In recent years, with the widespread and development of the network, informational resource is increasingly becoming hotspot today. It provides the convenience with the character of great quantity, rich content, various types, frequent changes, complicated structure , high transmission speed and sharing degree, etc, but many subscribers have no clear idea what to choose in so many uneven qualities information resources, therefore, it is necessary to appraise them so that users can better take advantage of them and improve their utilizing efficiency.Resources assessment of network information determines the quality of the evaluated targets in the sectors by index system, which results in comprehensively grasp their basic situation. More scientific one will be established by utilizing Delphi method, based on analyzing the relative achievements of the scholars both abroad and domestic and summarizing them. It will be classified and elaborated, trying to be objective and reasonable. It embraces 3 first-grade indexes---information content, organization and utilization, 14 second-grade indexes and 33 third-grade indexes.Fuzzy comprehensive evaluation is one newly emerging and widely adopting assessing methods in recent years. Fuzzy complementary matrix will be set up by explaining the theory of fuzzy hierarchy analysis, basing on the character of information resources in network, consulting the experts in this field, and using 0.1-0.9 rating scale method in this paper. The value of the index of every index to the above one will be offered by changing fuzzy complementary matrix into fuzzy uniform matrix and checking heir consistency by the means of MATLAB software program. Such as in one gateway website, the assessing result will be eventually obtained by expert questionnaire and analyzing the quantify data, which verify the reasonability of this evaluating method.
