Abstract：Friend recommendation plays an important
role in promoting user experience in online social
networks (OSNs). However, existing studies often
overlook users' fine-grained interests and the
evolving features of those interests, which can lead
to unsuitable recommendations. In particular, some
OSNs, such as online learning communities, have
little work on friend recommendation. To address
this gap, we propose a framework for improving
friend recommendation with fine-grained, evolving
interests. We focus on the online learning community
as an application scenario, which is a special type
of OSN for people to learn courses online. Our
framework, called Learning Partner Recommendation
Framework with Evolution of Fine-grained Interest
(LPRF-E), extracts a sequence of learning interest
tags that change over time. We then explore the time
feature to predict evolving learning interests. We
also recommend learning partners based on
fine-grained interest similarity and refine the
framework with users' social influence. Extensive
experiments on two real datasets validate that our
proposed models achieve high accuracy and can
recommend learning partners with high quality.

Abstract：This research compared the achievement of male and female students who were enrolled in an online univariate statistics course to students enrolled in a traditional face-to-face univariate statistics course. The subjects, 47 graduate students enrolled in univariate statistics classes at a public, comprehensive university, were randomly assigned to groups that used either online instruction or traditional face-to-face instruction. The effects of the independent variables of online univariate statistics instruction versus traditional face-to-face instruction on the dependent variable of statistics achievement were analyzed with a two-way analysis of variance. There was a significant difference between the achievement of students who used online univariate statistics instruction and those who used traditional face-to-face instruction (p = .001). The traditional face-to-face group scored higher with an effect size of 0.979, indicating that, on the average, those who were enrolled in a traditional face-to-face univariate statistics class outperformed 83.4% of those enrolled in the online statistics course. Moreover, females using online instruction outperformed males using online instruction and males enrolled in a traditional face-to-face course scored higher than females, with an effect size of 0.651, indicating that, on the average, those males outperformed 74.22% of the females enrolled in a traditional face-to-face statistics course.

Abstract：We are in the era of big data. Data visualization is a fast-growing area that uses computer-supported, interactive, and visual representation of abstract data to enhance people's exploration and understanding of the data. Human processing efficiency of graphics, images, and visual representations tends to be much higher than with numbers and texts. Visualizations of data enable people to effectively observe, browse, manipulate, study, explore, discover, understand, and interact with them, so as to discover hidden relationships and patterns in the data and help users obtain new insights and make effective decisions. In recent years, display technologies have developed quickly. This process has led to the creation of new interactive systems and platforms with unique affordances. For example, virtual reality (VR) provides highly immersive experiences and richer interactive possibilities and is now increasingly being used in data visualization and exploration. In this talk, I will share our research on the exploration of user performance, behavior, and feedback when exploring visualized data/information when completing visual analytic learning activities. We conducted a series of user studies with single and multiple users across several platforms (i.e., desktop, large displays, mobile tablets, and VR) to explore users’ performance, behaviors, and subjective preferences when using these devices for both single users and multiple users. Our research contributes to a better understanding of the potential effects and benefits that different display and interactive platforms could have on analytical reasoning, learning, and exploratory experiences. The aim of this research is to provide insights and guidelines for the future design and use of data/information visualization technologies for single and multiple users across different platforms.

Abstract：Chinese characters have complex structures. Their writing plays an import role in learning Chinese. Junior international students can use digital pen to record their handwriting as digital ink. Various information can be extracted from the digital ink text, such as text line, Chinese characters, stroke errors, shape normalization. Digital ink is a new media compared with digital image and digital video. It is captured from handwriting and freehand drawing using digital pen. Point samples are captured by digital pens, containing positions, time stamp, and pressures. A stroke is a list of sampling points from pen down and movement to pen up. A list of strokes consists of a digital ink. Digital ink Chinese text are stroke sets, have neither text line, nor Chinese characters. Digital ink Chinese texts written by junior international students contain many information including errors and unnormal issues. It is difficult to recognize them. We proposed some intelligent methods to extract information, such as adaptive segmentation based on statistics analysis, classification using machine learning, stroke matching using Genetic Algorithm, evaluating the normalization for entire characters and their components using knowledge bases. With developing new intelligent methods and collecting more data, more valued information can be extracted.
