  2. Object composition - Wikipedia

    en.wikipedia.org/wiki/Object_composition

    Examples includes various kinds of trees, DAGs, and graphs. Each node in a tree may be a branch or leaf; in other words, each node is a tree at the same time when it belongs to another tree. In UML, recursive composition is depicted with an association, aggregation or composition of a class with itself.

  3. Lemmatization - Wikipedia

    en.wikipedia.org/wiki/Lemmatization

    For example, in English, the verb 'to walk' may appear as 'walk', 'walked', 'walks' or 'walking'. The base form, 'walk', that one might look up in a dictionary, is called the lemma for the word. The association of the base form with a part of speech is often called a lexeme of the word. Lemmatization is closely related to stemming.

  4. Cohesion (computer science) - Wikipedia

    en.wikipedia.org/wiki/Cohesion_(computer_science)

    The functionalities embedded in a class, accessed through its methods, have much in common. Methods carry out a small number of related activities, by avoiding coarsely grained or unrelated sets of data. Related methods are in the same source file or otherwise grouped together; for example, in separate files but in the same sub-directory/folder.

  5. Grouped data - Wikipedia

    en.wikipedia.org/wiki/Grouped_data

    Another method of grouping the data is to use some qualitative characteristics instead of numerical intervals. For example, suppose in the above example, there are three types of students: 1) Below normal, if the response time is 5 to 14 seconds, 2) normal if it is between 15 and 24 seconds, and 3) above normal if it is 25 seconds or more, then the grouped data looks like:

  6. Bag-of-words model - Wikipedia

    en.wikipedia.org/wiki/Bag-of-words_model

    The BoW representation of a text removes all word ordering. For example, the BoW representation of "man bites dog" and "dog bites man" are the same, so any algorithm that operates with a BoW representation of text must treat them in the same way. Despite this lack of syntax or grammar, BoW representation is fast and may be sufficient for simple ...

  7. Class (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Class_(computer_programming)

    In object-oriented programming, a class defines the shared aspects of objects created from the class. The capabilities of a class differ between programming languages, but generally the shared aspects consist of state and behavior that are each either associated with a particular object or with all objects of that class.

  8. Associative array - Wikipedia

    en.wikipedia.org/wiki/Associative_array

    This is most commonly implemented in the underlying object model, like .Net or Cocoa, which includes standard functions that convert the internal data into text. The program can create a complete text representation of any group of objects by calling these methods, which are almost always already implemented in the base associative array class ...

  9. Word Association - Wikipedia

    en.wikipedia.org/wiki/Word_association

    Word Association is a common word game involving an exchange of words that are associated together. The game is based on the noun phrase word association, meaning "stimulation of an associative pattern by a word" [1] or "the connection and production of other words in response to a given word, done spontaneously as a game, creative technique, or in a psychiatric evaluation".
