Global Wordnet Formats

The Global WordNet Association provides three formats for which WordNets can be published and submitted to the ILI. These are as follows:

All of these formats are considered equivalent and a converter between them can be used at.

A converter and validator is available at http://server1.nlp.insight-centre.org/gwn-converter/

XML

The XML is specified by the following DTD. An example is given here:

The first three lines must always be as follows:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE LexicalResource SYSTEM "http://globalwordnet.github.io/schemas/WN-LMF-1.3.dtd">
<LexicalResource xmlns:dc="http://purl.org/dc/elements/1.1/">

A file may contain multiple WordNets in different languages:

The following information is required:

  • id: A short name for the resource
  • label: The full name for the resources
  • language: Please follow BCP-47, i.e., use a two-letter code if available else a three-letter code
  • email: Please give a contact email address
  • license: The license of your resource (please provide URL)
  • version: A string identifying this version (preferably follow major.minor format)
  • url: A URL for your project homepage
  • citation: The paper to cite for this resource
  • logo: A link to a Logo (Image URL) for this project

Extra properties may be included from Dublin core and in addition

  • status: The status of the resource, e.g., "valid", "checked", "unchecked"

  • confidenceScore: A numeric value between 0 and 1 giving the confidence in the correctness of the element.

      <Lexicon id="example-en"
           label="Example wordnet (English)"
           language="en"

           dc:publisher="Global Wordnet Association">

Each word (lexical entry) must have a unique id:

        <LexicalEntry id="w1">

The part of speech values are as follows:

  • n: Noun

  • v: Verb

  • a: Adjective

  • r: Adverb

  • s: Adjective Satellite

  • c: Conjunction

  • p: Adposition (Preposition, postposition, etc.)

  • x: Other (inc. particle, classifier, bound morphemes, determiners)

  • u: Unknown

              <Lemma writtenForm="grandfather" partOfSpeech="n"/>
          <Sense id="example-en-10161911-n-1" synset="example-en-10161911-n"/>
      </LexicalEntry>
      <LexicalEntry id="w2">
          <Lemma writtenForm="paternal grandfather" partOfSpeech="n"/>
          <Sense id="example-en-1-n-1" synset="example-en-1-n">

The set of relations between senses is limited to the following

  • antonym: An opposite and inherently incompatible word

  • also: See also, a reference of weak meaning

  • participle: An adjective that is a participle form a verb

  • pertainym: A relational adjective. Adjectives that are pertainyms are usually defined by such phrases as "of or pertaining to" and do not have antonyms. A pertainym can point to a noun or another pertainym

  • derivation: A word that is derived from some other word

  • domain_topic: Indicates the category of this word

  • domain_member_topic: Indicates a word involved in this category described by this word

  • domain_region: Indicates the region of this word

  • domain_member_region: Indicates a word involved in the region described by this word

  • exemplifies: Indicates the usage of this word

  • is_exemplified_by: Indicates a word involved in the usage described by this word

                  <SenseRelation relType="derivation" target="example-en-10161911-n-1"/>
          </Sense>
      </LexicalEntry>
      <LexicalEntry id="w3">
          <Lemma writtenForm="pay" partOfSpeech="v"/>

Syntactic behaviour is given as in Princeton WordNet

            <SyntacticBehaviour subcategorizationFrame="Somebody ----s" id="intransitive"/>
            <SyntacticBehaviour subcategorizationFrame="Somebody ----s somebody" id="transitive"/>
        </LexicalEntry>

Syntactic behaviour can also be given as part of the lexicon and referred to with the subcat property.

If a synset is already mapped to the ILI please give the ID here. All synsets must have an ID that starts with ID of the lexicon followed by a dash, e.g., example-en + - + local_synset_id.

        <Synset id="example-en-10161911-n" ili="i90287" partOfSpeech="n"
            members="example-en-10161911-n-1 example-en-1-n-1">
            <Definition>
                the father of your father or mother
            </Definition>

The members property gives the list of senses in order.

The set of relations between synsets is limited to the following:

If you wish to define a new concept call the concept "in" (ILI New). If there is no mapping to the ILI leave this field empty (it is required).

        <Synset id="example-en-1-n" ili="in" partOfSpeech="n">
            <Definition>A father's father; a paternal grandfather</Definition>

You can include metadata (such as source) at many points The ILI Definition must be at least 20 characters or five words

Pronunciation

Since 2021, the schema has the ability to represent the pronunciation of lemmas.

This is in the <Pronunciation> element, which gives the IPA text. It has the following attributes:

  • variety uses the IETF language tags to indicate dialect, for example encoding British English in IPA as en-GB-fonipa
  • notation: can encode further information such as indicating a particular dialect (this was notes in the paper)
  • phonemic: indicates whether the transcription is phonemic ('true') or phonetic (false), defaulting to 'false'
  • audio: gives the URL of an audio file of the pronuncation

An example of encoding is given below:

    <LexicalEntry id="ex-rabbit-n">
        <Lemma writtenForm="rabbit" partOfSpeech="n"/>
            <Pronunciation variety="en-GB-fonxsamp en-US-fonxsamp" 
	            audio ="https://path/rabbit.flac">'r\{bIt</Pronunciation>
        <Pronunciation variety="en-AU-fonxsamp" notation="weak vowel merger" 
	            audio ="https://path/rabbit1.flac">'r\{b@t</Pronunciation>
         </Lemma>
     </LexicalEntry>

Wordnet Extensions

A file may contain a lexicon extension which serves to augment an existing lexicon with new lexical entries, synsets, senses, relations, etc. They are defined much like regular lexicons, but the <Extends> element specifies the ID and version of the base lexicon:

    <LexiconExtension id="ewn-cs-example"
                      label="English WordNet Computer Science Terms (example)"
                      language="en"
                      email="goodmami@uw.edu"
                      license="https://creativecommons.org/publicdomain/zero/1.0/"
                      version="1.0">
        <Extends id="ewn" version="2020" />

The contents of the lexicon extension are the same as a regular lexicon with the addition of elements for external lexical entries, synsets, and senses. There are two uses of external elements. First, they allow one to add additional information to the corresponding element in the base lexicon, such as adding a new sense to an existing lexical entry:

        <ExternalLexicalEntry id="ewn-process-n">
            <Sense id="ewn-process-n-20000123" synset="ewn-20000123-n" />
        </ExternalLexicalEntry>

In the above example, the ewn-process-n ID is not used to create a new lexical entry, but rather it must already exist in the base lexicon. The external lexical entry (as well as other external senses or synsets) may only add information; therefore it may not specify metadata or elements required on lexical entries, such as for the lemma.

Second, they introduce an ID which may be referenced by new structures, such as the target of synset relation:

        <ExternalSynset id="ewn-06581154-n" />
        <Synset id="ewn-20000123-n" ili="" partOfSpeech="n">
            <Definition>a running instance of a computer program</Definition>
            <SynsetRelation relType="hypernym" target="ewn-06581154-n" />
        </Synset>

Due to the way external IDs are used, a lexicon extension may not exist in the same file as the base lexicon.

Wordnet Dependencies

Some wordnets depend upon others, such as those in the Open Multilingual Wordnet which depend upon the Princeton WordNet for synset structure. With the <Requires> element, it is possible to explicitly codify those dependencies:

    <Lexicon id="spawn"
             label="Multilingual Central Repository"
             language="es"
             email="bond@ieee.org"
             license="https://creativecommons.org/licenses/by/3.0/"
             version="1.3+omw"
             citation="Aitor Gonzalez-Agirre, Egoitz Laparra and German Rigau. 2012. `Multilingual Central Repository version 3.0: upgrading a very large lexical knowledge base &lt;http://adimen.si.ehu.es/web/sites/all/modules/pubdlcnt/pubdlcnt.php?file=http://adimen.si.ehu.es/~rigau/publications/gwc12-glr.pdf&amp;nid=18&gt;`_.

             url="http://adimen.si.ehu.es/web/MCR/"
             dc:publisher="Global Wordnet Association"
             dc:format="OMW-LMF"
             dc:description="Wordnet made from OMW 1.0 data"
             confidenceScore="1.0">
        <Requires id="pwn" version="3.0" />

This element signifies to an application processing the wordnet that the required wordnet should be loaded as well. The <Requires> element may also be used on a <LexiconExtension> for cases where the lexicon extends one wordnet but requires another.

JSON

The JSON format follows that of the XML and is based on JSON-LD An example of the JSON is as follows:

The top level of a JSON graph consists of an object with two properties @context which must be the fixed string referring to the JSON-LD context and @graph giving the lexicon format. This structure is required for submission to the Collaborative Interlingual Index, but web services may of course return shorter fragments of the structure.

{ 
  "@context": "http://globalwordnet.github.io/schemas/wn-json-context-1.3.json",
  "@graph": [{

The following are required properties of every WordNet (note the language must be given twice). @id gives the identifier of this wordnet (should be unique in this document) and @type must be lime:Lexicon.

      "@context": { "@language": "en" },
      "@id": "example-en",
      "@type": "lime:Lexicon", 
      "label": "Example wordnet (English)",
      "language": "en",
      "email": "john@mccr.ae",
      "rights": "https://creativecommons.org/publicdomain/zero/1.0/",
      "version": "1.0",

In addition the properties citation, url, logo, status, confidenceScore and any property from Dublin Core Elements 1.1 May be used

      "citation": "CILI: the Collaborative Interlingual Index. Francis Bond, Piek Vossen, John P. McCrae and Christiane Fellbaum, Proceedings of the Global WordNet Conference 2016, (2016).",
      "url": "http://globalwordnet.github.io/schemas",
      "publisher": "Global Wordnet Association",

The entries are given as a list under the entry property it requires an @id partOfSpeech and lemma and may have sense, synBehavior, status, confidence and Dublin Core properties. The lemma has only a single value writtenForm and the partOfSpeech must be one of the following: [ noun, verb, adjective, adverb, adjective_satellite, phrase, conjunction, adposition, other, unknown ]. The @id must be unique in the document, it is not the same as the @id of the wordnet or any other entry.

      "entry": [{
          "@id" : "w1",
          "lemma": { "writtenForm": "father" }, 
          "partOfSpeech": "noun",

The Sense requires only an @id and a synsetRef and may take status, confidenceScore, Dublin Core properties, an example.

          "sense": [{
              "@id": "example-en-10161911-n-1",
              "synsetRef": "example-en-10161911-n"
          }]
      }, {
          "@id" : "w2",
          "lemma": { "writtenForm": "paternal grandfather" }, 
          "partOfSpeech": "noun",
          "sense": [{
              "@id": "example-en-1-n-1",
              "synsetRef": "example-en-1-n",

A sense may also have any number of relations which have a relType from the list below and a target and may have Dublin Core properties

  • antonym: An opposite and inherently incompatible word

  • also: See also, a reference of weak meaning

  • participle: An adjective that is a participle form a verb

  • pertainym: A relational adjective. Adjectives that are pertainyms are usually defined by such phrases as "of or pertaining to" and do not have antonyms. A pertainym can point to a noun or another pertainym

  • derivation: A word that is derived from some other word

  • domain_topic: Indicates the category of this word

  • domain_member_topic: Indicates a word involved in this category described by this word

  • domain_region: Indicates the region of this word

  • domain_member_region: Indicates a word involved in the region described by this word

  • exemplifies: Indicates the usage of this word

  • is_exemplified_by: Indicates a word involved in the usage described by this word

                "relations": [{
                "relType": "derivation",
                "target": "example-en-10161911-n-1",
                "creator": "John McCrae"
            }]
        }]
    }, {
        "@id": "w3",
        "lemma": { "writtenForm": "pay" },
        "partOfSpeech": "verb",

The syntactic behavior is given here as follows:

          "synBehavior": [
             {"label": "Somebody ----s", "@id": "intransitive"}, 
             {"label": "Somebody ----s somebody", "@id": "transitive"}
           ]
      }],

Synsets are listed under the synset property. A synset requires only an @id. It may take an ili which is a code from the CILI (starting with ili:i), a definition, an iliDefinition (which must be given in English), status, confidenceScore, relations and Dublin Core properties.

In contrast to the XML form the ili is optional. If there is no match omit this tag, if you wish to propose a new synset add only a iliDefinition.

      "synset": [{
          "@id": "example-en-10161911-n",
          "partOfSpeech": "noun",
          "ili": "ili:i90287",

Definitions must have a gloss and may be have a language, in addition, status, confidenceScore and Dublin Core properties may be added. An iliDefinition is the same but may not have a language.

          "definition": [{
            "gloss": "that which is perceived or known or inferred to have its own distinct existence (living or nonliving)"
           }],

Synset relations are given as for sense relations except the target must be the @id of another synset not a sense. The following properties can be used:

  • hypernym: A concept with a broader meaning

  • hyponym: A concept with a narrower meaning

  • instance_hypernym: The class of objects to which this instance belongs

  • instance_hyponym: An individual instance of this class

RDF

We acknowledge the existence of two vocabularies to wordnet encoding. The wn-simple.ttl is based on the W3C RDF/OWL Representation of WordNet. This vocabulary is a straightforward encoding in RDF of the original Princeton data model where synsets, word senses, and words are the main classes. In the current version, new relations are added and additional axioms are provided to reinforce consistency.

The second RDF schema is significantly more flexible and builds principally on the W3C OntoLex Model. The details of the RDF serialization are principally built on those of the JSON-LD model. We include a separate tutorial here for the benefit of those who wish to create their resource natively in RDF.

The standard namespaces are

Each wordnet is an instance of the class lime:Lexicon and must have the following properties

  • rdfs:label: A name for the wordnet.
  • dc:language: The BCP 47 identifier for your language (usually a two letter code)
  • schema:email: An email address for the owner of the wordnet
  • dc:rights: A link to the license of the resource
  • owl:versionInfo: The version number of this resource

The mapping to the Lemon-OntoLex model is as follows:

  • Words are ontolex:LexicalEntry, they must have a ontolex:canonicalForm and a wn:partOfSpeech.
  • Senses are ontolex:LexicalSense, they must have a ontolex:reference
  • Synsets are ontolex:LexicalConcept.
  • Definitions and examples are given by skos:definition and skos:example optionally with a rdf:value.
