Is it possible to design an incremental RDF framework for such data ? The main ingredients would be a starting "header" RDF block containing feature declarations and metadata. Followed by 1 incremental RDF "data block" at a time. Which would essentially mean 1 row of the dataset at a time. An optional end block could also be included to specify the stream end. The "data blocks" could be very minimalist with just the uri indentifier and the relevant data. Its simply a matter of a special protocol (within the RDF domain) designed for the purpose of such large datasets. RDF although large in their overall representation of objects provides a lot of comprehension capabilities vs ARFF. Also theres the simple matter of having a single extra comma in your data crashing the whole algorithm ( in ARFF) ! Natively RDF is more in tune to "comprehend" data rather than represent data in an efficient form. Also have to keep in mind that occasionally the need arises for a human to comprehend such data (in the native machine form) and in such cases RDF is quite unsuitable. Another possibility could be to "compress" RDF using annotations. Of course that would mean designing and standardizing the annotations for all players who want to interact using the compressed form. Just my two cents .... Regds Surajit On 27 May 2011 21:20, chung <chvng at mail.ntua.gr> wrote: > Hi All, > Some criticism on RDF from the experience we've gained in OpenTox : > http://is.gd/qLJG3h .
