IL2 Exercise
The Subscribers
cannot switch again
to another provider
for the first 3 months,
but they can cancel
the switch
in 14 days
if they are not satisfied with services
like voice quality.
customers
are not allowed to change
companies again
within the first three months,
although they can cancel
the change
anytime within 14 days
if problems
such as poor call quality
are experienced.
Looked at the .fs file for the IL2 of these sentences proposed by Owen and Simon.
Issues:
- Scope of negation
- Is "can" a main verb or modifier of the main verb
- Do we need to retain the source language preposition?
- Detailed meanings of prepositions:
- Field workers have inventories of locative meanings: See recent article by Melissa Bowerman and someone else in a recent issue of Language.
- "But" Should it be a concession relation? RST?
- Coreference resolution: Replace "they" pointer to coreferent node (Owen), or make it an instance of an individual (Ed).
- We should follow some already estabilished methodology, even though there are still problems remaining.
- "If" should be a clausal connector like "but".
- Closely governed vs more variable pronouns
- What is the relation between "another" and "provider"? Do we have to name each mod arc?
Ed invents IL4. 11:13am. July 12, 2004.
Looked at Rebecca's IL2 for the same example:
- Includes more abstract concepts.
- Instances of times and relations between times.
- Framenet-style role names.
- Each node is labelled as an event or a state.
Looked at Advaith's IL2 for the same example:
Aligned IL1 Trees for these three versions:
- The Confederation of Indian Industries or the CII has also said that this year India's economy will witness a growth rate of 7.2 per cent.
- The CII stated that this year, India's economy would grow by 7.2%.
- Hindi original dependencies: said (CII) (will happen (growth) (this year) (Indian economy) (7.2%))
Issue: What is the end product?
1. One structure that represents what is common, with some branches where they differ.
Ed: What about structural ambiguities?
Nizar has dealt with these ambiguities in LCS.
2. Each IL1 has its own IL2. IL2's for corresponding sentences are at least partially similar.
Decision:
1. These two views are compatible.
2. There will be one IL2 with embedded disjunctions.
3. It will be possible to retrieve that parts of the IL2 that came from each IL1.
4. It will be possible to trace between IL2-IL1-IL0:
For any part of IL2, you can tell which part of which IL1 it came from and which part of which IL0 it came from .
Proposed Procedure:
1. User looks at graphical representation of three IL1s.
2. User aligns tree segments and indicates exact synonymy, inferential synonymy, and non-synonymy.
3. The system hypothesizes and IL2 with disjunctions for inferential and non-synonymy.
Japanese example:
We did a joint exercise to create an IL2 from two IL1s of a Japanese sentence:
- Sentence J2E1-9: This year, too, in addition to the birth of Mitsubishi Chemical, which has already been announced, other rather large-scale mergers may continue, and be recorded as a "year of mergers."
- Sentence J2E2-10: This year, which has already seen the announcement of the birth of Mitsubishi Chemical Corporation as well as the continuous numbers of big mergers, may too be recorded as the "year of the merger" for all we know.
(Nizar has the trees in TrEd)
Operations:
- Subordination changed to coordination
- Change part of speech of nominalization
- Undo relative clauses
- Remove light verbs
- Move a collective word lower in the NP
- Head switch
Both IL1s were transformed into an IL2 using these operations. There were still differences between the IL2s:
- Missing information -- in one IL1 and not in the other
- Slightly different ontology nodes
