Recommendation in STSs can prevent information overload and support users to locate relevant items for interaction. This article applies a Topic-Graph Based Recommendation approach. First, we discover semantics behind tags through topic inferencing with Latent Dirichlet Allocation (LDA). Second, we conduct Graph-Based Recommendation for tags and users. The approach is applied on a real-word representative data sample collected from the Academic Social Networking Site ResearchGate. The widely used Co-occurrence Based Graph Recommendation is implemented as a baseline approach. Our preliminary human evaluation shows that the Topic-Graph Based Recommendation can complement to the Cooccurrence baseline to provide more reliable results. Future studies are provided on leveraging future features and information for recommendation from researcher-generated social media data on a large scale. %@ 978-1-4503-6521-5
