Abstract
There is a lot of work in text categorization using only the title and abstract of the papers. However, in a full paper there is a much larger amount of information that could be used to improve the text classification performance. The potential benefits of using full texts come with an additional problem: the increased size of the data sets. To overcome the increased the size of full text data sets we performed an assessment study on the use of feature selection methods for full text classification. We have compared two existing feature selection methods (Information Gain and Correlation) and a novel method called k-Best-Discriminative-Terms. The assessment was conducted using the Ohsumed corpora. We have made two sets of experiments: using title and abstract only; and full text. The results achieved by the novel method show that the novel method does not perform well in small amounts of text like title and abstract but performs much better for the full text data sets and requires a much smaller number of attributes.

Abstract
The tourism sector has become one of the most important engines of economic growth for many countries. With the evolution of Information and Communication Technologies, new opportunities have arisen for a reengineering in the way the various tourism and hospitality industries interact with tourists. Equally, new possibilities open to the entities that vision to promote the patrimony and endogenous products of their regions. Information and Communication Technologies are today one of the most critical areas for the success of tourism and how tourist destinations can be promoted. Tourists, increasingly a digital generation, expect that the access to information and services be done in an innovative, immersive and contextualized way, through the use of technologies that are embedded in their daily lives. This article discusses the touristic routes creation process and the role of Information and Communication Technologies in the creation and support of touristic routes. Also, a technological model is presented in its conceptual perspective, as well the functional modelling of its main components and features. © 2019 International Business Information Management Association (IBIMA).

Abstract
The Internet of Things (IoT) represents a new technological revolution expected to impact all aspects of our daily lives in the future. Generation Z is foreseen as playing a fundamental role in the adoption of this type of technology, namely because of their growing importance as a consumer segment, their global role in the society, and in particular their close relationship with technology. However, extant literature on the adoption of IoT disregarded this segment. This paper aims to fulfill this gap, by exploring their knowledge, perceptions, and intentions of adopting IoT. After considering the main contributions in the consumer behavior literature regarding IoT, a qualitative approach was adopted, and 7 semi-structured interviews were conducted with Portuguese consumers aged 18-22. Content analysis was performed following the recommendations by Bardin (1977). The results showed that although Generation Z is not familiar with the concept of the IoT, they expressed a strong desire to integrate IoT technology in their lives, being open to its adoption in all fields of application, including for personal use, at home, and for work. One of the conclusions is that in order to foster the IoT adoption by this Generation, the functional benefits (performance, price, comfort, and safety) should be emphasized, so that the main risks perceived are weakened, namely the financial, performance, and physical risks.

Abstract
This paper exposes the applicability study of the oedometer test to an existing silty sand soil, from the city of Braganza, with the purpose to verify the applicability of this test to soils with fines in his composition, in a region with predominance of granite residual soils, considering that the granulometric curve of these soils are substantially different from the granulometric curves of the soils that are usually tested. For this, two types of soils were collected, namely intact samples of a silty sand, and a disturbed soil sample whose grains size distribution curve built into laboratory corresponds to a high plasticity silt. Due to the greater predominance of fines in the high plasticity silt, the mechanical behaviour of this soil, more conditioned by forces of an electrochemical nature, serves as a comparative term to the mechanical behaviour of the undisturbed samples of the silty sand, with a behaviour less dependent on these forces, thus allowing to show applicability of the test to soils with lower percentage of fines, with a more pronounced gravitational behaviour and, therefore, more atypical to the oedometer test. From the results obtained for silty sand, a high value of the immediate settlement was verified after each applied load cycle. Thus this observation, the beginning of the consolidation process demands high accurate recording of the settlement that clearly identify the time that primary consolidation begins. In this way, the implementation of the data acquisition system, allowing the correct reading of the consolidation beginning, minimizing human errors, expands the spectrum of soils existing in the region that can be study by the consolidation problematics point of view.
