15.7 - Holistic Approach to Meme Evoluation in Social Graphs

Project - Summary

The evolution, spread, management and other relevant properties of business critical information in social media are vital for most businesses. Possible scenarios include:

  • Containment: how to isolate harmful or not desired information spread?
  • Intervention: how to counter harmful information?
  • Transmission: how to introduce or infect the graph with new information so that its success can be estimated with reasonable accuracy (e.g., the case of competing memes).

The questions above are the motivation for this project. Our approach to tackle this problem is to view it as a graph connectivity problem. The single most important questions then is how to acquire the graph structure. Social media sites such as Facebook, LinkedIn, Etc. are in possession of such data but it is generally not easily available. Our approach is to estimate an approximation of the graph structure from the data that is available and related to the specific use case of interest. For this we use a similarity based approach. As a result we are not dealing with a social graph but instead a graph structure that may or may not resemble a social graph. The edges between the nodes are defined by the similarity of the content and other behavior of the nodes. The main modality for us is text and for this reason the most important methodological questions are related to multilingual language models and their scalability.
