Expertentreffen Obstruktive Atemwegserkrankungen: Targets und Methoden

New insights into the pathogenesis and clinical course of chronic obstructive pulmonary disease (COPD) and asthma have become available. Systematic analyses of well-defined and intensively monitored patient cohorts are being published, particularly from the ECLIPSE cohort in the U.S.A. and from the network COSYCONet in Germany. Important articles from 2011 on COPD and asthma put former concepts into question. There is a new understanding of the relationship between parenchymal destruction and bronchial obstruction in COPD as well as on the impact of cardiovascular comorbidity. Computed tomography allows high-resolution imaging of lung structures, and MRI delivers supplementary functional information. Researchers have also investigated the value of patient-reported outcomes, such as quality of life, dyspnoea, or the COPD assessment test (CAT). Members of the GOLD committee are trying to establish a feasible classification of the multiple facets of COPD. With respect to treatment, novel data on beta-adrenergic antagonists in COPD and on muscarinic antagonists in asthma have been published. These aspects were discussed during an expert meeting and are now summarised in the present review article.

Information Object Identification System Modeling and Visual Coding Rule Design

Based on the description of an information object identification system and aggregate analysis of linear & faceted classification methods, an identification hierarchical construction method and a collection object enumeration method are put forward to model the information object identification system. Its system architecture is constructed and identifying nodes and managing nodes are used to define and associate information objects. According to coding theories, the information identification system is mapped into a visual coding rule system on the condition that the information object architecture, code collection and serialization, and coding constraints are retained. According to a dynamic coding rule tree, rule templates, and code generation methods, the corresponding visual interface is developed. Finally, the XML format is used to design a powerful, extensible and flexible data structure to realize the visual coding rule system.

Research on Component Retrieval Methods

With the development of the component technology and the expansion of component library, representing and retrieving components, the two core technologies of component library management have been a focus on research hot issues in researches. Based on the present widely-used component faceted classification description method and its features, and from the different requirements and ways of component retrieval that were used by component re-users, three component retrieval ways based on browser, facet and term, the five corresponding matching models and two matching algorithms are proposed. The theoretical analysis and experimental results show that the three kinds of retrieval methods used in large-scale component library component retrieval, will meet the component reuse of various searching requirements and that these ways are feasible in retrieval efficiency..

UDC on the Internet: Theory and project in evolution for use of indexing and retrieval systems

The starting point of this article is to compare the features of faceted classification and ontologies with a re-evaluation of UDC (Universal Decimal Classification) as an analytico-synthetic classification system. We are therefore proposing a theory that was used as the basis of a project in the 1980s but which will imply an advance in the field of information retrieval in the future context of the Internet. This theory is based on the post-coordinated use of LCSH (Library of Congress Subject Headings) and the setting-up of their equivalence with UDC for indexing. The retrieval process is based on the generation of clusters characteristic of data mining and the linking of existing controlled vocabularies and free language in all languages with the corresponding UDC notations. This will be achieved by making UDC compatible with existing classifications, thus profiting from all the knowledge structured so far, thanks to the creation of a suitable format.

ENT: A Generic Meta-Model for the Description of Component-Based Applications

Current best practice in modeling component-based applications is the use of UML extended by a profile. This solution provides a general and common approach of application description and allows to capture some details based on the concrete component model. It has however disadvantages due to the limitations of UML itself, like little scalability or lack of inherent model semantics. In this paper we propose a solution to overcome these limitations, in the form of a meta-model developed directly for the description of components and component-based applications. Its unique aspect is the use of faceted classification to introduce additional semantics and structuring to the derived models. We describe the features and advantages of this meta-model and illustrate its aspects on a model example of a simple OSGi application. At the end of paper we also propose the usage of this meta-model in visualization of component-based applications.

Anticipating new media: A faceted classification of material types

The emergence of new media types, many seemingly without counterparts in the non-digital world, challenges the readiness of existing knowledge organization schemes to accommodate them. A knowledge organization scheme based on a faceted analysis of existing classes of bibliographic materials is likely to accommodate new developments better than one based on a list of unanalyzed material types. The faceted analysis undertaken here, in which seven facets are recognized (content, generation of content, recording of content, publication/distribution, physical characteristics, perception/use, and relationships) shows the inadequacy of the traditional view of the bibliographic community of a fundamental distinction between content and carrier; interaction between content and carrier is common and enters into the characterization of material types. The facet analysis is validated by applying it to two new material types, wikis and blogs.

Ranganathan's layers of classification theory and the FASDA model of classification

Describes four waves of Ranganathan’s dynamic theory of classification. Outlines components that distinguish each wave, and porposes ways in which this understanding can inform systems design in the contemporary environment, particularly with regard to interoperability and scheme versioning. Ends with an appeal to better understanding the relationship between structure and semantics in faceted classification schemes and similar indexing languages.

Reporting Observational Studies of the Use of Information Technology in the Clinical Consultation

To develop a classification system to improve the reporting of observational studies of the use of information technology (IT) in clinical consultations. Literature review, workshops, and development of a position statement. We grouped the important aspects for consistent reporting into a "faceted classification"; the components relevant to a particular study to be used independently. The eight facets of our classification are: (1) Theoretical and methodological approach: e.g. dramaturgical, cognitive; (2) DATA COLLECTION: Type and method of observation; (3) Room layout and environment: How this affects interaction between clinician, patient and computer. (4) Initiation and Interaction: Who starts the consultation, and how the participants interact; (5) Information and knowledge utilisation: What sources of information or decision support are used or provided; (6) Timing and type of consultation variables: Standard descriptors that can be used to allow comparison of duration and description of continuous activities (e.g. speech, eye contact) and episodic ones, such as prescribing; (7) Post-consultation impact measures: Satisfaction surveys and health economic assessment based on the perceived quality of the clinician-patient interaction; and (8) Data capture, storage, and export formats: How to archive and curate data to facilitate further analysis. Adoption of this classification should make it easier to interpret research findings and facilitate the synthesis of evidence across studies. Those engaged in IT-consultation research shouldconsider adopting this reporting guide.

P-MART: Towards a classification of online prediction markets

Prediction Markets are a family of Internet–based social computing applications, which use market price to aggregate and reveal information and opinion from dispersed audiences. The considerable complexity of these markets inhibited the full realization of the promise so far. This paper offers the P–MART classification as a tool for organizing the current state of knowledge, aiding the construction of tailored markets, identifying ingredients for Prediction Markets’ success and encouraging research. P–MART is a dual–facet classification of implementations of Prediction Markets describing traders and markets. The proposed classification framework was calibrated by examining a variety of real–world online implementations. A publicly accessible wiki resource accompanies this paper in order to stimulate further research and future expansion of the classification.

A seleção conceitual na organização de domínios de conhecimento nas ciências humanas e sociais: o caso da cultura

Aborda o aspecto da seleção conceitual na organização de domínios de conhecimento nas ciências humanas e sociais, tomando como foco o conceito de cultura e sua complexidade peculiar. A seleção conceitual é uma etapa inicial da construção de sistemas de organização de conhecimento e mostra-se importante para um resultado final de qualidade, quanto à recuperação da informação. Para evidenciar a complexidade do domínio cultura, são analisadas as origens etimológicas das palavras amazônicas, onde se revelou uma grande diversidade cultural em línguas não-nativas originárias de continentes africano, europeu e asiático. Foi sugerido, como fundamento teórico-metodológico, para lidar com domínios complexos dessa natureza, a Teoria da Classificação Facetada, de Ranganathan e a Teoria dos Níveis Integrativos, do Classification Research Group.

Idea Collider: From a theory of knowledge organization to a theory of knowledge interaction

AbstractEditor's SummaryA new and novel addition to core concepts of information science and technology is the Idea Collider, adapting the conceptual basis of the particle accelerator. The Idea Collider is presented as a theory of information and an information retrieval tool that deconstructs text to the underlying elements – the concepts, ideas, knowledge entities, taxons and knowledge bases – and then reconstitutes groupings of data. The authors champion the idea of a “multiverse of knowledge,” in contrast to the “universe of knowledge” that is an important metaphor in traditional classification theory. A historical review of outstanding theoretical landmarks in classification theory explores the universe of knowledge metaphor, faceted classification theory and the universe of concepts, moving from a holistic view of existing knowledge to an elemental deconstruction that can account for all knowledge, past and future. The Idea Collider is proposed as a theoretical approach to identifying the essential parts of knowledge, dissociating those elements from culture‐ and time‐bound dimensions and making them available for a bottom‐up reassembly process.

Classifying art with Bliss

The second edition of the Bliss Classification (BC2) is a faceted classification scheme which reworks the original Bliss Classification, devised a century ago. It compares favourably in terms of its wealth of detail, the fineness of its analysis, its flexibility and the conciseness of its notation with its main rivals, the Library of Congress Classification, the Dewey Decimal Classification and the Universal Decimal Classification. The Art class, W, is one of the most detailed and best organised of the BC2 schedules, with the caveat that the author did not find the giving of priority to place over period and the listing of individual artists separately from their periods and places to be the most helpful arrangement. However, room is left for alternative arrangements within the scheme.

Using linked data to classify web documents

PurposeThe purpose of this paper is to find a relationship between traditional faceted classification schemes and semantic web document annotators, particularly in the linked data environment.Design/methodology/approachA consideration of the conceptual ideas behind faceted classification and linked data architecture is made. Analysis of selected web documents is performed using Calais' Semantic Proxy to support the considerations.FindingsTechnical language aside, the principles of both approaches are very similar. Modern classification techniques have the potential to automatically generate metadata to drive more precise information recall by including a semantic layer.Originality/valueLinked data have not been explicitly considered in this context before in the published literature.

To_be_classified: A Facet Analysis of a Folksonomy

This paper examines the use of the postulational approach to facet analysis to manually induce a faceted classification ontology from a folksonomy. An in-depth study of faceted classification theory is used to form a methodology based on the postulational approach, which is then used to facet analyze a dataset consisting of over 107,000 instances of 1,275 unique tags representing 76 popular non-fiction history books collected from the LibraryThing folksonomy

Classification, Facets, and Metaproperties

The paper argues that second order properties or metaproperties are essential for classification and navigation of information, for example for faceted classification and the navigation it generates. The paper observes that metaproperties, are not accommodated well within such standard schemes as Z3.1, description logics (DLs), and the formal ontologies OWL, BFO, and DOLCE
