Chapitres de Livre : Titre du livre: "NoSQL Data Models - Trends and Challenges", July 2018, John Wiley & Sons, pp. 193--226, (isbn: 978-1-78630-364-6)Mots clés: Pub/Sub, NoSQL, TDV, Streaming
Résumé:
This chapter focuses on the way to enhance relevance of filtering and to integrate such a process in two different implementations: a centric-based version and a distributed version in a NoSQL environment. Our contributions in this paper are:
– definitions for novelty and diversity in this particular context, along with a pro- posal for a weighting score (Term Discrimination Values - TDV) adapted to the characteristics of items and subscriptions;
– an efficient filtering algorithm for real-time Pub/Sub systems based on novelty and diversity which exploits redundancy between subscriptions’ history. Two optimized implementations are proposed in centralized and distributed contexts;
– a validation which highlights the complementarity of novelty and diversity both in centralized and NoSQL environments;
– enhancement of TDV [WIL 85] computation by proposing incremental versions in a distributed environment.
