Factors Influencing Emoji Usage in Smartphone Mediated Communications

Emojis have become more and more popular in text-based online communication to express emotions. This indicates a potential to utilize emojis in sentiment analysis and emotion measurements. However, many factors could affect people’s emoji usage and need to be examined. Among them, age, gender, and relationship types may result in different interpretations of the same emoji due to the ambiguity of the iconic expression. In this paper, we aim to explore how these factors may affect the frequency, type, and sentiment of people’s emoji usage in communications. After analyzing 6,821 Wechat chatting messages from 158 participants, we found people between 26-35 had lowest frequency of emoji usage; younger and elder groups showed different sentiment levels for the same emojis; people chose emoji types based on relationships. These findings shed light on how people use emojis as a communication tool.
Serendipity with Music Streaming Services: The Mediating Role of User and Task Characteristics
Ying-Han Chang, Muh-Chyun Tang
National Taiwan University, Taiwan
An experimental study was conducted to test the feasibility of using different dimensions of the construct of “serendipity” to evaluate the performance of two music streaming services, namely Spotify and KKBOX. In particular, the impact of search tasks (goal-oriented vs. exploratory) and users’ psychological traits—the degree of “music involvement” and “openness to novelty”—on system performance was explored. Four dimensions of serendipity, “introducing the unexpected,” “accessibility,” “navigability,” and “enabling connection” were used as the performance criteria along with usability. The study employed a Latin square experimental design, in which 32 participants were asked to perform goal-oriented vs. exploratory tasks alternately with the two music streaming services. The main effects of music involvement were identified for three out of four serendipity dimensions. An interaction effect of tasks and systems on performance was also found. The implications of our results on the evaluation of music discovery tools were discussed.

The development of online payment service enables the charging options for knowledge sharing, and morphs the social Q&A platforms into the knowledge exchange market. In the emerging trilateral payment-based social Q&A platforms, the asker needs to offer a certain amount of consulting fees to the answerer, and may also get monetary reward by the listeners’ accumu-lated micro-payments. Thus, the asker’s pay intention is one of the distinc-tive characteristics compared with the traditional Q&A model. This prelimi-nary paper aims at exploring the influence factors that trigger askers’ pay in-tention, by integrating the social exchange theory and social capital theory into examining the emerging style of trilateral payment-based social Q&A platforms.
Domestic Migrant Workers in Israel: The strength of weak ties
Department of information science, Bar-Ilan University, Israel
Abstract. This paper presents an ongoing exploratory study examining the role that weak ties play in the information behaviour of domestic migrant workers liv-ing in Israel. Weak ties are social acquaintances that provide varied information and social support. The study used the narrative method that allows the researcher to study and understand information behaviours intrinsically related to the life stories of the population studied. The interviews looked for narratives that de-scribed their interactions with different information sources, and the role that weak ties play as sources of information and social support that help them make sense of their lives in Israel. Findings revealed that weak ties fulfilled four func-tions: extending access to information, fostering social interactions with dissimi-lar others, facilitating low-risk discussion of high-risk topics, and fostering a sense of belonging.
