A||GO – web services platform

The advances of Linkmedia in terms of multimedia analysis and indexing lead to the elaboration of multiple tools available as web-services through the A||GO platform. This platform, created in the context of the PlaSciDo Project and co-managed by Linkmedia and SED Inria, is based on a system of Docker containers allowing multiple environments for a stable access to the web-services. Its philosophy is simple:

  1. Choose your algorithm
  2. Upload your data
  3. Retrieve the result

The multimedia services currently available on A||GO are, w.r.t their modality:

  • Audio processing
    • SaMuSa: music/speech segmentation
    • SilAD: silence detection
    • repeated audio motif discovery
    • LORIA STS v1 and v2: two speech transcription systems from LORIA Multispeech
    • SpeaDS: Speaker Diarization System (who speaks when in an audio stream)
  • Text processing
    • NERO: name entity recognition
    • TermEx: keywords/indexing terms detection
    • Otis!: topic segmentation
    • Hi-tost: hierarchical topic structuring
  • Video processing
    • Vidseg: detection of cuts between visual shots
    • HUFA: face detection

The results of these services can be agglomerated and combined through a common json file. Details about technology transfer and licenses are available within the service documentations on A||GO. For more information, please contact us.
