What does language do?

“Harry walked to the cafe.” “Harry walked into the cafe.”

A sentence can evoke an imagined scene and resulting inferences:

CAFE CAFE

– Goal of action = at cafe– Source = away from cafe– cafe = point-like location

– Goal of action = inside cafe– Source = outside cafe– cafe = containing location

Form Meaning

A construction is a form-meaning pair whose properties may not be strictly predictable from other constructions.

Linguistic knowledge consists of form-meaning mappings:

Constructions as maps between relations

“is” + Action + “ing”before(“is”, Action)suffix(Action, “ing”)

Mover + Motionbefore(Mover, Motion)

Complex constructions are mappings between relations in form and relations in meaning.

Embodied Construction Grammar

• Embodied representations– active perceptual and motor schemas– situational and discourse context

• Construction Grammar– Linguistic units relate form and meaning/function.– Both constituency and (lexical) dependencies allowed.

• Constraint-based (Unification)– based on feature structures (as in HPSG)– Diverse factors can flexibly interact.

Inference and Conceptual Schemas

• Hypothesis: – Linguistic input is converted into a mental simulation based on bodily-

grounded structures.

• Components:– Semantic schemas

• image schemas and executing schemas are abstractions over neurally grounded perceptual and motor representations

– Linguistic units • lexical and phrasal construction representations invoke schemas, in part

through metaphor

• Inference links these structures and provides parameters for a simulation engine

Summary: ECG

• Linguistic constructions are tied to a model of simulated action and perception

• Embedded in a theory of language processing– Constrains theory to be usable– Frees structures to be just structures, used in processing

• Precise, computationally usable formalism– Practical computational applications, like MT and NLU– Testing of functionality, e.g. language learning

• A shared theory and formalism for different cognitive mechanisms– Constructions, metaphor, mental spaces, etc.

Embodied Compositional Semantics

after

Ellen Dodgeedodge@berkeley.edu

Questions

• What is the nature of compositionality in the Neural Theory of Language?

• How can it be best represented using Embodied Construction Grammar?

Examples

• He bit the apple• He was bitten (by a toddler) • He bit into the apple • His white teeth bit into the apple.• He shattered the window• The window was shattered• The window shattered

Compositionality

• Put the parts together to create the meaning of the whole.

• Questions:– what is the nature of the parts?– How and why do they combine with one another?– What meaning is associated with this composition?

Short answers

• Parts = constructions, schemas• Combination = binding, unification • Meaning of the whole = simulation of

unified parts

Simulation parameters

• Constructions unify to create semantic specification that supports a simulation

• Two types of simulation parameters for event descriptions:– Event content– Event construal

Summary

• Parts = constructions, schemas• Combination = binding, unification • Meaning of the whole = simulation of the

combined parts

First example

• He bit the apple.

Key points

• In prototypical verb-argument structure construction combinations, verb meaning is very similar to argument structure meaning.

• Verbs whose meaning partially overlaps that of a given argument structure constructions may also co-occur with that argument structure construction

• These less prototypical combinations may motivate extensions to the central argument structure constructions
