My project needs to import the crawled Coursera data into the database for future work, such as PHPNow that the data has been crawled, the format exists in the folder, the picture belongs to a directory, I am a data rookie, do not know how to design a database to the correct existence of the data in MySQL? (using navicat), I hope you master Liberal enlighten, younger brother grateful!

My project needs to import the crawled
I have climbed the URL of all the courses on Coursera and placed it in the All_url.txt file, about 2000 lines.
Then I want to use these URLs to crawl other information I want, to synthesize a. csv to facilitate the import of the database.
In the following code, I've only written a few things I want to crawl to test for implementation (such as the crawl of the course schedule, and so on, five of the information I need is not written in the code), but a

browsing images developed by the MIT Media Lab, which consists of three subsystems that extract shapes, textures, and face features, each of which can be retrieved based on one of these features. Since there is not yet a feature that can be well modeled on the image, in the latest version of Photobook Foureyes, Picard and other people are also included in the image labeling and retrieval process, the experimental results show that this method is effective for automatic labeling of images.MARSht

The concept of semi-Supervised Learning (semi-supervised learning) is not complex at all, that is, a centralized learning model for training that contains both labeled data and unlabeled data. Semi-Guided Learning is a machine learning method between Guided Learning and unsupervised learning.
In many tasks in the NLP field, it is difficult to obtain labeled data. In particular, training resources such as syntax and semantics often require deep expert knowledge (such as linguistic knowledge) as g
