Modular Ontology

Ontologies are widely used nowadays. However, the plethora of ontologies currently available online, makes it really difficult to identify which ontologies are appropriate for a given task and to decide on their quality characteristics. This is further complicated by the fact that multiple quality criteria have been proposed for ontologies, making it even more difficult to decide which ontology to adopt. In this context, in this paper we present Delta, a modular online tool for analyzing and evaluating ontologies. The interested user can upload an ontology to the tool, which then automatically analyzes it and graphically visualizes numerous statistics, metrics, and pitfalls. Those visuals presented include a diverse set of quality dimensions, further guiding users to understand the benefits and the drawbacks of each individual ontology and how to properly develop and extend it.

Product-related information can be integrated with the help of a product ontology, which can provide consensual definitions of concepts and inter-relationships relevant in a product domain of interest. A product ontology is either given by a third party or results from ontology engineering. In both cases, the problem is how to assess its quality, and then select the “right” ontology. This chapter: (1) proposes a metrics suite for product ontology evaluation based on semiotic theory, and (2) demonstrates the feasibility and usefulness of the metrics suite using a supply chain model. The contribution of this research is the comprehensive metrics suite that takes into account the various quality dimensions of product ontology.

Ontology or domain specific vocabulary is indispensable to a semantic web-based application; therefore, its evaluation assumes critical importance for maintaining the quality. A modular ontology is intuitively preferred to as a monolithic ontology. A good quality modular ontology, in turn, promotes reusability. This chapter is directed at summarizing the efforts towards ontology evaluation, besides defining the process of evaluation, various approaches to evaluation and underlying motivation. In particular, a modular ontology's cohesion and coupling metrics have been discussed in detail as a case study. The authors believe that the body of knowledge in this chapter will serve as a beginning point for ontology quality engineers and at the same time acquaint them with the state-of-art in this field.

Integration Problems

In recent years, product ontology has been proposed for solving integration problems in product-related information systems such as e-commerce and supply chain management applications. A product ontology provides consensual definitions of concepts and inter-relationships being relevant in a product domain of interest. Adopting such an ontology requires means for assessing their suitability and selecting the “right” product ontology. In this article, the authors (1) propose a metrics suite for product ontology evaluation based on semiotic theory, and (2) demonstrate the feasibility and usefulness of the metrics suite using a supply chain model. The contribution of our research is the comprehensive metrics suite that takes into account the various quality dimensions of product ontology.

Lentils rejected for use as human food were evaluated as an alternative to soybean meal (SBM) in barley-based diets containing 16% crude protein (CP). The first study involved 64 male castrates (four pigs/pen) fed diets containing 0, 5, 10 and 20% Laird lentils (LL, 23 % CP) ad libitum from 25 to 97 kg liveweight in a randomized block design with four replicates. Growth rates (mean of 914 g d−1) were similar on all diets but pigs fed the 10% LL diet were the most efficient (366 vs. 354 g gain kg−1 diet, P < 0.05), had thinner backfat (15.7 vs. 17.7 mm at 90 kg liveweight, P < 0.05) and more acceptable (P < 0.05) meat quality by physical and sensory evaluation compared to control (0% LL) pigs. The subsequent study, a one-way factorial design with four replicates using 60 gilts (3/pen) and five diets containing 0, 10, 20, 30 and 40% Eston lentils (EL, 27% CP), was similarly conducted over the period from 25 to 90 kg liveweight. As observed previously, dietary lentils promoted curvilinear responses (usually optimum at 20% EL) although there were few significant (P < 0.05) differences between lentil-fed and control pigs apart from their meat quality criteria. Taking into account the costs of barley and SBM replaced, the value of cull lentils in each study was maximum at the 10% inclusion rate. Key words: Pig, growth, carcass, meat quality, lentils

Abstract Measuring the quality of a b-learning environment is critical to determine the success of a blearning course. Several initiatives have been recently conducted on benchmarking and quality in e-learning. Despite these efforts in defining and examining quality issues concerning online courses, a defining instrument to evaluate quality is one of the key challenges for blended learning, since it incorporates both traditional and online instruction methods. For this paper, six frameworks for quality assessment of technological enhanced learning were examined and compared regarding similarities and differences. These frameworks aim at the same global objective: the quality of e-learning environment/products. They present different perspectives but also many common issues. Some of them are more specific and related to the course and others are more global and related to institutional aspects. In this work we collected and arrange all the quality criteria identified in order to get a more complete framework and determine if it fits our b-learning environment. We also included elements related to our own b-learning research and experience, acquired during more than 10 years of experience. As a result we have create a new quality reference with a set of dimensions and criteria that should be taken into account when you are analyzing, designing, developing, implementing and evaluating a b-learning environment. Besides these perspectives on what to do when you are developing a b-learning environment we have also included pedagogical issues in order to give directions on how to do it to reach the success of the learning. The information, concepts and procedures here presented give support to teachers and instructors, which intend to validate the quality of their blended learning courses.

BACKGROUND With the public coverage of smartphones now at a global level, a major growth in the use of apps related to the health category, specifically those concerned with foot health can be observed. Although new, these apps are being used practically for scanning feet with an aim to providing accurate information about various properties of the human foot. With the availability of many ‘foot scanning and measuring apps’ in the commercial market (app stores), the need for an evaluation system for such apps can be deemed necessary as little information regarding the evidence-based quality of these apps is available. OBJECTIVE To characterize the assessment of measurement techniques and essential software quality characteristics of mobile foot measuring apps, and determine their effectiveness for potential use as commercial professional tools for foot care health professionals such as pedorthists, podiatrists, orthotists and so on, to assist in measuring foot for custom shoes, and for individuals to enhance the awareness of foot health and hygiene and prevention of foot-related problems. METHODS An electronic search across Android and iOS app stores was conducted between July 2020 and August 2020 for apps related to foot measurement. Mobile apps with stated goals of foot measurement and general foot health were identified and selected by three independent raters and discrepancies regarding the selected apps were resolved via a fourth rater. A modified rating tool based on previous works of app rating tools was adopted and extended for rating of selected apps. The internal consistency of the rating tool was tested with a group of 6 people who rated the selected app over an interval of 5-6 days. This modified scale was then used to produce evaluation scores for the selected range of foot measurement apps and the inter-rater reliability of this study was also calculated. Discrepancies found for any criteria during app reviews were discussed mutually by the raters to arrive at a unified decision. RESULTS Evaluation inferences found all apps failing to meet even half of the measurement-specific criteria required for the proper manufacturing of custom-made footwear. 23% (6/26) of apps were found to utilize either external scanners or advanced algorithms to reconstruct 3D models of user foot that can possibly be used for ordering custom-made footwear (shoes, insoles/orthoses) and medical casts for fitting irregular foot sizes and shapes. Apps had varying levels of performance and usability, with the overall measurement functionality being subpar with mean 1.97 out of 5. Apps that were linked to online shops and stores (shoe recommending) were assessed to be more usable than other foot measuring apps, but didn’t work with custom shoe sizes and shapes. Overall, current apps for foot measurement do not follow any specific guidelines for measurement purposes. CONCLUSIONS Majority of the commercial apps in app stores cannot be comprehensively evaluated as viable apps ready for use as professional tools in assisting foot care health professionals or individuals in measuring their foot for custom-made footwear purposes. Apps lack software quality characteristics that are needed for proper measurement and for providing awareness about foot health and induce motivation to prevent and cure foot-related problems. Guidelines similar to the essential criteria items in this study are needed to be developed for future apps aimed at foot measurement for custom-made or individually fitted footwear and creating awareness about foot health.

Purpose – The purpose of this paper is to identify service quality dimensions that could enhance the level of services provided by a variety of carriers and rank them, accordingly. Design/methodology/approach – This research aims to identify service quality dimensions that could enhance the level of services provided by a variety of carriers and rank them, accordingly. Findings – The results show that “safety,” “timeliness,” and “variety and type of airplane” are the most important service quality criteria from the passengers’ viewpoint. It also indicates that the most and least important dimensions of service quality are “tangibles” and “responsiveness,” respectively. The results ranked the airlines from one to three as Emirates Airline, Mahan Air, and Iran Air. Originality/value – Most of the service quality criteria are descriptive and are stated using lingual expressions (cardinal or ordinal scales). Therefore, evaluation of perceptions and expectations of customers regarding service quality using non-fuzzy methods ignores the ambiguity involved in individual judgments.
