- Framework for classroom student grading with open-ended questions: a text-mining approachPublication . Vairinhos, Valter Martins; Pereira, Luís Agonia; Matos, Florinda; Nunes, HelenaThe purpose of this paper is to present a framework based on text-mining techniques to support teachers in their tasks of grading texts, compositions, or essays, which form the answers to open-ended questions (OEQ). The approach assumes that OEQ must be used as a learning and evaluation instrument with increasing frequency. Given the time-consuming grading process for those questions, their large-scale use is only possible when computational tools can help the teacher. This work assumes that the grading decision is entirely a teacher’s task responsibility, not the result of an automatic grading process. In this context, the teacher is the author of questions to be included in the tests, administration and results assessment, the entire cycle for this process being noticeably short: a few days at most. An attempt is made to address this problem. The method is entirely exploratory, descriptive and data-driven, the only data assumed as inputs being the texts of essays and compositions created by the students when answering OEQ for a single test on a specific occasion. Typically, the process involves exceedingly small data volumes measured by the power of current home computers, but big data when compared with human capabilities. The general idea is to use software to extract useful features from texts, perform lengthy and complex statistical analyses and present the results to the teacher, who, it is believed, will combine this information with his or her knowledge and experience to make decisions on mark allocation. A generic path model is formulated to represent that specific context and the kind of decisions and tasks a teacher should perform, the estimated results being synthesised using graphic displays. The method is illustrated by analysing three corpora of 126 texts originating in three different real learning contexts, time periods, educational levels and disciplines.
- Knowledge Management on PMO’s Perspective: A Systematic ReviewPublication . Cunha, José Adson; Figueiredo, José; Matos, Florinda; Thomaz, JoãoMuch of the work developed in organizations occurs as projects and this tendency is crescent. The Project Management Office(PMO) is an organizational entity with responsibilities related to the centralization and coordination of projects under its domain. In fact, PMOs can fill many different roles or functions in different organizations.
- The Relationship Between Intellectual Capital and Information Technology: Findings Based on a Systematic ReviewPublication . Cunha, Livia; Cunha, José Adson; Matos, Florinda; Thomaz, JoãoThe world is experiencing a knowledge-based economy with a revolution in information technology, innovation, and telecommunications. The rise of the "new economy", driven by information and knowledge, has led to an increased interest in intellectual capital theory, which aims to manage intangible assets of organizations. Firms belonging to technology and knowledge-based industries recognize intellectual capital as the key knowledge base that contributes to the creation of a competitive advantage for the firm. This paper aims to answer the question "How are Intellectual Capital (IC) and Information Technology (IT) related?" through a systematic review based on four steps: 1) search conduction; 2) selection of papers based on their titles and abstracts; 3) content analysis of selected papers; 4) evidence mapping and discussions. The analyzed papers were categorized into five themes: "Statistical analysis or case study in IT companies from the Intellectual Capital perspective"; "IT as a tool for Intellectual Capital Management"; "Intellectual Capital or technology knowledge assets influencing innovation and development", "Intellectual Capital assets to evaluate a technology" and "Intellectual Capital theory as a way to understand and share knowledge in IT projects". Our findings evidenced that the Human Capital was the main dimension studied by the authors, followed by Structural Capital and Relational Capital. We believe that this work may help to clarify on Intellectual Capital Management procedures into Information Technology projects, thus opening new topics for future research.
