The longest common substrings of a set of strings can be found by building a generalized suffix tree for the strings, and then finding the deepest internal nodes which have leaf nodes from all the strings in the subtree below it. The figure on the right is the suffix tree for the strings "ABAB", "BABA" and "ABBA", padded with unique string ...
Implementation is based on parity-preserving bit operations (XOR and ADD), multiply, or divide. A necessary adjunct to the hash function is a collision-resolution method that employs an auxiliary data structure like linked lists, or systematic probing of the table to find an empty slot.
Named-entity recognition (NER) (also known as (named) entity identification, entity chunking, and entity extraction) is a subtask of information extraction that seeks to locate and classify named entities mentioned in unstructured text into pre-defined categories such as person names, organizations, locations, medical codes, time expressions, quantities, monetary values, percentages, etc.
Pantos are humorous, slapstick entertainment for the whole family, often featuring men dressed in drag. They are sometimes based on a famous fairy tale or story, like "Cinderella," "Peter Pan," or ...
The simplest operation is taking a substring, a snippet of the string taken at a certain offset (called an "index") from the start or end. There are a number of legacy templates offering this but for new code use {{#invoke:String|sub|string|startIndex|endIndex}}. The indices are one-based (meaning the first is number one), inclusive (meaning ...
From Boeing's turbulence and a catastrophic hurricane, to Donald Trump's election victory, "Sunday Morning" host Jane Pauley looks back at key events of a year that was monumental.
That nuanced, expensive vanilla extract will pop more. It ensures better caramelization — hooray for crispy edges and golden-hued cookies. It results in scooped or drop cookies, ...
Both algorithms are based on dynamic programming but solve different problems. Sellers' algorithm searches approximately for a substring in a text while the algorithm of Wagner and Fischer calculates Levenshtein distance, being appropriate for dictionary fuzzy search only. Online searching techniques have been repeatedly improved.
