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.

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

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.

Following the great improvement in interaction devices and software technologies, lots of novel interaction technologies which are based on Post-WIMP user interface are studied. It is crucial that the designer chooses the interaction component or the interactiontechnology properly and efficiently to adapt to the various interaction devices and environments in the user interface designing. According to the analysis of the interaction process and the design level of the Post-WIMP user interface, an interaction-Centered Hierarchical Post-WIMP User Interface Model is presented. It is described and analyzed from the aspects of the user, task, device, behaviors and entity in interaction. Moreover, a Post-WIMP user interface auto-generate tool is designed and implemented based on the model, to help the designers to insert those novel interaction technologies into the system flexibly, and to develop and evaluate the prototype quickly and efficiently. Experiments show that, the model can guide the process of user interface design, the implement of prototype, and the evaluation of the result of design.

Pen-Based user interface software is widely applicable due to its natural and efficient interaction style, whose important characteristics are interaction-centered and individual by user-required. In order to map the intention of users into the designs exactly and efficiently, PUIDM (Pen based User Interfaces software Domain Model) is presented, which is described and analyzed from the aspects of context, component, UI features and architecture, and implemented based on XML. Moreover, a user-centered design process based on the PUIDM is introduced. Experiments show that PUIDM can guide the process of design exactly and efficiently and make the designed software achieve the demand of usability.
