Abstract： [Purpose/significance] Information quality is an important premise for platform to improve competitive advantage and sustainable development. The free and open spirit of academic social networking sites causes obstacles to information quality control. Therefore, it is necessary to optimize and improve information quality through analysis of key elements.[Method/process] Based on the previous research work, an information quality governance decision-making model of academic social networking sites is constructed, which composed by four dimensions of control rules, platform technology, information content and information users; based on the DEMETAL method, each impact strategy is identified and analyzed to determine the key strategies affecting the information quality of academic social networking sites.[Result/conclusion] Through data analysis, five important conclusions are sorted out, two management inspirations and implementation steps are summarized, which can overcome the subjective assumptions in qualitative research and provide practical references for human-computer interaction, quality control and service design of academic social networking sites' platform.

Abstract： [Purpose/significance] Reviewing the research progress of music information seeking is helpful to clarify the characteristics and influencing mechanism of music information seeking, which can lay a foundation for research of non-strictly rational leisure information seeking such as leisure reading and video search, and provide evidence for the construction of personalized music platform. [Method/process] According to the basic analysis framework of "internal demand → influence mechanism → process strategy → technology trend", literature review was conducted from 4 aspects:researches on music information demand, researches on influencing factors of music information seeking, researches on process of music information seeking and researches on technology of music search. [Result/conclusion] In the current research, there are some core problems, for example, the researches on user satisfaction of human-computer interaction are few and the theories and application researches related to music information encounter are not found. The following directions deserve attention in future researches:By integrating interventional research and the unobtrusive research paradigms, the researches will actively explore the problem of human-computer interaction user satisfaction to strengthen the process-oriented user experience; on the basis of S-O-R and other theories, by measuring the specific physical or emotional responses of users in the process of music information seeking, the researches will actively explore the occurrence mechanism and performance of music information encounter; on the basis of tasks, situations, tools and other dimensions, the researches will blend the gamification elements into the online music platform design to stimulate the generation of music information encounter.

Abstract： [Purpose/significance] Compared with single person search, collaborative search is helpful to solve the tasks of complex information needs. Further research on the learning effect of collaborative search team, which has not been clarified in academic circles, will help to explore the antecedents and mechanism of the learning effect, and provide some enlightenment for improving the team's information search ability and cooperative learning ability.[Method/process] Based on the theory of cooperative learning, this study adopted the method of information search experiment to verify the difference of learning effect of collaborative search team under different group size, communication quality and task type level.[Result/conclusion] In the decision-making task scenario, there are significant differences in the team learning effect among 2-person group, 4-person group and 6-person group, and the team learning effect of 4-person group is the best; the quality of intra group communication has a significant impact on the learning effect of collaborative search team; in the context of decision-making task, group size and team communication quality have an interactive effect on team learning.

Abstract：【目的】基于概念格理论探索并提出复用产品分类的产品领域本体构建方法, 对以往复用产品分类的产品领域本体构建方法进行改进。【方法】从产品分类中抽取类、属性及关系, 并对其结构进行合理调整, 基于概念格理论生成形式背景及概念格, 并以此为基础自动生成产品领域本体。【结果】本文方法消除了产品分类本身存在的层级不分明的局限性, 可以解决产品分类定义的属性间的冗余问题, 提升本体的可重用性和可共享性, 并通过可视化的形式呈现了现有和潜在的实体与关系。【局限】仅选取医疗产品构建的一个片段来说明该方法的具体实施方案, 并仅探讨该方法对于eCl@ss 产品分类体系的适用性。【结论】基于概念格构建产品领域本体前需对本体的领域和范围进行明确界定, 依据科学分类原则对类目进行梳理与归类, 在进行本体构建时构建属性词典并定义对象属性, 通过形式背景与概念格的生成自动生成本体。
