摘要
引入"认知众包"这一概念,以社交媒体数据为信息抓手,以广州市为分析对象,逐级阐释"理论探析—信息提炼—转译分析"的意象特色解析流程:通过意象特色属性与社媒数据的特征拟合,构建场景特色与攻略特色结合的数字化总体城市意象特色体系;以可意象性数字量化为技术主轴,提出众包型意象特色的信息提炼框架,搭建从网络素材到认知信息再到意象要素的提炼途径;将要素频次作为统计归纳的基础,从强度、等级、空间分布等方面对意象特色进行整合剖析,得到广州市三能级交互的意象特色体系.同时,捕捉到意象特色在新方法的促进下形成的变化模式、创新动力和问题体现等情况,构建一个非介入式的公众认可的广州城市特色体系,实现可读、可看、可感知的意象分析再创新.
Abstract
With the introduction of"crowd-sourced cognition"concept,the analysis process of image characteristics by"theoretical analysis,information extraction,translation and analysis"is explained based on social media data information of Guangzhou city.Firstly,the digital overall city image characteristic system which combines the scene characteristic and the guideline characteristic is constructed through the fitting of image characteristics and the characteristics of social media data;then,taking the digital quantification of imagability as the technical backbone,the information extraction framework of crowd sourced image characteristics is proposed and the approach from network materials to cognitive information to image elements is built;finally,the factor frequency is taken as the basis of statistical induction,and the image characteristics are integrated and analyzed from the aspects of intensity,grade,space and contrast,so as to obtain the image characteristics system of three-level interaction in Guangzhou.At the same time,the changes,innovation impetus and prominent problems formed by the image characteristics under the promotion of the new method are captured,and a non-interventional public recognition system of Guangzhou's urban characteristics is created,to realize the re-innovation of image analysis that can be read,seen and perceived.
