What are the public data sources for data analysis and mining?
UCI is the most classic, but it is also relatively old. The data museum has sprung up recently, which is very commendable. There are also some websites abroad. For example, you can see that KDDCUP has a competition for a specific problem every year, and the data set is also open. In recent years, there are more and more data mining competitions. You can go to Pascal to see your interests. This is the bookmark of the data set website collected by a person above Delicious, which is quite miscellaneous. Maybe you can find what you want (there is much more content in delicious than now), and then look at the specific content, and then look at what data sets are used by relevant scholars. In addition to the abnormal organization like LDC, many other data can be downloaded from the information in the track paper or the information on the author's homepage. Both data mining and data analysis are aimed at a certain field or a certain problem. In fact, it depends on whether there will be an open mind to disclose data in that field. Two years ago, after Mr. hans rosling made a public appeal at TED, many organizations, including the United Nations, released their own data.
