Transcribing and annotating spoken language with
EXMARaLDA
LREC-Workshop on XML-based richly annotated
corpora, Lisbon, 29 May 2004

  • Richly annotated corpora?
  • Richly annotable corpora?
  • Corpus creation
  • Exchangeability
  • Framework for things to be annotated?
  • ? Framework for annotations

Tier classification Types, Categories and speakers Tier names Tier names Stereotypes, Linguistic Types and Participants
Timeline Relative and/or absolute Absolute Absolute Relative and/or absolute
Overlap within tier No Yes No Yes (Bulldozer mode)
Link to media Optional (Audio only) Required (Video and Audio) Required (Audio only) Optional (Video and Audio)
Extensions Segmented Transcription TASX Level 2 None Symbolic subdivisions, symbolic associations

Beyond the single timeline
18
Beyond the single timeline
  • Simple annotation Part of speech tagging
  • each word a single entity
  • add suitable points to the timeline

19
Beyond the single timeline
Determine order of words (syllables, phonemes,
...) in overlaps or Allow bifurcations of the
timeline

Segmentation
  • EXMARaLDA Basic Transcription
  • Single timeline, multiple tiers
  • Intuitive transcription of verbal and non-verbal
    behaviour
  • Visualization
  • Exchange with TASX, PRAAT and ELAN
  • Simple (utterance level) annotation, e.g.
  • Utterance translation
  • Prosody (Dynamic Modulation etc.)

Finite State Machine (HIAT, GAT, DIDA, CHAT, ...)
  • EXMARaLDA Segmented Transcription
  • Bifurcated timeline, multiple tiers
  • Advanced (word, syllable, phoneme level)
    annotation, e.g.
  • POS-Tagging
  • Morphological transliteration
  • Intonation contour
  • Tone

speakers and whole interactions

Summary
  • EXMARaLDA Transcription Framework
  • Single timeline, multiple tiers data model
  • Common basis for different existing
    transcription system
  • Intuitive, efficient data model suitable for
  • User-friendly input
  • Flexible visualization
  • Simple flat annotations
  • Exchange with other tools
  • Extended data model Segmented transcription
  • Automatically generated from Basic
    transcription
  • More advanced flat annotations
  • Meta data annotation

23
Open questions 1
  • Limitations
  • Hierarchal annotation (e.g. Phrase structure)?
  • Discontinued constituents (e.g. German particle
    verbs)?
  • Cross level ( cross tier) annotation?
  • Visualization?

Open questions 2
  • Hierarchy Based Data Models
  • XML standardized storage
  • DTDs/Schemas validity check
  • XSLT transformation
  • XPath / XQuery query
  • DOM / NOM in-memory representation
  • Time based data models
  • XML standardized storage
  • How to check validity?
  • How to transform?
  • How to query?
  • AGLIB?

First step Understand differences and
commonalities between existing time- based data
models Second step Harmonize existing time
based models
