【摘要】：随着互联网的快速发展,Web生活服务类信息己逐步渗透到人类的生活中并急剧膨胀。网民数量不断增长、需求更加集中及地理位置密度逐渐增大,都为生活服务类网站的崛起提供了必要条件,但是混乱的网站组织方式会迫使用户陷入“信息超载”及”信息迷航”的困境。采用传统的条目式的Web生活服务信息展示方式,会消耗用户庞大的细节察觉成本,不利于用户构建心理定位,用户获取信息和决策的成本往往较高。为解决此问题,本文从用户角度出发,根据用户需求的特点,分析总结了四种常见的用户需求：单用户单信息需求、单用户多信息需求、多用户单信息需求、多用户多信息需求。接着,根据加权图的相关性质,设计了Web生活服务信息的组织算法,然后结合出行链理论和用信息可视化技术中的Bertin编码原则,设计了Web生活服务信息可视化交互原型,并以团购类Web生活服务信息为例,实现该交互原型设计,验证该原型设计的可行性,交互性及其优势。总体来说,本文的工作主要包含以下几个方面： (1)针对当前网络信息组织存在的不足,提出将传统分类法和基于位置服务结合的可视化组织方式,阐明了本文的研究背景和意义。从网络信息组织分类法、基于位置的服务及可视化三个角度分析了国内外的研究现状。 (2)论述了网络信息组织可视化的理论基础。主要包括出行链理论、移动位置服务两个部分。 (3)论述了生活服务信息的组织方法。分为两个部分：第一部分主要对生活服务信息组织方法进行概述,主要阐述了基于分类、基于位置和基于相对位置的信息组织方式。第二部分主要分析了用户需求模式,分为单用户单信息需求、单用户多信息需求、多用户单信息需求和多用户多信息需求四种模式。 (4)阐述了网站信息组织方式的图论描述和针对不同需求类型的信息组织方式算法。 (5)阐述了信息组织及可视化的实现过程。首先介绍了信息可视化工具—可视化编码,然后设计了可视化交互原型,并以团购网站为例的实现这一原型。
[Abstract]:With the rapid development of the Internet, Web life service information has gradually penetrated into human life and expanded rapidly. Both provide the necessary conditions for the rise of life service sites, but the chaotic organization of websites can force users to fall into the dilemma of "information overload" and "information confusion". In order to solve this problem, the cost of obtaining information and making decisions is often higher. In order to solve this problem, this paper starts from the user's point of view, according to the characteristics of the user's needs. This paper analyzes and summarizes four kinds of common user requirements: single user, single user, single user, multi-user, multi-user and multi-information. Then, according to the relevant properties of weighted graph, the paper analyzes and summarizes four kinds of common user requirements: single user, single information, multi-user, multi-user and multi-information. This paper designs the organization algorithm of Web life service information, then designs a visual interactive prototype of Web life service information based on the travel chain theory and Bertin coding principle in information visualization technology, and takes group purchase Web life service information as an example. Implementation of the interactive prototype design, verify the feasibility of the prototype design, interactivity and its advantages. Overall, the work of this paper mainly includes the following aspects:. 1) aiming at the deficiency of the current network information organization, this paper puts forward a visual organization method which combines the traditional classification method and the location-based service, and expounds the research background and significance of this paper. The status quo of research at home and abroad is analyzed from the point of view of location based service and visualization. 2) the theoretical basis of visualization of network information organization is discussed, which includes travel chain theory and mobile location service. This paper discusses the organization method of life service information. It is divided into two parts: the first part mainly summarizes the organization method of life service information, mainly expounds the classification based on, The second part mainly analyzes the mode of user demand, which is divided into four modes: single user, single user, single user, multi-user, multi-user and multi-user. (4) this paper expounds the graph theory description of website information organization mode and the algorithm of information organization mode according to different demand types. Firstly, the information visualization tool-visual coding is introduced, then the visual interactive prototype is designed, and the group purchase website is taken as an example to realize this prototype.
