A Software Architecture for Progressive Scanning of On-line Communities
Roberto Baldoni, Fabrizio d’Amore, Massimo Mecella, Daniele Ucci · 2014
We consider a set of on-line communities (e.g., news, blogs, Google groups, Web sites, etc.). The content of a community is continuously updated by users and such updates can be seen by users of other communities. Thus, when creating an update, a user could be influenced by one or more updates creating a semantic causal relationship among updates. This transitively will allow to trace how an information flows across communities. The paper presents a software architecture that progressively scan a set of on-line communities in order to detect such semantic causal relationships. The architecture includes a crawler, a large scale storage, a distributed indexing system and a mining system. The paper mainly focuses on crawling and indexing.
