Sellers readily obtain consumer product evaluations from online reviews in order to identify competitive products detail and predict sales. Firstly, we collect review data shopping websites, social media, communities, other platforms competitors with the help of word-frequency cooccurrence technology. We take mobile phones as an example mine analyze competition information. Then, calculate quan...

Ecologists have long been puzzled by the fact that there are so many similar species in nature. Here we show that self-organized clusters of look-a-likes may emerge spontaneously from coevolution of competitors. The explanation is that there are two alternative ways to survive together: being sufficiently different or being sufficiently similar. Using a model based on classical competition theo...

Differences between native and exotic species in competitive ability and susceptibility to herbivores are hypothesized to facilitate coexistence. However, little fieldwork has been conducted to determine whether these differences are present in invaded communities. Here, we experimentally examined whether asymmetries exist between native and exotic plants in a community invaded for over 200 yea...

Ecological stoichiometry and food web theories focus on distinct mechanisms that shape communities. These mechanisms, however, likely interact in ways that neither theory alone addresses. To illustrate, we show how a model that tracks flow of energy and nutrients through two producers and two grazers reveals two indirect, interrelated roles for "neutrally inedible" producers. First, inedible pr...

Web 2.0 technologies present an opportunity for firms to create online communities where users engage in value creation by submitting product reviews, providing feedback, suggesting ideas, and identifying new sources of innovation.
