BACKGROUND The Internet provides a platform to access health information and support self-management by consumers with chronic health conditions. Despite recognized barriers to accessing Web-based health information, there is a lack of research quantitatively exploring whether consumers report difficulty finding desired health information on the Internet and whether these consumers would like a...

This paper aims to present cartographic rules for the production of paper and electronic navigational charts and main differences in compilation, visualisation and representation of nautical information. Major differences between paper nautical charts and ENC are visualisation of nautical data: colour mixing, resolution of represented nautical objects, human control of display representation an...

The pebble tree automaton and the transducer are enhanced by additionally allowing an unbounded number of “invisible” pebbles (as opposed to usual “visible” ones). resulting automata recognize regular languages (i.e., can validate all generalized DTD's) hence find matches MSO definable patterns. Moreover, when viewed as a navigational device, they lead XPath-like formalism that has path express...

Animals typically have several navigational strategies available to them. Interactions between these strategies can reduce navigational errors and may lead to the emergence of new capacities.

The paper describes a method to extract navigational information from link structure in Blogosphere such as Everything2. The purpose of the method is to support readers of weblogs in selecting hyperlinks from scattered anchor texts in the web pages by providing navigational information. The navigational information consists of hyperlinks that are organized with approximate subsumption relations...

We propose to integrate various pieces of information about a web page (search queries, social annotations, terms extracted from the pagetext) into a navigational menu. This menu displays an auxiliary set of tags (navigational tags) selected with the goal of helping user navigation. We propose a novel framework (navigational utility) for comparing different tag selection methods. We also invest...
