XML-based Selective Dissemination of Information (SDI) systems aims to quickly deliver useful information to the users based on their profiles or user subscriptions. These subscriptions are specified in the form of XML queries. This paper investigates how clustering and aggregation of user queries can help scale SDI systems by reducing the number of document-subscription matchings required. We ...

We introduce in this paper a generic architecture to deal with the general problem: “How to Deliver the Right Information to the Right User?”. We discuss this issue through the proposal of our SDI (Selective Dissemination of Information) Personalised Architecture, called MySDI, which is based on the software agent paradigm as well as on information retrieval techniques. In order to clarify and ...

New methods and new systems are needed to lter or to selectively distribute the increasing volume of electronic information being produced nowadays. An e ective information ltering system is one that provides the exact information that ful lls a user's interest with the minimum e ort by the user to describe it. Such a system will have to be adaptive to the user changing interest. In this paper ...

Users of Institutional Repositories and Digital Libraries are known by their needs for very specific information about one or more subjects. To characterize users profiles and offer them new documents and resources is one of the main challenges of today's libraries. In this paper, a Selective Dissemination of Information service is described, which proposes an Ontology-based Context Aware syste...

Information Dissemination applications are gaining increasing popularity due to dramatic improvements in communications bandwidth and ubiquity. The sheer volume of data available necessitates the use of selective approaches to dissemination in order to avoid overwhelming users with unnecessaryinformation. Existing mechanisms for selective dissemination typically rely on simple keyword matching ...

The postharvest phase has been consideredan environment for successful application of biological control agents (BCAs). However, the interactions between fungal pathogen, host (fruit), and antagonist are influenced by several parameters such as temperature, oxidative stresses, oxygen composition and water activity that could determine the success of biocontrol. Knowledge of the modes of action ...

This paper presents the results of a heuristic-based user interface evaluation of the Gateway to Electronic Media Services (GEMS) system at Nanyang Technological University(NTU) in Singapore. GEMS provides access to multimedia resources, bibliographic information, electronic document management, selective dissemination of information (SDI), booking of facilities, and several other services. Res...

Automatic data dissemination systems are becoming increasingly relevant in internet-based information systems. In such systems, users subscribe to the dissemination service by providing interest profiles. These profiles are then used to determine which information should be delivered to which users, whenever new information is entered into the system. A main shortcoming of existing disseminatio...

The primary objective of document annotation in whatever form, manual or electronic is to allow those who may not have control to original document to provide personal view on information source. Beyond providing personal assessment to original information sources, we are looking at a situation where annotation made can be used as additional source of information for document tracking and recom...
