Random ideas

• User interface
  • item page streamlining (reviews first, list all feature instances instead of recent only)
  • welcome ST page for user (recent features by others for items also annotated by you - aggregate "agreeing" statements?)
    • "Annotations wanted for..." functionality
    • list interesting changes up to last login/some time ago
  • model Skipforward users
    • create link to user resource when creating new items
      • item1 --descriptionCreatedBy--> user1
      • user1 --type--> SkipforwardUser --subclass--> Person
  • ST annotation wizard
    • partially done but should additionally generate annotation overlaps between users
  • more ajaxy ST UI
    • in place update of filled-in annotation forms on Item pages
    • in place creation of annotation forms (by feature type substring search)
    • Ajax search
  • recommendation channel edit functionality
  • allow some simple HTML in comments (<i>,<a href=... skip=bool>)
  • filter negative features in view
  • touch compatibility
• Refactoring
  • diff-based syncer
  • use Beans instead of JSON for ST models (fix String vs. HTML escaping ugliness in the process)
  • use TDB named graphs for SF namespaces?
• Annotating items
  • similar-to/part-of/connected-to/successor-of feature types (further input for feature type recommender)
  • rules for deducing features (per-user basis, let user confirm generated feature instances)
  • sameAs links to other data sources
• Adaptation for music domain
  • simplify entering song/band information
  • download/cache songs
  • generate/play playlists, possibly with changing style over time (AutoDJ)
• Book domain ontology
  • see also DBTropes
  • ​Literary technique, ​Fiction-writing modes, ​Style, ​Outline of fiction
• Metadata sharing
  • optimize synchronization
  • cache and forward data on intermediate nodes in a secure fashion
  • superpeer nodes? Possibly represented within the network? (superpeer3-hasFeature-IsHubForMusic)
  • detect 'hot topics'
• Trust network - trust as in "peer is competent/peer's metadata is important")
  • ​Spreading Activation Models for Trust Propagation
  • explicit representation of trust (see Skippies ontology)
    • user interface changes for that
    • trust metric changes for that
• Ontology evolution
  • simple skipinions ontology editor
  • update and synchronize ontologies (and facts!) on peers

Implementation details

• 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
• Play sounds from JavaScript: ​http://www.schillmania.com/projects/soundmanager/
• show number of (existing) feature instances for each item (in ItemPane) - metadata certificates
• show number of feature instances for each feature class (in FeaturePane) and arithmetic mean/standard deviation for applicability - metadata certificates
• red/green blobs
• RDF importer that changes namespaces
• FloriansDiplomaThesis topics (Jul-Dec 2008)
  • related work: Semantic audio - ​List of publications
  • finish skiptrax ontology (see ​Music Ontology)
  • metadata importers/exporters (ID3, LastFM, etc.)
  • expert recommender (ask friends about people having knowledge about X/interests in Y)
  • scalable trust metric
  • fast computation of feature summaries
• User interface
  • Plain HTML pages for item/feature instances, just for browsing and linked data
    • For Person instances: Trust, feature(types) I (dis)agree with, last annotations, list of annotated items (by date/...)
    • For Item instances: Review stats, list of annotators (by degree of agreement), list of feature instances (by date/...)
    • For Feature types: Comment, example positive/negative item instances (by number of annotations), experts for this type, dispute list (for the current item), list of instances (for the current item)
