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.
