Draft for Lexicographical data/Documentation page.

Template work in progress?

This is the main documentation page for lexicographical data on Wikidata. Since the new data system is not deployed yet, this documentation is incomplete and mostly based on the test system.

Data Model

visualization of the Lexeme data model

The data model of WikibaseLexeme describes the structure of the data that is handled as "Lexemes" in Wikibase. Here is a summary, for more detailed information, see mw:Extension:WikibaseLexeme/Data Model.

A Lexeme is a lexical element of a language, such as a word, a phrase, or a prefix (see Lexeme on Wikipedia). Lexemes are Entities in the sense of the Wikibase data model. A Lexeme is described using the following information:

• An ID. Lexemes have IDs starting with an "L" followed by a natural number in decimal notation, e.g. L3746552. These IDs are unique within the repository that manages the Lexeme. The ID can be combined with a repository's concept base URI to form a unique URI for the Lexeme.
• A Lemma for use as a human readable representation of the lexeme, e.g. "run".
• The Language to which the lexeme belongs. This is a reference to a concrete Item, e.g. Q1860 for English.
• The Lexical category to which the lexeme belongs. This is given as a reference to a concrete Item, e.g. Q34698 for adjective.
• A list of Statements to describe properties of the lexeme that are not specific to a Form or Sense (e.g. derived from or grammatical gender or syntactic function)
• A list of Forms, typically one for each relevant combination of grammatical features, such as 2nd person / singular / past tense. A Form is described using the following information:
  • An ID. Forms have IDs starting with the ID of the Lexeme they belong to, followed by a hyphen ("-") and an "F", followed by a natural number in decimal notation: e.g. L3746552-F7
  • A representation, spelling out the Form as a string.
  • A list of grammatical features that define for which syntactic role the given form applies. These are given as references to a concrete Items, e.g. Q814722 for participle.
  • A list of Statements further describing the Form or its relations to other Forms or Items (e.g. pronunciation audio, rhymes with, used until, used in region)
• A list of Senses, describing the different meanings of the lexeme (e.g. "financial institution" and "edge of a body of water" for the English noun bank). A sense is described using the following information:
  • An ID. Senses have IDs starting with the ID of the Lexeme they belong to, followed by a hyphen ("-") and an "S", followed by a natural number in decimal notation: e.g. L3746552-S4. These IDs are unique within the repository that manages the Lexeme. The ID can be combined with a repository's concept base URI to form a unique URI for the Sense.
  • A Gloss, defining the meaning of the Sense using natural language.
  • A list of Statements further describing the Sense and its relations to Senses and Items (e.g. translation, synonym, antonym, connotation, register, denotes, evokes).
