To compare the similarity between an article and other articles, you can take the following steps. 1. Definition: how to identify the similarities between the two articles? A) There are several identical words or keywords. B) There are several

Through the collection system, we collect a large amount of text data, but there are a lot of duplicate data in the text that affects our analysis of the results. Before analysis, we need to remove duplication of the Data. How can we select and

1. PrefaceIn the process of natural language processing, it often involves how to measure the similarity between two texts, we all know that the text is a high-dimensional semantic space, how to abstract it, so as to be able to stand in the

To this end we need a large number of data scenarios for the deduplication, after the study found that there is a local sensitive hash locally sensitive hash of things, it is said that this thing can reduce the document to hash numbers, the number 22

The previous example of massive data similarity calculation simhash and Hamming distance we introduced the principle of simhash, we should feel the charm of the algorithm. But as the business grows, so does simhash data, and if the day 100w,10 1000w.
