Grouping WordNet Senses

How can you tell the senses apart?

In which cases should senses be merged?

In which cases should they be kept separate?

wn senses for the verb live

WN senses for the verb ‘live’

1. dwell, shack, reside, live, inhabit, people, populate, domicile, domiciliate -- (make one's home or live in; "I live in a 200-year old house”)2. live -- (lead a certain kind of life; live in a certain style; "we had to live frugally after the war")3. survive, last, live, live on, go, endure, hold up, hold out -- ("The racecar driver lived through several very serious accidents")4. exist, survive, live, subsist -- (support oneself, "Can you live on $2000 a month in New York City?)

grouped senses for live

Grouped senses for ‘live’

GROUP 1: WN2, WN7 (live a certain style, pursue a positive existence)

GROUP 2: WN3, WN4, WN5 (survive, support oneself, have life)

Can you live on $2000 a month in New York City? ?agentive

The racecar driver lived through several very serious accidents

My grandfather lived until the end of war

SINGLETON: WN1 (reside)

"I live in a 200-year old house” non-agentive with a locative PP

SINGLETON: WN6 (experience)

“I lived through two divorces'‘ non-agentive transitive

SINGLETON: WN4 (be a student)

“She is reading for the bar exam” agentive, atelic

SINGLETON: WN5 (teach) causative, agentive

which criteria should be used for distinguishing grouped senses

Which criteria should be used for distinguishing grouped senses?

MERGE AS ONE GROUP:

differences in syntactic alternations

differences in syntactic type of arguments

differences in selectional restrictions (except for agentivity)

DO NOT MERGE:

- differences in entailments

differences in the type of events (e.g. physical vs. abstract)

differences with respect to agentivity

causative alternation

Causative Alternation

Causative/inchoative senses are grouped as one sense.

(1) John opened the door

(2) The door opened

(3) The wind opened the door

Group 1: cause to become open

Alternating sentences are usually related to each other by means of entailment, for example, the sentences in (1) and (3) entail the sentence in (2).

detransitivization

Detransitivization

Transitive and detransitivized uses of the verbs are merged as one sense

(1) John is eating an apple

(2) John is eating

Note that the sentence in (1) entails the sentence in (2)

verbs of motion

Verbs of Motion

Verbs of manner of motion and verbs of directed motion are merged as one sense

(1) John ran (for an hour)

(2) John ran into the store

In this example, the sentence in (2) entails the sentence in (1).

syntactic type of arguments
Syntactic Type of Arguments

If senses differ only with respect to the

syntactic type of arguments, they should be merged

  • He told me about the promotion
  • He told me that you had been promoted
semantic classes of arguments
Semantic Classes of Arguments
  • If senses differ only in the semantic class of one of the arguments, they should be merged

6. play, spiel -- (replay (as a melody); "Play it again, Sam"; "She played the third movement very beautifully")

7. play -- (perform music on (a musical instrument); "He plays the flute"; "Can you play on this old recorder?")

semantic classes of arguments agentivity
Semantic Classes of Arguments: Agentivity
  • Do not merge senses which differ in agentivity

Serve:

Group 1: function (His freedom served him well)

Group 2: work (He served in Congress)

differences in entailments
Differences in Entailments

Do not merge senses with different entailments:

Appear:

Group 1: come into existence

Homo sapiens appeared millions of years ago

Group 2: come into sight, view

He suddenly appeared at the wedding

semantic type of events

Semantic Type of Events

Do not merge senses which are distinguished by the type of an event, such as physical perception vs. an abstract or mental perception. Concrete/abstract distinction

Group 1: Perceive by sight (Can you see the bird?)

Group 2: Witness, learn (I see that you have been promoted)
