel Worring, Simone Santini, Amarnath Gupta, Ramesh Jain - IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE , 2000
"... The paper presents a review of 200 references in content-based image retrieval. The paper starts with discussing the working conditions of content-based retrieval: patterns of use, types of pictures, the role of semantics, and the sensory gap. Subsequent sections discuss computational steps for imag ..."

Photobook: Content-Based Manipulation of Image Databases

by A. Pentland, R. W. Picard, S. Sclaroff , 1995
"... We describe the Photobook system, which is a set of interactive tools for browsing and searching images and image sequences. These query tools differ from those used in standard image databases in that they make direct use of the image content rather than relying on text annotations. Direct search o ..."

VisualSEEk: a fully automated content-based image query system

by John R. Smith, Shih-fu Chang , 1996
"... We describe a highly functional prototype system for searching by visual features in an image database. The VisualSEEk system is novel in that the user forms the queries by diagramming spatial arrangements of color regions. The system finds the images that contain the most similar arrangements of ..."

An efficient multicast protocol for content-based publish-subscribe systems

by Guruduth Banavar, Tushar Ch, Bodhi Mukherjee, Jay Nagarajarao, Robert E. Strom, Daniel C. Sturman , 1999
"... Abstract. The publish/subscribe (or pub/sub) paradigm is a simple and easy to use model for interconnecting applications in a distributed environment. Many existing pub/sub systems are based on pre-defined subjects, and hence are able to exploit multicast technologies to provide scalability and avai ..."

and availability. An emerging alternative to subject-based systems, known as content-based systems, allow information consumers to request events based on the content of published messages. This model is considerably more flexible than subject-based pub/sub, however it was previously not known how to efficiently

Matching Events in a Content-based Subscription System

by Marcos K. Aguilera , Robert E. Strom, Daniel C. Sturman, Mark Astley, Tushar D. Chandra , 2003
"... Content-based subscription systems are an emerging alternative to traditional publish-subscribe systems, because they permit more flexible subscriptions along multiple dimensions. In these systems, each subscription is a predicate which may test arbitrary attributes within an event. However, the mat ..."
