摘要
在Web 2.0的驱动下,伴随着UGC(User Generated Content)的爆炸式增长,出现了一种新形式的地理信息——志愿者地理信息(Volunteered Geography Information,以下简称VGI)。其中点评类VGI提供了传统地理信息难以提供的商户环境、服务质量等信息,从而增强了地理信息对环境的表达能力,为消费者决策提供了重要参考。通过对大众点评网的点评信息进行分析,发现商户实体对点评信息的空间分布起着很大的制约作用,使得点评信息延续了商户不均衡的分布态势。但这种制约并不起决定性作用,点评信息仍然表现出一些区别于商户分布格局的特点。随后通过对不同价位餐馆的点评量进行分析,发现消费者更倾向对平均价格较高的餐馆进行点评,从而可能使得部分低价位的餐馆面临信息缺失的危机。
With the drive of Web2.0 and the explosive growth of UGC （ User Generated Content） , there is a new form geographic information, VGI（ Volunteered Geography Information）. The comment VGI provides information about the business environment and service quality that traditional geographic information is difficult to provide, thus enhancing the ability of geographic information to ex- press the environment, and providing important reference for consumers＇ decision - making. This paper based on the analysis of pub- lic review information, find that the space geography environment plays a very restricted role to review information＇ s spatial distribu- tion, makes comments＇ spatial distribution behaved more imbalances like the distribution itself. But this kind of restriction is not deci- sive, and the comment information still shows some characteristics which are different from the merehant distribution pattern. With the Analysis of the comments on restaurants with different price, we found that consumers tend to comment the restaurant with higher meal price , which may make some low priced restaurant facing the lacking of reviews.
