More Examples (Feb. 25)

  1. What do we want to extract from "If ..., then ..." constructions.
    The dependency parse in this example has "If Grandma had wheels" as an advcl modifier to the main clause.
    If Grandma had wheels, she would be a tea trolley.
    have.03 A0=Grandma; A1=wheels
    be.01 AM_ADV=had; A1=she; AM_MOD=would; A2=trolley
    (Grandma, had, wheels) mode:hypothetical
    (she, would be, a tea trolley) context: if (Grandma, had, wheels)
  2. How far to go in extending arg2 with post modifying clauses?
    The dependency graph has appositive link from sedative to drug and we have (Alcohol, is, a drug) -- do we infer the last two tuples?
    Alcohol is a drug, a sedative, which depresses the central nervous system
    be.01 A1=Alcohol; A2=drug
    depress.02 A0=sedative; UnknownRole(R-A0)=which; A1=system
    ? (Alcohol, is, a drug, a sedative, which depresses the central nervous system)
    (Alcohol, is, a drug)
    (a sedative, depresses, the central nervous system)
    ? (a drug, depresses, the central nervous system)
    ? (Alcohol, depresses, the central nervous system)
  3. Don't create Time: from every AM_TMP
    Clay holds water well , sometimes perhaps too well
    hold.01 A0=Clay; A1=water; AM_MNR=well; AM_TMP=sometimes
    (Clay, holds, water)
    x (Clay, holds, water) Time: sometimes too well
  4. Here is a new arg role AM-PRR. Treat it like any other arg2.
    The verb with ".LV" seems to be a "light verb" construction, with the noun frame mistake.01
    The frame for become.01 has A2 = "immune to various antibiotics" -- shift the adj to the relation.
    Most people make this mistake and over time can become immune to various antibiotics .
    make.LV A0=people; AM-PRR=mistake
    mistake.01 A0=people; C-V=make
    become.01 A1=people; AM-TMP=over; AM-MOD=can; A2=immune
    (Most people, make, this mistake)
    (Most people, can become immune, to various antibiotics) Time: over time


Examples of SRL to Extraction Rules

  1. Create a tuple for every A1 Verb A2 where A1 and A2 are any of {A0, A1, A2, …, A5}
    John was reading a book.
    A0: John read.01 A1: a book
    (John, was reading, a book)
    John sat in the library.
    A1: John sit.01 A2: in the library
    (John, sat, in the library)
  2. Ignore AM_MNR but use dependency graph to include adverbials in relation
    John was reading quietly.
    A0: John read.01 AM_MNR: quietly
    (John, was reading quietly, )
    John sat quietly in the library.
    A1: John sit.01 AM_MNR: quietly A2: in the library
    (John, sat quietly, in the library)
  3. Multiple arg2 with same arg1, second arg2 starts with a verb.
    Create two tuples, use both verbs in relation for arg2 that starts with verb.
    Don’t create the tuple with embedded verb.
    John hopes to read the book.
    A0: John hope.01 A1:to read the book
    A0: John read.01 A1: the book
     ? (John, hopes, to read the book)
    (John, hopes to read, the book)
    x (John, to read, the book)
    John sat in the library, reading a book.
    A1: John sit.01 A2: in the library AM_PRD: reading a book
    A0: John read.01 A1: a book
    (John, sat, in the library)
    (John, sat reading, a book)
    x(John, reading, a book)
    John reads books to stimulate his mind.
    A0: John read.01 A1: books AM_PRP: to stimulate his mind
    A0: John stimulate.01 A1: his mind
    (John, reads, books)
     ? (John, reads books, to stimulate his mind)
    (John, reads to stimulate, his mind)
    x (John, to stimulate, his mind)
  4. Multiple arg2 with same arg1, second arg2 starts with preposition.
    Append the arg that starts with a preposition to the previous arg2.
    John reads books for stimulating his mind.
    A0: John read.01 A1: books AM_PRP: for stimulating his mind
    A0: John stimulate.01 A1: mind
    (John, reads, books, for stimulating his mind)
     ? (John, reads books, for stimulating his mind)
    Tr (John, reads, books for stimulating his mind)
    Tr (John, reads, books)
    x (John, stimulating, his mind)
  5. Ignore args that start R-*
    John read a book that discussed philosophy.
    A0: John read.01 A1: a book that discussed philosophy
    A0: a book discuss.01 R-A0: that A1: philosophy
    (John, read, a book that discussed philosophy)
    (a book, discussed, philosophy)
    John read a book in which philosophy was discussed.
    A0: John read.01 A1: a book in which philosophy was discussed
    A0: a book discuss.01 R-AM-LOC: in which A1: philosophy
    (John, read, a book in which philosophy was discussed)
    (a book, discussed, philosophy)
  6. Designate the AM_TMP in tuples as Time:
    John read the book last Thursday.
    A0: John read.01 A1: the book AM_TMP: last Thursday
    (John, read, the book) Time: last Thursday
    Obama was elected in 2008.
    A0: Obama elect.01 A1: in 2008 AM_TMP: in 2008
    (Obama, was elected, in 2008) Time: in 2008
  7. Designate the AM_LOC in tuples as Location:
    John read the book in Paris.
    A0: John read.01 A1: the book AM_LOC: in Paris
    (John, read, the book) Location: in Paris
    Inslee was elected in Washington State.
    A0: Inslee elect.01 A1: in Washington State AM_LOC: in Washington State
    (Inslee, was elected, in 2008) Location: in Washington State
