3.1

CQLF module

subcomponent of the CQLF metamodel, defined with reference to a specified data-model characteristic

Note 1 to entry: The CQLF metamodel currently distinguishes three modules within CQLF Level 1, Linear (plain-text, segmentation and simple annotation), and three modules within CQLF Level 2, Complex (hierarchical, dependency and containment).

Note 2 to entry: In 5.3, the containment module is formalized by the concept SpanContainment in order to avoid terminological ambiguity.

[SOURCE:ISO 24623-1:2018, 3.8, modified — “the CQLF metamodel” has replaced “a CQLF level” in order to improve clarity outside the context of ISO 24623-1; Note 2 to entry has been added.]

3.2

functionality

label for a concept in a CQLF ontology (3.15) that represents a family of CQL capabilities (3.12) contributing to the expressive power of a CQL (3.5) , formulated at a general level and linked to one or more CQLF modules (3.1)

3.3

frame

label for a concept in a CQLF ontology (3.15) that represents a typical search need (3.6) of end users (3.7) , understood as one facet of the expressive power of CQLs (3.5)

Note 1 to entry: Most frames arise from the specialization of a functionality (3.2) and/or the combination of multiple functionalities.

3.4

use case

label for a concept in a CQLF ontology (3.15) that represents a concrete instantiation of a frame (3.3) , for which it can be determined unambiguously whether a given query expression (3.8) satisfies the search need (3.6) or not

Note 1 to entry: Use cases are often parameterized, i.e. they contain variable elements. Parameterized use cases are satisfied by parameterized query expressions.

3.5

CQL

corpus query language

formal language designed to retrieve specific information from (large) language data collections, and thereby incorporate certain abstractions over commonly shared data models that make it possible for the end user (3.7) (or user agents) to address parts of those data models

Note 1 to entry: A CQL defines a syntactic notation for query expressions (3.8) and the corresponding search semantics, i.e. an intensional specification of the intended result set. For most current CQLs, semantics are implicitly defined by a particular implementation.

[SOURCE:ISO 24623-1:2018, 3.4, modified — “CQL” has been added as preferred term, “end user” has replaced “user” in the definition and Note 1 to entry has been added.]

3.6

search need

information pattern that an end user (3.7) wants to locate in a corpus, based on the primary data stream and/or simple or complex annotation

3.7

end user

agent who uses a CQL (3.5) to satisfy his or her search needs (3.6)

Note 1 to entry: This can be done via an interactive graphical user interface (GUI), a command-line tool, programmatically via some application programming interface (API) or by a software program developed by the end user.

3.8

query expression

string that is syntactically valid in a given CQL (3.5) and can be executed to return a result set

Note 1 to entry: Query expressions are often parameterized with variable elements. No formal specification of the parameter substitution procedure is attempted, but entries for parameterized query expressions in the ontology are required to include informal descriptions of the range of admissible values and any transformations required.

3.9

parameter

variable element in a query expression (3.8) or in the description of a search need (3.6)

3.10

positive conformance statement

assertion that a given CQL (3.5) supports a given use case (3.4) by means of a query expression (3.8)

3.11

negative conformance statement

assertion that a given CQL (3.5) cannot support a given use case (3.4) , frame (3.3) or functionality (3.2)

Note 1 to entry: Negative conformance is due to technical unavailability of specific capabilities in the respective CQL or limitations on the complexity of query expressions (3.8) .

3.12

CQL capability

capability

corpus query language capability

facility provided by CQLs (3.5) to meet a specific aspect of search needs (3.6)

3.13

layer

totality of concepts at the same level of abstraction in a CQLF ontology (3.15)

3.14

token

non-empty contiguous sequence of graphemes or phonemes in a document

[SOURCE:ISO 24611:2012, 3.21, modified — Note 1 to entry has been deleted.]

3.15

CQLF ontology

ontology for a fine-grained description of the expressive power of CQLs (3.5) in terms of search needs (3.6) , which adheres to the structure specified in this document
