  • In the language of C++, a class that is inherited is called a base class. The class that does the inheriting is called a derived class. Therefore, a derived class is a specialized version of a base class. A derived class inherits all of the members defined by the base class and adds its own, unique elements. C++ implements inheritance by allowing one class to incorporate another class into its declaration. This is done by specifying a base class when a derived class is declared. Let’s begin with a short example that illustrates several of the key features of inheritance....

  • Inheritance is the practice of passing on property, titles, debts, rights and obligations upon the death of an individual. It represents also to pass a characteristic, genetically. It has long played an important role in human societies. The rules of inheritance differ between societies and have changed over time.

  • This paper shows how DATR, a widely used formal language for lexical knowledge representation, can be used to define an I_TAG lexicon as an inheritance hierarchy with internal lexical rules. A bottom-up featural encoding is used for LTAG trees and this allows lexical rules to be implemented as covariation constraints within feature structures. Such an approach eliminates the considerable redundancy otherwise associated with an LTAG lexicon.

  • Object-oriented programming (OOP), inheritance is a way to establish Is-a relationship between objects.[note 1] It is often confused as a way to reuse the existing code which is not a good practice because inheritance for implementation reuse leads to Tight Coupling. Re-usability of code is achieved through composition

  • A formalism is presented for lexical specification in unification-based grammars which exploits defeasible multiple inheritance to express regularity, subregularity, and exceptions in classifying the properties of words. Such systems are in the general case intractable; the present proposal represents an attempt to reduce complexity while retaining sufficient expressive power for the task at hand. Illustrative examples are given of morphological analyses from English and German.

  • Questioning texts represented in semantic relations I requires the recognition that synonyms, instances, and hyponyms may all satisfy a questioned term. A basic procedure for accomplishing such loose matching using inheritance from a taxonomic organization of the dictionary is defined in analogy with the unification a!gorithm used for theorem proving, and the costs of its application are analyzed. It is concluded tl,at inherit,~nce logic can profitably be ixiclu.'ted in the basic questioning procedure. ...

  • The result, which we call Inheritance G r a m m a r , is a proper superset of DCG and includes many features of PATR-II. Its taxonomic reasoning facilitates semantic type-class represent lexical, syntactic and semantic categories and other feature values. In many formalisms (e.g. DCG and PATR-II), equality is the only operation for symbols; in IG symbols are related in an IS-A hierarchy.

  • I propose a uniform approach to the elimination of redundancy in CCG lexicons, where grammars incorporate inheritance hierarchies of lexical types, defined over a simple, feature-based category description language. The resulting formalism is partially ‘constraint-based’, in that the category notation is interpreted against an underlying set of tree-like feature structures. I argue that this version of CCG subsumes a number of other proposed category notations devised to allow for the construction of more efficient lexicons.

  • Prosodic Inheritance (PI) morphology provides uniform treatment of both concatenative and non-concatenative morphological and phonological generalisations using default inheritance. Models of an extensive range of German Umlaut and Arabic intercalation facts, implemented in DATR, show that the PI approach also covers 'hard cases' more homogeneously and more extensively than previous computational treatments.

  • Substantial efforts have been made in order to cope with disjunctions in constraint based grammar formalisms (e.g. [Kasper, 1987; Maxwell and Kaplan, 1991; DSrre and Eisele, 1990].). This paper describes the roles of disjunctions and inheritance in the use of feature structures and their formal semantics. With the notion of contexts we abstract from the graph structure of feature structures and properly define the search space of alternatives.
