The third session is on Adaptation, with the first paper on Providing resilient Xpaths for external adaptation engines. The author is talking about using adaptation rules to specify which elements the adaptation is done that affects the page. They use XPath expressions to select the contents that will be adapted.
The second paper is on The Influence of Adaptation on Hypertext Structures and Navigation by Vincius Ramos and Paul de Bra. They use the AHA framework which is adaptive technique for hypertext and uses annotation/hiding and using coloring links. Bad links point to non-recommended concepts and are in black, whereas good links point to recommended concepts.
The third paper is on The next generation Authoring Adaptive Hypermedia: Using and Evaluating the MOT3.0 and PEAL tools by Jonathan G K Foss and Alexandra I Cristea. There is the concept of separation of concerns where you want to separate adaptive content from static content for reusability and flexibility. Adaptive hypermedia looks into user modeling and how to use that and presentation models. They have created MOT3.0, a framework system that allows for Powerpoint and wiki import into the adaptive hypermedia framework. They also have PEAL which can be used for labelling code fragments. You can try out their systems for MOT3.0 and PEAL.

Second session on Recommender Systems
The second session on Recommender Systems starts with the first paper on Automatic Construction of Travel Itineraries using Social Breadcrumbs by Munmun De Choudhury, Moran Feldman, Sihem Amer-Yahia, Nadav Golbandi, Ronny Lempel, and Cong Yu. They create these travel itineraries by taking photo streams from the Flickr dataset that map the photo with the city, then extract candidate POIs using the Yahoo! Maps API, then segment the photo streams to created timed paths to form the travel itineraries. They create the POI graph from this. They compare their automated travel itineraries with real itineraries using Amazon Mechanical Turk. The extensive survey-based user studies on Amazon Mechanical Turk gave promising results against bus tour companies' itineraries.
The second paper is on Speak the Same Language with Your Friends: Augmenting Tag Recommenders with Social Relations by Kaipeng Liu and Binxing Fang. Their proposed graph is to add edges between users and resources in addition to users linked to tags and tags linked to resources. They use random walk-based similarity measures. They compare personalized-CF with User-CF and showed that the proposed Personalized-CF algorithm with MFA as similarity measure performs best.
The third paper is Connecting Users and Items with Weighted Tags for Personalized Item Recommendations by Huizhi Liang, Yue Xu, Yuefeng Li, and Richi Nayak. The problem is that we have a tag quality problem, there is semantic ambiguity, tags could be personal and there are synonyms of tags that mean the same thing. Their proposed apprach is to use the multiple relationships of tagging. Usually only 2 dimensional relationships are used (user-item, user-tag, and item-tag), but in actuality there are three dimensional relationships of user-tag-item relationship: (userXtag)-item mapping, item-(userXtag) mapping. But what about user-(itemXtag) mapping?

First session: Information Searching
The first paper from the conference program is on Is A Good Title? This paper looks into is there a way to name a URI to give a better title that will help in retrieval of search results. Many times, when you enter a search term, the URIs provided are not the relevant results. The author mentions about title evolution and gave the example of Sun.com. How much do titles change over time? They analyzed their title performance prediction but didn't find any new evidence that a page of a page that has a title of more than 24 terms is most likely spam.
The second paper is on Parallel Browsing on the Web by Jeff Huang and Ryan White. Browsers have tabbed browsing and they look into parallel browsing and gathered data from Internet Explorer 8. This was joint work with Microsoft Research. From their results, they found that users don't visit more pages when using more tabs.
The third paper is on A semiotic approach for the generation of themed photo narratives by Charlie Hargood, David Millard, and Mark Weal. According to Charlie, narratives surround us and we need to create systems to accommodate these narratives. They take a semiotic approach where semiotics are the study of signs and how we understand them. They did an experiment to evaluate the effectiveness of the Themed Montage Builder. The Themed Montage Builder (TMB) is a prototype using definitions in terms of model to generate themed montages, eg. from Flickr images. They found that the TMB shows a slight improvement. It is interesting how this approach could be used to create narrative from travel blogs.
The last paper in this session is The Impact of Bookmarks and Annotations on Refinding Information by Ricardo Kawase, George Papadakis, Eelco Herder, and Wolfgang Nejdl. They created an annotation system called SpreadCrumbs which is a social annotation system and it supports hypertrails which is a path of links. They then did experiments to test their SpreadCrumbs system compared to Delicious for bookmarks and annotations. The results showed that it was faster for the group that used annotations and SpreadCrumbs to find the information and outperform search in terms of performance.

First day of Hypertext conference - Andrew Dillon keynote
Today is the first day of the Hypertext conference. After a great day of workshops last night and open bar (unheard of at conferences according to Chair Mark Chignell) at the reception, the Hypertext conference officially starts today. Andrew Dillon is the keynote speaker talking about As We May Have Thought. Andrew is talking about how the trend in Hypertext is declining while web and web science are increasing. Is there a need for a new discipline? Web Science attempts to take an interdisciplinary approach, just like HCI does as well, but should we do that?
Information and computer science has started and it keeps going. Hypertext, hypermedia, no matter what your area of focus, it is one more point in the timeline in the sharing of information. Andrew says that according to Steve Jobs of Apple, "nobody reads anymore". Civilization is shifting as information explodes, computing is moving from calculation to augmentation. We are at a moment of profound change in the ecology of information. Are we going backward?
From Jakob Nielsen (usability expert), we haven't changed that much for usability. Nielsen has usability guidelines for web sites, even though his web site is not that usable. In fact Nielsen came out of Hypertext into HCI. The best way to understand in the world now is that technology is used is the natural human condition. There was this 500 year period during Gutenberg where oral culture was shifted to written culture. Is the web a return to pre-Gutenberg era?
According to Andrew, the human is the key, there is too much emphasis on search, location and retrieval and too little emphasis on longitudinal outcomes.
Andrew ended with the quote from Vannevar Bush: "A record if it is to be useful..must be continuously extended, it must be stored, and above all it must be consulted." (Bush, 1945)

Social media applications such as blogs, microblogs, wikis, news aggregation sites and social tagging systems have pervaded the web and have transformed the way people communicate and interact with each other online. In order to understand and effectively design social media systems, we need to develop models that are capable of reflecting their complex, multi-faceted socio-technological nature. While progress has been made in modeling particular aspects of selected social media applications (such as the architecture of weblog conversations, the evolution of wikipedia, or the mechanics of news propagation), other aspects are less understood.

2. Rhetorical and Semantic Possibilities of Links: Cultural and Literary Applications of Links
Deena Larsen
Ann-Barbara Graff
Contact: deenalarsen@yahoo.com
Mark Bernstein has written that the link is “the most important new punctuation mark since the comma.” More than that, the link actually conveys meaning. But how do people use links to communicate ideas?
This workshop is designed to uncover the semantic value of the link and its potential rhetorical effects. We want to know what has been the cultural, literary, rhetorical, and semantic impact of the link to date, and what future effects can we anticipate and bring about. We will explore the link in hands-on exercises and examinations of electronic literature and other hypermedia examples. Ideally, the audience will be broad, composed of anyone who wants to develop a further understanding of this tool.

3. Critical Code Studies
Mark Marino
Contact:
markcmarino@gmail.com
Recent movements in technocultural studies have sent critics “under the hood” of digital texts. This workshop examines the code that produces the creative digital artifacts in order to develop a rich sense of the artistic and social implications of particular coding choices. A primary goal is to develop the ways of speaking about the code to complement the kinds of analyses that have typified Hypertext.

Contact:
riverady@gmail.com
The goal of this workshop is to identify opportunities to use hypertext, annotation, and social computing in making better use of emerging sensor and information technologies in healthcare. We expect that a broad range of research approaches will be relevant to this workshop, with issues including the role of hypertext in the design of EHR systems, and best practices in the design of annotated and hyperlinked health applications.
