Lada Adamic's Keynote Address

Markus Strohm has written a great blog entry liveblogging about Lada Adamic's keynote today on The Social Hyperlink, thanks Markus!

ht09, social hyperlink

Stanford started with the social web and club nexus, orkut was started. From online profiles you can find social patterns and discover links between people in hyperlink structure called social hyperlinks.

Session 1: Hypertext Structure and Usage

This session is being chaired by Peter Brusilovsky called Hypertext Structure and Usage. The first presenter is Mark Bernstein from Eastgate Systems. This track session is called the Systems track. Mark is talking about On Hypertext Narrative which the paper is based on his book "Reading Hypertext". We want hypertext to do what we cannot do in print. Hypertext tells a story, and has a plot. Plot, not story is where we find meaning. Little Red Riding Hood is the first social software, according to Mark. When do we tell the reader that the wolf has run ahead and eaten grandma? We have four kinds of links. Stretchtext with no navigation (or at least no departure) is about replacing a piece of hypertext with some other hypertext, essentially "stretching" the text. Our business is about varying plot, not varying story. Text stays itself, electronic text replaces itself.

The second paper is on Bringing Your Dead Links Back to Life. They developed PageChaser, a system to find new locations of moved Web pages which is part of the WISH project. So they asked a question: What's wrong with Google? It doesn't work becuase it needs index in advance, keyword matching and we don't know where the page is. PageChaser uses location bias and link authorities. They developed comprehensive set of heuristics for finding likely places, which many other researchers do not focus on the location factors, but just focus on broken links. Very interesting and relevant work.

Day 2 of Hypertext 2009 Opening Session

After some technical difficulties, the Hypertext conference has started! There was approximately 31% acceptance rate which is in line with previous Hypertext conferences. There will be an ACM Student Research Competition which has 13 posters and there will be a session tomorrow from 4:45 to 6:05 pm, with winners announced at closing tomorrow at 6:10 pm. This competition is sponsored by Microsoft Research.

At noon, there will be a pitch or madness session for the posters and demos, all presenters have to speak for just one minute. The posters and demos session will happen at 6:10 to 7 pm in the A foyer and Room (Sala) B. The social dinner is at Societa Canottieri Caprera, Corso Moncalieri 22 at 8:30 pm. There will also be awards session Douglas Englebart and Ted Nelson awards for best papers. There are social tools for Hypertext 2009, please see this URL, use #ht09 for Twitter posts, ht09 tag for Flickr photos, and you can use Nokia Friend View on your phone for location-based Twitter-type posts.

Hypertext 2010 will be in Toronto, Canada from June 14-17, 2010. There will be a SIGWEB Town Meeting today at 2:10 pm in Sala A on the report on SIGWEB.

It's Day 2 of Hypertext, with keynote speaker Lada Adamic talking about the Social Hyperlink http://ping.fm/HNktu

Workshop on Web 3.0: Semantic Web and Web 2.0

After lunch, it is now for the second set of workshops, the first one is the Workshop on Web 3.0 Semantic Web and Web 2.0. Web 1.0 was just simply linking content, Web 2.0 is user-generated and involved a social change. But computers do not understand data. So Web 3.0 will be driven by technological changes and linking data is the power of Web 3.0. In Web 1.0, there is a producer and consumer, Web 2.0 there are a linkage of people which can be producers or consumers. There is a nice video on Web 2.0 that was shown.

The first paper in the workshop is on UbisEditor 3.0. It is about combining user modeling and ubiquitous computing with Web 3.0. UbisEditor 3.0 has ontologies that are used to drive the user modeling, there is collaborative ontology editing and user-created personalized ontology view. They visualize ontologies using Ajax-based trees.

The second paper in the workshop is on annotation system that uses dialogues in the user-generated content process. From the dialogues, natural language processing is used to extract the semantics and to verify the semantics, we can ask questions. But then asking the questions, is that too much burden on the user?

The third paper in the workshop is evaluating collaborative filtering algorithms for recommending articles in CiteULike, where they use classic collaborative filtering algorithms to find similar tags and users for recommendations. They then did a user study to see if the user found the tag relevant for the resource (in this case the cited article).

The next presentation in the workshop is on Working the Crowd: Design Principles and Early Lessons from the Social-Semantic Web. The InPhO project involves extracting semantics from the text and then presenting it to users, to rate its relevance over another term.

Workshop on Tagging in Dynamic Communities

This is the first workshop of Hypertext 2009, right now the speaker is talking about tagging recommendations using BibSonomy. BibSonomy is a citing bibliography system for citing links and attaching tags to them (like delicious), however this is more similar to CiteULike. In BibSonomy, they have implemented clicklogging to analyze every click that users go to while in BibSonomy to look at their navigation patterns. Clicklogging is used to measure user acceptance of various features such as what recommended tags the user used and to flag users as spammers. They have collected 0.5 million records in 7 months.

The BibSonomy system also has community and personalized ranking to see similar users with similar interests. People can store the links of those users that are similar to them. A question that was arised is whether tag recommendations are good or not.

just finished putting up my poster and getting rfid tag!

if you have a nokia s60 phone, use friend view a service from nokia research center, add hypertext2009 from http://ping.fm/i3ckx

Set up time for posters and demos from 9 am to 10:30 am at Villa Gualino (A foyer /B/C), then workshops: http://ping.fm/5uCdw

Well folks, there is only one and half more days until the Hypertext conference begins! See you all in Turin and have a safe trip there.

Only less than a month left before Hypertext starts on June 29!
