Keynote on Day 3: Relating Content through Web Usage by Ricardo Baeza-Yates
Ricardo is VP of Yahoo! Research in Barcelona, Santiago, and Haifa, Israel. He was a PhD student at the University of Waterloo. He also maintains ties with universities in Spain. His talk is on Web Content through Web Usage. He has a book which is the standard in information retrieval. According to Ricardo, web search is no longer about document retrieval, there is now a new breed of search experiences which involve the Wisdom of Crowds behind Web 2.0. Search is evolving more than just documents towards identifying a user's task and task completion. However the challenges are on-line and scalability.
We now have more complete information available in one search such as shortcuts, deep links and enhanced results. But for search, it is content vs. intent, the premise for the user is that they don't want to search, they just want to get tasks done and straight to their answers. We do searching when we don't know what to ask or who to ask. We are now moving from a web of pages to a web of objects. Objects have attributes, they will be missing, noisy, incomplete, but that is ok. Attributes define faceted search. However, the question is how do we get structured objects/attributes? This will come from metadata/semantic web/ontologies, web usage, and building out an open ecosystem.
From the AOL experience, obtaining queries and clicks is private. Crawling the web is expensive. From James Surowiecki, a New Yorker columnist in his 2004 book: Under the right circumstances, groups are remarkably intelligent. So what do you get from the wisdom of crowds? Popularity, diversity, quality and coverage are what we get out. The wisdom of crowds is crucial for search ranking, we use text (web writers and editors), links (web publishers), now tags (web taggers), and what Yates is mentioning next is taking all the queries.
20 years later, the basic ideas of cross references and dynamic links from Frank Tompa in 1988 is still relevant today. Yahoo Research has some demos of their research, one is TagExplorer which is based on tag similarity. How this is done? First, tag mining needs to be classified and tag semantics are done using WordNet. Yates showed a demo in TagExplorer where you can find tags related to locations, subjects and activities based on a query, he gave the example of Torino. Based on this and finding similar pictures, we can tag pictures automatically. We could also suggest tags to people based on a picture, however if you do that in Flickr, this is not folksonomy any more. This would be biased towards the algorithm and that is what we don't want.
We can also do visual annotations by associating text with a visual area which is done in Flickr as well as tagging people in Facebook. Content-based image retrieval is based on first extracting visual features and describing them, and then building a visual vocabulary using k-means clustering. This is an example of combining tagging and visual image retrieval. Besides WordNet, you can also use Wikipedia search and use that to drive the algorithm. By using this, Yahoo Research has created Correlator to find relations in the Wikipedia. Correlator works by retrieving related sentences and ranking them.
The next part of Yates' talk is Web Usage. We can use clicks by following hyperlinks, queries that express user interest. For example, if q4 is related to q3 because the words in the pages are similar and because the user clicked it. We can see what people are looking for, mapping queries to ODP. You can do hierarchical clustering on the graph (Francisco, Baeza-Yates and Oliveira).
So what are some of the open issues? Data volume versus better algorithms, explicit versus implicit social networks (are there any fundamental similarities), how to evaluate with (small) partial knowledge, and user aggregation vs. personalization. We have a virtuous cycle and improve the web.
So now it's questions. First question was about how Yahoo Research's work on tagging and search compares with Wolfram Alpha. Yates answered that the two come from different ends of the spectrum. Yahoo Research is making some of their datasets like Yahoo Answers available to researchers to use.

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
ht09, social hyperlink
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.

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.

** Keynote by Ted Nelson! **
Workshop on NEW FORMS OF XANALOGICAL STORAGE AND FUNCTION
at the ACM HYPERTEXT Conference 2009
June 29th, Turin, Italy
Workshop: http://ping.fm/FjtOv
Main Conference: http://www.ht2009.org/
**********************************************************************
*** Keynote speaker: Ted Nelson ***
***Extended Submission Deadline --- April, 19th***
**********************************************************************
NEWS
====
- We are pleased to announce a keynote by Ted Nelson!
- The deadline for paper submission is extended to April, 19th.
WORKSHOP THEME AND GOALS
========================
Xanalogical storage and transclusions were proposed at the earliest days
of modern hypertext, in order to create a global document space where
users can freely share, customize and reuse content. A Xanalogical
document can be thought of as a virtual list of linked text chunks, which
can be permanently identified, retrieved and aggregated within the system.
Rich and fine-grained information about who, when and how the chunks were
edited allow users to surf and manipulate inter-connected documents in
powerful yet safe and ways.
The World Wide Web moved away the original Xanadu vision. However, new
forms of Xanalogical editing are being discovered. Active participation of
users in writing and linking web content is dramatically increasing.
Blogs, wikis and mashups all prove we are going towards (or probably we
are already into) a new Web conceived as a writing platform rather than as
a reading one. Such active participation was part original vision of the
hypertext pioneers. The depth and breadth of involvement is more than a
social trend -- it is supported by many new applications, standards and
services available today.
How is the time to find synergies between the original Xanalogical vision
and the recent developments in the WWW. Some new ideas and new prototypes
have been recently presented by the hypertext community. This workshop
will be a place to gather researchers and professionals interested in
Xanalogical models and Web editing and linking, in order to foster the
discussion, provide new research directions, and how other experts their
recently developed systems and models.
FORMAT
======
The workshop will run a half day, and be divided in two equal parts, in
order to emphasize both the theoretical/algorithmic aspects and the
practical applications of the Xanalogical model. Ample space will be
given to peer discussions and brainstorming about the results of the
presentations and the ideas brought forth by participants.
INTENDED AUDIENCE
=================
Researchers in hypertext, Web technologies, Xanalogical models,
collaborative editing, distributed systems, etc.
IMPORTANT DATES
===============
* Submission: Monday 19 April 2009 (Extended deadline!)
* Notification: Monday 10 May 2009 (Extended deadline!)
* Final copy: Wednesday 25 May 2009 (Extended deadline!)
* Workshop: Monday 29 June 2009
SUBMISSIONS
===========
Authors must submit an electronic copy of their proposed articles (in
PDF) via email to XanaWorkshopHT09@cs.unibo.it. Articles should be
between of 2 and 5 pages in length, when printed using the official ACM
templates (http://ping.fm/jfazE).
PROCEEDINGS
===========
The outcome will be published in the on-line Hypertext 2009 Workshops
proceedings and, given enough interesting contributions, may contribute
to forming the content of a special issue of a journal in a related area.
We will also consider multiple documents connected as a hypertext so long
as the total length is comparable to that for the printed versions, and
the system needed to interact with and display the hypertext is widely
available (to help with refereeing).
At least one of the authors of an accepted submission must register to
the main conference and participate in the workshop.

Second CALL FOR PAPERS
Hypertext 2009
The Twenty-First ACM Conference on Hypertext and Hypermedia
http://www.ht2009.org/
June 29th - July 1st, 2009, Torino, Italy
SCOPE
-----
The ACM Hypertext Conference is the main venue for high quality
peer-reviewed research on "linking." The Web, the Semantic Web, the
Web 2.0, and Social Networks are all manifestations of the success of
the link. The Hypertext Conference provides the forum for all research
concerning links: their semantics, their presentation, the
applications, as well as the knowledge that can be derived from their
analysis and their effects on society.
Hypertext 2008, held in Pittsburgh, was a real success. The number of
submissions and attendees was up, a successful Student Research
Competition took place, and a rejuvenated social linking track added
new ideas and connections to the traditional core of the conference.
IMPORTANT DATES
---------------
* Technical tracks paper submission deadline: February 2nd, 2009
* Notification to authors: March 16th, 2009
* Camera-ready (final papers to ACM): April 6th, 2009
LOCATION AND DATES
------------------
Hypertext 2009 will be held from June 29th to July 1st at the Villa
Gualino Convention Center, on the hills overlooking Torino.
The capital of the Piedmont region, Torino lies at the foot of the
Alps, the majestic mountains that hosted the 2006 Winter Olympics.
First the capital of the Kingdom of Italy, then one of the European
centers of baroque, today Torino is a dynamic city known for its
industry, art and culture, sports, research and education, and
cuisine.
The timing of Hypertext 2009 provides an excellent opportunity to
visit Italy in conjunction with the International Conference on User
Modeling, Adaptation, and Personalization in Trento (UMAP 2009 -
http://umap09.fbk.eu/), and the International Workshop and Conference
on Network Science in Venice (NetSci 2009 - http://www.netsci09.net/).
PROGRAM
-------
Hypertext 2009 will feature two stellar keynote speakers: Lada Adamic
(University of Michigan) is a noted scholar of social networking and
the winner of the 2008 Engelbart Award; Ricardo Baeza-Yates is
Vice-President of Yahoo! Research for Europe and Latin America,
leading the labs in Spain, Chile, and Israel.
In the conference technical program, professionals from academia,
industry, and the media will present innovative ideas and tools
exploiting the broad range of links increasingly connecting people,
information, communities, and structures. Research topics will be
organized into three tracks:
track 1. Information Structure and Presentation (Chairs: Peter
Brusilovsky and Cristina Gena)
track 2. People, Resources, and Annotations (Chairs: Andreas Hotho and
Vittorio Loreto)
track 3. Hypertext and Community (Chairs: Mark Bernstein and Antonio Pizzo)
TRACK 1: INFORMATION STRUCTURE AND PRESENTATION
-----------------------------------------------
Chairs:
* Peter Brusilovsky, University of Pittsburgh (USA)
* Cristina Gena, University of Torino (Italy)
The information structure and presentation track represents a
multitude of topics, which were traditionally represented at ACM
Hypertext Conferences. The track program targets formal study of
scholarly, structural, sculptural, spatial, open, dynamic and adaptive
or any other type of hypertext (or Web-based Information System). This
track also focuses on how hypertext approaches and technologies can be
applied to structure and present information in diverse domains, and
how hypertext techniques can be exploited in classical and advanced
applications. The aim of this track is to bring researchers together
to discuss models, architecture, applications, properties, or theory
in general, about hypertext and hypermedia. Topics for consideration
include:
* Hypertext models
* Spatial hypertext
* Information structuring
* Hypertext and knowledge management
* Self-organized hypertext
* Personal information organization
* Intelligent hypertext and link generation
* Navigation support
* Open hypertext
* Web and hypertext link analysis
* Dynamic and adaptive hypertext
* Hypertext and web engineering
* Interfaces and interaction with hypertexts
* Faceted browsing
* Social navigation
* Hypertexts supporting Web-based collaboration
* Hypertext and recommender systems: the role of link in recommendations
* Hypertext applications in everyday devices (TV, mobile phone, on
board car service, etc.)
* Educational hypertext and hypermedia
* User evaluations of hypertext application
* Hypertext and cultural heritage
* E-books, kiosks, e-commerce, e-tourism
* Hypertext application in medical and health systems
For additional information on the track and the Program Committee,
please visit http://www.ht2009.org/track1.php
TRACK 2: PEOPLE, RESOURCES, AND ANNOTATIONS
-------------------------------------------
Chairs:
* Andreas Hotho, University of Kassel (Germany)
* Vittorio Loreto, Sapienza University of Rome (Italy)
One of the most exciting recent developments in Web science is the
rise of social annotation, by which users can easily markup other
authors' resources via collaborative mechanisms such as tagging,
filtering, voting, editing, classification, and rating. These social
processes lead to the emergence of many types of links between texts,
users, concepts, pages, articles, media, and so on. We welcome
submissions on design, analysis, and modeling of information systems
driven by social linking. Topics of interest include but are not
limited to:
* Applications to search, retrieval, recommendation, and navigation
* Explicit vs. inferred social links (e.g. mining query logs)
* Integration of different social networks (e.g. links between blogs
and bookmarking systems)
* Socially induced measures of similarity, relatedness, or distance
* Co-evolution of social, information, and semantic networks
* Analysis of the structure and the dynamics of social information
networks
* Behavioral patterns of social linking
* Linguistic analysis of social annotation spaces
* Formal and generative models of social annotation
* Unstructured vs. structured social knowledge representations
* Implementation and scalability of social link representations
* Automatic and user-based evaluation
* Emergent semantics in social networks
* Robustness against spam and other forms of social abuse
* Design of collaborative annotation mechanisms
* Critical mass and incentives of social participation (e.g. games)
* User interfaces for collaborative annotation
For additional information on the track and the Program Committee,
please visit http://www.ht2009.org/track2.php
TRACK 3: HYPERTEXT AND COMMUNITY
--------------------------------
Chairs:
* Mark Bernstein, Eastgate Systems, Inc. (UK)
* Antonio Pizzo, University of Torino (Italy)
The Hypertext and Community track will explore, examine, and reflect
upon social cyberculture in electronic media, ranging from literary
fiction and creative scholarship to blog and microblog networks,
social sites, games, auctions, and markets. Topics will include:
* Hypertext literature
* Theory and practice of expression in wikis, weblogs, and social spaces
* Personal journals, weblogs, and social media
* Net art, literary hypertext, interactive fiction, and games
* Behavioral patterns of social linking
For additional information on the track and the Program Committee,
please visit http://www.ht2009.org/track3.php
