In the article "The Difference and Connection between 'Full-text Search' and 'Search Engine'," we mentioned Chinese word segmentation, and in "An Analysis of the Implementation Principles of Double Array Trie," we discussed the realization of high-efficiency Chinese word segmentation. Now, let's set aside the formulas related to the Double Array Trie and conceptually understand segmentation technology. Since English word segmentation is relatively simpler, we will focus primarily on understanding Chinese word segmentation here.
