A Study of Evaluation Model of User Satisfaction with Social Network Services
資訊管理研究領域,已由過去探討功能性導向資訊系統,開始逐漸重視娛樂性導向資訊系統的滿意度與使用行為。目前,具有娛樂性導向資訊系統特性之社交網路服務(SNS)也開始受到相當程度的重視。本研究整合期望確認理論、理性行為理論與動機理論建構出一個社交網路服務使用者滿意度評量模式,這個模式包括了確認、主觀規範、認知有用性、認知樂趣、滿意度與持續使用意向等六個構念,實證研究結果顯示,本研究所提出的模式具有良好的可行性與適宜性。研究結果發現,確認、主觀規範、認知有用性、與認知樂趣,為使用者滿意度與持續使用意向的重要因素。本研究主要貢獻為在資訊管理研究領域,較少有研究探討主觀規範與滿意度的關係,本研究填補了資訊管理研究領域文獻對於主觀規範與滿意度之間關係理論的探討與驗證。Research on user satisfaction and behavior has resulted in increased attention being given to hedonic information system in the information systems (IS) literature. Social network services (SNS) with the characteristics of hedonic information systems are attracting increasing attention in the IS domain In this paper, we proposed an evaluation model of user satisfaction with social network services based on the integration of expectation confirmation theory (ECT), the theory of reason action (TRA), and motivation theory. The proposed research model is comprised of six constructs: confirmation, subjective norm, perceived usefulness, perceived enjoyment, satisfaction, and continuance intention. Empirical results show that the proposed model has a good fit in theoretical and practical application. The results revealed that confirmation, perceived enjoyment, and subjective norm are the determinants of user satisfaction and continuance intention. The main research contribution of the study is that little research has been done on understanding the relationship of subjective norm and user satisfaction, this study fill the research gap in the IS literature by exploring and verifying the theoretical relations of subjective norm
Predicting the Role of Temozolomide Drug in Glioma by Integrating Available Genomic Databases and Computational Methods
Cancer is one of the most serious and harmful diseases that threatens humanity. Currently there is no robust treatment which leads to guaranteed cure from cancer. Thus, researchers from various domains are still working hard to identify molecules such as genes and proteins which could be handled and targeted as cancer biomarkers. Various methods have been developed and the research spans wide range of techniques from wet lab testing by biologists to computational methods by computer scientists. The latter research is promising because it greatly reduces the number of molecules as potential biomarkers. This project investigated existing literature data by integrating text mining, as well as gene–gene interactions. Different genes are highlighted in relationship to Glioma and temozolomide
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
A Statistical Approach with Syntactic and Semantic Features for Chinese Textual Entailment
Recognizing Textual Entailment (RTE) is a PASCAL/TAC task in which two text fragments are processed by system to determine whether the meaning of hypothesis is entailed from another text or not. In this paper, we proposed a textual entailment system using a statistical approach that integrates syntactic and semantic techniques for Recognizing Inference in Text (RITE) using the NTCIR-9 RITE task and make a comparison between semantic and syntactic features based on their differences. We thoroughly evaluate our approach using subtasks of the NTCIR-9 RITE. As a result, our system achieved 73.28% accuracy on the Chinese Binary-Class (BC) subtask with NTCIR-9 RITE. Thorough experiments with the text fragments provided by the NTCIR-9 RITE task show that the proposed approach can significantly improve system accuracy.IEEEEI國外國際20120808~20120810電子版YVegas, Nevada, US
Analysis of Identifying Linguistic Phenomena for Recognizing Inference in Text
Recognizing Textual Entailment (RTE) is a task in which two text fragments are processed by system to determine whether the meaning of hypothesis is entailed from another text or not. Although a considerable number of studies have been made on recognizing textual entailment, little is known about the power of linguistic phenomenon for recognizing inference in text. The objective of this paper is to provide a comprehensive analysis of identifying linguistic phenomena for recognizing inference in text (RITE). In this paper, we focus on RITE-VAL System Validation subtask and propose a model by using an analysis of identifying linguistic phenomena for Recognizing Inference in Text (RITE) using the development dataset of NTCIR-11 RITE-VAL subtask. The experimental results suggest that well identified linguistic phenomenon category could enhance the accuracy of textual entailment system.IEEEEI國際20140813~20140815電子版YSan Francisco, California, US
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
