Novel Metaknowledge-based Processing Technique for Multimedia Big Data clustering challenges
Past research has challenged us with the task of showing relational patterns
between text-based data and then clustering for predictive analysis using Golay
Code technique. We focus on a novel approach to extract metaknowledge in
multimedia datasets. Our collaboration has been an on-going task of studying
the relational patterns between datapoints based on metafeatures extracted from
metaknowledge in multimedia datasets. Those selected are significant to suit
the mining technique we applied, Golay Code algorithm. In this research paper
we summarize findings in optimization of metaknowledge representation for
23-bit representation of structured and unstructured multimedia data in order

Adaptive conflict-free optimization of rule sets for network security packet filtering devices
Packet filtering and processing rules management in firewalls and security gateways has become commonplace in increasingly complex networks. On one side there is a need to maintain the logic of high level policies, which requires administrators to implement and update a large amount of filtering rules while keeping them conflict-free, that is, avoiding security inconsistencies. On the other side, traffic adaptive optimization of large rule lists is useful for general purpose computers used as filtering devices, without specific designed hardware, to face growing link speeds and to harden filtering devices against DoS and DDoS attacks. Our work joins the two issues in an innovative way and defines a traffic adaptive algorithm to find conflict-free optimized rule sets, by relying on information gathered with traffic logs. The proposed approach suits current technology architectures and exploits available features, like traffic log databases, to minimize the impact of ACO development on the packet filtering devices. We demonstrate the benefit entailed by the proposed algorithm through measurements on a test bed made up of real-life, commercial packet filtering devices
Comprehensive Review of Opinion Summarization
The abundance of opinions on the web has kindled the study of opinion summarization over the last few years. People have introduced various techniques and paradigms to solving this special task. This survey attempts to systematically investigate the different techniques and approaches used in opinion summarization. We provide a multi-perspective classification of the approaches used and highlight some of the key weaknesses of these approaches. This survey also covers evaluation techniques and data sets used in studying the opinion summarization problem. Finally, we provide insights into some of the challenges that are left to be addressed as this will help set the trend for future research in this area.unpublishednot peer reviewe
