work task to the experiment. Latin Square was used for the experimental design. During the
experiment,the participants were required to think aloud. The study recruited 48 participants.
CNKI,one of the most popular digital libraries,was selected to be the experimental system.
During the experiment,the participants were required to finish the entry questionnaire,pre-
search questionnaire,post-search questionnaire,and evaluation form. The study used SPSS to
perform Pearson correlation analysis and Stepwise regression analysis. It reveals the factors that
are significantly correlated to users’ evaluation result of digital libraries,including information
authenticity,comprehensiveness of collection,navigational function,and so on,labeled as
“correlated sub-dimension”. It also identifies the factors that could predict users’ evaluation results
of digital libraries,such as information appropriateness,link richness and validity,and rationality
of page layout,and so forth,labeled as “predictive sub-dimension”. Based on the results,the study
develops a theoretical model for evaluating interaction function of digital libraries.
The originality of the study lies in that it identifies different sub-dimensions of each dimension in
the integrated three-dimension model of user-digital library interaction and singles out the critical
factors from those identified by previous studies. Furthermore,it identifies the correlated and
predictive sub-dimensions that affect users’ evaluation results of user-digital library interaction.
The study then develops the theoretical model that could be used to evaluate interaction between
users and digital libraries,as well as inform the interaction design of digital libraries.
The study only analyzes the data collected from the questionnaires and does not examine
the experimental recordings. Also,the study only analyzes participants’ perception of their
interaction with the digital library. In fact,their search performance,such as precision or average
precision,may be also necessary for in-depth analysis. In addition,the study asked the participants
to bring a real work task for the experiment. However,for convenience of data analysis,the study
treats all 48 real work tasks as the same one. This may bias the results. Future studies will analyze
the recordings and further categorize the real work tasks based on their task characteristics for
more robust results.

As a kind of multimedia loved by teenagers and children,flash movies are widely spread on the
Internet and become an indispensible part of the online multimedia information resources. The
research on searching flash movies on the Internet is a non-negligible work. The classical keyword
based method of searching flash movies can not meet the requirements of a user to search a
