Short Text Topic Modeling to Identify Trends on Wearable Bio-sensors in Different Media Types

The technology and techniques for bio-sensors are rapidly evolving. Accordingly, there is significant business interest to identify upcoming technologies and new targets for the near future. Text information from internet reflects much of the recent information and public interests that help to understand the trend of a certain field. Thus, we utilize Dirichlet process topic modeling on different media sources containing short text (e.g. blogs, news) which is able to self-adapt the learned topic space to the data. We share the observations from the domain experts on the results derived from topic modeling on wearable bio-sensors from multiple media sources over more than eight years. We analyze the topics on wearable devices, forecast and market analysis, and biosensing techniques found from our method.
