CS Other Presentations
Besides Colloquiums, the Department of Computer Science at the University of Cyprus also holds Other Presentations (Research Seminars, PhD Defenses, Short Term Courses, Demonstrations, etc.). These presentations are given by scientists who aim to present preliminary results of their research work and/or other technical material. Other Presentations serve as a forum for educating Computer Science students and related announcements are disseminated to the Department of Computer Science (i.e., the csall list):RSS Directions

If one accepts that the ability to pass the Turing Test is a useful indicator — if not a defining property — of machine intelligence, then one should also accept the importance of endowing machines with the ability to read. But before realizing this goal, one first needs to make more precise what “reading” even means. The task of (Recognizing) Textual Entailment can be seen as capturing a key element of reading: the ability to draw (or at least recognize) inferences from a given piece of text. The original operational definition of the task appeals to human judgment to determine soundness of inference. Such an inherently subjective and anthropocentric definition of the task precludes it, however, from being applicable to machines that acquire the ability to read in an autonomous and highly scalable manner. This talk discusses a definition for textual entailment that retains the formal objective aspects of logical entailment, yet it embraces the statistical nature of the operational definition, and avoids rigidness. The proposed definition views text as a partial depiction of some underlying hidden reality, mapped into a piece of text through the text’s author. Textual entailment is, then, the task of accurately recovering information about this underlying reality. High performance on this task can be provably (under typical assumptions) achieved by training a machine on a corpus of text relevant to the domain of interest, without the need for human supervision to identify the inferences that are expected to be drawn from each piece of text. Experimental results confirm the applicability of the approach in a real-world setting.
Loizos Michael is a lecturer at Open University of Cyprus (since 2009). He is the founder and director of the Computational Cognition research lab (since 2010), and the academic head of a graduate program of studies in Information Systems (since 2011). Before joining OUC he held a visiting lecturer position at University of Cyprus (2008–2009). He was educated at University of Cyprus, where he received a B.Sc. in Computer Science with a minor degree in Mathematics (2002). He continued his education at Harvard University, where he received an M.Sc. and a Ph.D. in Computer Science (2003 and 2008, respectively). His research focuses on the formal and principled understanding of cognitive processes such as learning and reasoning, and how those are employed by humans and other biological organisms in their everyday lives. Specific areas of interest include: commonsense reasoning, temporal and default reasoning, argumentation, computational learning theory, computational evolution theory, computational story understanding, nature-inspired computation, distributed and multi-agent systems.
