string similarity

In actual projects, similarity calculation is required in many cases. For example, in e-commerce systems, users who like this product often prefer this product, generally, similarity calculation is one of the methods to implement this function,

In the classification clustering algorithm, it is often used to calculate the distance of two input variables (usually the form of eigenvector), that is, the similarity measure. Different similarity measures for the results of the algorithm, some

1. IntroductionThe article "Data Synchronization Algorithm Research" describes how to synchronize data efficiently on the network. The premise is that files A and B are very similar, that is, there is a large amount of identical data between the two.

Similarity Data Detection Algorithms calculate the similarity ([], 1 indicates the same) or distance ([0,), 0 indicates the same) between a given pair of data sequences ), to measure the degree of similarity between data. Similar data detection has

Similarity Data Detection Algorithms calculate the similarity ([], 1 indicates the same) or distance ([0,), 0 indicates the same) between a given pair of data sequences ), to measure the degree of similarity between data. Similar data detection has

Two strings are provided. Three operations are performed: 1. modify a character 2. Add one character 3. delete a character One operation adds 1 to the distance between two strings. through three operations, the two strings are eventually equal, and

The Levenshtein Distance algorithm, also called the edit Distance algorithm, refers to the minimum number of edit operations required between two strings, which are converted from one to the other. permission edits include replacing one character
