[目的/意義]網絡化的科學交流、數字化的出版方式要求革新學者評價方法。以機構知識庫為數據源,探討Altmetrics視角下的學者影響力評價,可以為評價遴選指標、優化模型提供借鑒,也有助于促進機構知識庫建設。[方法/過程]編程獲取樣本機構141位學者的Altmetrics數據和被引數據,分別憑借因子分析、Altmetric.com已有指標、加權賦值法進行基于標準化Altmetrics得分、基于Altmetric Score、基于標準化被引得分的學者排序,并開展學者影響力二維評價,將學者劃分為4種類型。[結果/結論]機構知識庫可以作為學者評價的數據獲取平臺;學者的Altmetrics分值對被引分值高低有一定預見性等。[局限]基于定量數據開展評價,未能對結果進行定性評議。

[Purpose/significance] Both the network scientific communication and digital publishing forms ask for a new method to evaluate scholars' influence. Taking institutional repository as data source,this paper tries to discuss the evaluation of scholars' influence from the perspective of Altmetrics,which could provide references to select evaluation indicators and optimize evaluation model of scholars' influences,as well as promote the construction of institutional repositories. [Method/process]On the basis of obtaining Altmetrics data and cited data of 141 scholars from sample universities through programming,the paper carries out the evaluation of scholars' influence based on standardized Altmetrics score by means of factor analysis,Altmetric Score by means of existing indicators on Altmetric. com and standardized cited score by means of weighted assignment method. The paper carries out a two-dimensional evaluation and divides scholars into four types. [Result/conclusion] Institutional repositories can be used as platforms to acquire the data for evaluating scholars' influence. A scholar's Altmetrics score has certain predictability for his or her cited score. [Limitations]The evaluation is only based on quantitative data and no qualitative assessment is done to test the evaluation results.
