Mixed Markup and Web Applications - Dean Jackson
posted by libby at 2004-05-19 21:01 (+)

edd: transcription of slides welcome, as they can't be viewed by most people.
libby: e.g. XHTML plus SVG plus mathml; xhtml+ xforms; general: your own xml formats
libby: browser support isn't there yet - that's why dean wrote oen browser - in order to demo these things
libby: oooo
libby: wheee
libby: xhtml in SVG - sideways video, masking video...useful for dvds
libby: mobile people want to have MMS with video, text etc; interop very important for them
libby: xhtml/svg/mathml in mozilla (not on mac)
libby: authoring, validation with DTD difficult
libby: what media types are these mixed documents?
libby: possibly - w3c write a document on how to use subsets of certin langauges together, and give it a media file
libby: also: event handling, bubbling up, custom events; document time-line - who controls it? who owns the canvas? - needs a plug in architecture
libby: styling - does svg style overwrite html style - scoping stylsheets not possible atm
libby: webapplications - Bert Bos's position paper for the webapps workshop
libby: webapps: hard to identify; one or more or less of: smaller than a real app; interactive; scripted; hosted by something (sometimes a browser); downloaded over a network
libby: need protocols: get, post, soap, xmlrpc, sockets...
libby: filesystem access; xml processing, xpath, timing and custom events
libby: user interfaces... XUL..?
libby: backwards compatible? dev independence - extracting app behaviour from platform specific details? security, authentication, writing to disk; packaging to user
libby: webapps workshop on web apps and compound documents - lots of papers, e.g. mobiles and telecom operators
libby: submissions have closed, but ask dean
libby: strong market demoand, lots of issues; time to tackle the mess
libby: should be very interesting in a year's time - get involved, join w3c, attend the workshop
libby: related is the XBL stuff; joint taskforce ..

Impact of Web Search Engines on Page Popularity
posted by pshab at 2004-05-19 21:00 (+)

pshab: starting point that users not see what is on the web but what is biased by what is on the search engins
pshab: so... is it the case that rich get richer... as popular are hit more?
pshab: aim to find out how much bais the search engiens generate
pshab: construced weekly web link graphs... from set of pages 150(?) web sites and immediate neighbours
pshab: partitioned into groups based on popularity 10% sets
pshab: so can see if rich get richer by watching this over time
pshab: graph... shows popular pages get more links - 70% of new liks pointing to top 20%... bottom 60% got hardly any
pshab: used a pagerank metric - shows same trend - wiht popular increasing and unpop getting less popular
pshab: so. yes rich do get richer
pshab: How much of this is due to search engins?
pshab: and thus what degree of bias is caused in the users perception of "the web"
pshab: ... question - what is an ideal way of ranking pages? and compare with how serach engines do it now...
pshab: page quality? but very subjective... need more objective metic
pshab: what is prob that user will like it enought ot make a link to it...? do it for all web users and get them to look at the pages and count votes- a democratic approach
pshab: problme is that all pages dont' have equal cahnce of beign reached by browsing - can't tell difference between quality or lack of discoverabiltiy
pshab: how to measure bias? 1) group users make one group not use engines, another use them compare results
pshab: hard to do in practice - who would want to be in group 1?
pshab: so create a simulation/model - random surfer model V search dominant model and cf. popularity evolution
pshab: explains models... in more detail
pshab: three measures - popularity/visit popularity/awarness
pshab: popularity = quality x awarness of page
pshab: graph of random model surfer 3 phases to maturity of popularity
pshab: relationship between visit popularity and popularity?
pshab: Search dominant model gives a step function? with much longer time to become popular than random model
pshab: !!
pshab: 25 times longer time to maturity
pshab: so study and modeling ... worriesome impact of search engines... need better measures of quality for search engines(? I think - missed that bit of the slide)
