The popularity of augmented reality (AR) applications on mobile devices is increasing, but there is as yet little research on use in real settings. We review data from two pioneering field trials where MapLens, a magic lens that augments paper-based city maps, was used in small-group collaborative tasks. The first study compared MapLens to a digital version akin to Google Maps, the second looke...

Scholars writing books that are widely used to support teaching in higher education may be undervalued due to a lack of evidence of teaching value. Whilst sales data may give credible evidence for textbooks, it may poorly reflect educational uses of other types of books. As an alternative, this article proposes a method to automatically search for mentions of books in online academic course syl...

Automatic acquisition of inference rules for predicates has been commonly addressed by computing distributional similarity between vectors of argument words, operating at the word space level. A recent line of work, which addresses context sensitivity of rules, represented contexts in a latent topic space and computed similarity over topic vectors. We propose a novel two-level model, which comp...

This paper describes TM/XML, an XML syntax for Topic Maps that is very close to the natural, or colloquial, XML representation of the information in the topic map. It can be used to process Topic Maps data with XML tools, and integrate non-Topic Maps systems with Topic

Despite the increasing availability of various forms of digital maps and guides, paper still prevails as the main information medium used by tourists during city visits. The authors describe how recent technologies for digitally augmented paper maps can be used to develop interactive paper maps that provide value-added services for tourists through digital overlays. An initial investigation int...

a comprehensive digital, high quality production. A good overview of the developments of the Systems and applica¬ tions of this time is given in the Conference volume of the Cartography Congress 1996 in Interlaken (Hurni 1996). Relatively early it was asked whether the new technologies and media could maintain the quality of the maps and even improve on them, and if required, whether totally ne...

Performing financial benchmarks in today’s information-rich society can be a daunting task. With the evolution of the Internet, access to massive amounts of financial data, typically in the form of financial statements, is widespread. Managers and stakeholders are in need of a tool allowing them to quickly and accurately analyze this data. An emerging technique that may be suited for this appli...

the purpose of this paper is to obtain necessary and suffcient conditionsfor existence approximate fi xed point on geraghty-contraction. in this paper,de nitions of approximate -pair fi xed point for two maps tα , sα and theirdiameters are given in a metric space.

A teacher must consider many details when planning and organizing a course. This paper shows how the new Topic Map computer technology can help in this process. The developed Topic Map for the CS knowledge domain is used for the analysis of introductory CS courses, but it can be also applied to other courses, including in noncomputer disciplines. Well-structured Topic Maps may become a solid ba...
