With rapid technological developments, product-market boundaries have become more dynamic. Consequently, competition for products and services is emerging outside the product-market boundaries traditionally based on SIC and NAICS classification codes. Identifying these fluid product-market boundaries is critical for firms not only to compete effectively within a market, but also to identify lurking threats and latent opportunities. Extant methods using surveys on consumer perceptions or purchase data will be unable to identify the impact that a brand from outside the boundary may have on brands within a product-market. Newly available big data on social media engagement presents such an opportunity. We propose a deep network representation learning framework to capture latent relationships among thousands of brands and across many categories, using millions of social media users’ brand engagement data. We build a heterogeneous brand-user network and then compress the network into a lower dimensional space using a deep Autoencoder technique. We validate our technique using a novel link-prediction method and visualize the learned representations pictorially. We illustrate how our method can capture the dynamic changes of product market boundaries using two well-known events: the acquisition of Whole Foods by Amazon and the introduction of the Model 3 by Tesla. Joint with Yi Yang and Kunpeng Zhang.
