Currently, I am doing a search function. Lets say in my database, I have this data: Keyword1 Keyword2 Keyword3 Keysomething Key and the user entered: "Key" as the keyword to search. This is my current query: SELECT * FROM data WHERE ( data_string LIKE '$key%' OR data_string LIKE '%$key%' OR data_string LIKE '%$key' ) Basically, I have 2 questions: How do I sort by (order by) similarity. From above example, I wanted "Key" as my first result. My current result is: Keyword1, Keyword2, Keyword3, Keysomething and Key My SQL query only search by the "data_string" column, what if I want to seach

How to determine character similarity?

问题 I am using the Levenshtein distance to find similar strings after OCR. However, for some strings the edit distance is the same, although the visual appearance is obviously different. For example the string Co will return these matches: CY (1) CZ (1) Ca (1) Considering, that Co is the result from an OCR engine, Ca would be the more likely match than the ones. Therefore, after calculating the Levenshtein distance, I'd like to refine query result by ordering by visual similarity. In order to

From the unix terminal, we can use diff file1 file2 to find the difference between two files. Is there a similar command to show the similarity across 2 files? (many pipes allowed if necessary. Each file contains a line with a string sentence; they are sorted and duplicate lines removed with sort file1 | uniq . file1 : http://pastebin.com/taRcegVn file2 : http://pastebin.com/2fXeMrHQ And the output should output the lines that appears in both files. output : http://pastebin.com/FnjXFshs I am able to use python to do it as such but i think it's a little too much to put into the terminal: x =

问题 I'm being a ASP.NET developer over years but recently I started to work with some PrimeFaces solutions with JSF 2.0. I haven't nothing to complain about it. It is worth emphasizing a few points that did ​​me likes the PrimeFaces : many components, easy to use, fully based on jQuery and jQuery UI (which are very important to me) and very focused on web standards (even more important to me). But there are some cases that I would really want my server-side with ASP.NET . I don't want to start a

问题 This is an NLP problem and I was wondering how I should proceed. How difficult is the problem? Could I replace the word with synonyms and check that the grammar is correct? 回答1: Replacing words with synonyms is probably the first thing to try, but be careful not to miss multiple words expressions and idioms. Also, make sure you choose a synonym with the same part of speech. they look for a good solution < ! > they view/stare/... for a good solution they work hard < ! > they job/task/… hard

I have a dataframe as follows: the shape of the frame is (1510, 1399). The columns represents products, the rows represents the values (0 or 1) assigned by an user for a given product. How can I can compute a jaccard_similarity_score? I created a placeholder dataframe listing product vs. product data_ibs = pd.DataFrame(index=data_g.columns,columns=data_g.columns) I am not sure how to iterate though data_ibs to compute similarities. for i in range(0,len(data_ibs.columns)) : # Loop through the columns for each column for j in range(0,len(data_ibs.columns)) : .........

Text similarity algorithm

问题 I have two subtitles files. I need a function that tells whether they represent the same text, or the similar text Sometimes there are comments like "The wind is blowing... the music is playing" in one file only. But 80% percent of the contents will be the same. The function must return TRUE (files represent the same text). And sometimes there are misspellings like 1 instead of l (one - L ) as here: She 1eft the baggage . Of course, it means function must return TRUE. My comments: The

What is the paper “Oliver [1993]” describing a PHP algorithm to calculate text similarity?

由 Deadly 提交于 2019-11-30 10:59:09
There is a function similar_text() in the PHP library. The documentation ( http://php.net/manual/en/function.similar-text.php ) tells me that "This calculates the similarity between two strings as described in Oliver [1993]." Despite extensive searching, I can't find the paper that "Oliver [1993]" is referring to; nor any candidate for who "Oliver" might be. The PHP source is undocumented. The only other reference to Oliver 1993 is in a forum at http://www.codeguru.com/forum/showthread.php?t=41089 , and I think that information is derived from the PHP documentation. Anyone aware of what this
