What is meant by context sensitivity?
A context-sensitive word, phrase or sentence is one which can receive different semantic values (interpretations) when used in different contexts. In particular, a declarative sentence is context sensitive if it can express different propositions when said in different contexts.
What is context-sensitive prompts?
A context-sensitive user interface offers the user options based on the state of the active program. Context sensitivity is ubiquitous in current graphical user interfaces, often in context menus.
What is CSL in TOC?
Context-sensitive Language: The language that can be defined by context-sensitive grammar is called CSL. Union, intersection and concatenation of two context-sensitive languages is context-sensitive.
How do you know if a language is context sensitive?
A language is context sensitive if and only if it can be generated by a noncontracting grammar. That every context-sensitive language can be generated by a noncontracting grammar is immediate, since context-sensitive grammars are, by definition, noncontracting.
Why is context sensitivity important?
A context-sensitive approach allows ADB to understand and predict how our operations may impact this environment and program in a way that maximize benefits and minimize negative impacts.
What is context sensitive grammar with example?
A context-sensitive grammar (CSG) is a formal grammar in which the left-hand sides and right-hand sides of any production rules may be surrounded by a context of terminal and nonterminal symbols.
Is every Decidable language context-sensitive?
Every context sensitive language is decidable – however as the converse is not true, we can consider decidable languages as level 0.5 on the Chomsky hierarchy. If both L and L are recursively enumerable, then L is decidable.
Which model is accepted context sensitive grammar?
Chomsky Classification of Grammars
| Grammar Type | Grammar Accepted | Automaton |
|---|---|---|
| Type 0 | Unrestricted grammar | Turing Machine |
| Type 1 | Context-sensitive grammar | Linear-bounded automaton |
| Type 2 | Context-free grammar | Pushdown automaton |
| Type 3 | Regular grammar | Finite state automaton |
What is context sensitivity in psychology?
The term context sensitivity refers to whether a response is in tune with the provided social cue. To date, we know little about how well patients with persistent pain respond emotionally to changes in the social context, that is, how context (in)sensitive they are and if this is linked to problem severity.
Are all natural languages context-sensitive?
