The principle of conventional magnetic recording is that magnetic fields are applied parallel to the plane of the magnetic medium. As described in this paper, the invention and development of a new method of placing the magnetized information perpendicular to the plane of the magnetic recording medium is presented. The yield in the mass production of high-density hard disk drives (HDDs) for per...

Recently ubiquitous cities have been developed all over the world. They aim at embedding information and communication technology, information services and digital content in the urban landscape to make the citizens’ everyday lives easier. One of these future-oriented cities is Oulu in Finland. It makes part of the most “intelligent” communities in the world. Oulu offers an information and comm...

Projects using geographic information tools involve a large variety of data objects, represented in different formats. Many efforts pursue standards to represent each kind of data object, and the interoperability between geographic information tools. The proliferation of data and tools raises the need for their reuse. This need can be extended to project reuse. This work presents a proposal to ...

In this paper we describe our use of information visualization to facilitate the analysis of in-the-wild video data. Video recording is often the method of choice when conducting inthe-wild studies. It results in highly rich and detailed data collections that can be revisited many times and analyzed from different perspectives. However, the qualitative analysis of video recordings collected in ...

Collaborative tagging has emerged as a common solution for labelling and organising online digital content. However, collaborative tagging systems typically suffer from a number of issues such as tag scarcity or ambiguous labelling. As a result, the organisation and browsing of tagged content is far from being optimal. In this work we present a general scheme for building a folksonomy-based tag...

The scope of this paper is to propose an innovative interactive system for 3D visualization of multimedia databases. In such databases, the digital content is accompanied by complementary information and metadata that describe the content. The proposed 3D visualization environment is able to provide multiscale representations driven by appropriate clustering processes that exploit content descr...

With the growing amount of people using the Internet, and creating digital content and information, knowledge retrieval becomes a critical task. Knowledge retrieval allows people to find content they search for when they need it. Ongoing efforts provide frameworks and standards for annotating digital and non-digital content semantically to describe resources more precisely and processable in co...

A panel discussion regarding digital archiving efforts by the U.S. Library of Congress (LC). In December 2000 Congress authorized LC to develop and execute a plan for a National Digital Information Infrastructure and Preservation Program (NDIIPP). LC developed a plan, in collaboration with other federal and nonfederal entities, to build a national network of organizations with responsibilities ...

The paper introduces the use of Semantic Web services within AquaRing, an EC-funded project concerning aquatic environments and their resources, and an ontology used to support educational contents annotation and retrieval. The aim of the project is to improve access to the vast amount of digital content concerning the aquatic environment and its resources, as well as to support enhanced educat...

During the last decade, several recommendation systems have been proposed that help people to tackle information overload of digital content by effectively presenting content adapted to user’s tastes and needs. However, these personalization technologies are far from perfect and much research is needed to improve the quality of recommendations and, particularly, user satisfaction. In this paper...
