The Observatory Integrated Ontology

Abstract

The OBservatory Integrated Ontology (OBIO) ontology is designed to integrate tweet metadata with various types of linguistic knowledge and Linked Open Data (LOD), such as named entities, dependencies, and frame semantics.

Cross-reference for The Observatory Integrated Ontology classes, object properties and data properties back to ToC

This section provides details for each class and property defined by The Observatory Integrated Ontology.

Concept^c back to ToC or Class ToC

IRI: http://rdfs.org/sioc/ns#Post

A Post is an article or message posted by a User to a Forum. A series of Posts may be threaded if they share a common subject and are connected by reply or by date relationships. Posts will have content and may also have attached files, which can be edited or deleted by the Moderator of the Forum that contains the Post. (from sioc)

is in domain of: created ^dp, has_container ^op, mentions ^op, nb_like ^op, nb_repost ^op, post_metrics ^op, sentence ^op

Container^c back to ToC or Class ToC

IRI: http://rdfs.org/sioc/ns#Container

Container is a high-level concept used to group content Items together. The relationships between a Container and the Items that belong to it are described using sioc:container_of and sioc:has_container properties. A hierarchy of Containers can be defined in terms of parents and children using sioc:has_parent and sioc:parent_of. (from nif)

has sub-classes: Forum ^c

Entity^c back to ToC or Class ToC

IRI: https://w3id.org/okg/obio-ontology/Entity

<to-add>

is in domain of: anchorOf ^op, hasMatchedURL ^op
is disjoint with: Phrase ^c

Forum^c back to ToC or Class ToC

IRI: http://rdfs.org/sioc/ns#Forum

Forums can be thought of as channels or discussion area on which Posts are made. A Forum can be linked to the Site that hosts it. Forums will usually discuss a certain topic or set of related topics, or they may contain discussions entirely devoted to a certain community group or organisation. A Forum will have a moderator who can veto or edit posts before or after they appear in the Forum. Forums may have a set of subscribed Users who are notified when new Posts are made. The hierarchy of Forums can be defined in terms of parents and children, allowing the creation of structures conforming to topic categories as defined by the Site administrator. Examples of Forums include mailing lists, message boards, Usenet newsgroups and weblogs. (from sioc)

has super-classes: Container ^c
is in range of: has_container ^op

Online Account^c back to ToC or Class ToC

IRI: http://xmlns.com/foaf/0.1/OnlineAccount

foaf:OnlineAccount represents the provision of some form of online service, by some party (indicated indirectly via a foaf:accountServiceHomepage) to some foaf:Agent. The foaf:holdsAccount property of the agent is used to indicate accounts that are associated with the agent. (from foaf)

has sub-classes: User ^c

Phrase^c back to ToC or Class ToC

IRI: http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core#Phrase

A nif:Phrase can be a nif:String, that is a chunk of several words or a word itself (e.g. a NounPhrase as a Named Entity). The term is underspecified and can be compatible with many defintitions of phrase. Please subClass it to specify the meaning (e.g. for Chunking or Phrase Structure Grammar). Example: ((My dog)(also)(likes)(eating (sausage))) (from nif)

has super-classes: String ^c
is in range of: anchorOf ^op, mentions ^op
is disjoint with: Entity ^c

Reply^c back to ToC or Class ToC

IRI: https://w3id.org/okg/obio-ontology/Reply

A Reply is a Post that directly answers a previous Post, by adding additional content.

has super-classes: Concept ^c
is in domain of: reply of ^op

RePost^c back to ToC or Class ToC

IRI: https://w3id.org/okg/obio-ontology/RePost

A RePost if a Post that is republished by another user, without modifications.

has super-classes: Concept ^c

is in range of: sentence ^op

String^c back to ToC or Class ToC

IRI: http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core#String

Individuals of this class are a string, i.e. Unicode characters, who have been given a URI and are used in the subject of an RDF statement. This class is abstract and should not be serialized. (from nif)

has sub-classes: Phrase ^c, Word ^c

is in range of: inter ^op, superString ^op

User^c back to ToC or Class ToC

IRI: http://rdfs.org/sioc/ns#User

A User is an online account of a member of an online community. It is connected to Items and Posts that a User creates or edits, to Containers and Forums that it is subscribed to or moderates and to Sites that it administers. Users can be grouped for purposes of allowing access to certain Forums or enhanced community site features (weblogs, webmail, etc.). A foaf:Person will normally hold a registered User account on a Site (through the property foaf:holdsAccount), and will use this account to create content and interact with the community. sioc:User describes properties of an online account, and is used in combination with a foaf:Person (using the property sioc:account_of) which describes information about the individual itself. (from sioc)

Word^c back to ToC or Class ToC

IRI: http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core#Word

The Word class represents strings that are tokens or words. A string is a Word, if it is a word. We don't nitpic about whether it is a a pronoun, a name, a punctuation mark or an apostrophe or whether it is separated by white space from another Word or something else. The string 'He enters the room.' for example has 5 words. Words are assigned by a tokenizer NIF Implementation. Single word phrases might be tagged as nif:Word and nif:Phrase. (from nif)
