In this paper, we present a method of hierarchical topic detection from heterogeneous social media contents.
Our method firstly extracts latent features for comparing heterogeneous social media contents based on canonical correlation analysis.
Moreover, we construct a heterogeneous graph that has multiple types of nodes (i.e., heterogeneous social media contents), and hierarchically detect sets of contents with similar topics by analyzing community structure in the constructed heterogeneous graph.
As a result, hierarchical structure of the detected sets of contents is revealed.
Therefore, based on the revealed hierarchical structure, users can easily grasp overview of huge amount of heterogeneous social media contents and efficiently find the desired contents from them.
Experimental results on the real-world dataset that are collected from YouTube and Wikipedia show the effectiveness of our method. |
