Predicting Successful Memes using Network and Community Structure
We investigate the predictability of successful memes using their early
spreading patterns in the underlying social networks. We propose and analyze a
comprehensive set of features and develop an accurate model to predict future
popularity of a meme given its early spreading patterns. Our paper provides the
first comprehensive comparison of existing predictive frameworks. We categorize
our features into three groups: influence of early adopters, community
concentration, and characteristics of adoption time series. We find that
features based on community structure are the most powerful predictors of
future success. We also find that early popularity of a meme is not a good
predictor of its future popularity, contrary to common belief. Our methods
outperform other approaches, particularly in the task of detecting very popular
or unpopular memes.Comment: 10 pages, 6 figures, 2 tables. Proceedings of 8th AAAI Intl. Conf. on

Discovering items with potential popularity on social media
Predicting the future popularity of online content is highly important in
many applications. Preferential attachment phenomena is encountered in scale
free networks.Under it's influece popular items get more popular thereby
resulting in long tailed distribution problem. Consequently, new items which
can be popular (potential ones), are suppressed by the already popular items.
This paper proposes a novel model which is able to identify potential items. It
identifies the potentially popular items by considering the number of links or
ratings it has recieved in recent past along with it's popularity decay. For
obtaining an effecient model we consider only temporal features of the content,
avoiding the cost of extracting other features. We have found that people
follow recent behaviours of their peers. In presence of fit or quality items
already popular items lose it's popularity. Prediction accuracy is measured on
three industrial datasets namely Movielens, Netflix and Facebook wall post.
Experimental results show that compare to state-of-the-art model our model have
better prediction accuracy.Comment: 7 pages in ACM style.7 figures and 1 tabl
