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.

基于多主体的混合对等分布式信息检索系统

随着各种数据库中越来越多的数据以及用户访问它们的需求,分布式信息检索(DIR)已成为许多研究人员关注的核心。实际上,已经提出了许多DIR系统和体系结构,包括基于代理的体系结构。此外,为DIR提供更大的灵活性和适应性使研究人员开始考虑使用软件代理构建DIR。因此,本研究提出了一种基于基于代理的体系结构和称为基于代理的P2P网络的对等(P2P)网络的新颖系统的设计和实现。所提议的体系结构是通过多代理系统(MAS)实施的,其中主要代理扮演经纪人的角色,接收来自对等代理的查询,并将查询及其索引和资源转发给其他对等代理。在每个对等代理处完成检索过程后,结果将直接发送到发起查询的对等代理,而无需使用代理代理。Java代理开发框架(JADE)用于实现代理,并且为了进行实验,扩展了TERRIER(TERabyte RetRIEveR)并用作搜索引擎来检索文本检索会议(TREC)集合数据集,特别是TREC-6。发起查询的对等代理逐渐收集来自其他对等代理的结果,对其进行规范化和合并,然后继续进行重新排名。对于归一化,使用非监督归一化方法的MinMax和Sum。结果直接发送到发起查询的对等代理,而无需使用代理代理。Java代理开发框架(JADE)用于实现代理,并且为了进行实验,扩展了TERRIER(TERabyte RetRIEveR)并用作搜索引擎来检索文本检索会议(TREC)集合数据集,特别是TREC-6。发起查询的对等代理逐渐收集来自其他对等代理的结果,对其进行规范化和合并,然后继续进行重新排名。对于归一化,使用非监督归一化方法的MinMax和Sum。结果直接发送到发起查询的对等代理,而无需使用代理代理。Java代理开发框架(JADE)用于实现代理,并且为了进行实验,扩展了TERRIER(TERabyte RetRIEveR)并用作搜索引擎来检索文本检索会议(TREC)集合数据集,特别是TREC-6。发起查询的对等代理逐渐收集来自其他对等代理的结果,对其进行规范化和合并,然后继续进行重新排名。对于归一化,使用非监督归一化方法的MinMax和Sum。扩展了TERRIER(TB级RetRIEveR),并用作搜索引擎来检索文本检索会议(TREC)集合数据集,特别是TREC-6。发起查询的对等代理逐渐收集来自其他对等代理的结果,对其进行规范化和合并,然后继续进行重新排名。对于归一化,使用非监督归一化方法的MinMax和Sum。扩展了TERRIER(兆字节RetRIEveR),并用作搜索引擎来检索文本检索会议(TREC)集合数据集,特别是TREC-6。发起查询的对等代理逐渐收集来自其他对等代理的结果,对其进行规范化和合并,然后继续进行重新排名。对于归一化,使用非监督归一化方法的MinMax和Sum。
