Optische draadloze verbinding van 10 Gbit/sec

Aircision en TNO hebben eind mei een optische draadloze verbinding van 10 Gbit/sec over 2,5 km gerealiseerd. Het is een eerste veldtest voor wat uiteindelijk moet leiden tot een manier om afgelegen gebieden van een snelle internetverbinding te voorzien. Onderzoeksinstituut TNO is gespecialiseerd in FSO, Free Space Optics, voor communicatie met...

Intelligent Disease Self-Management with Mobile Technology

Cost-effective mobile healthcare must consider not only technological performance but also the division of responsibilities between the patient and care provider, the context of the patient’s condition, and ways to implement patient decision support and tailored interaction.

Supporting active patient self-care

We are currently confronted with a trend of increased pressure on health care, with associated increasing financial costs, due to an aging society and the expected increase in the prevalence of disability and chronic disease. Finding measures for cost reduction, without sacrificing quality of care, is a significant healthcare challenge....

Reliability and Validity of Query Intent Assessments

In most intent recognition studies, annotations of query intent are created post hoc by external assessors who are not the searchers themselves. It is important for the field to get a better understanding of the quality of this process as an approximation for determining the searcher's actual intent. Some studies have investigated the...

A multi-dimensional model for search intent.

The interaction of users with search engines is part of goal driven behaviour involving an underlying information need. Information needs range from simple lookups to complex long-term desk studies. This paper proposes a new multi-dimensional model for search intent, which can be used for the description of search sessions. Using examples from...

When is a query a question? Reconstructing wh-requests from ad hoc-queries

How does the Library Searcher Behave? A Contrastive Study of Library Search against Ad-hoc Search.

Annotation of URLs: More than the sum of parts

Recently a number of studies have demonstrated that search engine logfiles are an important resource to determine the relevance relation between URLs and query terms. We hypothesized that the queries associated with a URL could also be presented as useful URL metadata in a search engine result list, e.g. for helping to determine the semantic...

Annotating URLs with query terms: What factors predict reliable annotations?

A number of recent studies have investigated the relation be-ween URLs and associated query terms from search engine log files. In [5], the query terms associated with the domain of a URL were used as features for a URL classification task. The idea is that query terms that lead to successful classification of a URL are reliable semantic...
