ChaToEaf

Converts CLAN CHAT transcripts to ELAN .eaf files

ELAN doesn't support meta-data like @Date, @Location, etc. so almost all CHAT header meta-data is lost when converting to .eaf.

This conversion will only work well for CHAT transcripts that are fully aligned; i.e. all lines include time alignment bullets.

The CLAN parser is not exhaustive; it one parses:

  • Disfluency marking with &+ - e.g. so &+sund Sunday
  • Non-standard form expansion - e.g. gonna [: going to]
  • Incomplete word completion - e.g. dinner doin(g) all
  • Acronym/proper name joining with _ - e.g. no T_V in my room
  • Retracing - e.g. <some friends and I> [//] uh or and sit [//] sets him
  • Repetition/stuttered false starts - e.g. the <picnic> [/] picnic or the Saturday [/] in the morning
  • Errors - e.g. they've <work up a hunger> [* s:r] or they got [* m] to

Serializing to “ELAN EAF Transcript” text/x-eaf+xml

Command-line configuration parameters for serialization:
--commentLayer=Layer Commentary
--noiseLayer=Layer Noise annotations
--lexicalLayer=Layer Lexical tags
--pronounceLayer=Layer Manual pronunciation tags
--authorLayer=Layer Name of transcriber
--dateLayer=Layer Document date
--languageLayer=Layer The language of the whole transcript

--useConventions=Boolean Whether to use text conventions for comment, noise, lexical, and pronounce annotations
--ignoreBlankAnnotations=Boolean Whether to skip annotations with no label, or process them
--minimumTurnPauseLength=Double Minimum amount of time between two turns by the same speaker, with no intervening speaker, for which the inter-turn pause counts as a turn change boundary. If the pause is shorter than this, the turns are merged into one.
