Abstract: |
The study conducted a user experiment to collect and analyze image queries and their sequences from different perspectives. We found that:1)Most image query reformulations are related to image content; furthermore,specification,generalization,parallel movement and related words are the most four reformulation types; users tend to start from a generation concept and then to specify gradually. 2)There are four basic query reformulation modes and four mixed modes. 3)Web image retrieval process is often self-evolved at users' cognitive level,but not at system interaction level. However,present image search engines may be not ready for supporting image retrieval's evolution. 1 fig. 2 tabs. 7 refs. |
中文摘要: |
通过网络图像检索实验,采集用户进行图像搜索任务时的提问式及其变化序列,并进行小规模实证。通过内容编码和统计分析发现:①图像检索提问调整绝大多数与内容调整有关,缩检、扩检、平移和跟随系统相关搜索词是发生最频繁的四类主要提问调整行为,用户在图像检索时表现出从宽泛检索入手,逐步缩小范围的行为趋向;②就图像提问调整模式而言,有四种基本模式和四种混合模式,各有特点;③网络图像检索的演进性偏于一种自演进,而现有图像检索系统对交互式演进的支持明显不足。图1。表2。参考文献7。 |
