Classes

AnnotationProcess G AnnotationProcess Annotation Process
Feature G Feature Feature
Abstract UnitsOfAnnotation and Relations can be described in a more detailed way by the features that are attached to them, e.g., case, number, or aspect. Features are, however, not subject to further annotations (by means of hasFeature), they are thus disjoint from Relations and UnitsOfAnnotation.
SubClass Of
LinguisticAnnotation G LinguisticAnnotation Linguistic Annotation Feature Feature LinguisticAnnotation->Feature hasFeature
Abstract Linguistic annotations pertain to either structural entities (words, tokens, constituents, sentences => UnitOfAnnotation), relations between these (dependency, dominance, coreference, etc. => Relation), or grammatical features attached to these (case, gender, number, agreement, tense, mood, aspect, ... => Feature).
Sub-Classes
Relation G Relation Relation UnitOfAnnotation Unit Of Annotation Relation->UnitOfAnnotation hasTarget Relation->UnitOfAnnotation hasSource
Abstract Between instances of two Categories, a Relation can be established that links these together, e.g., a dominance relation (constituent X is grammatical subject of sentence Y), a dependency relation (token X is a modifier of token Y), a discourse relation (discourse unit X is in contrast to discourse unit Y), an anaphoric relation (referring expression X is coreferent with referring expressing Y), an alignment relation (word X expresses the same meaning as word Y). Note that Relation and UnitOfAnnotation are not disjoint, because in some approaches, establishing a Relation between two concepts entails that a structural entity is formed, consisting of Relation and the Categories connected by the Relation, e.g., in Rhetorical Structure Theory (Mann and Thompson 1987).
SubClass Of
UnitOfAnnotation G UnitOfAnnotation Unit Of Annotation
Abstract A UnitOfAnnotation is a structural entity that can be annotated, e.g., a word, token, constituent, or another types of markable. Word classes, etc., are then modelled as indirect children of UnitOfAnnotation. The division between Features and classes of UnitsOfAnnotation follows conventional standards.

Object Properties

hasFeature G hasFeature hasFeature
Abstract A UnitOfAnnotation or a Relation can carry Features that express annotations attached to them. By convention, (tags that represent) Features can be linked with Feature individuals, as well. Because of this reflexivity, a predicate like hasDegree(positive) allows to retrieve the individual positive as well. (This is necessary if positive represents a tag on its own, rather than being a property of a complex tag.)

Datatype Properties

hasTag G hasTag hasTag
Abstract Assigns a Linguistic Annotation a String representation, e.g., a particular Part of Speech tag, the respective abbreviation of the grammatical cases used in an annotation scheme, etc. implicit semantics: hasTag is to be used if the tag is equal to the string value, otherwise use hasTagContaining, hasTagStartingWith, hasTagEndingWith
Sub-Properties
Domain
hasTagContaining G hasTagContaining hasTagContaining
Abstract As opposed to hasTag proper, the string representation defines a substring of a concrete annotation. The respective linguistic annotation then applies to every element whose annotation (tag) contains this substring.
hasTagEndingWith G hasTagEndingWith hasTagEndingWith
Abstract As opposed to hasTag proper, the string representation defines the final subsequence of a concrete annotation. The respective linguistic annotation then applies to every element whose annotation (tag) ends with this substring.
hasTagMatching G hasTagMatching hasTagMatching
Abstract hasTagMatching is a subproperty of hasTag, so that results can be retrieved if the regular expression match is requested, but an exact value with reserved characters is defined
hasTagStartingWith G hasTagStartingWith hasTagStartingWith
Abstract As opposed to hasTag proper, the string representation specifies only the beginning of a concrete annotation. The respective linguistic annotation then applies to every element whose annotation (tag) startsWith this substring.
hasTier G hasTier hasTier
Abstract Assigns a linguistic annotation a string representation of the annotation layer ("tier", "level") where it is to be found, e.g., "pos" for Part of Speech annotation, "gloss" for linguistic glosses, etc.
