Thesis topics

  • Adaptation for music domain
    • metadata importers/exporters
    • adapter for own audio collection
    • simplify entering song/band information
    • download songs
    • generate playlists, possibly with changing style over time (AutoDJ)
  • Metadata sharing
    • optimize synchronization
    • cache and forward data on intermediate nodes in a secure fashion
  • Trust network
  • User interface
    • show number of (existing) feature instances for each item (in ItemPane)
    • show number of feature instances for each feature class (in FeaturePane) and arithmetic mean/standard deviation for applicability
    • red/green blobs
    • small evaluation
    • proper search/view/enter
  • Ontology evolution
    • simple skipinions ontology editor
    • update and synchronize ontologies (and facts!) on peers

Other things

  • Create an RDF importer that changes namespaces
  • Facts/graph synchronization idea
    • every peer implements
      • String getDiffForNamespace(String namespace, String haveHash, String wantHash)
      • String getMostCurrentHash()
      • String isValid(String hash)
      • String getPubkey()
      • ? subscribe(?)
    • logic: once a day, every machine dumps its 'own' facts to an NTriples file along with a timestamp and the data's hash
    • when peers call getDiffForNamespace(), a diff from haveHash.dat to wantHash.dat is calculated and sent
    • Distributed Storage
      • simple distributed storage (without signatures) with trust can be implemented usind getMostCurrentHash and isValid
      • distributed storage with signatures can be implemented with getPubkey (using a true keyserver might be desirable though)
      • optimized push synchronization could use some subscription mechanism. Integrate with XMPP pubsub?
    • Ontology evolution/rules
      • rules that upgrade existing facts could be added to the diff file

Done

  • Internal namespaces for ontologies (xmpp://schwarz@xmpp.km.opendfki.de/ont/ludopinions#UsesDice)
    • this way people can create own ontologies, and ontology management/evolution can be done similar to facts synchronization
