Ontology selection: ontology evaluation on the real Semantic Web

The increasing number of ontologies on the Web and the appearance of large scale ontology repositories has brought the topic of ontology selection in the focus of the semantic web research agenda. Our view is that ontology evaluation is core to ontology selection and that, because ontology selection is performed in an open Web environment, it brings new challenges to ontology evaluation. Unfortunately, current research regards ontology selection and evaluation as two separate topics. Our goal in this paper is to explore how these two tasks relate. In particular, we are interested to get a better understanding of the ontology selection task and filter out the challenges that it brings to ontology evaluation. We discuss requirements posed by the open Web environment on ontology selection, we overview existing work on selection and point out future directions. Our major conclusion is that, even if selection methods still need further development, they have already brought novel approaches to ontology evaluatio

Consistency and Inconsistency in Celebrity Endorsements

The purpose of this study was to evaluate consumer attitudes towards brands when exposed to celebrity endorsements in cases where the personality of the celebrity does not match the personality of the brand (inconsistent). Theories used in this research included: Cognitive Dissonance Theory, how consumers are expected to react when receiving information that presents inconsistency; and Schema Theory, how information is stored in the form of schemas. A measure consisting of attractiveness, credibility, purchase intention and likeability was created based on studies by Spear and Singh (2004) and Halonen-Knight and Hurmerinta (2010) in order to evaluate consumer attitudes. A survey was given to 200 respondents to evaluate their attitude toward ten advertisements with celebrity endorsements. Five of the ads were consistent between celebrity and personality of the brand and five were inconsistent. Results showed that people had a significantly more positive attitude toward consistent ads compared to inconsistent ads

Clickbait as a Potential Threat in the Development of Cybercrime in Indonesia

This research examines the advancement and extensive diffusion of online news in Indonesia which contains discrepancies between the titles displayed and the content displayed (clickbait), where the content has the potential to contain backlinks that can carry a cybercrime. The purpose of this research is to assess the potential of clickbait in threatening the development of cybercrime in Indonesia, as well as to investigate the best legal regulations for eradicating clickbait in Indonesia. This research uses the normative legal research method followed by the interview method. The outcomes of this research point to the shift in news media from conventional to online making the target of online news journalists not only limited to reporting factual information but also pursuing a target audience of readers by using a clickbait title. The content of clickbait news that clearly does not match the title can deceive Indonesians, especially if accompanied by backlinks that actually spread many forms of cybercrime. In addition, it was found that there are no regulations in Indonesia that prohibit the dissemination of online news with clickbait, be it in the Press Law, ITE Law, Journalistic Code of Ethics, Cyber Media Reporting Guidelines, and the Criminal Code, which can be overcome by revising the ITE Law by adding related prohibitions in Article 28

Abstract: This study analyses 545 sample fanfiction stories (fics) in their stylistic feature variation by popularity and across eleven ‘fandoms’ in creative writing forums. Lexical richness, average sentence and paragraph lengths are isolated as promising measures for a text classifier to use in predicting a fic’s likely popularity in its fandom. Résumé: Cette étude analyse un échantillon de 545 chapitres d‘œuvres de fanfiction (fics) selon leur variation stylistique et leur popularité dans onze ‘fandoms’ différents. La richesse lexicale, longueur moyenne de phrase et longueur moyenne de paragraphe ont été choisis comme traits stylistiques propres à différencier les fics populaires des fics impopulaires

Using TREC for cross-comparison between classic IR and ontology-based search models at a Web scale

The construction of standard datasets and benchmarks to evaluate ontology-based search approaches and to compare then against baseline IR models is a major open problem in the semantic technologies community. In this paper we propose a novel evaluation benchmark for ontology-based IR models based on an adaptation of the well-known Cranfield paradigm (Cleverdon, 1967) traditionally used by the IR community. The proposed benchmark comprises: 1) a text document collection, 2) a set of queries and their corresponding document relevance judgments and 3) a set of ontologies and Knowledge Bases covering the query topics. The document collection and the set of queries and judgments are taken from one of the most widely used datasets in the IR community, the TREC Web track. As a use case example we apply the proposed benchmark to compare a real ontology-based search model (Fernandez, et al., 2008) against the best IR systems of TREC 9 and TREC 2001 competitions. A deep analysis of the strengths and weaknesses of this benchmark and a discussion of how it can be used to evaluate other ontology-based search systems is also included at the end of the paper

Special Olympics Fitness Assessment Project

Fitness is an important aspect of the Special Olympics mission. Physical activity, adequate nutrition, and hydration enhance athletes’ sports performance and improve health and overall quality of life. PURPOSE: The purpose of the study is under a service contract, assist Special Olympics International in data collection to evaluate the effectiveness of their Fit 5 program intervention. Analyze the health and fitness status of the Rio Grande Valley Special Olympics Athletes and the effectiveness of the Fit 5 program in the area. METHODS: Participant eligibility were current special Olympic athletes aged 18 and older in the Rio Grande Valley area. Forty-six special Olympic athletes (Mean±SD; 25.5±7yrs; 33±9kg/m2; 20 male) participated in the study; they completed a six-week exercise intervention consisting of 2 exercise sessions per week delivered remotely. The exercise sessions followed the Fit5 guidelines for endurance, strength, flexibility, and balance exercise recommendations. Three different measurements and surveys were taken: at the beginning of the implementation, after the six-week exercise intervention, and a month after. Special Olympics approved all surveys and exercises. Data were considered for statistical analysis if the participants completed the three measurements and surveys. Data collected included demographic information, healthy habits survey, resting heart rate, blood pressure, BMI, waist circumference, pushup and curl up endurance test, recovery heart rate for a step test, and a single leg balance test. One Way ANOVA was performed to compare the measurement in the three-time instances. RESULTS: Nine participants (25.77±5.8yrs; 36.9±7.8kg/mg2;3 male) completed the three sessions. There were small improvements in waist circumference and blood pressure, but One Way ANOVA showed no significant difference by the exercise interventions. CONCLUSION: Special Olympic Athletes in The Rio Grande Valley Area are an underserved population that can benefit from structured exercise implementations such as Fit5. Future interventions should aim to increase the exercise session and the retention of participants

Formulación de un plan de negocios para la exportación de aceite de aguacate

Cuando se plantea la idea de la creación de algún tipo de negocio es importante realizar un estudio ordenado y profundo sobre las variables directas o indirectas que pueden llegar a afectan la realización del mismo. Por esta razón se analizan de manera separada los entornos financiero, comercial, operativo y productivo del tipo de negocio que se desea implementar, pues al ejecutar dicho análisis se puede evaluar la viabilidad del proyecto. El presente trabajo plasma el estudio de factibilidad para la creación de una empresa exportadora de Aceite de Aguacate, por medio de la implementación del un estudio de mercado para establecer un mercado objetivo mediante una matriz de selección que tiene como base variables como afinidad cultural, idioma, importaciones del mercado objetivo, exportaciones nacionales, entre otras; por otro lado se establece cual será la estrategia de promoción, distribución y servicio. También se muestra la proyección de ventas, proceso de extracción del aceite, costos de producción, estructura organizacional, aspectos legales y financiación del proyecto. Todo lo anteriormente mencionado se plantea con el fin de poner en marcha un proyecto que nace de la idea de trabajo de grado de dos estudiantes para optar por el título de Ingeniería Industrial de la Universidad Tecnológica de Pereira y de aprovechar el alto nivel de producción de Aguacate que tiene el país, dándole un uso diferente e innovador que disminuirá el alto porcentaje de desperdicio que tiene el fruto a nivel nacional.When the idea of the creation of any sort of business is established, it is necessary to develop an organized and deep research on both direct and indirect variables that may affect the achievement of that business or trade. Due to this reason are analyzed in a separate way the financial, commercial, operative and productive environments of the business to implement, taking into account that carrying out the previous analysis the project viability can be evaluated. This writing exposes the feasibility study to create a company to export avocado oil, by means of the implementation of a marketing study, to establish a target market through a range of selection with variables such as cultural affinity, language, target market imports, national exports among others; by other side it is established what will be the promotion, distribution and service strategy. It is also shown a selling projection, oil extraction process, production costs, organizational structure, legal affairs and the project financing. What was mentioned above, is exposed in order to carry out a project that arises from the research study of two students who look forward to achieve a degree in Industrial Engineering from Universidad Tecnológica de Pereira; Moreover it is expected to take advantage of the high level of avocado production in Colombia, making use of this product in a different and innovating way, in order to decrease the wasting of this fruit in the country

Estandarización de un protocolo de extracción de ADN a partir de leche de búfalo para el diagnóstico de Leucosis

En este trabajo se modificó la técnica de salting out para la extracción de DNA en leche de búfalos de agua y se empleó la técnica de PCR para la detección del virus de la Leucosis bovina a partir de DNA en muestras de leches crudas. Para la extracción del DNA de la leche se emplearon dos métodos similares de salting out en los que se realizó la centrifugación de la leche con el uso de buffer de lisis (Tris-HCL, EDTA, NaCl), SDS, Proteinasa K y etanol. Con la única variación de que en el primer protocolo se retiró la primer capa superficial de grasa obtenida de la centrifugación, dando como resultado una concentración de ADN de 20,5µg/µl con una relación 260/280 de 1,77 mientras que en el segundo protocolo no se retiró la capa de grasa y se pudieron obtener concentraciones de ADN mayores con un promedio de 165,78 µg/µl con una relación 260/280 de 1,63, lo que permite clasificar como ADN de pureza aceptable. La obtención del DNA fue posible, demostrando así que el protocolo de extracción empleado permite obtener DNA en condiciones de pureza y cantidad suficiente a partir de pequeños volúmenes de leche. Las muestras fueron analizadas por PCR para evaluar posible presencia de BLV y se encontró que ninguna era positiva para el BLV obteniendo entonces una prevalencia del 0%
