In order to provide synchronous map service based on message semantics in instant communication software, this paper proposes a technical solution, basically a comprehensive combination of Chinese text segmentation, pattern recognition, and image-text integrated service. A case study based on actual WeChat communication messages is carried out to verify the technical solution, which shows that the proposed solution is both feasible and practically effective. The synchronous message semantics-based image-text integrated service provided by the case study improves the user experience very well.
