  2. Approximate string matching - Wikipedia

    en.wikipedia.org/wiki/Approximate_string_matching

    The closeness of a match is measured in terms of the number of primitive operations necessary to convert the string into an exact match. This number is called the edit distance between the string and the pattern. The usual primitive operations are: [1] insertion: cot → coat; deletion: coat → cot; substitution: coat → cost

  3. Fuzzy matching (computer-assisted translation) - Wikipedia

    en.wikipedia.org/wiki/Fuzzy_matching_(computer...

    When an exact match cannot be found in the TM database for the text being translated, there is an option to search for a match that is less than exact; the translator sets the threshold of the fuzzy match to a percentage value less than 100%, and the database will then return any matches in its memory corresponding to that percentage.

  4. String-searching algorithm - Wikipedia

    en.wikipedia.org/wiki/String-searching_algorithm

    A simple and inefficient way to see where one string occurs inside another is to check at each index, one by one. First, we see if there is a copy of the needle starting at the first character of the haystack; if not, we look to see if there's a copy of the needle starting at the second character of the haystack, and so forth.

    en.wikipedia.org/wiki/Help:Searching

    Wikipedia uses a powerful search engine, with a search box on every page. The search box will navigate directly to a given page name upon an exact match. But, you can force it to show you other pages that include your search string by including a tilde character ~ anywhere in the query.

  6. Knuth's Algorithm X - Wikipedia

    In other words, the subcollection {B, D, F} is an exact cover, since every element is contained in exactly one of the sets B = {1, 4}, D = {3, 5, 6}, or F = {2, 7}.There are no more selected rows at level 3, thus the algorithm moves to the next branch at level 2…

  7. Boyer–Moore string-search algorithm - Wikipedia

    en.wikipedia.org/wiki/Boyer–Moore_string-search...

    This uses information gleaned during the pre-processing of the pattern in conjunction with suffix match lengths recorded at each match attempt. Storing suffix match lengths requires an additional table equal in size to the text being searched. The Raita algorithm improves the performance of Boyer–Moore–Horspool algorithm. The searching ...

  8. Propensity score matching - Wikipedia

    en.wikipedia.org/wiki/Propensity_score_matching

    Radius matching: all matches within a particular radius are used -- and reused between treatment units. Kernel matching: same as radius matching, except control observations are weighted as a function of the distance between the treatment observation's propesnity score and control match propensity score. One example is the Epanechnikov kernel.

    It provides a bit more flexibility by including variations and additional terms within the search query. This match type covers search terms that include your targeted keyword phrase, along with other words before or after it. When a shopper searches for a keyword phrase containing your targeted phrase and other terms, your ad may appear.
