Online reputation systems are commonly used by e-commerce providers nowadays. In order to generate an objective ranking of online items’ quality according to users’ ratings, many sophisticated algorithms have been proposed in the literature. In this paper, instead of proposing new algorithms we focus on a more fundamental problem: the rating projection. The basic idea is that even though the ra...

Trust relationships between users in various online communities are notoriously hard to model for computer scientists. It can be easily verified that trying to infer trust based on the social network alone is often inefficient. Therefore, the avenue we explore is applying Data Mining algorithms to unearth latent relationships and patterns from background data. In this paper, we focus on a case ...

Online karaoke allows users to practice singing and distribute recordings. Different from traditional music recommendation, online karaoke need to consider users’ vocal competence besides their tastes. In this paper, we develop a karaoke recommender system by taking into account vocal competence. Alone this line, we propose a joint modeling method named MKLA by adopting bregman divergence as th...

While recent research has demonstrated the impact of online product ratings and reviews on product sales, we still have a limited understanding of the individual’s decision to contribute these opinions. In this research, we empirically model the individual’s decision to provide a product rating and investigate factors that influence this decision. Specifically, we consider how previously posted...

This paper o ers a systematic exploration of online feedback mechanism design issues in trading environments with imperfect monitoring of a seller's e ort level and two possible transaction outcomes (corresponding to high and low quality respectively), one of which has no value to buyers. The objective of feedback mechanisms in such settings is to induce sellers to exert high e ort and, therefo...

The internet has made it possible for online feedback forums (or reputation mechanisms) to become an important channel for Word-of-mouth regarding products, services or other types of commercial interactions. Numerous empirical studies (Houser and Wooders, 2006; Melnik and Alm, 2002; Kalyanam and McIntyre, 2001; Dellarocas et al., 2006) show that buyers seriously consider online feedback when m...

In online markets, Word-of-Mouth (WOM) plays a very important role in shoppers’ online purchasing decisions, especially for experience goods. Hotels, as a form of service product, are intangible and cannot be evaluated before consumption, which makes WOM even more important. Several studies focus on the influence of online WOM on business performance. However, little attention has so far been p...

Academic studies offer a generally positive portrait of the effect of customer relationship management (CRM) on firm performance, but practitioners question its value. The authors argue that a firm’s strategic commitments may be an overlooked organizational factor that influences the rewards for a firm’s investments in CRM. Using the context of online retailing, the authors consider the effects...
