About

I got a Ph.D. in Informatics, Artificial Intelligence branch, at Universidade Nova de Lisboa, 1994.

I am currently Associate Professor at the Informatics Engineering Department, Engineering Faculty of the University of Porto (FEUP), where I teach in the areas of databases, data warehouses, digital preservation and discrete mathematics.

I have participated in the creation of the joint Doctoral Program in Computer Science (MAP-i) of the Universities of Minho, Aveiro and Porto and I integrate its Scientific Committee since 2007. I participated in the creation of the Information Science Bachelor (2001) and Master (1997) Programs jointly taught by the Engineering and Humanities Faculties and I integrate the corresponding Scientific Committees.

I am a member of the Scientific Council of the Engineering Faculty since 2010.

I have led the development team of SIGARRA, the U.PORTO Academic Information System, from 1996 to 2010.

I am a Researcher at INESC TEC since 1985, integrating its Administration since 2015. My main research interests are in Information Management, Digital Preservation, and Databases. I have been the leader of the projects FCT DBPreserve on preservation of databases, Gulbenkian APDIC on digital preservation plans and EEA Grant SeaBioData. Currently, I integrate the project FCT TAIL on research data management.

I have collaborated between  2000 and 2010 in the project Cooperation with the National University of Timor Leste led by the Foundation of the Portuguese Universities, as coordinator of the Informatics Engineering bachelor (2006-2010).

I am a member of the Engineers Portugal association where I have belonged to the Board of Admission and Qualification from 2010 to 2016.

Planning and managing data for Smart Cities: An application profile for the UrbanSense project

Abstract
Aiming to improve sustainability and life quality, urban space research is prompting an intensive use of communication and information technologies. With it, researchers are also facing more challenges regarding research data management and therefore seeking clear guidelines and tools for proper data organization, sharing and reuse. In the context of a smart cities research project, UrbanSense, held in the city of Porto, we proposed a data management plan, to support researchers from the moment they start to collect data up to the point of data publication. We also developed an ontology for the description of smart cities data, validated by UrbanSense researchers. Descriptions based on this ontology were evaluated by external parties, after the data was published in an institutional data repository. © 2018 IEEE.

Abstract
Research datasets include all kinds of objects, from web pages to sensor data, and originate in every domain. Concerns with data generated in large projects and well-funded research areas are centered on their exploration and analysis. For data in the long tail, the main issues are still how to get data visible, satisfactorily described, preserved, and searchable. Our work aims to promote data publication in research institutions, considering that researchers are the core stakeholders and need straightforward workflows, and that multi-disciplinary tools can be designed and adapted to specific areas with a reasonable effort. For small groups with interesting datasets but not much time or funding for data curation, we have to focus on engaging researchers in the process of preparing data for publication, while providing them with measurable outputs. In larger groups, solutions have to be customized to satisfy the requirements of more specific research contexts. We describe our experience at the University of Porto in two lines of enquiry. For the work with long-tail groups we propose general-purpose tools for data description and the interface to multi-disciplinary data repositories. For areas with larger projects and more specific requirements, namely wind infrastructure, sensor data from concrete structures and marine data, we define specialized workflows. In both cases, we present a preliminary evaluation of results and an estimate of the kind of effort required to keep the proposed infrastructures running.  The tools available to researchers can be decisive for their commitment. We focus on data preparation, namely on dataset organization and metadata creation. For groups in the long tail, we propose Dendro, an open-source research data management platform, and explore automatic metadata creation with LabTablet, an electronic laboratory notebook. For groups demanding a domain-specific approach, our analysis has resulted in the development of models and applications to organize the data and support some of their use cases. Overall, we have adopted ontologies for metadata modeling, keeping in sight metadata dissemination as Linked Open Data.

Database Preservation: The DBPreserve Approach

Abstract
In many institutions relational databases are used as a tool for managing information related to day to day activities. Institutions may be required to keep the information stored in relational databases accessible because of many reasons including legal requirements and institutional policies. However, the evolution in technology and change in users with the passage of time put the information stored in relational databases in danger. In the long term the information may become inaccessible when the operating system, database management system or the application software is not available any more or the contextual information not stored in the database may be lost thus affecting the authenticity and understandability of the information. This paper presents an approach for preserving relational databases for the long-term. The proposal involves migrating a relational database to a dimensional model which is simple to understand and easy to write queries against. Practical transformation rules are developed by carrying out multiple case studies. One of the case studies is presented as a running example in the paper. Systematic implementation of the rules ensures no loss of information in the process except for the unwanted details. The database preserved using the approach is converted to an open format but may be reloaded to a database management system in the long-term.
