RT @sheilaellen: @robertobelo Your twitter stream has been excellent. Fantastic idea. Hope you’ve had a great time #www2009

#www2009 i thought the index compression talk was good .. but there were no questions asked.
-
#www2009 query processing: reordering of pages can significantly reduce index size per query for most queries
-
@rcostu yes, each piece of information: review, update, event, etc should be accessible individually – makes api and integration more usable
-

#restful #www2009 is paused for lunch. Was informative and easy to follow. I also liked the flexibility of the speaker based on questions

#restful #www2009 POST -> changes state on the server; problem with fault tolerance; not safe to repeat
-
#restful #www2009 PUT -> can be repeated with same outcome ; safe to retry but need to know unique ID of resource
-
#restful #www2009 GET is a “read-only” op -> can be repeated without changing state on server
-
#restful #www2009 many differences between PUT and POST in REST, but not clear enough when to use which
-
@dirkahlers with some planning could’ve been done in facebook maybe … there is an event page, but it’s inactive

RT @gaedke: Attending TUTORIAL at #www2009? Please reply/DM how you like it. As tutorials chair: Did we select tutorials of interest to you?
-
@SeanGolliher no comments about www2009 where?
-
@rcostu yes, this is more of a social event organized by an attendee. It is said to help overcome jet lag.
-
@shaver piece of cake, nothing an espresso can’t fix.
-
highlight of the evening: lightning talks of 1.5 mins from #linkeddata #www2009 dinner participants .. so many interesting and diverse works
-
@taktak mmm sushi .. will you have some hamachi? nigiri, maki, sashimi; it’s all good. count me in! Any good sushi places in Madrid? ja mata
-
@mzurko never did yoga myself. But I heard the event organizer, Pavel, is an expert! If I’m up early enough I’ll give it a try.
-
@mariagrineva at least you did the important stuff in advance. See you soon
-
@dajobe you didn’t drink enough! the beer is good. the wine is good. and there is always coffee
-
@juansequeda so semantic-webbie 😛
-
#ldow2009 #www2009 the dinner is absolutely awesome! the people, the drinks, the food .. love it!
-
#www2009 Pavel is organizing daily yoga sessions 8:00 – 9:00 AM in room San Jose of the conference centre
-
#wicow2009 #www2009 discussions continue at the Novotel’s restaurant 7:30 PM.
-
@kidehen will discuss further today if I make it to free beer
-
#www2009 first day concluded. I’m impressed (the official part). A very long day, however, compared to other events.
-
surprised @ the heated discussion of PageRank efficiency. A. Broder previously said that this is solve – easy & fast #www2009 #ldow2009
-
RT: @tommyh: all the #ldow2009 slides will be online at http://events.linkeddata.or… . some are already, the rest shortly.
-
#ldow2009 #www2009 using pagerank for ranking datasets is interesting, but be aware of link spam; not spam resilient as speaker suggested.
-
@SeanGolliher gracias!
-
@seangolliher explains why I couldn’t find it. Let me know when it’s released. taa @ acm dot org
-
@SeanGolliher sounds interesting. will check it out
-
@gothwin fuelled on coffee and ready for more brain fuels
-
now @ #linkeddata #ldow2009 #www2009
-
it was good finally meeting @gaedke in person and talking about twitter over coffee
-
@besbes worth $14.95?
-
RT @jokinc #www2009, as more relevant the snippet is, more the people clicks on it, even if it provides all the needed info
-
@ivan_herman unfortunate name though as there is a SiLK for network analysis: http://tools.netsa.cert.org…
-
@mhausenblas would you use #www2009 as a tag instead of #www09? many people are following the activities by searching for www2009
-
@gothwin I second that. I think coffee should be available at all time #www2009
-
@gaedke #searchmetrics was pretty good .. should’ve listened more and tweeted less 😛
-
@mariagrineva would love to see your blog search. Are you presenting a paper?
-
#webcentives #www2009 “Varying conclusions from survey data and experimental research” re public vs. private models
-
“if you torture the data long enough it will confess”
-
RT @jahendler you might also encourage use of tag #www2009 (someone could put this in kickoff remarks)
-
now @ #webcentives #www2009
-
the lunch is absolutely fantastic! well done guys
-
caviar for lunch
-
#searchmetrics #www2009 concluded. Off to lunch twwweet
-
#searchmetrics #www2009 big question “What is the best way to manage user attention?”
-
#searchmetrics #www2009 rounded corners are easier on the eyes
-
#searchmetrics #www2009 some practical tips on ‘Presentation aspects and issues”
-
@xamat full disclosure: http://tony.abou-assaleh.net
-
@xamat better unofficial than nothing, wouldn’t you agree?
-
RT @mariagrineva: Who is at www2009, I suggest you to follow @www2009
-
@arkaitz installing. thanks!
-
@gkob vertical search is the future of search, at least until we invent thought readers
-
#searchmetrics #www2009 chicken&egg: how to find undiscovered URLs to test crawler discovery rate?
-
inconvenience: posting updates to #twitter doesn’t fetch new tweets, need to reload manually.
-
#searchmetrics #www2009 on to profiling URL ages in search engines. Reflects crawler quality among others
-
@twitter RT @heycam nice idea for a service: a twitter account that detects tweet language and retweets translated to another language
-
So many Spanish tweets at #www2009 that I’d like to read. Where is twitter translator when you need one?
-
#searchmetrics #www2009 measuring coverage and diversity in search engines. Many approaches, some yet to be published, no winning strategy
-
@tommyh I was actually talking to one of them earlier .. turned out he works at Yahoo
-
@tadejtadej what else is new, eh?
-
@alexgarciac Do tell what the actual news is
-
#searchmetrics #www2009 Query by Content flowchart .. how to estimate coverage in search engines
-
#searchmetrics #www2009 resumes after the coffee break
-
@xamat which tutorial?
-
Talking to creator of www.newsclub.de
-
on to #tWWWeetCoffee
-
#searchmetrics #www2009 is now on break, only 3 mins over schedule. So far so good.
-
ops .. beeing a twitter n00b, just discovered RT meant retweet and not reply-to.
-
#searchmetrics #www2009 indirect use of user clicks by way for differences in expected #DCG between two engines; depends on relevance model
-
@tommyh similarly at @searchmetrics plenty of Q&A
-
#searchmetric #www2009 balanced interleaving combination of results is a good method to compare engines based on direct user clicks
-
RT @gaedke #tWWWeetLunch is a yes! Anyone else?
-
too much “follow” spam. Please post at least 1 post with #www2009 before following to identify yourself as interested in the conference.
-
#searchmetric #www2009 nDCG and q-measures are best for comparing search engines in practice
-
#searchmetric #www2009 Graded version of #bpref is #rpref – a cumulative gain approach, as recent as 2007!
-
#searchmetric #www2009 Kandall Binary preference #bpref works with binary preference judgements (yes/no) – easier for judges
-
#searchmetric #www2009 Discounted Cumulative Gain #DCG is useful for graded relevance feedback, e.g., star rating system
-
#searchmetric #www2009 Mean Reciprocal Rank (#MRR) looks at top relevant results
-
#searchmetric #www2009 for MAP@10, if some queries don’t have 10 results, use R-precision instead.
-
#searchmetric #www2009 mean average precision (#MAP) is the next metric on the list. Shows averages as a single number
-
#searchmetric #www2009 the most basic metric is precision, recall, and their combination as f-score. As precision varies, f-score is a graph
-
#searchmetric #www2009 hard to compute recall but can be estimated by sampling
-
#searchmetric #www2009 still going over the basics – precision, recall, F-measure
-
Yahoo is talking about Search Engine Metrics @ #www2009. The intro was pretty basic but comprehensive.
