kennyluck, is this the right proof?

It gives me the following error:

Error: uncaught exception: Can't convert from NT"9980000000"^^<http://dbpedia.org/units/Dollar>

00:20:06 [oshani]

also Tabulator's n3 parser seem to choke on http://people.csail.mit.edu/kennyluck/SVN-DIG/Papers/SocialComp/code/cwm_test/intermidiate_result.n3

hey ericP did you get my notes about building swobject?

presbrey, yeah, i hadn't really thought about the functionality if the web client code isn't there

03:12:25 [ericP]

been hacking a bit to make it handle file:// relatively nicely, and mostly to make it construct RdfDBs regardless of whether you have xml parsers, web clients, etc.

03:13:25 [ericP]

the only web client interface is boost::asio, and if i weren't so yorked at dlib for changing ifaces over minor releases, i'd try to figure out how to use it to do GET

03:14:41 [ericP]

do you want to grab a newer boost? i think asio shows up in 1.35 (current version is maybe 1.38)

I am looking at a foaf generated by identi.ca with Tabulator, and I am finding that it does not expose the information about the person (name, location, etc) but I can see it if I look at the raw source. Does anyone know what I might be doing wrong?

17:08:48 [timbl]

timbl (n=timbl@w3cdhcp5.w3.org) has joined #dig

17:32:44 [timbl]

Oshani, to see a lot of time used scanning for RDFa, try loading the HTML5 spec http://dev.w3.org/html5/spec/Overview.html

17:33:48 [oshani]

timbl, yes.. that's very interesting

17:34:45 [oshani]

I wonder if there's any way I could speed up the parsing for large docs like that

17:35:02 [timbl]

Is the algorith, currently linear in the size of the document?

17:35:19 [oshani]

yes, linear

17:39:25 [oshani]

timbl, BTW I am currently experimenting on a new pane on Tabulator to send twitter updates using pushback - so far so good :-)

17:39:44 [oshani]

the only negative thing about this would be that I am relying on the DERI's pushback controller hosted on their server - so, it's centralized

17:45:01 [fturkmen]

oshani, just a suggestion for better parsing; you may try different xml parsers (hopefully there is an implementation required by your application, JS I guess), apart from SAX implementations, you may want to try this : http://vtd-xml.sourceforge.net/, and some possible inspirations from AJAX approaches

17:47:17 [oshani]

fturkmen, thanks... but I wonder whether these can be used for efficient HTML DOM traversal.

17:47:35 [oshani]

jQuery is the best out there that I know of

17:47:57 [lkagal]

lkagal has quit ()

17:49:26 [fturkmen]

oshani, you need to parse the document or traverse a DOM tree?

17:50:15 [oshani]

you have to parse the document by traversing the DOM tree isn't it? correct me if I'm wrong

17:56:18 [lkagal]

lkagal (n=lkagal@30-6-179.wireless.csail.mit.edu) has joined #dig

18:11:36 [timbl]

twitter updates using pushback -- sending the update using the Twitter API or using a server to translate from SPARQL to Twitter API?

18:12:00 [timbl]

centralised, but so is wtwitter

18:12:11 [timbl]

they just havce a twitterwrapper

18:12:15 [timbl]

That is oK IMHO

18:13:13 [timbl]

oashani, re parsiung, you start from the DOM, not the but stream, right?

18:13:31 [timbl]

Do you have to traverse the whole tree for every document?

18:13:50 [timbl]

So it is linear in the total number of nodes?

18:25:12 [oshani]

timbl, pushback on Tab is designed to do updates through SPARUL to the DERI endpoint. Then that updates to the Twitter API via their PB Write wrapper

18:25:19 [oshani]

at least that's the plan

18:25:27 [oshani]

and re: RDFa parsing

18:25:40 [oshani]

yes I travel the whole DOM tree

18:25:51 [oshani]

not sure what you mean by "but stream"

18:26:52 [oshani]

Fatih mentioned of a pull parsing model like SAX... but I am not sure whether we can use it here

18:27:01 [oshani]

but I guess it's worth investigating

21:10:49 [timbl]

charles2 .. hmm a triple has subject() and predicate() and object() mthods

21:11:26 [timbl]

oops am i thinking of js orpython

21:11:45 [charles2]

timbl: i can try it and see if it works

21:12:06 [timbl]

been programming a little in python

21:13:59 [charles2]

its a great language. Unfortunately, I dont think those methods work on the returned information.

21:14:30 [timbl]

Sorry hte js and py interfaces are diferent :-(

21:15:03 [charles2]

i tried to get avatar information off of my identi.ca account rdf and i got this so far: <http://identi.ca/user/57496> <http://rdfs.org/sioc/ns#avatar> <http://theme.identi.ca/identica/default-avatar-profile.png> .

21:15:20 [charles2]

i suppose i could split on spaces and take the third option

21:15:32 [charles2]

but i wasnt sure if there was a less hackish way to do it

21:16:38 [timbl]

In js the subjcet predicat e and object are properties not functions

21:18:20 [charles2]

okay, so do I just split this triple over the space then?

21:18:34 [timbl]

charles2, the basic RDF classes are in http://dig.csail.mit.edu/2005/ajar/ajaw/js/rdf/term.js

21:18:55 [timbl]

e.g. function RDFStatement(subject, predicate, object, why) {

21:18:55 [timbl]

this.subject = makeTerm(subject)

21:18:56 [timbl]

this.predicate = makeTerm(predicate)

21:18:56 [timbl]

this.object = makeTerm(object)

21:18:58 [timbl]

...

21:20:21 [timbl]

But you probably want to query the knowledge base for give subnect and predicate, like kb.any() as used in http://dig.csail.mit.edu/2005/ajar/adr/book.js

21:20:26 [timbl]

as an example.

21:20:41 [charles2]

I am not sure I understand how to connect what understand so far with that.

21:21:30 [timbl]

icon = kb.any(kb.sym('http://identi.ca/user/57496'), SIOC('avatar'))

21:21:47 [charles2]

oh interesting!

21:22:16 [charles2]

so that is the same as using the foaf inside of kb.any

21:22:50 [timbl]

where SIOC = Namespace("http://rdfs.org/sioc/ns#")

21:23:33 [timbl]

SIOC and FOAF are ways of abbreviating long URIs in the code. They return RDF symbol objevcts -- RDF graph nodes more or less.

21:24:02 [timbl]

These RDF terms can be literals too. They are passed all over the RDF APIs.

21:24:19 [lkagal]

lkagal (n=lkagal@30-6-179.wireless.csail.mit.edu) has joined #dig

21:25:12 [charles2]

interesting. okay I think i understand that

21:25:19 [charles2]

thank you :)

21:25:52 [timbl]

kb.any(s,p) looks for any o such that {s p o} is on kb.

21:26:17 [timbl]

Similarly kb.any(undefined, p,o) looks for an s.

21:26:30 [timbl]

your elcome .. sporry not better doc

21:27:52 [timbl]

There was some attempt to use javadoc to generate some documentation at one point.

21:30:39 [charles2]

that would be pretty fancy

21:42:10 [charles2]

should FOAF and SIOC already be defined? I had to use var foaf = tabulator.ns.foaf for foaf and there wasnt a soic in the tabulator.ns object

21:49:34 [fuming]

fuming has quit ()

22:03:32 [oshani]

charles2, yes SIOC is not defined in Tab

22:03:58 [oshani]

but you can give it a namespace as Tim had suggested

22:05:54 [charles2]

oshani: the javascript seems to like Namespace("foo") but i dont know what to do with it after that

22:08:23 [oshani]

Namespace("foo")?

22:08:44 [oshani]

well, namespacing is just a convenience method IMHO

22:08:59 [oshani]

so you could do SIOC = Namespace("http://rdfs.org/sioc/ns#")

22:09:10 [lkagal]

lkagal has quit ()

22:09:26 [oshani]

and then use SIOC("avatar")
