2013 Proceedings of the 9th International Conference on Semantic Systems - I-SEMANTICS '13  
Exploratory search systems help users learn or investigate a topic. The richness of the linked open data can be used to assist this task.  ...  It is used by the Discovery Hub exploratory search system to select interesting resources, to support faceted browsing of the results, to provide explanations and to offer redirections to third-party services  ...  We will also study how several linked data sources can be combined with the proposed approach.  ...

Harvesting social knowledge from folksonomies

Harris Wu, Mohammad Zubair, Kurt Maly
2006 Proceedings of the seventeenth conference on Hypertext and hypermedia - HYPERTEXT '06  
Collaborative tagging systems, or folksonomies, have the potential of becoming technological infrastructure to support knowledge management activities in an organization or a society.  ...  The goal of the algorithm is to find hubs, the documents that link to many high quality documents, and authorities, the documents that are linked from many high quality documents.  ...  Users simply create and apply tags on the fly. Folksonomies are inherently open-ended and therefore respond quickly to changes and innovations in the way users categorize content.  ...

Survey on PAODV for Link Breaks Detection and Route Repairs

2020 International Journal for Research in Applied Science and Engineering Technology  
The essential is link break location time (), utilizing the HELLO message to identify interface disappointment, and hence the subsequent one is the link break position boundary () for AODV nearby route  ...  In AODV, a hub will trade occasional HELLO messages with its neighbor, in order to work out the connection's state and to point that the connection keeps on being alive.  ...  So on beat this issue, we propose a connection mindful on request directing convention or link aware on demand routing protocol (LAOD).  ...
