The aim of research is to investigate the influence of
user’s characteristics on their relevance judgment. The research
method was an analytical survey in which 40 masters students and
graduates of Information and Knowledge Sciences formed the
research population. NEO-personality inventory-revised was used to
investigate the population in 5 factors (Extraversion/ Neuroticism/
Openness to experience/ agreeableness/ Conscientiousness).
Relevance judgment was perfomed on 10 first retrieved records in
Google for 5 keywords that had been searched by the research
population and precision was measured.
Findings showed that users’ relevance judgment is not the same
despite the intervening control Extraversion and agreeableness have
positive and significant relationship with relevance judgment and
there is not any significant relationship between Neuroticism,
Openness to experience and Conscientiousness with relevance
judgment. In other words, users with characteristics such as
Extraversion and agreeableness retrieved more related records. In
general, some personal characteristics have influence on relevance
judgment. Library and information managers can improve search
process through providing suitable job conditions and suitable
environment for users to search information in better situations.
