Ding Chuang Tech is short for Xi’an Ding Chuang Electronic Technology Co., Ltd., and is a start-up company taking the development and operation of mobile phone accessories and intelligence peripheral products as the core business. To find new things and new demands is the key to profitability quickly for start-ups, so public opinion monitoring on smart phones and accessories is particularly important.Public opinion system is based on MySQL database management system and developed by Python.The system consists of user configuration module, data crawling module, data extraction module, data analysis module and data storage module.The user configuration module is mainly used for keyword management, category management and early warning management,and the keywords include the main words,or words,filter words and early warning words.Data crawling module drive the focused crawler to achieve the accuracy information,and there are two points to notice, on the one hand to ensure the timeliness and completeness of data, on the other hand to strictly abide by access restriction.Data extraction module is the key to get information from web pages,and the information include the title of article, the text, the published time of article and other data.In this module,we are analyzing the structure of the web page to extract the title and text,and using regular expression to extract the publication time, author, source of information.Data analysis module is used to determine the relevance of the information and the user.Data storage module is the core module of the system,and all modules are required to interact with the data storage in order to realize the function of its own module, so this module should to have high concurrency and stability.The public opinion system tested function combining the needs of Ding Chuang Tech,and the test results show that the system can meet the needs of users to monitor public opinion to obtain information on the timeliness and comprehensiveness.lt has a certain value for use.
