基于用户自然标注的TF-IDF辅助标引算法及实证研究

[目的/意义] 从用户角度出发,研究基于用户自然标注的TF-IDF辅助标引算法。[方法/过程] 首先以核心期刊论文中作者标注的关键词和分类号为源数据,通过对关键词词频进行统计,使用TF-IDF算法构建用户标注词表、形成标引知识库,然后通过IK Analyzer分词软件对待标引的科技项目数据进行切词和停用词处理,进而使用TF-IDF算法和位置加权算法提取科技项目数据的特征词,最终实现对科技项目数据进行关键词和分类的同步标引。[结果/结论] 实验结果表明,机标关键词与人标关键词的相似比在60%以上的科技项目数据占总数的68.1%,机标分类号与人标分类号前三位一致的占总数的83.9%,结果表明基于用户自然标注数据并采用TF-IDF算法在关键词和分类标引方面是可行的。     

Does Physical Activity Enhance Learning Performance?: Learning Effectiveness of Game-based Experiential Learning for University Library Instruction

This paper reports research results of the proposed experiential learning using a game-based educational material. The educational material was an application running on a mobile device and was supported for learners to study university library instruction. During the experiential learning, the learners answered several quizzes provided from the educational material. The quizzes were including experiential contents such as actually to find an academic journal or to reserve a learning room. In order to evaluate learning effectiveness of the experiential learning, this research made a comparative experiment. The experimental group used the educational material and the control group used another educational material of e-learning (non-experiential) but the contents was almost same as the contents of the experiential learning. The comparative experiment took several evaluation elements such as pre-/post-test scores, delayed-test scores and learning motivation scores based on IMMS of ARCS model. The experimental results revealed that experiential learning was superior for the several elements of these metrics. This research, furthermore, analyzed learner's operation data to the educational material and learner's behavior data during the learning in the experimental group. The analyzing results showed three types of the learning behaviors and indicated that an instructor needs to adopt suitable instructional design to each type to bring superior learning effectiveness.     

If we built it,would they come? Creating instruction videos with promotion in mind

This article reports on a video project done in an academic library where faculty were included in the production and marketing of the library instruction videos. The videos allowed the librarian to provide a shorter presentation and spend most of her time working individually with each student. The results showed that 97% of the students watched the videos and were able to benefit from the content. The implementation of the videos was a success due to the collaboration of the professors teaching the three courses and the buy-in of the course coordinator; both factors were essential in the success of the video project.     

Managing a Biomedical Library’s Instruction Program: Redefining Scope

The National Institutes of Health (NIH) library instruction program provides training services to staff, clinicians, and researchers across NIH and several Department of Health and Human Services (HHS) operating divisions. The audience, training needs, and training topics are diverse and constantly changing. The NIH library has developed several new services and class topics to meet the needs of its NIH and HHS communities. Context, strategies, and future directions for the NIH library instruction program are described.     

Alexa,Siri, Cortana,and More: An Introduction to Voice Assistants

Voice assistants are software agents that can interpret human speech and respond via synthesized voices. Apple’s Siri, Amazon’s Alexa, Microsoft’s Cortana, and Google’s Assistant are the most popular voice assistants and are embedded in smartphones or dedicated home speakers. Users can ask their assistants questions, control home automation devices and media playback via voice, and manage other basic tasks such as email, to-do lists, and calendars with verbal commands. This column will explore the basic workings and common features of today’s voice assistants. It will also discuss some of the privacy and security issues inherent to voice assistants and some potential future uses for these devices. As voice assistants become more widely used, librarians will want to be familiar with their operation and perhaps consider them as a means to deliver library services and materials.
