Semantic grounding of tag relatedness in social bookmarking systems

by Ciro Cattuto, Dominik Benz, Andreas Hotho, Gerd Stumme - In The Semantic Web – ISWC 2008, Proc.Intl. Semantic Web Conference 2008, volume 5318 of LNAI , 2008
"... Abstract. Collaborative tagging systems have nowadays become important data sources for populating semantic web applications. For tasks like synonym detection and discovery of concept hierarchies, many researchers introduced measures of tag similarity. Even though most of these measures appear very ..."

and analyze several measures of tag similarity: Each measure is computed on data from the social bookmarking system del.icio.us and a semantic grounding is provided by mapping pairs of similar tags in the folksonomy to pairs of synsets in Wordnet, where we use validated measures of semantic distance

A comparison of social bookmarking with traditional search

by Beate Krause, Andreas Hotho, Gerd Stumme - In ECIR ’08
"... Abstract. Social bookmarking systems allow users to store links to in-ternet resources on a web page. As social bookmarking systems are grow-ing in popularity, search algorithms have been developed that transfer the idea of link-based rankings in the Web to a social bookmarking sys-tem’s data struct ..."

as the overlap of the underlying sets of URLs. In the second part, we compare graph-based and vector space rankings for social bookmarking systems with commercial search engine rankings. Our experiments are performed on data of the social bookmarking system Del.icio.us and on rankings and log data from Google

Can social bookmarking improve web search

by Paul Heymann, Georgia Koutrika, Hector Garcia-molina - in Proceedings of the International Conference on Web Search and Web Data Mining (WSDM'08), ACM
"... Social bookmarking is a recent phenomenon which has the potential to give us a great deal of data about pages on the web. One major question is whether that data can be used to augment systems like web search. To answer this question, over the past year we have gathered what we believe to be the lar ..."

Social tag prediction

by Paul Heymann, Daniel Ramage, Hector Garcia-molina - In SIGIR ’08 , 2008
"... In this paper, we look at the “social tag prediction ” problem. Given a set of objects, and a set of tags applied to those objects by users, can we predict whether a given tag could/should be applied to a particular object? We investigated this question using one of the largest crawls of the social ..."

bookmarking system del.icio.us gathered to date. For URLs in del.icio.us, we predicted tags based on page text, anchor text, surrounding hosts, and other tags applied to the URL. We found an entropy-based metric which captures the generality of a particular tag and informs an analysis of how well that tag can

Visualizing Social Bookmarks

by Joris Klerkx, Erik Duval
"... Abstract. Social bookmarking tools are very popular nowadays. In most tools, users tag the bookmarks to describe them. Therefore, it is often hard for users to discover implicit structures between tags, users and bookmarks. We think that this is essential for both end users to discover new bookmarks ..."

In this work, a cluster map visualization application is customized to enable users to explore social bookmarks in the del.icio.us system [5]. The design of the application

Social Bookmarking in the Enterprise

by Michael D Froh, Geoffrey B, Michael D. Braly, Geoffrey B. Froh
"... At the beginning of the project, we had an ex-isting pre-prototype bookmarking system. Our goal was to develop a set of recommendations for improving the user interface and function-ality of the existing system. We began with a user research phase to gauge user perceptions of the problems with finda ..."
Abstract - Add to MetaCart
findings were: Internal search is not effective. (85.7 % were unsuccessful in their use of the system most of the time) Bookmarking in a browser is an important but problematic refindability strategy. (85.2% have bookmarks on more than one machine) Users are become aware of social bookmarking. (77

Conceptual clustering of social bookmarking sites

by A Grahl, Andreas Hotho, Gerd Stumme - In Proc. I-Know 2007 Conference (to appear , 2007
"... Currently, social bookmarking systems provide intuitive support for browsing locally their con-tent. A global view is usually presented by the tag cloud of the system, but it does not allow a conceptual drill-down, e. g., along a conceptual hierarchy. In this paper, we present a cluster-ing approach ..."

Social bookmarking and exploratory search

by David Millen, Meng Yang, Steven Whittaker, Jonathan Feinberg
"... ABSTRACT. In this paper, we explore various search tasks that are supported by a social bookmarking service. These bookmarking services hold great potential to powerfully combine personal tagging of information sources with interactive browsing, resulting in better social navigation. While there has ..."
Abstract - Cited by 29 (6 self) - Add to MetaCart
there has been considerable interest in social tagging systems in recent years, little is known about their actual usage. In this paper, we present the results of a field study of a social bookmarking service that has been deployed in a large enterprise. We present new qualitative and quantitative data

Exploiting social annotation for automatic resource discovery

by Anon Plangprasopchok, Kristina Lerman - In AAAI workshop on Information Integration from the Web , 2007
"... Information integration applications, such as mediators or mashups, that require access to information resources currently rely on users manually discovering and integrating them in the application. Manual resource discovery is a slow process, requiring the user to sift through results obtained via ..."

in response to a query. The recently popular social bookmarking sites, which allow users to annotate and share metadata about various information sources, provide rich evidence for resource discovery. In this paper, we describe a probabilistic model of the user annotation process in a social bookmarking
