Similarity calculationThe application of string similarity is very extensive, and the algorithm based on Levenshtein Distance is particularly classic, but it is still insufficient in the aspect of universal applicability and accuracy of results. Combined with the Longest Common Subsequence (LCS) and ...
string-similaritySi**无言 上传1.02 MB 文件格式 zip 在爬取新闻并存储到数据库时,需要解决重复新闻的问题。为此,可以采用余弦相似度算法来计算两篇新闻正文的相似度。该算法通过比较两篇文本在向量空间的夹角来衡量它们的相似程度,从而判断是否为重复新闻。首先,将新闻正文进行预处理,如去除停用词、标点符号等,然后...
String Similarity Info Thecomparefunction compares two strings and returns a similarity score It is a custom algorithm so it may not work in all cases, but it was pretty good in tests Therankfunction can be used for search features: it ranks results based on their comparison score using the...
String Similarity A simple, lightweight (~700 bytes minified) string similarity function based on comparing the number of bigrams in common between any two strings. Returns a score between 0 and 1 indicating the strength of the match.Based on the Sørensen–Dice coefficient, this algorithm is ...

两个文档都匹配,但是第一个比第二个有更多的匹配项。 如果我们加入简单的相似度算法(similarity algorithm),计算匹配单词的数目,这样我们就可以说第一个文档比第二个匹配度更高——对于我们的查询具有更多相关性。 但是在我们的倒排索引中还有些问题: "Quick"和"quick"被认为是不同的单词,但是用户可能认为它们是相...
String Similarity Tool This tool uses fuzzy comparisons functions between strings. It is derived from GNU diff and analyze.c. The basic algorithm is described in: "An O(ND) Difference Algorithm and its Variations", Eugene Myers; the basic algorithm was independently discovered as described in:...
