Brief information about Link Prediction
Link prediction is a crucial technique in the field of network science that involves anticipating the future connections between nodes within a network. The methodology is widely applied in social networks, biological networks, transportation networks, and web pages. It’s not only used to understand the inherent structure of a network but also for predicting future relationships, recommending products, and identifying missing links.
The History of the Origin of Link Prediction and the First Mention of It
Link prediction’s history traces back to the early studies of graph theory in the late 20th century. The technique started to gain prominence with the growth of online social networks and e-commerce platforms. The first systematic research in link prediction was conducted by Liben-Nowell and Kleinberg in 2003, where they analyzed the co-authorship network to predict future collaboration.
Detailed Information about Link Prediction: Expanding the Topic Link Prediction
Link prediction focuses on predicting or identifying potential edges in a network that might occur in the future or might be missing from incomplete data. The process involves the following stages:
- Feature Extraction: Extracting various topological features that might influence link formation.
