It is not obvious how to define quality metrics, on different kinds of metadata and collections, and many different perceptions may be valid. Nevertheless, a metadata quality metric will help the collection administrators detecting and improving the weaknesses of their metadata, and Europeana locating the most problematic collections, in terms of metadata quality, and prompt their administrators to improve their descriptions. We developed an adaptive quantitative metadata quality metric and a system to implement it for Europeana Local that takes into account the significance of the different metadata elements in the record, and also the values that they contain. In controlled values, their distribution is of importance, while for free text values the length of the description is used. We applied this metric to collections outside Europeana to find reasonably expected thresholds and weights for each individual value in the Europeana context and both outside and inside Europeana, and compared the results, to get a general quantitative and qualitative feeling of the diversity in the record descriptions, to produce the appropriate advice for the collection administrators and make quality observations.","PeriodicalId":91811,"journal":{"name":"The ...

Iris data are expensive and difficult to be acquired and their amount plays an important role in recognition accuracy when data mining methods are used. However, privacy issues often restrict open exchange of data between stakeholders. The present article presents a privacy-preserving neural network protocol, for horizontally-partitioned datasets, i.e. datasets that share common attributes but contain different records at each party. The proposed protocol assumes a malicious user model and does not use homomorphic cryptographic methods which are inherently only suited for a semi-trusted user environment. The performance analysis shows that the communication overhead is low enough to warrant its use while the computational complexity is identical in most cases with the centralized computation scenario (e.g. a trusted third party). The accuracy of the output model is only marginally subpar to a centralized computation on the union of all datasets. Another important aim of this work is to search proper choice of the part of the iris signature for person identification and calculating torsional eye movements. Also, estimate changes of the iris contour, sections of the iris and elements of the iris signature. The mathematical model of formation of the iris image on the plane was compared with the real image of the iris.","PeriodicalId":91811,"journal":{"name":"The ...

Therefore, 50 participants aged between 60 and 90 years (average age 71.26 years) were surveyed within the context of a requirement analysis, about the perceived positives and negatives of using technological support in everyday life. The analysis was based on data collected in semi-structured, face-to-face interviews from February to March 2011. The study revealed that men had distinctly higher levels of trust in sensor technology than women (7.64 vs. 6.83). The most interesting target audience for AAL technology, older people who are living in a single household, showed lower trust values in sensors than people living together with another person (6.41 vs. 7.83). Another result, important for developing AAL technology, was that fixed attachment of sensors in the accommodation was considered more reliable (7.80) than attachment to clothing or on/in the body. Regarding which characteristics formed the basis for trust in technology; reliability (9.72) and ease of use (9.52) were assessed as highly important. Visibility (8.45) and brand name (5.02) were seen as less important, whereas high costs (3.90) only slightly influenced reliance in AAL technology. Based on these results, further research regarding different stratification criteria, such as gender and housing situation, is needed. In order to gain a holistic model of elderly persons' trust in AAL further surveys, including this target audience, must be performed.","PeriodicalId":91811,"journal":{"name":"The ...

The next step in the completion of this vision is to make major breakthroughs in artificial intelligence. In fact, it is the key component for allowing sensors and effectors to give useful services when it is appropriate. In consequence, researchers need to conduct more experiments in realistic setting (e.g. smart home). In order to face this challenge, many research teams try to build new experimental infrastructures without any background experience, guidance or even a real idea of their research needs and issues. Our team is composed of specialists in AI for cognitive assistance and has worked with four major smart home infrastructures. From that experience, we propose, in this paper, a set of guidelines for designing and implementing an efficient smart home architecture on both hardware and software perspective. This paper aims to be a major step toward the AI development (rapid prototyping) and smart home research. Moreover, we share our recent experience with the construction of a new smart home and clinical trials conducted at our laboratory with real Alzheimer's subjects.","PeriodicalId":91811,"journal":{"name":"The ...
