Short Description

ANNIS is a browser-based search and visualization platform for complex, multi-layered linguistic corpora. It enables querying and displaying annotated texts, audio, and video materials across multiple linguistic levels. The target audience consists of researchers and educators in corpus linguistics working with structured linguistic data. Universities benefit from the free, platform-independent use to support research and teaching in linguistics and computational linguistics.

Goals

  • Annotate, migrate, and analyze linguistic data
  • Provision of a browser-based search and visualization architecture for complex multi-layered corpora
  • Support in converting between various file formats for linguistic data
  • Promotion of collaboration with third parties through compatible tools and open standards
  • Development and maintenance of open-source software in the field of corpus linguistics and morphology

Work Packages

  • WP1: Development and maintenance of ANNIS (Annotation, search, and visualization of complex multi-layered corpora)
  • WP2: Development and maintenance of Annatto (Format conversion based on the graphANNIS data model)
  • WP3: Development and maintenance of Artemisia (Annotation editor, in development)
  • WP4: Development and maintenance of graphANNIS (Integration of corpus search into own software)
  • WP5: Maintenance and provision of demo corpora and documentation
  • WP6: Community and open-source contribution (bug reporting, discussion, code contributions via GitHub)
  • WP7: Support and integration of third-party tools

Methods

  • Open Source Apache 2.0 license
  • Cross-Platform (Linux, Mac, Windows) development
  • Browser-based search and visualization architecture
  • Use of Java OpenJDK 11 as runtime environment
  • Use of the graphANNIS data model as intermediate representation
  • Workflow-based configuration (for Annatto)
  • Command-line application (Annatto)
  • Support for multiple annotation levels (syntax, semantics, morphology, prosody, referentiality, lexicon, etc.)
  • Multi-layered linguistic corpora with complex annotations
  • Support for audio/video annotations (for spoken language)
  • Integration of multimodal data (e.g. EXMARaLDA, time-aligned audio)
  • Use of AQL (ANNIS Query Language) for queries
  • Support for multiple tokenizations and subtoken-based segmentations
  • Creation of user-defined HTML visualizations with CSS
  • Migration between file formats (e.g. PAULA, TreeTagger, EXMARaLDA, CoNLL-U, XLSX, TextGrid, PTP)
  • Conducting consistency checks during conversion (Annatto)
  • Use of GitHub for development, issue tracking, and discussions
  • Documentation via online guides, developer guides, and tutorials
  • Provision of demo corpora in relANNIS and PAULA format
  • Support for parallel corpora and alignment information
  • Integration into external software via graph
