DBTropes.org data frontend: Skipforward

Hi all!

Short version:
DBTropes/TVTropes movie/game/book... content information is now 
available in Skipforward which can be used as a richer browser for the 
data set as well as a recommender engine in that context.
http://tinyurl.com/cns3ocy (movie "Braveheart", its tropes, and similar 
items)
http://dbt.skipforward.net/skipforward (main demo entry point)
(frontend may be slow, it's a rather underpowered machine etc)


Long version:

DBTropes.org is a Linked Data wrapper to TVTropes.org, a wiki 
associating features ("Tropes") to works of fiction. Want to know what 
movies to watch if you crave shiny technology? DBTropes/TV Tropes can 
tell you [1].
http://dbtropes.org/

Skipforward is a distributed recommendation system using a lightweight 
ontology approach for formalizing opinions about item features. Items 
can be things such as songs or board games; example item features are 
the genre of a song or the degree of chance in a board game.

For demonstration purposes, we imported the whole DBTropes data set into 
a demo instance of Skipforward. The demo offers a simple HTML interface 
to browse, view, and search items. Tropes are shown as item features 
and, wherever possible, similar items are suggested with respect to 
their matching features. The whole recommendation procedure is done live 
(there is no pre-calculated similarity between the items).

The demo is located at
http://dbt.skipforward.net/skipforward

Here is a good recommendation example:

The demo might respond slowly or time out occasionally as it's running 
on a small machine with code that hasn't been fully optimized. Please 
don't flood the machine with requests.

It should be mentioned that recommendations are somewhat 
non-deterministic and not optimal as the algorithms are not optimized 
for this sort of input data and little optimization has gone into the 
recommendation process wrt DBTropes data/schema. The main points of 
Skipforward are its multi-user capabilities which are not really visible 
in the DBT demo. Go to http://skipforward.net/ if you are interested in 
a multi-user (and, with an own account, read/write) Skipforward demo.

Just to mention a few numbers, there are around 33000 items with more 
than 2 million features in the DBT/Skipforward demo.

Many thanks to Markus Fuchs who implemented most of the tweaks needed 
for the DBT demo.

Best,
Malte
