wordnet-as-a-service

This application exposes a few WordNet functions with a simple REST interface. In particular, can be used from a browser or as a text annotator.

The access to the WordNet database is done using extJWNL

How to use

Run the service by cloning it and use mvn compile && mvn exec:java or using Docker

docker run -p 5679:5679 jacopofar/wordnet-as-a-service

Retrieve hypernyms of a word:

curl http://localhost:5679/hypernym/1/fork

[
  {
    "POS": "noun",
    "word": "cutlery"
  },
  {
    "POS": "noun",
    "word": "eating utensil"
  },
  {
    "POS": "noun",
    "word": "division"
  },
  {
    "POS": "verb",
    "word": "lift"
  },
  ...

hyponyms

curl http://localhost:5679/hyponym/1/tool

[
  {
    "POS": "noun",
    "word": "abrader"
  },
  {
    "POS": "noun",
    "word": "abradant"
  },
  {
    "POS": "noun",
    "word": "bender"
  },
  ...

holonyms

 curl http://localhost:5679/holonym/1/France

 [
   {
     "POS": "noun",
     "word": "Europe"
   },
   {
     "POS": "noun",
     "word": "European Union"
   },
   {
     "POS": "noun",
     "word": "EU"
   },
   ...

synonyms, substance holonyms, meronyms and others

Just change the first of the URL with one of: holonym, entailment, substance_meronym, hyponym, antonym, synonym, substance_holonym, meronym, cause or hypernym.

The number in the URL is the senses to be considered when retrieving the word synsets. Increasing it will lead to more results but often seemingly "wrong" ones.

word definitions

Use

http://localhost:5679/definition/can

to get the glosses:

[
 {
   "POS": "noun",
   "gloss": "airtight sealed metal container for food or drink or paint etc.",
   "other terms": "[can, tin can, tin]"
 },
 {
   "POS": "noun",
   "gloss": "the quantity contained in a can",
   "other terms": "[can, canful]"
 },
 {
 ...

As an annotator

The server can also produce a list of annotations for a given text and pattern:

curl -X POST -H "Content-Type: application/json" '{"parameter":"pos=n,w=cat","text":"a feline is jumping right here"}' "http://localhost:5679/hypernyms_tagger/1"

will return:

{
  "annotations": [
    {
      "span_start": 2,
      "span_end": 8
    }
  ]
}

Generate a sample You can use the same format of the annotator to generate a sample of something matching the word type:

curl -X POST -H "Content-Type: application/json" -H "Cache-Control: no-cache" -H "Postman-Token: 41610ffd-f6e9-1573-850d-86b7bdcb29af" -d '{"parameter":"pos=n,w=bike"}' "http://localhost:5679/sample/hyponym/4"

will return, for example, velocipede.

This format is suitable to be used as an HTTP annotator/generator for Fleximatcher

Plurals

The server uses Evo inflector to educatedly guess English words plurals and match them (so, matching the hyponyms of "animal" will get "cats" as well as "cat")
