用户专利文献阅读兴趣及其拓扑结构研究

Research on Readers' Interests in Patent Literature and Its Topology Representation

[目的/意义]通过挖掘用户对专利文献中不同要素的兴趣情况及各要素之间的兴趣相互关系程度,揭示用户对专利文献各部分的关注点或兴趣所在。[方法/过程]以Tobii T60XL眼动仪为工具,邀请26名视力正常从事科研的高校教师和研究生进行实验,记录其阅读专利文献的行为,取其中的有效数据进行研究。具体做法为:针对专利文献的特有编排结构,将每个专利文献划分为12个兴趣区即12个要素,给合用户阅读时的眼动行为、测前问卷、测后RTA访谈进行分析。根据某个要素在所有受测者范围内的访问时间、注视次数、瞳孔直径缩放比3个指标,计算各要素兴趣度;从回视次数出发,得到各兴趣区回视次数的关系矩阵。[结果/结论]构建各要素间的用户兴趣拓扑结构,实验发现:用户阅读兴趣在专利文献摘要、独权和从权之间呈现强三角关系,这3部分是最感兴趣的关联区域,同时用户也高度关注专利的具体技术方案的详细描述部分。

[ Purpose/significance ] By analysis of participants＇ interests and the interrelated interests between areas of interest （AOIs）, we reveal the reader＇s attention or interest in the various parts of the patent literature. [ Method/ process ] With the Tobii T60XL eye tracker as a tool, this paper attempted to carry out an experimental study by obtaining data from the reading of patent literature. The study considered twenty - six participants mainly university teachers and graduate students with normal vision who are actively engaged in scientific research. For the unique layout structure of patent literature, each patent literature was divided into twelve areas AOIs, based on the participants＇ eye movement behavior in patent reading, pre - session interview script and post - session retrospective think aloud （RTA） interviews. The users＇ interest per element and the interrelated interests between elements were computed quantitatively. Interestingness of the element was calculated by eye tracking metrics of relative visit duration, relative fixation count and pupil diameter scaling. The relation matrix was obtained from the regression out count. [ Result/conclusion] The topology of elements was constructed with respect to participants＇ interests. The abstract, independent and dependent claims are the associated regions which were of most interest to scientific researchers, forming a strong triangular relationship. Users were also much concerned about the detailed descriptions of specific technology solutions.
