Aim: Accurate classification of diabetic foot ulcers is essential for inter-clinician communication, assessment of healing tendency, and determination of treatment options. Ulcer classification is performed by many different caregivers involved, but their agreement is unclear. The aim of this study was to assess the inter-observer agreement (IOA) of the most commonly used classification systems...

Systematized subject classification is essential for funding and assessing scientific projects. Conventionally, classification schemes are founded on the empirical knowledge of the group of experts; thus the expert’s perspectives have influenced the current systems of the scientific classification. Those systems archived current state-of-art in practice, yet acceleration of scientific turnover ...

We study the behaviour of nonnegative solutions of the reaction-diffusion equation    ut = (u)xx + a(x)up in R× (0, T ), u(x, 0) = u0(x) in R. The model contains a porous medium diffusion term with exponent m > 1, and a localized reaction a(x)up where p > 0 and a(x) ≥ 0 is a compactly supported function. We investigate the existence and behaviour of the solutions of this problem in dependenc...

Licences are a crucial aspect of the information publishing process in the web of (linked) data. Recent work on modeling of policies with semantic web languages (RDF, ODRL) gives the opportunity to formally describe licences and reason upon them. However, choosing the right licence is still challenging. Particularly, understanding the number of features permissions, prohibitions and obligations...

Facetag is a working prototype of a semantic collaborative tagging tool conceived for bookmarking information architecture resources. It aims to show how the widespread homogeneous and flat keywords' space of tags can be effectively mixed with a richer faceted classification scheme to improve the “information scent” and “berrypicking” capabilities of the system. The additional semantic structur...

Correspondence to Ellen Nordal; [email protected] Disease classification in rheumatology is a matter of debate, in paediatrics between International League Against Rheumatism (ILAR) classification ‘pros and cons’, as well as between paediatric and adult rheumatologists. Indeed, there is no consensus yet about how we should name the disease of adults with juvenile idiopathic arthritis ( JI...

We consider the problem of classifying documents not by topic, but by overall sentiment, e.g., determining whether a review is positive or negative. Using movie reviews as data, we find that standard machine learning techniques definitively outperform human-produced baselines. However, the three machine learning methods we employed (Naive Bayes, maximum entropy classification, and support vecto...

Up to unitary equivalence, there are a finite number of tight frames of n vectors for C which can be obtained as the orbit of a single vector under the unitary action of an abelian group G (for nonabelian groups there may be uncountably many). These so called harmonic frames (or geometrically uniform tight frames) have recently been used in applications including signal processing (where G is t...

This paper deals with design and implementation of Look-up processor which performs IPv4 and IPv6 packet classification on the basis of configurable rules. They can be specific e.g. for routing, filtering or attack detection so the target usage of the processor results from their selection. The origin intention is to use it in PC-based router which is being developed under the Liberouter projec...

(A) A Polish metric space is a complete separable metric space (X, d). Our first goal in this paper is to determine the exact complexity of the classification problem of Polish metric spaces up to isometry. Our work was motivated by a recent paper of Vershik [1998], where the author remarks (in the beginning of Section 2): “The classification of Polish spaces up to isometry is an enormous task....
