Abstract

The invention discloses a topic discovering system based on community text data. The system includes a mobile-terminal service system and a server-side system; the mobile-terminal service system includes a community-text-data uploading module and is responsible for acquisition, extraction and uploading of the community text data, and the mobile-terminal service system receives the acquired community text data, extracts the types of the community text data and sends the community-text-data types to a data preprocessing module of the server-side system; the community-text-data types include a TXT format, an HTML format and an XML format; the server-side system includes the data preprocessing module, a vector-quantity extracting module, a hot-topic extracting module, a data visualization module and a data managing and storing module; the system enables community residents, community service workers and urban inspectors to participate in community management, the work efficiency is improved, and high-efficiency service is provided for the realization of community intelligent management.

Description

technical field [0001] The invention relates to a topic discovery system and method based on community text data, belonging to the field of computer and network technology applications. Background technique [0002] With the rapid construction and development of urban informatization and the rapid progress of the national economy, many problems such as population management, urban transportation, environmental protection, and social security have been brought about in the rapid urbanization construction, which have hindered the pace of urban development. Community construction is the foundation of urban construction, and improving the quality of community services is directly related to the happiness index of community residents in their daily lives. How to enable community residents to truly enjoy the dividends brought by smart cities is the primary task of community construction, so it is necessary to make full use of the data generated by the community. [0003] In-depth...
