Random ideas

• User interface
  • editable feature instance comment (for a short time)
  • change Missing Features to list common feature types first (for Review, Description, Story Type, etc.)
  • item type overview page
    • a kind of personalized recent changes page per domain (for all Story instances, etc.)
    • rather than filtering by item type probably the search filter API should be used
  • model Skipforward users
    • create link to user resource when creating new items
      • item1 --descriptionCreatedBy--> user1
      • user1 --type--> SkipforwardUser --subclass--> Person
• linking to external web pages and LOD linking
• better DBTropes integration/feature type finder
  • full text search in DBTropes labels and comments
  • find feature types in intersection of features of two or more given items
  • immediate import of given feature types from DBTropes
• Refactoring
  • diff-based syncer
  • use TDB named graphs for SF namespaces?
• 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
• Similarity Manager tasks
  • handle nb features in Similarity Manager (use FT IDs instead of URIs or just ignore nb FTs)
  • invalidate similarity cache if FT hierarchy changed
  • make sure persistence is done properly
    • use faster persistence library, perhaps ​protobuf
• Item typing
  • item type represented by nb feature type instead of rdf:type?
  • infer item type by features used, with confidence
  • clustering - use clusters for annotation wizard, too
• Domain adaptation
• 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

• use Beans instead of JSON for ST models (fix String vs. HTML escaping ugliness in the process)
• 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)
• Book domain ontology
  • see also DBTropes
  • ​Literary technique, ​Fiction-writing modes, ​Style, ​Outline of fiction
• touch compatibility
• advanced search
  • also in comments etc., fields selectable, using Lucene
  • pattern search - i.e., show books written by X
  • search queries should be saveable, changeable, RSSable
  • there is much overlap with the Dojo UI recommendation channels here. Unify.
    • filter by feature(s)... (search)
    • rank by feature match(es)... (recommender)
      • sort by date
• allow editing/deleting items/features, at least for a short time
• conf/app dot usability (popup on one click?)
• item page: display reviews and descriptions separately
• more ajaxy ST UI
  • fetch all lists/tables using ajax - allows easy paging/reuse and should improve initial page load speed
• improve in feature recommender - generate feature instance overlap
  • that person seems to disagree wrt feature type X, please give more info
  • this feature type seems important to you but overlap with other people's annotations is low. Please annotate _that_ item.
  • I.e., apply similar techniques to the current annotation wizard on user level.
• speed up adding first item features
  • suggest typical feature types for the current item type
  • suggest feature types often used by you/in general
• better linking support in comments
  • more obvious links to create items
• item page streamlining
  • item summary: display aggregated "green" features, and most notable features in general (genre, etc.)
    • this summary (first words of description only, omit review) would also make a good tooltip for item labels
    • personalization for notable features (e.g., feature types you often use; any disagreements involving you; any replies to your statements)
  • filter negative features in view?
• 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
