    Rather than ruling out further simplification, however, the retraction declared that further reform of the Chinese characters should be done with caution. Today, some second-round simplified characters, while considered non-standard, continue to survive in informal usage. Second Chinese Character Simplification Scheme (Draft), published in May 1977

    In propositional logic, conjunction elimination (also called and elimination, ∧ elimination, [1] or simplification) [2] [3] [4] is a valid immediate inference, argument form and rule of inference which makes the inference that, if the conjunction A and B is true, then A is true, and B is true.

  4. Axiom of reducibility - Wikipedia

    en.wikipedia.org/wiki/Axiom_of_reducibility

    In his 1914 A simplification of the logic of relations, Norbert Wiener removed the need for the axiom of reducibility as applied to relations between two variables x, and y e.g. φ(x,y). He did this by introducing a way to express a relation as a set of ordered pairs: "It will be seen that what we have done is practically to revert to Schröder ...

[6]: 467 In Spanish, there is a sequential constraint, and /s/ clusters cannot occur at the beginning of a word. Due to this constraint, epenthesis of a vowel in a word before ...

  9. Text normalization - Wikipedia

    en.wikipedia.org/wiki/Text_normalization

    Text normalization is the process of transforming text into a single canonical form that it might not have had before. Normalizing text before storing or processing it allows for separation of concerns, since input is guaranteed to be consistent before operations are performed on it.
