Beyond traditional collaborative search: Understanding the effect of awareness on multi-level collaborative information retrieval

Although there has been a great deal of research into Collaborative Information Retrieval (CIR) and Collaborative Information Seeking (CIS), the majority has assumed that team members have the same level of unrestricted access to underlying information. However, observations from different domains (e.g. healthcare, business, etc.) have suggested that collaboration sometimes involves people with differing levels of access to underlying information. This type of scenario has been referred to as Multi-Level Collaborative Information Retrieval (MLCIR). To the best of our knowledge, no studies have been conducted to investigate the effect of awareness, an existing CIR/CIS concept, on MLCIR. To address this gap in current knowledge, we conducted two separate user studies using a total of 5 different collaborative search interfaces and 3 information access scenarios. A number of Information Retrieval (IR), CIS and CIR evaluation metrics, as well as questionnaires were used to compare the interfaces. Design interviews were also conducted after evaluations to obtain qualitative feedback from participants. Results suggested that query properties such as time spent on query, query popularity and query effectiveness could allow users to obtain information about team's search performance and implicitly suggest better queries without disclosing sensitive data. Besides, having access to a history of intersecting viewed, relevant and bookmarked documents could provide similar positive effect as query properties. Also, it was found that being able to easily identify different team members and their actions is important for users in MLCIR. Based on our findings, we provide important design recommendations to help develop new CIR and MLCIR interfaces.     

Meta-Circuit machine: Inferencing human collaborative relationships in heterogeneous information networks

Human collaborative relationship inference is a meaningful task for online social networks and is called link prediction in network science. Real-world networks contain multiple types of interacting components and can be modeled naturally as heterogeneous information networks (HINs). The current link prediction algorithms in HINs fail to effectively extract training samples from snapshots of HINs; moreover, they underutilise the differences between nodes and between meta-paths. Therefore, we propose a meta-circuit machine (MCM) that can learn and fuse node and meta-path features efficiently, and we use these features to inference the collaborative relationships in question-and-answer and bibliographic networks. We first utilise meta-circuit random walks to obtain training samples in which the basic idea is to perform biased meta-path random walks on the input and target network successively and then connect them. Then, a meta-circuit recurrent neural network (mcRNN) is designed for link prediction, which represents each node and meta-path by a dense vector and leverages an RNN to fuse the features of node sequences. Experiments on two real-world networks demonstrate the effectiveness of our framework. This study promotes the investigation of potential evolutionary mechanisms for collaborative relationships and offers practical guidance for designing more effective recommendation systems for online social networks.     

20世纪中后期中国图书馆参考咨询工作术语发展研究

与图书馆的其他业务不同,我国图书馆参考咨询工作的称谓一直不统一。1949年之后,参考咨询工作这一术语逐渐取代了参考工作成为国内图书馆界广为接受的称谓。文章试图从学习苏联图书馆学理论及实践工作经验,咨询工作所占比重增加等不同的侧面,探讨影响参考咨询工作术语发展变化的各种因素。

基于专利视角的京津冀医药制造业协同创新评价研究

京津冀协同发展上升到国家战略,产业协同创新情况到底如何值得深入研究。选取京津冀地区的医药制造业作为研究对象,采用京津冀地区医药制造业1995年～2015年专利方面的数据建立复合系统协同度模型,对区域内部医药制造业各自和整体协同度进行测算评价,研究结果表明：（1）区域内专利指标的序参量呈现逐年上升的趋势,说明专利方面的创新趋于有序;（2）协同创新子系统中专利价值子系统的重要地位逐渐显现;（3）京津冀医药制造业协同创新水平不断提升,但目前整体协同创新程度仍居于中等水平。
