讲座摘要:

Social curation platforms help consumers navigate through vast digital content online. Analyzing a large dataset from the popular image curation site Pinterest.com, this research aims to understand: (i) what users’ curation activities reveal about consumer preferences, content characteristics, and brand perceptions; (ii) how to assess the user-content match and predict curation actions; (iii) how well does social curation site facilitate information discovery.

We propose a novel approach with two components. First, we represent social curation using a heterogeneous information network. Images, users, and curation words are represented as nodes, while edges represent curation actions. Second, we leverage heterogeneous network embedding, a recently developed machine learning method, to map the network to lower-dimensional vectors for analysis while preserving its structural and semantic information.

Our proposed approach significantly outperforms prevailing benchmarks on predicting curation actions. It uncovers user interest groups and image clusters with distinct characteristics, characterizes the user-image matching, and generates insights into brand perceptions and opportunities. Furthermore, analysis shows that social curation activities account for 70% of the information content at the site, while algorithm bias is not evident. We are the first to study social curation using an information network approach, and our study provides ready-to-use tools for managers.
