A Study of Meme Propagation: Statistics, Rates, Authorities, and Spread
نویسندگان
چکیده
We use the Meme-tracking system to understand how phrases spread across news sources [3]. We have observed how a meme gains momentum and loses popularity, and observed how the category of the meme affects its life. We begin by looking at various statistics from the frequency data to understand differences between the lifetime of memes across subject matter and media source, and look for methods to predict how the shape of the graph will change over time. Additionally, we consider the graph of news sources and directed edges from the sources that are hyperlinked in the original article. Here we find the top authoritative news sources and blogs. Additionally, we built a theoretical example to determine the actual influence network. Finally, we consider a cascade network on this graph to determine whether the SIS model is reasonable to model meme propogration.

Distinguishing between Topical and Non-Topical Information Diffusion Mechanisms in Social Media
A number of recent studies of information diffusion in social media, both empirical and theoretical, have been inspired by viral propagation models derived from epidemiology. These studies model the propagation of memes, i.e., pieces of information, between users in a social network similarly to the way diseases spread in human society. Importantly, one would expect a meme to spread in a social...

متن کاملInheritance of Consumer Behavior: Providing a Model for Improving Banking Services Based on Meme Theory with Emphasis on Ethical Components
Background: Meme is a hereditary theory and an idea, behavior, or method that is transmitted from one person to another through culture. Inheritance theories differ in the degree of adaptation and capability, that is, adaptation to the socio-cultural environment in which they are spread. More adaptable and more capable memes will be more successful in transmitting, spreading to more people, and...
متن کاملAudience Analysis for Competing Memes in Social Media
Existing tools for exploratory analysis of information diffusion in social media focus on the message senders who actively diffuse the meme. We develop a tool for audience analysis, focusing on the people who are passively exposed to the messages, with a special emphasis on competing memes such as propagations and corrections of a rumor. In such competing meme diffusions, important questions in...
متن کاملSample NLPDE and NLODE Social-Media Modeling of Information Transmission for Infectious Diseases: Case Study Ebola
We investigate the spreading of information through Twitter messaging related to the spread of Ebola in western Africa using epidemic based dynamic models. Diffusive spreading leads to NLPDE models and fixed point analysis yields systems of NLODE models. When tweets are mapped as connected nodes in a graph and are treated as a time sequenced Markov chain, TSMC, then by Kurtz’s theorem these spe...
