摘要:One of the most discussed concepts in information science is
relevance, a relationship in which one thing has a direct bearing on
another. We assume that people seek out relevant information to
deal with a question or problem, and we design information systems to
identify the most relevant information for any given query. Yet assessing the
relevance of information is far from straightforward in real-life situations.
Several decades of user studies have shown that people use a wide range of
criteria to select one information source over another, such as subject
matter, style, format, novelty, quality and authorship. Furthermore,
perceptions of relevance change from person to person over time and from
one situation to the next. In information seeking, as in yard sales, one man’s
treasure is another man’s trash.
