Abstract. Agricultural science and technology website is a very important supporter of driving agricultural information and servicing agriculture. An evaluation method is proposed on agricultural science and technology website based on objective data and artificial ratings, using principal component analysis method. Finally the author used the model to evaluate 18 agricultural science and technology websites, and proposed some suggestions on development of agricultural science and technology websites based on the evaluation result which would act as reference to agricultural science and technology website construction. Keywords: Agricultural science and technology website Principal component analysis method Website evaluation
Agricultural science and technology website is an important window of agricultural science and technology departments and relevant units on the Internet to show their own image, also a concentrated expression of service ability and service level and service features, At the same time also as a important carrier of serviceing “three rural” and promoting agricultural informationization. From the current point of view, although the agricultural science and technology website is rich in resources, but the quality is uneven, how to better improve the website construction is a problem urgent need to solve. A Scientific evaluation method, can make the website administrator to complete understanding of the operation of the site, consummate the existing problems, improve the quality of the website. On the basis of the research of the peer, the principal component analysis method is used, exploring a new method of comprehensive evaluating websites.
1 Overview of Website Evaluation Method At present, there are no unified standards and methods for the evaluation of the website. The author consulted a large number of literature data, summarized the following two kinds methods of the evaluation of the website: © IFIP International Federation for Information Processing 2016 Published by Springer International Publishing AG 2016.

(1) web link analysis At present, Link analysis and web impact factor measure related to it are widely used to evaluate the websites. Link analysis through the number of sites are linked to reflect the quality of the site. The evaluation is on the basis that a web site is linked another website is approval and use of this website, and the content of two website is related; the more number of external links of a web site, Explain Its influence is greater. The network impact factor measure is based on the link analysis, reflect the influence of the web site by the size of web impa
