The rapidly developed Health 2.0 technology has provide people with more opportunities to conduct online medical consultation than ever before. Understanding contexts within different online medical activities becomes a significant issue to facilitate patients' medical decision making process. As a subcategory of machine learning, neural networks have drawn increasing attentions in natural language processing applications. In this study, we focus on the modeling and analysis of patient-physician-generated data based on an integrated CNN-RNN framework. A CNN-based classifier is designed to extract textural features in the sentence-level, and a RNN-based model is constructed to learn the potential patterns and correlations in a dialog-level. An intelligent recommendation mechanism is then developed to provide patients with automatic clinic guide and pre-diagnosis suggestions in a data-driven way. Experiments based on the collected real world data demonstrate the effectiveness of our proposed model and method for online medical pre-diagnosis support.
