Assessment Of Visibility and Web Impact Factor (WIF) of Food Science & Technology Institutes Websites Based On Webometrics Scales

For the importance of specialized web sites, the purpose of this study is link analysis of food science & technology institutes websites based on webometrics scales to propose a pattern website for National Nutrition & Food Technology Research Institute in Iran. visibility, the web impact factor (WIF), self link and total link of websites of the food science & technology institutes via webometrics has been Studied in this Research. Cluster analysis and Multi- dimentional scales Studied the Main Clusters and Drawing Two- dimentional Map of Website Based On Co-links.

The results indicated that the FOI website has the highest impact factor among the sites research sample with WIF of 72, while the NIFA with %57/41 received the highest number of inlinks having the highest visibility. The Cluster analysis results of the website showed that websites had collaborated in five major clusters in the Web environment but seven website have remained independent. Multi- dimentional analysis map also confirmed the existence of five categories. this study showed that there has been a relation between inlinks with types of presented services and the content of websites.
