摘要

当在实验、非交互环境中测量时,最佳匹配信息检索(IR)系统中的查询长度众所周知与IR任务的有效性呈正相关。然而,在可操作的交互式IR系统中,查询长度通常非常短,大约为两到三个单词。我们报告了一项研究,该研究测试了特定的查询引出技术在增加初始搜索者查询长度方面的有效性,并测试了使用该技术引出的查询的有效性,以及交互式IR中查询长度与搜索有效性之间的一般关系。结果表明,特定技术产生的查询比标准的查询引出技术长,该技术确实可用,该技术提高了用户对搜索的满意度,并且查询长度与用户对搜索的满意度呈正相关。

Query length in interactive information retrieval
Query length in best-match information retrieval (IR) systems is well known to be positively related to effectiveness in the IR task, when measured in experimental, non-interactive environments. However, in operational, interactive IR systems, query length is quite typically very short, on the order of two to three words. We report on a study which tested the effectiveness of a particular query elicitation technique in increasing initial searcher query length, and which tested the effectiveness of queries elicited using this technique, and the relationship in general between query length and search effectiveness in interactive IR. Results show that the specific technique results in longer queries than a standard query elicitation technique, that this technique is indeed usable, that the technique results in increased user satisfaction with the search, and that query length is positively correlated with user satisfaction with the search.
