DKPro Core™ Type System Reference

The document provides detailed information about the DKPro Core type system.

The DKPro Core type system forms the interface between all the integrated components. Components store and retrieve their data from the UIMA CAS based on this type system. The type system design is using a rather flat hierarchy and a mostly loose coupling between annotations. It is offered as a set of modules, not as a single monolithic type system.

Coreference

Figure 1. Coreference types

This type system contains two types: CoreferenceChain and CoreferenceLink. The CoreferenceChain marks the beginning of a chain. It points to the first CoreferenceLink in the chain. Each CoreferenceLink then points to the next link.

CoreferenceChain

Metadata

Recording tagset and tag descriptions in the CAS is still a feature under development. It is not supported by all components and it is not yet well defined. Expect changes and enhancements to this feature in future versions of DKPro Core.

Figure 2. Metadata types

DocumentMetaData

URI: http://dkpro.github.io/dkpro-core/releases/1.8.0/docs/typesystem-reference.html#de.tudarmstadt.ukp.dkpro.core.api.metadata.type.DocumentMetaData
Name: de.tudarmstadt.ukp.dkpro.core.api.metadata.type.DocumentMetaData
Supertype: DocumentAnnotation
similar: http://vocab.lappsgrid.org/Document (LAPPS)

The DocumentMetaData annotation stores information about a single processed document. There can only be one of these annotations per CAS. The annotation is created by readers and contains information to uniquely identify the document from which a CAS was created. Writer components use this information when determining under which filename a CAS is stored.

There are two principle ways of identifying a document:

collection id / document id: this simple system identifies a document within a collection. The ID of the collection and the document are each simple strings without any further semantics such as e.g. a hierarchy. For this reason, this identification scheme is not well suited to preserve information about directory structures.
document base URI / document URI: this system identifies a document using a URI. The base URI is used to derive the relative path of the document with respect to the base location from where it has been read. E.g. if the base URI is file:/texts and the document URI is file:/texts/english/text1.txt, then the relativ path of the document is english/text1.txt. This information is used by writers to recreate the directory structure found under the base location in the target location.

It is possible and indeed common for a writer to initialize both systems of identification. If both systems are present, most writers default to using the URI-based systems. However, most writers also allow forcing the use of the ID-based systems.

In addition to the features given here, there is a language feature inherited from UIMA's DocumentAnnotation. DKPro Core components expect a two letter ISO 639-1 language code there.

Features of DocumentMetaData (6)

documentTitle (String): The human readable title of the document.
documentId (String): The id of the document.
documentUri (String): The URI of the document.
collectionId (String): The ID of the whole document collection.
documentBaseUri (String): Base URI of the document.
isLastSegment (Boolean): CAS de-multipliers need to know whether a CAS is the last multiplied segment. Thus CAS multipliers should set this field to true for the last CAS they produce.

Segmentation

Figure 5. Segmentation types

The segmentation type system consists of two primary areas: tokenization (including sentences), compound words, and document structure.

The Sentence annotation type is simply a span with no futher attributes.

The Token type may be explicitly linked to a part of speech, lemma, and stem. It is expected that if either of these annotations are present, the token explicitly refers to them. If more than one annotation of such a type, e.g. multiple part-of-speech annotations are present, then it is expected that the token links to the most probable one, while the others are only located at the same offsets.

Additionally, the Token can link into the syntactic constituency structure via the parent feature.

The document structure can be encoded using the Div types. The type Div itself is a generic type representing some element of the document structure more closely specified by the divType attribute. The value of divType corresponds to the tag used in some original document format or to the output of a text segmentation tool. E.g. when reading an HTML document, the divType for a paragraph would be p, whereas in a DocBook XML file, it would instead be para.

For typical structural elements, the subtypes Document, Heading, and Paragrah are available. Document is rarely used, since the basic assumption is that a CAS always represents a document.

Supertype: Annotation

similar: http://www.isocat.org/datcat/DC-1403 (ISOcat)

Token is one of the two types commonly produced by a segmenter (the other being Sentence). A Token usually represents a word, although it may be used to represent multiple tightly connected words (e.g. "New York") or parts of a word (e.g. the possessive "'s"). One may choose to split compound words into multiple tokens, e.g. ("CamelCase" -> "Camel", "Case"; "Zauberstab" -> "Zauber", "stab"). Most processing components operate on Tokens, usually within the limits of the surrounding Sentence. E.g. a part-of-speech tagger analyses each Token in a Sentence and assigns a part-of-speech to each Token.

Features of Token (6)

parent (Annotation): the parent of this token. This feature is meant to be used in when the token participates in a constituency parse and then refers to a constituent containing this token. The type of this feature is {@link Annotation} to avoid adding a dependency on the syntax API module.
lemma (Lemma): No description
stem (Stem): No description
pos (POS): No description
morph (MorphologicalFeatures): The morphological feature associated with this token.
id (String): If this unit had an ID in the source format from which it was imported, it may be stored here. IDs are typically not assiged by DKPro Core components. If an ID is present, it should be respected by writers.

SemanticArgument

Name: de.tudarmstadt.ukp.dkpro.core.api.semantics.type.SemanticArgument
Supertype: Annotation

The SemanticArgument annotation is attached to semantic arguments of semantic predicates. Semantic arguments are characterized by their semantic role, e.g. Agent, Experiencer, Topic. The semantic role of an argument is related to its semantic type (for communication verbs, the Agent can be a person or an organization, but typically not food). The semantic type of arguments is not yet covered by the SemanticType.

Features of SemanticArgument (1)

role (String): The role which the argument takes. The value depends on the theory being used, e.g. Arg0, Arg1, etc. or Buyer, Seller, etc.

Supertype: Annotation

The SemanticField is a coarse-grained semantic category that can be attached to nouns, verbs or adjectives. Semantic field information is present e.g. in WordNet as lexicographer file names. Previously, this kind of semantic information has also been called supersenses or semantic types.

Features of SemanticField (1)

Supertype: Annotation

One of the predicates of a sentence (often a main verb, but nouns and adjectives can also be predicates). The SemanticPredicate annotation can be attached to predicates in a sentences. Semantic predicates express events or situations and take semantic arguments expressing the participants in these events ore situations. All forms of main verbs can be annotated with a SemanticPredicate. However, there are also many nouns and adjectives that take arguments and can thus be annotated with a SemanticPredicate, e.g. event nouns, such as "suggestion" (with arguments what and by whom), or relational adjectives, such as "proud" (with arguments who and of what).

Features of SemanticPredicate (2)

category (String): A more detailed specification of the predicate type depending on the theory being used, e.g. a frame name.
arguments (FSArray of SemanticArgument): The predicate’s arguments.
