We propose a novel method for Web page grouping based only on hyperlink information. Because of the explosive growth of the World Wide Web, page grouping is expected to provide a general grasp of the Web for effective information search and netsurfing. The Web can be regarded as a gigantic digraph where pages are vertices and links are arcs. Our grouping method is a generalization of decomposit...
The World Wide Web may be viewed as a gigantic market for information. In this market there are producers (authors) and consumers (readers) and the currency for information is attention. In this paper we examine the distribution of attention across the World Wide Web. Through study of the habits of web users, we conclude that the currency of attention is highly concentrated on a relatively smal...
Search facilities are vital for folksonomy (or social tagging mechanism) based systems. Although these systems allow great malleability and adaptability, they also surfer from problems, such as ambiguity in the meaning of tags, flat organisation of tags and some degree of unstabilising factor on consensus about which tags best describe some certain Web resources. It has been argued that folkson...
The PageRank method is used by the Google Web search engine in computing the importance of Web pages. Two different views have been developed for the interpretation of the PageRank method and values: (i) stochastic (random surfer): the PageRank values can be conceived as the steady state distribution of a Markov chain, and (ii) algebraic: the PageRank values form the eigenvector corresponding t...
We examine how three different communication processes operating through social networks are affected by homophily – the tendency of individuals to associate with others similar to themselves. Homophily has no effect if messages are broadcast or sent via shortest paths; only connection density matters. In contrast, homophily substantially slows learning based on repeated averaging of neighbors’...
Modern, off-the-shelf smartphones provide a rich set of possible touchscreen interactions, but knowledge-based authentication schemes still rely on simple digit or character input. Previous studies examined the shortcomings of such schemes based on unlock patterns, PINs, and passcodes. In this paper, we propose to integrate pressure-sensitive touchscreen interactions into knowledge-based authen...
At the end of the 20th century, access to information provided by the World Wide Web (WWW) is changing as never before. The fast availability of current medical literature and the availability of tools for easy access to information, as well as for the easy production of information, have confronted research physicians, scholars, and students with new kinds of problems, many of which concern us...
In patients with repeated exposure to cold water, such as cold water surfers and kayakers, the reactive exostoses can occur in the external auditory canal. The external auditory canal exostoses are multiple, benign bony growths. They can cause external auditory canal stenosis, leading to repeated otitis externa and potentially conductive hearing loss. It is vital to consider this entity in susc...
A previously healthy 32-year-old man developed acute onset of lower extremity weakness (American Spinal Injury Association [ASIA]–motor L2-S1, grade 2/5), T8 sensory level, and loss of bowel and bladder control (ASIA Impairment Scale [AIS] C) while surfing. The patient was a novice surfer and recalled a prolonged period in prone hyperextension. MRI spine was consistent with surfer’s myelopathy,...
