摘要
搜索引擎已成为用户从互联网获取信息的重要工具。本文在筛选测度评价指标和建立数据采集方法的基础上,以"苹果价格"、"玉米供求"和"奶牛养殖技术"为关键词,对比分析了谷歌、百度和中国搜农在农业领域的应用效果。结果表明:谷歌和百度在搜索功能、搜索结果稳定程度、信息量等方面较中国搜索有一定优势,但在内容的专业化、搜索结果的时效性方面尚较欠缺。中国搜农在农产品价格,以及信息时效性等方面较谷歌、百度有明显优势,且其可视化搜索更是独具特色。
Search engine has already become an important tool for users to obtain information online. Based on selecting some evaluation indexes and identifying the method of data collection, the application effects of Google, Baidu and Nongsou in agriculture domain were compared and analyzed by using ＂apple price＂, ＂corn supply and demand＂, ＂milk cow breeding techniques＂ as keywords. The results showed that Google and Baidu are superior to Nongsou in some aspects, such as the search function, the stability of search results and the information coverage, but inferior in the specialization and time effectiveness. Nougsou has prominent advantages in price searching for agricultural products and obtaining timely information. Furthermore, visible search of Nongsou is quite unique.
