ACA,Author Co-citation Analysis(ACA)is an important and effective research approach in literature analysis.This paper mapped the intellectual structure of recommendation system studies using author co-citation analysis.In this paper,Web of Science database was used as the data source to filter out the set of core authors from the research articles in 1997-2014.This paper calculated these authors' co-citation matrix and transformed it to Pearson correlation coefficient matrix.Furthermore,the results were then processed by using factor analysis,cluster analysis and multidimensional scaling analysis.The intellectual structure of recommendation system studies was finally mapped.The study showed that recommendation system was currently in rapid development period,and the number of scholars and research scope were expanding rapidly.Collaborative filtering algorithm was the most critical topic in this field.Personalized recommendation,content-based recommendation algorithm,and recommendation algorithm based on data mining were the hotspots in this field.

The paper selected 32 individual blogs in the LIS blogosphere as an example,used five indicators(post number,total number of visits,the heat value of the degree of centrality,betweenness centrality degree),and obtained an empirical evaluation of the performance of LIS blog using Ucinet software for social network analysis and using SPSS for cluster analysis.There is the use of social network analysis indicators and some traditional performance indicators to evaluate the blog.In the future,adding other aspects of blogs such as the content,the use in evaluating the blogs,the paper can make the best use of comprehensive evaluation combined with subjective evaluation and automatic evaluation.

Many scholars use RSI,AI,RCR and Specialization Intensity index to evaluate research institutes' research performance. In this paper,it first provided an overview of a number of source normalization approaches,and then compared the advantage and disadvantage of these indexes.The results showed that different scientific fields had different citation practices.Citation-based bibliometric indicators need to normalize for such differences between fields in order to allow for meaningful between-field comparisons of citation impact.
