Influence Analysis of emotional behaviors and User Relationships Based on Twitter Data

Tsinghua Science and Technology 2018年第1期23卷 104-113页

作者： Kiichi Tago Qun Jin the Graduate School of Human Sciences Waseda University

One of the main purposes for which people use Twitter is to share emotions with others. Users can easily post a message as a short text when they experience emotions such as pleasure or sadness. Such tweet serves to acquire empathy from followers, and can possibly influence others＇ emotions. In this study, we analyze the influence of emotional behaviors to user relationships based on Twitter data using two dictionaries of emotional words. Emotion scores are calculated via keyword matching. Moreover, we design three experiments with different settings： calculate the average emotion score of a user with random sampling, calculate the average emotion score using all emotional tweets, and calculate the average emotion score using emotional tweets, excluding users of few emotional tweets. We evaluate the influence of emotional behaviors to user relationships through the Brunner-Munzel test. The result shows that a positive user is more active than a negative user in constructing user relationships in a specific condition.

引用

Journal of Tourism and Hospitality Management 2014年第3期2卷 106-113页

作者： Kleanthis K. Katsaros Athanasios N. Tsirikas Sofia-Maria N. Bani Christos S. Nicolaidis University of Macedonia Thessaloniki Greece

The present paper examines the influence of locus of control, involvement, job satisfaction, and organizational commitment on hotel chief executive officers＇（CEOs） tolerance of ambiguity. The research sample consists of 82 Greek hotels＇ CEOs. The first part of this paper analyses their level of locus of control, involvement, job satisfaction, and organizational commitment, in front of the frequent, uncertain, and ambiguous changes in their business environment. In the second part, results of principal component analysis indicate that two factors characterize CEOs＇ involvement, namely, importance and interest. Further, regression results reveal the significant influence of interest, locus of control, and job satisfaction on CEOs＇ tolerance of ambiguity. Finally, this paper discusses the research findings and proposes certain practical implications for enhancing Greek hotel CEOs＇ level of tolerance of ambiguity and thus, their efficiency during change.
