Context A term in Prolog. Definition predicate is a collection of clauses with heads that match each other. For example, a predicate can be made up of a collection of rules and facts that have the same functor and arity, and whose arguments are all variables. Example For example, consider the following program: father(Terah, Abraham). father(Abraham, Isaac). father(Isaac, Jacob). father(Jacob, Judah). ancestor(A,D) :- father(A,D). ancestor(A,D) :- father(F,D), ancestor(A,F). This program contains two predicates: father/2 and ancestor/2. The father/2 predicate consists of four facts, while the ancestor/2 predicate consists of two rules. A predicate can be a mix of facts and rules.

A function whose output is either "true" (1) or "false" (0).

the condition under which a statement is either true or false, thus used to specify conditions under which data is required.

Predicates describe what is true about the application domain. A predicate is identified by its name and number of arguments using the notation name/nargs.

A predicate is a function that determines if a SpatialObject meets a given set of conditions, and returns a BOOLEAN result.(empty)

a boolean function that maps a stimulus history to true or false

a boolean function which is used to determine membership

a boolean-valued function

a collection of one or more clauses

a function or condition that evaluates to true or false

a function or function object that accepts several arguments and returns a boolean, or true/false, result

a function that responds with true or false to a particular question

a function that returns a boolean value, i

a function that returns either bool or a type that can be implicitly converted to bool

a function that tests for some condition involving its arguments and returns nil if the condition is false, or some non- nil value if the condition is true

a function which returns a boolean value

a function you use to make a true / false decision

a functor that returns a value convertible to bool (which can be treated as true or false)

a mapping from one or several arguments onto a boolean value (i

a method that returns a Boolean value

an operation whose output is always either the word true or the word false

an SQL expression that evaluates a search condition that is either TRUE, FALSE or UNKNOWN

an unambiguously identifiable Declaration that can be true, false or undecided

a procedure that always returns a Boolean value

a property which is true or false for any

a proposition that has one or more variables or constants that represent objects other than the values true and false

a WHERE clause that qualifies a particular set of rows within the table

A relation identified by functor and arity.

A logical expression which evaluates to TRUE or FALSE, normally to direct the execution path in code.

Collection of clauses with the same functor (name/ arity). If a goal is proved, the system looks for a predicate with the same functor, then used indexing to select candidate clauses and then tries these clauses one-by-one. See also backtracking.

function that returns a generalized boolean as its first value.

A function that that returns a boolean value. Usually, predicates are side-effect free, and are used to test the state of some kind of data structure.

an expression that evaluates to either true or false

A conditional expression that is optionally combined with the logical operators AND and OR to make up the set of conditions in a WHERE or HAVING clause. In SQL, a predicate that evaluates to UNKNOWN is interpreted as FALSE.

In logic, a function whose value is is either `true', or `false'. It specifies a relatioship between arguments. See also Axiom/Theorem, Formula.

A function that returns either a true or false value.

Boolean expression that defines a particular state of shared data; threads wait on a condition variable for shared data to enter the defined state. See also condition variable.

A functor that specifies some relationship existing in the problem domain. For example, is a built-in predicate specifying the relationship of one number being less than another. In contrast, the functor is not (normally used as) a predicate. A predicate is either built-in or is implemented by a procedure.

Syntax that specifies a subset of rows to be returned. Predicates are specified in the WHERE clause of a SQL statement.

A statement you can make about something that can be evaluated later as true or false.

The word or words in a proposition which express what is affirmed of the subject.

Of the three parts of a statement, the predicate, or verb, is the resource, specifically the Property, which defines what the statement means. See also: subject, object.

that part of a sentence which affirms something of the subject of the sentence

part of a sentence that tells what the subject does or is, or what is done to the subject.

one of the two main parts of a sentence or clause, modifying the subject and including the verb, objects, or phrases governed by the verb.

An element of a search condition that expresses or implies a comparison operation.

the verb and the part of the sentence that comes after the verb

traditional and modern grammars often divide sentences so that constituents other than the subject are considered together to form the predicate (e.g. John ( subject) kicked the ball ( predicate)).

related to the two-part analysis of a sentence, in which the predicate refers to all parts of the sentence which are not the subject.

Something that is affirmed or denied of the subject in a logical proposition; the part of the sentence or clause that expresses what is said of the subject.

The part of a sentence that tells what the subject does or has done to it. example: I always forget the difference between a verb and a predicate.

A predicate is a global variable that is normally used in conjunction with a condition variable.

one of the two main constituents of a sentence; the predicate contains the verb and its complements

a logical expression that defines the criteria for filtering the current node-set

a matrix with spaces marked by individual variables , which yields a declarative sentence when the variables are replaced by designators

an elementary sentence with holes in it for object terms

an expression in language that can be combined with a singular referring term to yield a sentence (for example, 'is red')

an expression that filters nodes selected by the node test

an XPath expression in square brackets that is evaluated for each node selected by the location step

a property or attribute or mode of existence which a given subject may or may not possess

a proposition that can have variables and quantifiers

a proposition that has free variables

a sentence-forming Relation

a special type of Expression that carries the guarantee that the Expression

a truth-valued expression involving tuple component values and their relationships

a verifiable expression about a packet

An expression that identifies a property or attribute that can be ascribed to the thing named. We are using the letters F through O as variables for predicates when describing an argument's form.

what is said about the subject. It comprises a verb, which may stand alone, or the entire verb phrase including complements. Children read. Friends and neighbours stopped by to offer help after the event. Grass is green.

the part of a sentence or clause that expresses what is said of the subject and that usually consists of a verb with or without objects, complements, or adverbial modifiers. The predicate excludes the subject itself, which gives it something in common with answers given by politicians.

Obsolete term for expression.

What is said about the subject or clause

The portion of a clause that is not the subject is the predicate. Example: am going to town.”“Jim ate the sandwich.

The part of a sentence that tells you about or describes the subject.

The verb and its related words in a clause or sentence. The predicate expresses what the subject does, experiences, or is. Birds fly. The partygoers celebrated wildly for a long time.

A logical expression that determines whether or not a set of tracing actions should be executed when a probe fires. Each D program clause may have a predicate associated with it, surrounded by slashes / /.

the part of the sentence which makes a statement about the subject

The full range of argument material of a sentence that follows the subject. The predicate includes the Finite verb along with any of its arguments.

The term 'predicate' in linguistics has two distinct (though related) senses, what we will call the subject-predicate sense and the predicate-argument sense. The subject-predicate sense derives from traditional logic, where propositions are divided into two parts, the subject and the predicate, and the predicate is what is affirmed (or denied) of the subject. In the history of formal logic, this original sense was generalized to include relations missing more than a single argument. In the resulting predicate-argument sense, in linguistics, the term 'predicate' refers to a head that expresses a logical relation. Typically, predicates in this sense are verbs, but other types of heads can function as predicates in this sense as well. The two senses are illustrated in (1) and (2). The predicate is underlined; notice that the two senses can pick out the same expression, as in the (b) examples. Subject-predicate sense: Bill gives money to charity. Bill swims. Predicate-argument sense: Bill gives money to charity. Bill swims. Sheila's criticism of the plan

A predicate expresses what is said of the subject; it includes the verb and any modifiers. The field stretched out lazily toward the horizon.

Each sentence contains (or implies) two parts: a subject and a predicate. The predicate is what is said about the subject.

A basic grammatical division of a sentence. A predicate is the part of the sentence comprising what is said about the subject. The complete predicate consists of the main verb and its auxiliaries (the simple predicate) and any complements and modifiers: W

In formal semantics a predicate is an expression of the semantic type of sets. An equivalent formulation is that they are thought of as indicator functions of sets, i.e. functions from an entity to a truth value.

In traditional grammar, a predicate is one of the two main parts of a sentence (the other being the subject, which the predicate modifies). In current linguistic semantics, a predicate is an expression that can be true of something. Thus, the expressions "is yellow" or "likes broccoli" are true of those things that are yellow or like broccoli, respectively.
