Hypertext 2009

ht09Fil Menczer is one of the organizers of Hypertext 2009, the 20th ACM Conference on Hypertext an Hypermedia. The conference will be held June 29-July 1 at the Villa Gualino Convention Centre, on the hills overlooking Torino, Italy. Hypertext 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. With a 70% increase in submissions, Hypertext 2009 will have a strong and diverse technical program covering 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. The conference will also feature demos, posters, a student research competition, four workshops, and keynotes by Lada Adamic and Ricardo Baeza-Yates.

Informatics team finds simple rules that explain universal laws of written text

Similarity Cloud for 'mac' vs 'pc'

Alessandro Flammini and Filippo Menczer, along with M. Ángeles Serrano from the University of Barcelona, have authored a paper entitled “Modeling Statistical Properties of Written Text” that has been published in the PLoS One. The paper introduces and validates a generative model that explains from simple rules the simultaneous emergence of patterns of written text observed in many languages. The paper focuses on the well-known Zipf’s law of word frequencies, as well as additional patterns such as Heaps’ law of word diversity, the bursty nature of rare words, and similarity among documents. Through their model, the researchers found a connection between word burstiness and the topicality of text. In addition, they identify dynamic word ranking and memory across documents as key mechanisms to explain the organization of written text. The semantic similarity between topics, which is one of the features that the model aims to explain, is visualized by the Similarity Cloud, an online tool developed by computer science graduate student Mark Meiss. The model developed by the researchers and the findings of this paper could lead to improved techniques for identifying key terms that capture the topics of a Web page, which is crucial for matching search queries to relevant results and ads.

NSF award to fund research on the social Web

givealinkFil Menczer recently received a $500,000 grant from the National Science Foundation to investigate the Social Integration of Semantic Annotation Networks for Web Applications. The project brings together complex networks and Web mining techniques to develop a new generation of search engines and collaborative Web applications such as GiveALink.org. The researchers will leverage existing annotations from users (such as the bookmarks they already maintain on their browsers) and elicit new ones through useful tools and games. The research will lead to a framework for building and maintaining socio-semantic networks of relationships between, and among, users, tags, and Web sites. In the end, these networks will improve social Web applications such as search, recommendation, spam detection, and exploratory navigation interfaces. More…
