domestically. 3) The research trend includes the weakening and derivation of the knowledge map
research, more interdisciplinary research and application research and more cooperation and
innovation of knowledge creators.
Knowledge map is a fusion of Natural Science and Social Science in the multi-disciplinary field
of research and application, and because of the incompatibilities of Social Science and Natural
Science journal citation data at home and abroad, this study is conducted only based on articles in
the field of Social Science journals. The follow-up study should be expanded to other subjects to
draw more comprehensive results.
This article provides new theoretical research perspectives and data to master the development
trail of knowledge map through summarization of its venation, genre and trend. This article also
can support the library and information academia to promote creative research and implication of
knowledge map, such as research on knowledge organization based on citation analysis, intelligent
aggregation of internet information resource of specific fields, construction of classification system
and evaluation of internet information resource, and so on.
This article has made a comprehensive, integrated, systematical analysis of knowledge map
research at home and abroad and investigated time axis, research focus, schools, core researchers
and organizations, co-research relationship, and revealed relationship between researchers by
computing co-author comprehensive index.

digital reading

With the development of the network and digital technology, the amount of literature increases
rapidly. Meanwhile the reading media is changing and affecting reader’s reading behavior
patterns. Reading is complex information processing, including a series of cognitive understanding
behaviors carried out by readers alternately, such as phonological analysis, morphological analysis,
lexical analysis, syntax analysis, meaning understanding and reasoning. So measuring the cognitive
understanding effects of reading could reflect the reading comprehension ability. Current research
is mainly based on paper books, but digital reading has become the trend today. Mobile phone
is the major reading device and readers enjoy reading news and novels. So processing of digital
reading comprehension is becoming the focus of reading study.
Controlled experiment was designed to find the difference of the cognitive understanding level
between paper reading group and digital reading group. The design of questionnaire is based
on the testing framework of PISA (Program for International Student Assessment). The test
