Linking information and people in a social system for academic conferences

This paper investigates the feasibility of maintaining a social information system to support attendees at an academic conference. The main challenge of this work was to create an infrastructure where users’ social activities, such as bookmarking, tagging, and social linking could be used to enhance user navigation and maximize the users’ ability to locate two important types of information in conference settings: presentations to attend and attendees to meet. We developed Conference Navigator 3, a social conference support system that integrates a conference schedule planner with a social linking service. We examined its potential and functions in the context of a medium-scale academic conference. In this paper, we present the design of the system’s socially enabled features and report the results of a conference-based study. Our study demonstrates the feasibility of social information systems for supporting academic conferences. Despite the low number of potential users and the short timeframe in which conferences took place, the usage of the system was high enough to provide sufficient data for social mechanisms. The study shows that most critical social features were highly appreciated and used, and provides direction for further research.     

Research intelligence involving information retrieval – An example of conferences and journals

This paper reports a work that was intended to reveal the connection between topics investigated by conference papers and journal papers. This work selected hundreds of papers in data mining and information retrieval from well-known databases and showed that the topics covered by conference papers in a year often leads to similar topics covered by journal papers in the subsequent year and vice versa. This study used some existing algorithms and combination of these algorithms to proposed a new detective procedure for the researchers to detect the new trend and get the academic intelligence from conferences and journals.The goal of this research is fourfold: First, the research investigates if the conference papers’ themes lead the journal papers’. Second, the research examines how the new research themes can be identified from the conference papers. Third, the research looks at a specific area such as information retrieval and data mining as an illustration. Fourth, the research studies any inconsistencies of the correlation between the conference papers and the journal papers.This study explores the connections between the academic publications. The methodologies of information retrieval and data mining can be exploited to discover the relationships between published papers among all topics. By discovering the connections between conference papers and journal papers, researchers can improve the effectiveness of their research by identifying academic intelligence.This study discusses how conference papers and journal papers are related. The topics of conference papers are identified to determine whether they represent new trend discussed in journal papers. An automatic examination procedure based on information retrieval and data mining is also proposed to minimize the time and human resources required to predict further research developments. This study develops a new procedure and collects a dataset to verify those problems. Analytical results demonstrate that the conference papers submitted to journals papers are similar each year. Conference papers certainly affect the journal papers published over three years. About 87.23% of data points from papers published in 1991–2007 support our assumption. The research is intended to help researchers identify new trend in their research fields, and focus on the urgent topics. This is particularly valuable for new researchers in their field, or those who wish to perform cross-domain studies.     

FGCS ’88

In every aspect, the conference was successful. We achieved the first two objectives of the conference: to publicize our results, and to provide the opportunity for presenting papers and holding discussions. From the viewpoint of international cooperation, the value of the conference is inestimable. We believe that the final objective of learning from the conference and reflecting it in our future research will be satisfied.     

融合领域特征的科技学术会议语义相似性计算方法

针对目前的语义文本相似度计算方法难以准确估计科技学术会议语义相似性的问题,提出了一种融合领域特征的科技学术会议语义相似度计算方法（siamese-BERT semantic similarity calculation algorithm fused with domain feature, SBFD）。通过实体识别和关键词抽取等方式获取会议的领域特征信息,将其作为特征与会议信息共同输入到基于变换器的双向编码器表示网络（bidirectional encoder representations from transformers,BERT）中,采用孪生网络（Siamese Network）的结构解决BERT的各向异性的问题,并对网络的输出进行池化和标准化,利用余弦相似度计算两个会议之间的相似程度。实验结果表明SBFD方法在不同数据集上都取得了较好的效果,斯皮尔曼相关系数有一定程度的提高。     

Real-time emotion retrieval scheme in video with image sequence features

In the current Internet environment, a lot of multimedia information is navigated on the on-line computer systems. Among the multimedia information, video sequence has the most valuable and meaningful influence on human emotions. Therefore, one human’s emotions to see and feel the same video can be different from that of others depending on the person’s mental state. In this research, we propose a new real-time emotion retrieval scheme in video with image sequence features. The features of image sequence consist of color information, key frame extraction, video sound, and optical flow. Each video feature is combined with the weight for the emotion retrieval. The experimental results show the new approach of real-time emotion retrieval in video with the better results compared to the previous studies. The proposed scheme will be applied to the many multimedia fields: movie, computer game, video conference, and so on.

The methodological soundness of requirements engineering papers: a conceptual framework and two case studies

This paper was triggered by concerns about the methodological soundness of many RE papers. We present a conceptual framework that distinguishes design papers from research papers, and show that in this framework, what is called a research paper in RE is often a design paper. We then present and motivate two lists of evaluation criteria, one for research papers and one for design papers. We apply both of these lists to two samples drawn from the set of all submissions to the RE’03 conference. Analysis of these two samples shows that most submissions of the RE’03 conference are design papers, not research papers, and that most design papers present a solution to a problem but neither validate this solution nor investigate the problems that can be solved by this solution. We conclude with a discussion of the soundness of our results and of the possible impact on RE research and practice.

Data generation and representation method for 3D video conferencing using programming by demonstration

Video conferencing provides an environment for multiple users linked on a network to have meetings. Since a large quantity of audio and video data are transferred to multiple users in real time, research into reducing the quantity of data to be transferred has been drawing attention. Such methods extract and transfer only the features of a user from video data and then reconstruct a video conference using virtual humans. The disadvantage of such an approach is that only the positions and features of hands and heads are extracted and reconstructed, whilst the other virtual body parts do not follow the user. In order to enable a virtual human to accurately mimic the entire body of the user in a 3D virtual conference, we examined what features should be extracted to express a user more clearly and how they can be reproduced by a virtual human. This 3D video conferencing estimates the user’s pose by comparing predefined images with a photographed user’s image and generates a virtual human that takes the estimated pose. However, this requires predefining a diverse set of images for pose estimation and, moreover, it is difficult to define behaviors that can express poses correctly. This paper proposes a framework to automatically generate the pose-images used to estimate a user’s pose and the behaviors required to present a user using a virtual human in a 3D video conference. The method for applying this framework to a 3D video conference on the basis of the automatically generated data is also described. In the experiment, the framework proposed in this paper was implemented in a mobile device. The generation process of poses and behaviors of virtual human was verified. Finally, by applying programming by demonstration, we developed a system that can automatically collect the various data necessary for a video conference directly without any prior knowledge of the video conference system.
