Link mining, social network and semantic network construction are data fitting problems for which relevant information content is encoded in language and names. Norbert Wiener [7] noted that those features that distinguish human communication are “...(1) the delicacy and complexity of the code used, and (2) the high degree of arbitrariness of this code.” The semantic aspect of language is conce...

With the rapid growth of the netizen population in China, more and more internet frauds are committed. Many people suffer from internet frauds by losing wealth or other valuable things. To prevent internet frauds, we first need to discover the methods in which internet frauds are conducted. In this paper, we investigate and categorize the internet frauds in China. So far, there are typically si...

Over the last few years, microblogging has gained prominence as a form of personal broadcasting media where information and opinion are mixed together without an established order, usually tightly linked with current reality. Location awareness and promptness provide researchers using the Internet with the opportunity to create "psychological landscapes"--that is, to detect differences and chan...

The Wisdom of Crowds, an innovative theory described in social science, claims that the aggregate decisions made by a group will often be better than those of its individual members if the four fundamental criteria of this theory are satisfied. This theory used for in clustering problems. Previous researches showed that this theory can significantly increase the stability and performance of...

Introduction The creation of high fidelity scenarios for disaster simulation is a major challenge for a number of reasons. First, the maps supplied by existing map providers (e.g., Ordnance Survey,1 TeleAtlas) tend to provide only road or building shapes and do not accurately model open spaces which people use to evacuate buildings, homes, or industrial facilities (e.g. the space around a stadi...

Under certain conditions, groups of people may (collectively) make better judgments than experts. Galton connected this phenomenon to the phrase vox populi in a 1907 paper. Arguably, an example of the phenomenon may be found in recent stabilization of the frequency of antidepressant use, following decades of increases. There is no evidence that a change in physi-cian behaviour has caused this s...

Abstract During the unfolding of a crisis, it is crucial to forecast its severity at an early stage , yet access reliable data often challenging on. The wisdom crowds has been effective forecasting in similar scenarios. We investigated whether initial regional social media reaction emerging COVID-19 pandemic three critically affected countries significant relations with their observed mortality...

A longstanding problem in the social, biological, and computational sciences is to determine how groups of distributed individuals can form intelligent collective judgments. Since Galton's discovery of the "wisdom of crowds" [Galton F (1907) Nature 75:450-451], theories of collective intelligence have suggested that the accuracy of group judgments requires individuals to be either independent, ...
