Sentiment analysis often relies on a semantic orientation lexicon of positive and negative words. A number of approaches have been proposed for creating such lexicons, but they tend to be computationally expensive, and usually rely on significant manual annotation and large corpora. Most of these methods use WordNet. In contrast, we propose a simple approach to generate a high-coverage semantic orientation lexicon, which includes both individual words and multi-word expressions, using only a Roget-like thesaurus and a handful of affixes. Further, the lexicon has properties that support the Polyanna Hypothesis. Using the General Inquirer as gold standard, we show that our lexicon has 14 percentage points more correct entries than the leading WordNet-based high-coverage lexicon (SentiWordNet). In an extrinsic evaluation, we obtain significantly higher performance in determining phrase polarity using our thesaurus-based lexicon than with any other. Additionally, we explore the use of visualization techniques to gain insight into the our algorithm beyond the evaluations mentioned above. © 2009 ACL and AFNLP.

Journal of information and Computational Science 2008年第5期5卷 2071-2076页

作者： Ji, Lianen Lu, You Zhang, Fengjun Department of Computer Science and Technology China University of Petroleum Beijing 102249 China Laboratory of Human-Computer Interaction and Intelligent Information Processing Institute of Software Chinese Academy of Sciences Beijing 100080 China

This paper presents a novel 3D interactive system for simulation and visualization of the human jaw motion. Based on the visual tracking technique, teeth plaster cast and marker cards is used for manipulating virtual teeth model and controlling the simulation of jaw motion. Through introducing their interactive semantic attributes, these physical interface elements are classified into various interaction types. Furthermore, various interaction tasks and techniques are seamlessly merged into a uniform interface framework, which integrates physical space with virtual space together. This innovative 3D interface can effectively exploit the dentist's existing skills and provide more intuitive and natural 3D interaction techniques than traditional ones. 1548-7741/Copyright © 2008 Binary information Press October 2008.

本文介绍了一种基于单目视觉的肤色干扰下的变形手势跟踪方法。根据跟踪过程中所用到的基本手势特征，提出了一种基于PGH(成对几何直方图)的静态手势识别方法。为了解决跟踪过程中的肤色干扰问题，实现了基于Kalman滤波器的手势预测跟踪。为了解决跟踪过程中的初始化问题，提出了一种基于层次结构的跟踪初始化解决方案。实验结果表明，该方法能够在肤色干扰的情况下有效地对变形手势进行跟踪，并能够满足基于视觉的实时人机交互的要求。

Wide-Spread deployment for interactive information visualization is difficult. Non-Specialist users need a general development method and a toolkit to support the generic data structures suited to tree, network and multi-dimensional data, special visualization techniques and interaction techniques, and well-known generic information tasks. This paper presents a model driven development method for interactive information visualization. First, an interactive information visualization interface model (IIVM) is proposed. Then, the development method for interactive information visualization based on IIVM is presented. The Daisy toolkit is introduced, which includes Daisy model builder, Daisy IIV generator and runtime framework with Daisy library. Finally, an application example is given. Experimental results show that Daisy can provide a general solution for development for interactive information visualization.

To improve existing social bookmarking systems and to design new ones, researchers and practitioners need to understand how to evaluate tagging behavior. In this paper, we analyze over two years of data from CiteULike, a social bookmarking system for tagging academic papers. We propose six tag metrics-tag growth, tag reuse, tag non-obviousness, tag discrimination, tag frequency, and tag patterns-to understand the characteristics of a social bookmarking system. Using these metrics, we suggest possible design heuristics to implement a social bookmarking system for CiteSeer, a popular online scholarly digital library for computer science. We believe that these metrics and design heuristics can be applied to social bookmarking systems in other domains. © 2007 ACM.

Approach to tracking deformable hand gesture for real-time interaction

引用

Ruan Jian Xue Bao/Journal of Software 2007年第10期18卷 2423-2433页

The tracking of deformable hand gesture is a very important task in vision-based HCI (human-computer interaction) research. A novel real-time tracking approach is proposed to capture the motion of deformable hand gesture with single camera. The proposed approach uses a set of 2D hand models in place of high-dimensional 3D model. It achieves auto-initialization by firstly using Bayesian classifier to do posture recognition, and then locating fingers and fingertips to fit image features to recognized posture. It solves the problem of interference among fingers during tracking successfully by the integration of K-means clustering and particle filter. Moreover, a state checking process is embedded into tracking method, and it realizes resumption from tracking failure and update of hand models automatically. Experimental results show that the proposed method can achieve continuous real-time tracking of deformable hand gesture with high precision, and thus it can meet the requirements from real-time vision-based human-computer interaction.

As technologies are rapidly evolving in the area of storage, recognition and displays, the vision of multi-modal interaction is positioning the human needs central to pervasive access to services. Users expect better looking interfaces that are also easy to use to improve high efficiency and productivity and to focus on task itself instead of tools as providing the invisibility in pervasive computing. However, it is hard to obtain the right service at the right time naturally in the multimedia environment based on current interaction approaches. In this paper, we propose a framework for multi-modal interaction which offers the sketch and speech interactive models without limitation of the diversity and richness of the provided services in the pervasive computing environment. Furthermore, it is applied to describe sample application and shows how it is used to create a new interface with high performance

Efficient digital ink multi-dimension data coding algorithm

Ruan Jian Xue Bao/Journal of Software 2006年第9期17卷 1860-1866页

作者： Li, Jun-Feng Dai, Guo-Zhong Human Computer Interaction and Intelligent Information Processing Laboratory Institute of Software Chinese Academy of Sciences Beijing 100080 China

An efficient digital ink data coding algorithm IWPHSP (integer wavelet packet based hierarchical set partitioned) is proposed in this paper. The algorithm compresses digital ink multi-dimension data losslessly using three approaches: integer wavelet packet transform, hierarchical set partitioned, significant bits combination code and fast adaptive arithmetic code. The experiments show that the IWPHSP algorithm is efficient.
