【摘要】：搜索引擎的诞生为快速找到目标信息提供了可能，但它仅面向个人。为了提高搜索效率，更全更准更快的找到目标信息，人们在搜索的过程中往往需要协同。本文以提高从分散于互联网的海量信息中获取目标信息的效率、减少信息搜索的重复劳动为目的，设计并实现一种适用于小组协同进行信息获取的工具。主要完成了以下工作： 1.本文首先总结分析了国内外大量协同信息搜索相关研究、考察了多个协同搜索系统、提出了目前研究存在的不足和仍需解决的问题。 2.分析和论述了协同技术信息领域的应用以及影响协同的主要因素。 3.在前两章分研究分析基础上，创新性的提出了六个协同的维度，，并分别对每个维度从两个方面进行了分析论述，从每个维度考察了两种不同的协同，并根据这六个维度开创性的建立了一个全面、普适的协同模型，该模型比较全面的反应了协同搜索系统的特性。这个模型包括协同的意图、协作者地域分布、协调媒介、协同的并发性、协作者关系、协作设备6个维度。 4.在第三章提出模型下，提出了增强型协同信息获取系统—Group Search的原型及其设计目标，并从三个层面即用户界面层，格式化层，算法层分析了各个模块的功能。 5.从GroupSearch系统原型和设计目标出发，分析了构建GroupSearch系统需要考虑的一系列问题、提取了GroupSearch系统的关键技术、分析了这些技术如何解决上述问题。 6.论述了GroupSearch系统的实现，主要包括协同环境的实现和系统本身的实现，系统本身的实现主要介绍了系统形式、客户端实现和服务器端实现。最后，根据上面提出的六个维度对协同搜索系统和GroupSearch系统从理论上做了一个客观的比较，并采取用户实际体验的方式，实际验证了GroupSearch的各项功能。
[Abstract]:The birth of search engine makes it possible to find target information quickly, but it is only for individuals.In order to improve the search efficiency and find the target information more accurately and quickly, people often need to cooperate in the search process.In order to improve the efficiency of obtaining target information from the massive information scattered over the Internet and to reduce the repeated work of information search, this paper designs and implements a tool for group collaborative information acquisition.The following tasks have been completed:1.Firstly, this paper summarizes and analyzes a large number of domestic and foreign collaborative information search related research, investigates several collaborative search systems, and points out the shortcomings of the current research and the problems that still need to be solved.2.This paper analyzes and discusses the application of collaborative technology information field and the main factors affecting collaboration.3.On the basis of the research and analysis of the first two chapters, this paper proposes six dimensions of collaboration innovatively, and analyzes each dimension from two aspects, and examines two different kinds of collaboration from each dimension.According to these six dimensions, a comprehensive and universal collaborative model is established, which reflects the characteristics of collaborative search system.The model includes the intention of collaboration, the geographical distribution of collaborators, the coordination of media, the concurrency of collaboration, the relationship of collaborators, and the six dimensions of collaborative equipment.4.In the third chapter, the prototype of the enhanced collaborative information acquisition system-Group Search and its design goal are proposed, and the functions of each module are analyzed from three levels, namely, the user interface layer, the formatting layer and the algorithm layer.5.Starting from the prototype and design goal of GroupSearch system, this paper analyzes a series of problems that need to be considered in the construction of GroupSearch system, extracts the key technologies of GroupSearch system, and analyzes how these technologies can solve the above problems.6.This paper discusses the realization of GroupSearch system, including the realization of cooperative environment and the realization of the system itself. The realization of the system itself mainly introduces the form of the system, the realization of the client side and the realization of the server side.Finally, according to the six dimensions mentioned above, an objective comparison is made between the cooperative search system and the GroupSearch system in theory, and the functions of GroupSearch are verified by the way of the user's actual experience.
