即时通信文本中地理信息提取——以微信为例
Geographical Information Extraction from Instant Communication Messages: A Case Study of WeChat

摘要 提出一套面向即时通信文本中地理信息提取的技术方案, 综合使用文本分词、空间分析匹配与图文一体服务等技术, 实现即时文本中地理信息的分析获取和同步地图服务, 可以在即时通信交流中提供同步的空间信息分析和主动的网络地图服务。以微信为例, 对上述技术方案进行实例验证。验证结果表明, 所提的技术方案正确、合理、可行。研究成果拓宽了 WebGIS/LBS 的应用领域, 增强了即时通信软件的服务能力, 可为相关研究和实践提供有力支持。
Abstract 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.
