Neural Question Answering at BioASQ 5B

This paper describes our submission to the 2017 BioASQ challenge. We participated in Task B, Phase B which is concerned with biomedical question answering (QA). We focus on factoid and list question, using an extractive QA model, that is, we restrict our system to output substrings of the provided text snippets. At the core of our system, we use FastQA, a state-of-the-art neural QA system. We extended it with biomedical word embeddings and changed its answer layer to be able to answer list questions in addition to factoid questions. We pre-trained the model on a large-scale open-domain QA dataset, SQuAD, and then fine-tuned the parameters on the BioASQ training set. With our approach, we achieve state-of-the-art results on factoid questions and competitive results on list questions

Exploring customer interaction and management response in luxury hospitality through online reviews in social media

This dissertation aims to understand the feelings expressed by consumers on online reviews, regarding the different dimensions that comprise a luxurious hotel experience, alongside with how management response reflects guests 'feedback. To contextualize this modern online interaction, the research comprises the analysis of relationship marketing and customer engagement concepts, as basis theoretical constructs, alongside with social media marketing and electronic word-of-mouth. Giving this broad knowledge concerning the type of relationship established between hotels and guests nowadays, it was possible to investigate much further the hospitality sector, highlighting online reviews and how they have been promoted a deeper study about consumers 'experiences. Afterwards, one analysed the process behind hotels' response to the online available feedback, translated into the concept of management response, in terms of its conceptualization, benefits and potential strategies. A netnographic study was conducted on two luxury hotel brands - Hilton and Marriott, and eight hotels were selected - four of 4-star and four of 5-star - on London. Two hundred reviews were extracted for each property on Tripadvisor, side by side with hotels 'responses, so in the end 2864 online comments were gathered between February and March 2019.Esta dissertação visa compreender os sentimentos expressados pelos consumidores nas "online reviews", sobre os diferentes elementos que compõe uma experiência hoteleira luxuosa, assim como de que forma a resposta dos hotéis reflete esse mesmo "feedback". Para contextualizar esta moderna interação "online", a investigação compreende o estudo dos conceitos de "relationship marketing" e "customer engagement", como pilares teóricos, bem como de "social media marketing" e "electronic word-of-mouth". Com um conhecimento alargado sobre o tipo de relação estabelecida entre hotéis e hóspedes nos dias de hoje, foi possível estudar o sector hoteleiro em específico, dando destaque às "online reviews" e à forma como têm contribuindo para um estudo mais aprofundado das experiências dos consumidores. Depois, analisou-se o processo que envolve a resposta dos hotéis ao "feedback" disponível "online", traduzido na noção de "management response", em termos da sua conceptualização, benefícios e possíveis estratégias. Foi realizado um estudo netnográfico a duas marcas pertencentes ao sector hoteleiro de luxo - Hilton e Marriott, tendo sido oito hotéis selecionados - quatro de 5 estrelas e quatro de 4 estrelas - na cidade de Londres. Foram extraídas 200 "reviews" sobre cada uma das propriedades no Tripadvisor, assim como a resposta dos respectivos hotéis, traduzindo-se num total de 2864 comentários analisados entre Fevereiro e Março de 2019

The Impact of Dashboard Visualizations in CISCO’s: Operations & Decision-Making Processes

Internship Report presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Knowledge Management and Business IntelligenceBusiness Intelligence has been growing significantly in recent years and has been more and more used in companies that strive for innovation and to always be up to date with their competitors. With this, there’s an increased need to have specialized professionals that deliver new perspectives and insights of looking at the data and allow for the companies to grow wisely and efficiently. It is crucial to understand in what ways the concept of Business Intelligence being implemented and a regular practice has an impact on the companies and how they function, that being the main subject of study of the report. This report is with regards to the one-year internship started in March of 2022 as a Business Operations Analyst at CISCO, with the aim of conducting a deep analysis and translating the data into actional business insights and assist business functions to create value for key strategic initiatives, namely by gathering data, creating dynamic visualizations through dashboards, and analyzing/investigating their impact and importance on the firm’s efficiency and how it influences its decision-making processes. With this internship I was able to not only learn but to also experience in first-hand the importance of business intelligence and have a practical example of how the outcomes changed when compared to previous solutions and practices

O regime de comunicação prévia no combate ao planeamento fiscal abusivo

Esta tese tem como objecto o regime da comunicação prévia, introduzido em Portugal pelo Decreto-Lei nº 29/2008, de 25 de Fevereiro, e insere-se no âmbito do combate ao planeamento fiscal abusivo.O objecto do presente estudo é examinar o contexto, as características e as principais questões fiscais que originaram e decorrem do regime da comunicação prévia e questionar se o combate ao planeamento fiscal abusivo justifica ou não uma disposição especial anti-abuso que poderá também ela ser considerada abusiva. Este estudo realiza ainda uma análise comparada desta medida especial anti-abuso, com medida idêntica noReino Unido, país cuja Lei inspirou de forma mais expressiva a Lei Portuguesa.Este estudo centra-se na análise crítica do regime da comunicação prévia e identifica as principais questões suscitadas pelas suas regras, avalia as suas vantagens e fragilidades e retira conclusões sobre a eficácia, clareza e o rigor desta medida antiabuso.Além disso, este estudo analisa a compatibilização do regime da comunicação prévia, com o segredo profissional.Neste estudo conclui-se que é verdade que o regime da comunicação prévia, apresenta as mais diversas debilidades, devido, essencialmente, ao legislador Português, que vão desde falhas notórias de rigor e precisão, à falta de razoabilidade e ponderação, e que foram aqui, deveras, analisadas. Todavia, conclui-se também que este regime, recebendo as merecidas correcções, representará, como actualmente representa, um mecanismo de grande utilidade para a Administração Fiscal, no combate aoplaneamento fiscal abusivo, que só assumindo uma posição igualmente agressiva, poderá, pelo menos para já, tentar repor a integridade do sistema fiscal, a justadistribuição do encargo tributário e a pureza da actividade económica

International Standard ISO 9001 - An Artificial Intelligence View

ISO 9001 is recognized as a Quality Management Systems standard, i.e., it is the primary phase of a process of constant enhancement that will provide an organisation with the necessary management tools to improve working practices. Indeed, it provides a framework and a set of principles aimed at ensuring a common sense approach to the management of an organization in order to consistently satisfy customers and other stakeholders. Therefore, and in order to add value to ISO 9001, this work focuses on the development of a decision support system, which will allow companies to be able to meet the needs of customers by fulfilling requirements that reflect either the effectiveness or the non-effectiveness of an organization. The procedures for knowledge representation and reasoning used are based on an extension to the Logic Programming language, allowing the handling of incomplete, contradictory and even forbidden data, information and/or knowledge. The computational framework is centred on Artificial Neural Networks to evaluate customer’s satisfaction and the degree of confidence that one has on such a happening
