Research background and significance Fruit is one of the important components in people's daily diet and plays an important role in maintaining health and preventing diseases. However, as living standards improve and people pay more attention to health, the demand for fruit sales data is also increasing. As one of the largest online shopping platforms in China, Taobao has a large amount of fruit sales data, which contains key information such as fruit varieties, prices, and sales volumes. Therefore, studying how to use Python crawler technology to obtain Taobao fruit sales data, and analyzing and displaying it through data visualization technology is of great significance for understanding the sales situation of the fruit market and predicting market trends.
At present, although some research has focused on the analysis and prediction of fruit sales data, most of the research is limited to traditional data analysis methods and lacks research on visual analysis. Data visualization technology can present data to users graphically, allowing users to understand the data more intuitively and discover hidden patterns and trends. Therefore, designing a Taobao fruit sales data visualization system based on Python crawler technology and data visualization technology is of great research significance for improving the analysis and prediction capabilities of fruit sales data.
Research status at home and abroad In recent years, with the rapid development of data science and artificial intelligence, more and more research has focused on visual analysis of data. At home and abroad, there have been some studies on analyzing and displaying fruit sales data through visualization technology.
In terms of domestic research, Hu Haiyan and others proposed a fruit sales data analysis method based on data mining and visualization. By analyzing the association rules and classification rules in the fruit sales data, they discovered some rules and trends in fruit sales. At the same time, they also use visualization technology to display the analysis results in charts, allowing users to understand the fruit sales data more intuitively.
In terms of foreign research, Hansen et al. proposed an online fruit sales analysis system based on web crawler and data visualization technology. They use Python crawler technology to obtain fruit sales data from different fruit sales websites, and display the data to users in the form of charts through data visualization technology, allowing users to understand the price and sales of fruits more intuitively.
However, current domestic and foreign research still has some shortcomings in the visualization of fruit sales data. First of all, most studies only focus on basic indicators such as price and sales volume of fruit sales, and lack the analysis and display of other important information. Secondly, the way of visualizing data is relatively simple and lacks innovation and diversity. Therefore, this research will design a Taobao fruit sales data visualization system by combining Python crawler technology and Django framework to meet users' needs for fruit sales data analysis and display.
Research Methods and Implementation Steps This research will use the following methods and steps to design and implement the Taobao fruit sales data visualization system:
-
Data collection: Use Python crawler technology to obtain fruit sales data from the Taobao platform. By setting keywords and filtering conditions, you can filter out fruit products that meet the conditions, and obtain key information such as price, sales volume, and evaluation of the products.
-
Data preprocessing: Clean and process the obtained fruit sales data, including removing duplicate data, processing missing values, converting data formats, etc. At the same time, possible outliers are processed to ensure the accuracy and reliability of the data.
-
Data storage: Store the preprocessed fruit sales data in the database for subsequent analysis and display.
-
Data analysis: Analyze fruit sales data through statistical analysis and data mining technology, including statistical description of sales volume, price and other indicators, as well as mining of association rules and classification rules.
-
Data visualization: Use the Django framework and data visualization library to display analysis results to users in the form of a variety of charts, including bar charts, line charts, pie charts, etc. At the same time, interactive charts can also be used to enable users to filter data and switch views according to their own needs.
-
System implementation: Deploy the designed Taobao fruit sales data visualization system to the server to ensure the stability and availability of the system. At the same time, the system’s functions and user experience can be optimized through user feedback and testing.
The above steps will be implemented through the Python programming language and corresponding libraries and frameworks. Through this system, users can understand the Taobao fruit sales situation more intuitively and conveniently, thereby better participating in decision-making and prediction of the fruit market.
