14.1 Defining Local Discourse Context and Discourse Entities

• Think of local context as including
  • the syntactic and semantic analysis of the preceding sentence
  • a list of objects mentioned in the sentence that could be antecedents for later pronouns and definite noun phrases.

  1a	Jack[i] lost his wallet[j] in his car[k].
  1b	He[i] looked for it[j] for several hours.
  1c	Later he[i] found the wallet[j] under the front seat[k??].

• Jack in 1a is said to be the antecedent for he in 1b.
  That is, the pronoun and antecedent co-refer.
