Topic: Emerging Ontology Showcase (session-2)
Abstract by KenBaclawski / MikeBennett


 * The number of publicly available ontologies is growing rapidly, with search engines reporting over 10,000 already. This is the beginning of a mini-series intended to provide a venue for the developers of major new ontologies to present their work products to the ontology community. Each session will showcase 2 or 3 important ontologies that were recently released or updated.


 * Refer also to details at the project homepage for this mini-series at: EmergingOntologyShowcase

Titles and Abstracts
Ontologists and Domain Experts focusing on Chronic Wounds : Different Worlds on the Same Planet? - SvenVanPoucke


 * http://ontolog.cim3.net/file/work/EmergingOntology/EmergingOntology_20081016/SVP-bw_20081016.jpg [Sven Van Poucke, MD]


 * Abstract: This session will present the painstaking process of a clinical and scientific community in their effort to quantify the healing of chronic wounds by the deployment of a platform for semantic knowledge extraction.


 * The Woundontology Consortium is a semi-open, international, virtual community of practice devoted to advancing the field of research in non-invasive wound assessment by image analysis, ontology and semantic interpretation and knowledge extraction (content-based visual information retrieval).


 * Professionals dealing with wound patients make clinical decisions principally, but not solely based on their visual perception. The descriptive analysis of wounds however is poorly standardized and rarely reproducible.


 * There is a consensus within the wound care community that a systemic approach to the patient's assessment is necessary to treat a chronic wound ("Look at the whole patient, not just the hole in the patient."). Therefore, digital imaging of wounds constitutes only a small piece of the assessment process. During the assessment of wounds, the experience of the clinician plays a significant role in identifying the actual state of a wound. The assessment is carried out visually and qualitatively based on

his-her subjective experience. Therefore, this procedure suffers from potential interpretational variability, lack of comparative analysis, and it is time consuming.


 * It is quite interesting to observe that in a era of considerable pressure on economical resources for health care, systems such as the red-yellow-black wound classification system of the wound bed color, their possible relation with a wound healing phase and their possible underlying organic meaning (the nonuniform mixture of black necrotic eschar, yellow necrosis and fibrin (slough), and red granulation tissue, ...), continue to be the cornerstone of clinical guidelines and protocols, and are published

by international societies and key opinion leaders without any semantic, ontologic or colorimetric formal description, definition or consensus of the used terminology.

The GoodRelations Ontology: Making Semantic Web-based E-Commerce a Reality - MartinHepp


 * http://ontolog.cim3.net/file/work/EmergingOntology/EmergingOntology_20081016/martinhepp-bw_20081016.jpg [Professor Martin Hepp]


 * Abstract: A promising application domain for Semantic Web technology is the annotation of products and services offerings on the Web so that consumers and enterprises can search for suitable suppliers using products and services ontologies. While there has been substantial progress in developing ontologies for types of products and services, namely eClassOWL, this alone does not provide the representational means required for e-commerce on the Semantic Web. Particularly missing is an ontology that allows describing the relationships between (1) Web resources, (2) offerings made by means of those Web resources, (3) legal entities, (4) prices, (5) terms and conditions, and (6) the aforementioned ontologies for products and services.


 * In the talk, I will explain the need and potential of the GoodRelations ontology, introduce its key conceptual elements, highlight several lessons learned, and summarize design decisions with respect to to modeling approaches and the appropriate language fragment, which may be relevant for other ontology projects, too.

Questions and Discussion captured from the chat session:
RaviSharma: Dr. Poucke - is there a color standardization as illumination as well as reflection / scattering properties require goniometric standardization for comparison?

RaviSharma: Dr. Poucke - if in the clinics and hospital environment we could first standardize the pallet such as color, hue, grayscale etc then comparison with healing or another wound would be more semantically meaningful. This pallet could be presented electronically rather than through a small color sclae with only a few solid colors as shown in slide 11 & 14

RaviSharma: Dr. Poucke - the illumination source can have a spectral spread and similarly the receiving camera sensors spectral response. This is the first consideration and image processing tools are available from remote sensing and image analysis that can help in standardization of color, color variation, scan through wound and pattern matching but other in-vivo or pathologies and clinical measurements are to be grouped together as integrated datasets so as to be able to compare and or see progress of healing rates?

Yves Vander Haeghen: Ravi, have a look at http://www.c4real.biz for a little more theory on the color calibration technology

RaviSharma: Thanks for the link Yes I will look ...

RexBrooks: I am wondering if you (or anyone) knows of any work being done to apply similar techniques to symptomology, e.g. remote diagnosis from combination of visual and verbal information for use in emergencies?

SvenVanPoucke: Rex, of course ontology is developed for clinical practice, the problem is that clinicians are still too far from ontology theory ... nice to discuss by email

RexBrooks: I'd like to do that.

RaviSharma: Prof. Hepp - Is your example of good relations e-commerce to be understood by us as Ontology as a Service that helps standardize the meaning of commercial services through reasoners and other engines and uses at the backend the knowledge and databases. But like the ebXML example, there also has to be a standardization of the ecommerce terms very similar to autofill options in browsers for exchanging the identity and profile.

RaviSharma: Prof. Hepp - are we saying that ontology and namespace and associated taxonomies and standards in business process are exemplied by your use cases today?

RaviSharma: Prof. Hepp - there is no doubt in the value of your approach. Our next steps for such successful implementation would be the acceptance by user communities such as those were adopted by e-exchanges communities and verticals. Direct materials worth billions of dollars in semiconductor, automotive and metal or petro exchanges are taking place and we need communities such as amazon, etc. to accept such technologies and solutions, great presentation.
