includes not only the academic achievements of the thesis, but also the research results in non-
paper form. 2)We found that the development of open source software innovation has promoted
the creativity in the academic field by research on the impact evaluation of open source software
based on Altmetrics. 3)There is a big gap between the software in the Python community, and
most of the academic influence on the software is still low. The limitation of this paper lies
in the fact that the standard of “academic” software needs to be further refined. We think that
the accuracy of the method of matching the keywords, such as the name and introduction of
the software library, needs to be further improved. Besides, we need to strengthen the impact
of academic software in-depth study in order to draw more comprehensive and scientific
conclusions.

A review on information source selection and an integrated conceptual model
〇a*
WANG Fang〇, ZHANG Xin & ZHAI Yujia
As one of the most important research topics in information seeking field, information source
selection has received much attention from scientific community since the 1960’s. With the rapid
growth of information technique, the increasing information sources are posing a new challenge
for people to get information. Meanwhile, scientists have made many achievements in information
source selection behavior for different kinds of people in the context of various information needs,
tasks and situations. In order to provide a deeper understanding of information source selection,
this paper summarizes the results of related studies and discusses potential extensions for future
research.
The literature search and review is based on the following databases: WileyInter Science,
Elsevier Science Direct, Emerald Insight, Pro Quest Digital Dissertations ＆ Theses, EBSCO
Academic Search Premier, Springer LINK, The ACM Digital Library, Taylor ＆ Francis, IEEE/
IET Electronic Library and China Academic Journal Network Publishing Database. The search
queries are “Information source selection” “information source choice” “information source
preference” and “information source adoption”. The retrieval deadline is March 3rd, 2016. Finally,
we identified 299 English articles and 46 Chinese articles.
This paper consists of four parts: an overview of related research, a review of theoretical
factors, the model construction based on theories, and the discussion of future research. The
first part is a general overview, which finds most studies of information source selection are in
Information Science and Medical Science, while a small amount is distributed in management,
education, communication, sociology, psychology and other fields；the main theoretical basis
includes value comparison (such as Principles of Least Effort, Cost-Benefit Theory, Expectancy-
