introduction: the study on psychology of marriage rooted in the social issues. the field has also found its way to biomedicine. the current research, based on the document-term clustering methods, focus on term-proximity of documents that were related to the field of psychology of marriage in biomedicine literature. methods: the co-occurrence frequency of terms within the two different corpuses...
This paper presents the cartographic elements of a system for classifying and visualizing highdimensional geographic datasets. The system has been developed as part of the Land Ocean Interactions in the Coastal Zone [LOICZ] project. The goal of the system is to develop regional and global typologies of coastal zones using large multi-variable datasets. Our implementation brings together statist...
Chronic obstructive pulmonary disease (COPD) is defined independently of exacerbations, which are largely a feature of moderate-to-severe disease. This article is the result of a workshop that tried to define exacerbations of COPD for use in clinical, pharmacological and epidemiological studies. The conclusions represent the consensus of those present. This review describes definitions, ascerta...
Résumé. On présente deux méthodes de classification hiérarchique ascendante de variables quantitatives et de fréquences. Chaque noeud de ces hiérarchies regroupe deux classes de variables à partir d’une analyse factorielle particulière basée sur les variables représentatives de ces deux classes. Par cette méthode, on dispose, à chaque pas, d'un plan factoriel permettant de représenter à la fois...
Classification schemes, such as the DMoZ web directory, provide a convenient and intuitive way for humans to access classified contents. While being easy to be dealt with for humans, classification schemes remain hard to be reasoned about by automated software agents. Among other things, this hardness is conditioned by the ambiguous nature of the natural language used to describe classification...
The most famous, and simple suboptimal search algorithm is Weighted A∗ (WA∗) (Pohl 1970). Similar to A∗, WA∗ uses two data structures: OPEN and CLOSED. Initially, OPEN contains only the start state and CLOSED is empty. At every iteration, the algorithm chooses the state in OPEN that minimizes the cost function f(n) = g(n)+W ·h(n), where g(n) is the cost of the lowest cost path found so far, fro...
The value of the perinatal autopsy The perinatal autopsy can provide important information to the family, the clinician, and society [1–3]. When the parents give their consent for a post mortem examination on their baby, they are hoping to know why and how their baby died. It is quite reassuring to the parents to know that whatever has gone wrong, it did not happen because they did something wr...
BACKGROUND Rising cesarean section (CS) rates are a major public health concern and cause worldwide debates. To propose and implement effective measures to reduce or increase CS rates where necessary requires an appropriate classification. Despite several existing CS classifications, there has not yet been a systematic review of these. This study aimed to 1) identify the main CS classifications...
This paper discusses issues and solutions for supporting multiple overlapping classifications in database systems. These classifications are commonly found in science, although they are often ignored in computing applications for scientific data, and inappropriate solutions adopted as their replacement. Known database models and classification techniques offer some degree of support for multipl...
Several reverse engineering techniques classify software system components into subsystems. These techniques are designed to discover such classifications when the classifications are unknown. The techniques are tested and evaluated, however, by matching the classifications they recover against expected classifications. Several such techniques may be compared by experimentally evaluating their ...
