A Context-aware and Social Graph based Restaurant Recommender System for Mobile Devices, 2012
NTU


With the increasing popularity of mobile devices and mobile networks, people can get a soaring amount of information, anywhere, anytime. How to solve the problem of the current information overload and provide personalized recommendation services is an important research topic. This thesis exploits the check-ins of Facebook Open Graph to design a mobile restaurant recommender system, which is based on collaborative filtering. The system summarizes the group preferences from individual users check-in in order to provide group recommendation services. Furthermore, the system considers social graph and contextual information to enhance the recommendation quality. This contextual information includes location, distance, age, sex index, time of day, weekday, month, number of companion and type of companion. In this thesis, we also proposed a method to evaluate the impact of location and distance context. Our experimental data is collected from the 69 volunteers in Facebook, which includes the 8264 check-ins. These check-ins are contributed by 3928 users in 2691 different restaurants from 2010/8/15 to 2012/4/30. The experimental results reveal that the accuracy of our system can be increased by approximately 38% while suggesting restaurants within the area of 3-5 km radius, compared to the popularity-based recommendation. It means that the proposed system can provide better recommendations than popularity-based recommendations if the user asks for a restaurant suggestion in a larger area.

Information technology — Affective computing user interface (AUI) — Part 1: Model, 2019

ISO/IEC DIS 30150-1


Responsible for managing Dr. Hui Wang and other team members to develop the first international standard for Affective Computing. Affective computing individualizes user experience based on user needs and characteristics to achieve better outcomes. It is important to consider affective characteristics of humans in the design and presentation of human-computer interactions. Affective computing builds a harmonious human-computer environment by enabling computing-based systems to recognize, interpret, and simulate human affects. Affective applications promise new insights into what people are feeling and can better serve their needs. Limitations on affective computing include diverse affective characteristics currently used and the way to interpret and reply to these affective characteristics. A general, standardized and systematic model is needed to facilitate applying affective computing within human-computer interaction regarding usability and accessibility. This document presents a systematically defined model for affective computing user interfaces (AUI) and topics for AUI standardization. This can be important to eliminate obstacles lying between users and computing-based systems, and establish the core and foundation of affective computing user interface and its applications.
