What’s in a Hashtag? Content based Prediction of the Spread of Ideas in Microblogging Communities

Oren Tsure and Ari Rappoport demonstrates that the content of an idea (hashtag) plays an important role in its acceptance by the community.

ABSTRACT

Current social media research mainly focuses on temporal trends of the information flow and on the topology of the social graph that facilitates the propagation of information. In this paper we study the effect of the content of the idea on the information propagation. We present an efficient hybrid approach based on a linear regression for predicting the spread of an idea in a given time frame. We show that a combination of content features with temporal and topological features minimizes prediction error.

Our algorithm is evaluated on Twitter hashtags extracted from a dataset of more than 400 million tweets. We analyze the contribution and the limitations of the various feature types to the spread of information, demonstrating that content aspects can be used as strong predictors thus should not be disregarded. We also study the dependencies between global features such as graph topology and content features.

On April 11, 2012 a powerful earthquake of M8.7 was detected off the west coast of northern Sumatra, Indonesia. A tsunami watch was issued across the Indian Ocean region. Soon after, news of the earthquake and tsunami watch started spreading across Twitter.

These visualizations shows how the news of tsunami spread across Twitter. 
We started monitoring for the keyword ‘tsunami’ around 14:49 Malé time.

Twitter users are represented by points (nodes) and relations by lines (edges).

Salience vs. Commitment: Dynamics of Political Hashtags in Russian Twitter

in social media sites, higher levels of mentioning often correlate with higher levels of engagement (e.g., users tweet about a political rally), while false indicators of engagement are rare: if a user wishes to mention a political movement to disagree with it, she will often not use a tag or specific name referring to that movement, but use a variant of it (e.g., a Twitter user who wants Vladimir Putin out of power may use the tag #Putinout instead of #Putin when tweeting about the prime minister and future Russian president).
