User:Khannatanmai/Secondary info apertium stream format

Original Proposal: Modifying the apertium stream format and eliminating dictionary trimming: User:Khannatanmai/GSoC2020Proposal_Trimming

Development of the original proposal: User:Khannatanmai/New_Apertium_stream_format

New Proposal: User:Khannatanmai/Alternate_stream_modification

This page will follow the development of the new proposal for adding secondary information in the Apertium stream format.

Formalism

Instead of putting secondary information inside Lexical Units, we will put all information inside word bound blanks, and the only information that will be put inside a Lexical Unit, will be global reading IDs. These IDs will identify readings in a window uniquely, so that information inside word bound blanks can refer to specific IDs if need be.

Example Output of biltrans:

What was earlier:

^de<pr><sf:del><id:11><W:1.6787>/of<pr><sf:del><id:11><W:5.0984>/from<pr><sf:del><id:11><W:0.0065>$

Will now be:

^de<pr><!11>/of<pr><!67>/from<pr><!68>$[{sf:del}{sl_ids:11; W:1.6787}{sl_ids:11; tl_ids:67; W:5.0984}{sl_ids:11; tl_ids:68; W:0.0065}]

Features

• A word bound blank will be defined by the syntax -> [{...}]
• It can have multiple blocks of information inside: -> [{...}{...}{...}]
• If a block of information doesn't have sl_ids or tl_ids, it refers to the entire LU (can be changed to {sl_ids:11; tl_ids:67,68} if we want that each block in a word bound blank should have IDs.
• sl_ids and tl_ids can take multiple ids (from source or from target). This helps deal with many-to-many relationships between the tokens of the two languages.

Thoughts

• compound id stores the id of the compound, but currently doesn't store the order of the parts in the compound (assumed to be ascending order of ids). mw_id however, has a blank block that preserves the order of the original parts that were made into an MWU.
• There seem to be several kind of blank blocks now. Either I let it be like that - disambiguate the kind of blank block based on its components. Or, blank blocks get names. Such as [{..}mw{..}cmp{..}]. This could work but doesn't seem like a great idea.

Possibilities:

^qʼaxal tzij ri Dyos<n><!24>$[{part_ids:20,21,22,23}{sl_ids:20; sf:qʼaxal}{sl_ids:21; sf:utzij}{sl_ids:22; sf:ri}{sl_ids:23; sf:Dyos}]

^qʼaxal tzij ri Dyos<n><!24>$[{sl_ids:20; sf:qʼaxal}{sl_ids:21; sf:utzij}{sl_ids:22; sf:ri}{sl_ids:23; sf:Dyos}]
