Abstract
This work aims to systematize the knowledge on emerging Intelligent Information Retrieval (IIR) practices in scenarios whose context is similar to the field of tax law. It is a part of a project that covers the emerging techniques of IIR and its applicability to the tax law domain. Furthermore, it presents an overview of different approaches for representing legal data and exposes the challenging task of providing quality insights to support decision-making in a dedicated legal environment. It also offers an overview of the related background and prior research referring to the techniques for information retrieval in legal documents, establishing the current state-of-the-art, and identifying its main drawbacks. A summary of the most appropriate technologies and research approaches of the technologies that apply artificial intelligence technology to help legal tasks is also depicted.

Abstract
The increased competitiveness in the industry sector and the pressure for companies to be more flexible to answer to the market changes, booted the investments in technologies with the aim at increasing the flexibility, productivity, and profit. To this paradigmatic change it is called digital transformation. In this context, companies try to find new way to deal with an old problem: The product production planning. Nowadays, production planning is a collaborative process that should address all supply chain network; thus, it is critical, complicated and a time-consuming process. This article focuses on the product production planning in the context of the footwear industry from a collaborative perspective, applying suppliers' assessment methods and forecasting models to optimize the production planning process, allowing companies to satisfy delivery dates. The results showed the importance of production planning in collaborative settings, but the adoption of machine learning methods reveal the need for data restructuring at the ERP and MRP levels.

Abstract
É sabido que a digitalização será o grande desígnio das empresas e a condição essencial para a sua competitividade nos próximos anos. Sabe-se também que, embora a atual pandemia COVID-19 tenha acelerado a necessidade de digitalização em diferentes áreas do negócio, sendo o seu maior impacto notado ao nível das plataformas de e-commerce, a falta de uma visão digital, para as diferentes áreas, poderá deixar as empresas sem competências para atuar de forma competitiva num mercado já global. Assim, neste artigo, adotando uma metodologia Design Science, é proposta uma solução para a obtenção de uma radiografia do nível de Maturidade Digital da indústria transformadora na região do Tâmega e Sousa - Digital Industry Survey. Procura-se desta forma criar conhecimento sobre a realidade desta indústria, que permita apoiar as empresas nos desafios colocados pelo paradigma da Indústria 4.0.

Abstract
Industry 4.0 is a trendy concept that everyone is talking about. However there are several concepts and technologies attached to Industry 4.0. The concept is considered as the most recent industrial revolution and takes us to the domains of automation, digitalization and information, among others. The concept is trendy, but sometimes firms and employees are not able to follow new trends. This paper summarizes a research on the concepts of industry 4.0 and the 9 technologies commonly associated to Industry 4.0 umbrella. Most of the literature recognizes it as something that can bring several benefits to firms. However, it is also pointed out, that the adoption of these technologies relies in several factors. In this paper the focus is the human factors. A group of 260 persons participated in a questionnaire where were asked about their perceptions on industry 4.0 and its technologies. The main objective was to find different responses to Industry 4.0 technologies, according to age, education level, gender or field of studies. In general, all the individuals present a similar approach. Main differences were found on Big Data, Augmented Reality and Simulation technologies. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Abstract
Digitalization is undoubtedly a major challenge for companies in the coming years. Applying a Design Science methodology this paper aims to describe the process for the development of a solution for obtaining an overview of the Digital Maturity in the manufacturing industry of the region of Tamega e Sousa (an industrial region located in the north of Portugal). The evaluation process consisted of a sample of 53 companies that allowed to get a first picture of the region. Summing up, it is possible to say that a digital strategy is in the companies' plans with a focus on processes digitalization. In general, an overall digital strategy for the companies is in line with the marketing and human resources, in a middle position, with a few companies taking the lead, the majority following, and some others still now awakening to this reality.
