- Framework for a Hospitality Big Data Warehouse: The Implementation of an Efficient Hospitality Business Intelligence SystemPublication . Ramos, Celia; Martins, Daniel; Serra, Francisco; Lam, Roberto; Cardoso, Pedro; Correia, Marisol; Rodrigues, Joãoorder to increase the hotel's competitiveness, to maximize its revenue, to meliorate its online reputation and improve customer relationship, the information about the hotel's business has to be managed by adequate information systems (IS). Those IS should be capable of returning knowledge from a necessarily large quantity of information, anticipating and influencing the consumer's behaviour. One way to manage the information is to develop a Big Data Warehouse (BDW), which includes information from internal sources (e.g., Data Warehouse) and external sources (e.g., competitive set and customers' opinions). This paper presents a framework for a Hospitality Big Data Warehouse (HBDW). The framework includes a (1) Web crawler that periodically accesses targeted websites to automatically extract information from them, and a (2) data model to organize and consolidate the collected data into a HBDW. Additionally, the usefulness of this HBDW to the development of the business analytical tools is discussed, keeping in mind the implementation of the business intelligence (BI) concepts.
- A Flexible assessment platform for middle school, supported on students goalsPublication . Cardoso, Pedro; Lam, Roberto; Pereira, Rui Penha; Rodrigues, Nuno; Herdeiro, CláudiaRooted in many education system, assessment by written exams in a live only time evaluation is a traditional way to judge the student learnings. This live only time evaluation method leads to dys- functionalities such as high levels of stress and the assumption, by the students and by some teachers, that exams re ect the educational goals. This paper presents the Assessment Centers in Schools (ACiSs) project which aims to mitigate some of the identi ed problems. The nal goal of the ACiSs system is a web platform which allows students to have an out of class assessment system, reducing factor like stress by granting the possibility to complete more than one examination and consequent approval per module of the studied subjects. The ACiSs system is com- prised by a dataset of questions, properly categorized, which allows the automatic generation of exams wordings for summative and formative as- sessment. In the latter case, exams can be generated in order to mitigate individual weaknesses in the subject's curricular goals.
