Questions regarding each of the invited seminars 
Note: answers should be concise, with a maximum of 1 page per question.

Grades for the answers provided to the short quiz questions are published online, together with the materials used in each of the presentations.

Prof. Francisco Couto - Information Systems ( slides )

  1. Describe what is linked data, and explain if link data is necessarily open and free (i.e., if you believe that it isn't, detail an example scenario where the data should be kept private, but the principles/benefits of using linked data would still make sense). With basis on the presentation, explain also how existing linked datasets can be evaluated/ranked in terms of quality/accessibility, and clearly explain the properties that an open linked dataset should strive to ensure.
  2. The presentation also discussed how text mining methods can be used to enrich the linked data cloud. Discuss the advantages/disadvantages of rule-based versus learning-based approaches for text mining biomedical documents.

Prof. Daniel Gonçalves - Computer Graphics, Multimedia, and HCI ( slides )

  1. Explain the role of abstractions as one of the core differences between information visualization and scientific data visualization.
  2. Explain the role of context as one of the core differences when managing/retrieving personal information and other types of information.

Prof. Alysson Neves Bessani - Distributed, Operating and Networked Systems ( slides1 , slides2 )

  1. Describe some of the challenges associated to current research on operating systems, in connection to new hardware architectures.
  2. Briefly explain what is BFT-SMaRt, and how it works.

Prof. Rui Maranhão - Software Engineering ( slides )

  1. Explain how the spectrum-based fault localization procedure, introduced in the lecture, proceeds to pinpointing program elements more likely to contain faults.
  2. Explain what is spectrum-based reasoning, and explain how these techniques improve over spectrum-based fault localization.
