Customer Generated Images (CGIs) on e-commerce platforms have been widely adopted as a promotional tool to persuade customers into purchase. Despite its prevalent applications, the effect of CGIs on customers' post-purchase satisfaction has not been extensively examined. This study postulates...

Livestream technology is increasingly transforming consumers’ online shopping experience, as it enables streamers to perform real-time product presentation while interacting with a large number of consumers to sell those products. In this research, we address how livestream selling platforms...

Clustering is a powerful unsupervised tool for sentiment analysis from text. However, the clustering results may be affected by any step of the clustering process, such as data pre-processing strategy, term weighting method in Vector Space Model and clustering algorithm. This paper presents the...

The explosion of online user-generated content (UGC) and the development of big data analysis provide a new opportunity and challenge to understand and respond to public opinions in the G2C e-government context. To better understand semantic searching of public comments on an online platform for...

Previous research on the identification of key locations (e.g., home and workplace) for a user largely relies on call detail records (CDRs). Recently, cellular data usage (i.e., mobile internet) is growing rapidly and offers fine-grained insights into various human behavior patterns. In this...

In software defect prediction, predictive models are estimated based on various code attributes to assess the likelihood of software modules containing errors. Many classification methods have been suggested to accomplish this task. However, association based classification methods have not been...

The LaCo 0.7 X 0.3 O 3 (X=Co, Ni, Cu, Ga, Fe) perovskite catalyst was prepared by the sol-gel method, and the effect of the partially substituted catalyst at the B-site for the hydrogenation of CO 2 to methane reaction was studied. XRD, H 2 -TPR, TEM, BET, CO 2 -TPDand XPS technologies were used...

Numerous online information systems (e.g., question and answer (Q&A) forums, citizen science communities, and review websites) rely heavily on volunteer contributions. Managers have used monetary incentives to induce individuals to increase their contribution level. However, monetary incentives...

Mesoporous TiO2-Al2O3 composites with different Ti/Al molar ratios were successfully synthesized via pre-hydrolysis co-precipitation method and the corresponding NiW supported hydrotreating (HDT) catalysts were prepared via incipient wetness co-impregnation method. The effects of Ti modification...
