Work Plan (from proposal)

Time Period	Goal	Details	Deliverable
Community Bonding Period May 6-26	Finalize formalism	Read up on GLR parsers Decide variable semantics and syntax See if there's a good way to handle interpolation (e.g. inserting clitics after first word of phrase)	Full description of planned formalism
Week 1 May 27-June 2	Begin parser	Get input Match and build trees based on literal tags and attribute categories	Minimal parser
Week 2 June 3-9	Add variables	Agreement Passing variables up the tree Setting variables for child nodes	Minimal parser with agreement
Week 3 June 10-16	Test with eng->spa	Noun phrases (this was started in the coding challenge) Basic verb phrases (some agreement, if time)	Simple eng->spa parser
Week 4 June 17-23	Continue parser	Weights Conditionals Multiple output nodes Anything else deemed necessary during Community Bonding or testing	Majority of initial specifications implemented
evaluation 1	Basic parser done		Parser-generator compliant with majority of initial specifications and rudimentary eng->spa instantiation
Week 5 June 24-30	Finish parser and continue eng->spa	Finish anything left over from week 4 Finish verb phrases	Fully implemented parser and working eng->spa for simple sentences
Week 6 July 1-7	Finish eng->spa and write reverser	Convert any remaining eng->spa rules Evaluate parser against chunking system Metrics: accuracy, speed of parser, compilation speed Write script to automatically reverse a ruleset All features currently described are at least in princible reversible	System comparison and rule-reverser
Week 7 July 8-14	Evaluation and testing	Evaluate the output of the reverser against current spa->eng system Write tests for all features Begin adding error messages	Test suite and report on the general effectiveness of direct rule-reversal
Week 8 July 15-21	Optimization and interface	Speed up the parser and compiler where possible Build interfaces for compiler, parser, and reverser Clean up code Re-evaluate speed	Command-line interfaces and updated system comparison
evaluation 2	Complete program		Optimized and polished parser-generator compliant with initial specifications, and complete end->spa transfer rules
Week 9 July 22-28	Do spa->eng	Identify differences between generated spa->eng and chunking spa->eng Fix generated spa->eng rules Report on effort required to correct reverser	Working spa->eng rules and report on the usefulness of rule-reverser
Week 10 July 29-August 4	Documentation	Convert initial specifications to full documentation Write tutorial Write recipe book containing at least minimal examples of everything listed at User_talk:Popcorndude/Recursive_Transfer#Linguistic.2Ftransfer_phenomena	Complete documentation of system
Weeks 11 and 12 August 5-18	Buffer zone	These weeks will be used for one of the following, depending on preceding weeks and discussions with mentors: Make up for delays in prior weeks Converting another language pair Experimenting with automated conversion of chunking rules Writing a ruleset composer for generating a preliminary ruleset from two other pairs (e.g. combine eng->spa and spa->cat to get approximate rules for eng->cat)	TBD
final evaluation	Project done		Complete, fully documented system with full ruleset for at least one language pair

Community Bonding

Todo list

• Determine exact semantics of lexical unit tag-matching
  • Are they ordered?
  • Are they consecutive?
• See if anyone has input on formalism syntax in general
• Mechanism for clitic-insertion
  • e.g. V2, Wackernagel
• Read about GLR parser algorithms
  • Find reading materials
  • Is there anything that can be done to make this finite-state? (probably not)
  • Should we just start with the naive implementation (what the Python script does) as a baseline?
• Conjoined lexical units - just treat as consecutive elements with no blank between?
• Syntax for mapping between sets of tags (e.g. <o3pl> -> <p3><pl>, <o3sg> -> <p3><sg>)
• Conditional output (e.g. modal verbs in English)
• Make sure all syntax is written down
• Begin writing tests
• Some way to match absence of a tag

May 25: LU tags are unordered (basically, every tag operation has the same semantics as <clip>, <equal><clip>..., or <let><clip>... in the chunker). Various other things have syntax but that syntax may not be properly documented yet.
