Multi-agent-based hybrid peer-to-peer system for distributed information retrieval

Abstract

With the increasingly huge amount of data located in various databases and the need for users to access them, distributed information retrieval (DIR) has been at the core of the preoccupations of a number of researchers. Indeed, numerous DIR systems and architectures have been proposed including the broker-based architecture. Moreover, providing DIR with more flexibility and adaptability has led researchers thinking to build DIR with software agents. Thus, this research proposes a design and an implementation of a novel system based on the broker-based architecture and the peer-to-peer (P2P) network called broker-based P2P network. The proposed architecture is implemented with a multi-agent system (MAS) where the main agent playing the role of the broker, receives query from a peer agent and forwards them to other peer agents each with their index and resources. Upon completing retrieval process at each peer agent, results are directly sent to the peer agent that initiated the query without using the broker agent. Java Agent DEvelopment framework (JADE) is used to implement the agents and, for experiments, TERRIER (TERabyte RetRIEveR) is extended and used as the search engine to retrieve the Text Retrieval Conference (TREC) collections dataset notably TREC-6. The peer agent that originated the query progressively collects results coming from other peer agents, normalises and merges them and then proceeds with re-ranking. For normalisation, MinMax and Sum that are unsupervised normalisation methods are used.

Development of the digital retrieval system integrating intelligent information and improved genetic algorithm: A study based on art museums

“…Image retrieval operations allow users to search based on attributes to quickly and accurately find the desired cultural relics image. Meanwhile, image review ensures the quality and accuracy of these image data and the credibility of the entire database [ 27 ]. Through the synergy of these two modules, the proposed system can offer efficient image data management and retrieval functions, providing strong support for the digital management of art museums.…”

“…Such database support provides a real and representative data scenario for the system prototype in this study, to better verify the system's performance in image data processing and analysis [25]. In the user management module, flexible management of system user rights is realized to meet different user roles' requirements [26]. The layered architecture ensures that administrators can effectively add, delete, and modify users, thus realizing the comprehensive management of user information.…”

Education Exchange Storage Protocol: Transformation Into Decentralized Learning Platform

“…This solution will help inefficient management of LCMS components and improve the performance of LCMS through the RLO. There is even an online reinforcement learningbased approach developed by the authors of (Pouamoun and Kocabaş, 2021) to take advantage of the dynamic run-time characteristics of the P2P IR system represented by information about previous search sessions. Therefore, there is still scarcity in locating in-depth research regarding integration of P2P, blockchain, and decentralized storage to be used in micro-teaching processes.…”

Research on Efficient Retrieval Method of Key Information of Discipline Inspection and Supervision Based on Digital Technology

“…Secondly, information sharing and integration still need to be further strengthened. Although the discipline inspection and supervision organs have established a relatively perfect information system, the degree of information sharing and integration among different regions and departments is still insufficient [5][6][7] . In the future, we should further promote information sharing and integration between different systems and departments, break the phenomenon of information islands and improve the comprehensiveness and integrity of information.…”
