  295. RT @jokinc #www2009, as more relevant the snippet is, more the people clicks on it, even if it provides all the needed info

  296. @ivan_herman unfortunate name though as there is a SiLK for network analysis:…
  297. @mhausenblas would you use #www2009 as a tag instead of #www09? many people are following the activities by searching for www2009

  318. #searchmetrics #www2009 on to profiling URL ages in search engines. Reflects crawler quality among others
  319. @twitter RT @heycam nice idea for a service: a twitter account that detects tweet language and retweets translated to another language

  320. So many Spanish tweets at #www2009 that I’d like to read. Where is twitter translator when you need one?
  321. #searchmetrics #www2009 measuring coverage and diversity in search engines. Many approaches, some yet to be published, no winning strategy

  332. #searchmetrics #www2009 indirect use of user clicks by way for differences in expected #DCG between two engines; depends on relevance model
  333. @tommyh similarly at @searchmetrics plenty of Q&A

  334. #searchmetric #www2009 balanced interleaving combination of results is a good method to compare engines based on direct user clicks
  335. RT @gaedke #tWWWeetLunch is a yes! Anyone else?

  336. too much “follow” spam. Please post at least 1 post with #www2009 before following to identify yourself as interested in the conference.
  337. #searchmetric #www2009 nDCG and q-measures are best for comparing search engines in practice

  338. #searchmetric #www2009 Graded version of #bpref is #rpref – a cumulative gain approach, as recent as 2007!
  339. #searchmetric #www2009 Kandall Binary preference #bpref works with binary preference judgements (yes/no) – easier for judges

  343. #searchmetric #www2009 mean average precision (#MAP) is the next metric on the list. Shows averages as a single number

  344. #searchmetric #www2009 the most basic metric is precision, recall, and their combination as f-score. As precision varies, f-score is a graph
  345. #searchmetric #www2009 hard to compute recall but can be estimated by sampling

  346. #searchmetric #www2009 still going over the basics – precision, recall, F-measure
  347. Yahoo is talking about Search Engine Metrics @ #www2009. The intro was pretty basic but comprehensive.
