Search

This paper proposes a Neurocomputing application that reorders the Web results obtained from different Web Search Engines emulating the way our brain takes decisions. The proposed application is based on the Random Neural Network with Deep Learning Clusters that evaluates and adapts Web result relevance by associating independently each Deep Learning Cluster to a specific Web Search Engine. In addition, this paper presents a Deep Learning Cluster to perform as a Management Cluster that decides the final result relevance based on the inputs from each independent Deep Learning cluster. The performance of the proposed Management Cluster is evaluated when included as an additional layer to the Deep Learning Clusters. On average; the proposed Deep Learning cluster structure improves Smart Search performance. [ABSTRACT FROM AUTHOR]

Web users are not assured that the results provided by Web search engines or recommender systems are either exhaustive, or even the most relevant to their search needs. Businesses that provide services through the web have a commercial interest to rank higher on results or recommendations to attract more customers, while Web search engines and recommender systems make a profit based on the advertisers that can offer a higher payment for their advertisements. Thus we propose a neuro-computing application that addresses these issues from the perspective of end-users. We present an Intelligent Search Assistant (ISA) that acts as an interface between the user and different search engines. Using the Random Neural Network as a learning engine that operates with learned by gradient descent and reinforcement learning, the ISA learns how to reorder results and present them to the end-user, according to the perceived relevance of the results for the end-user's benefit. We also present a new relevance metric, which combines both relevance and rank, to validate and compare the performance of our proposed solution against other Web search engines and recommender systems. The resulting rank relevance provided by different Web search engines, metasearch engines, academic databases and recommender systems are compared with the ISA, which appears to outperform commercial search tools.
