Introduction

Introduction

  • The subject of this chapter

    • The utilization of semantic knowledge in the process of understanding spoken inputs as practiced in the SRI speech understanding

Semantic Aspects of Translation


Introduction1

Introduction

  • Three functions in the understanding process

    • Filtering out phrase combinations

    • Building deep, internal structures

    • Making predictions

  • In this chapter, the major emphasis will be on the first two

PHASE I: Semantic Composition

“A power plant of a submarine was built by a company”

A power plant of a submarine was built by a company

“A power plant of a submarine was built by a company”

  • Grammar

    R1: S => NP VP

    R2: NP => NP PREPP

    R3: VP=> VP PREPP

    R4: PREPP => PREP NP

  • Lexicon

    NP: a-power-plant,

    a-submarine,

    a-company

    VP: was-built

    PREP: of, by

Phase i semantic composition3

PHASE I: Semantic Composition

  • Interacting with Discourse

    “General.Dynamics built the American submarine”

    “General.Dynamics built the Henry.L.Stimson”

    • The actual task of relating “the American submarine” to the Henry.L.Stimson is performed by the discourse component

    • Described fully in Chapter XI

PHASE I: Semantic Composition

  • Result of the quantification procedure (Phase II)

Phase i semantic composition5

PHASE I: Semantic Composition

  • Other Aspects of the SCRs

    • Multiple Node Lexical Entries

      • “beam of the Henry.L.Stimson”

      • “beam of 33 feet”

Phase i semantic composition6

PHASE I: Semantic Composition

  • Equiv Arcs

    • “The Henry.L.Stimson is a ship.”

Phase ii quantification

PHASE II: Quantification

  • “Did General.Dynamics build every Lafayette?”

  • The result of Phase I

    • “General.Dynamics built a Lafayette.”

Phase ii quantification1

PHASE II: Quantification

  • The Quantifiers

Semantic Aspects of Translation


Did general dynamics build every lafayette

“Did General.Dynamics build every Lafayette?”
