We want to store it with a lexical unit, as throughout the pipe lexical units split, merge, delete and get added, and we want that this information distributes over multiple output words, merges on the output words, etc.

This page will follow the development of word bound blanks in the apertium stream format.

Features[edit]

Transfer (Pull Request 1, Pull Request 2, Commit 1, Commit 2, Commit 3, Pull Request 3, Commit 4)[edit]

Chunker/Single-stage transfer[edit]

  • Wordbound blanks are a part of transfer word as a new side: blank.
  • Are ignored in pattern matching
  • Wordbound blanks are added just before the output LU from the LU that the lem/lemh is clipped from.
  • If the lem/lemh comes from a variable in the output then the balnk come from the LU which the lemma comes from, by tracing its variable assignment in <let>.
  • No regression. Stream without wordbound blanks work as-is.
  • Normal blanks don't move around while wordbound blanks move around.
  • When MLUs are formed the blanks are merged.
  • Tests added
  • If rule pattern has only one LU, the wordbound blank gets output with all output LUs of the rule
  • When using apertium-transfer -n, the wblanks print as they're supposed to.
  • Fix null flushing in transfer
  • Store blanks in queue and output wherever user has
    </b>
    in the rule output, so that users don't have to define a blank position anymore. (Blank reordering is done by wordbound blanks now)

Interchunk[edit]

  • No change needed as inter chunk doesn't access LUs inside the chunk.
  • Blank handling changed so the user doesn't have to worry about the blank position anymore.

Postchunk[edit]

  • Wordbound blanks are ignored in pattern matching
  • Wordbound blanks are added just before the output LU from the LU that the lem/lemh/whole is clipped from.
  • If the lem/lemh comes from a variable in the output then the blank comes from the LU which the lemma comes from, by tracing its variable assignment in .
  • No regression. Stream without wordbound blanks work as-is.
  • Normal blanks don't move around while wordbound blanks move around.
  • When MLUs are formed the blanks are merged.
  • Tests added
  • If rule pattern chunk has only one LU, the wordbound blank gets output with all output LUs of the rule
  • Blank handling changed so the user doesn't have to worry about the blank position anymore.

Recursive Transfer (Pull Request)[edit]

  • Wordbound blanks are read as part of LUs as a new side->wblank.
  • Wblanks reorder with the LUs in transfer based on where the lemma is clipped from.
  • Works even if lemma is clipped into a variable and the variable is later added in the output.
  • No regression. Stream without wordbound blanks work as-is.
  • Normal blanks don't move around while wordbound blanks move around.
  • When MLUs are formed the blanks are merged.
  • Tests added

Pretransfer (Pull Request)[edit]

  • Wordbound blanks distribute across parts when compounds are split into individual LUs

Separable (Pull Request)[edit]

  • Merge wordbound blanks and add to all LUs in rule output.
  • Works for both autoseq and revautoseq.

Analysis, Biltrans, Generation (Pull Request)[edit]

  • Parsing wordbound blanks as normal blanks for analysis, generation, biltrans.
  • Added a test for wordbound blank analysis.

HFST Analysis, Generation (Pull Request)[edit]

  • Parsing wordbound blanks as normal blanks for analysis and generation in hfst-proc.

Streamparser (Pull Request)[edit]

  • Wordbound blanks parsed as part of a lexical unit in the stream parser.
  • Can be accessed by class member: LexicalUnit.wordbound_blank.

Postgeneration (Pull Request, Commit 1, Commit 2)[edit]

  • Wordbound blanks merge when words merge.
  • Wordbound blanks apply to all output words when output of postgen rule are more than input words.
  • No regression for postgeneration without wordbound blanks.
  • Lots of tests added.

Tagger (Pull Request)[edit]

  • Parse wblanks as normal blanks

Rationale[edit]

Wordbound blanks will store information about a lexical unit that can help us with several applications where we want to send information through the pipeline but this information can't be sent as tags because it would break the FST matching in the modules.

We want to store it with a lexical unit, as throughout the pipe lexical units split, merge, delete and get added, and we want that this information distributes over multiple output words, merges on the output words, etc.

Formalism[edit]

Wordbound blanks will be denoted by double square brackets and will always appear right before a Lexical Unit.

[[wordboundblank]]^LU<tags>$

If there is no Lexical Unit in the stream (before the morph analyser and after the generator), then we have an end wblank as well.

[[wordboundblank]]word[[/]] word2 word3 [[wordboundblank]]word4[[/]]
