Welcome everyone to the last doctoral seminar of the semester!
On the 09.05.19, at 16.30-19:30, led by Professor Lily Díaz in Learning Centre, JUHO the doctoral student Khalil Klouche will present his on-going research titled:
Making the Information Space Explorable Through Entity-based Affordances
Starting with a critique of search engines as primary access points to the web, I advocate for greater user awareness and control as well as increased responsibility over what information is encountered. I summarize that goal as making information explorable, and investigate the related design space through the development and evaluation of various interaction and visualization techniques.
Khalil Klouche has a Master of Arts degree in Interaction Design and works since 2014 as a researcher at the Computer Science department of University of Helsinki, within Pr. Giulio Jacucci’s Ubiquitous Interaction group. Klouche designs, implements and evaluates novel interfaces for search engine that aim to support information exploration. Also a doctoral candidate at the Aalto Media department, he is the co-author of 13 published articles and the recipient of the 2017 Nokia scholarship.
Guest speaker Darius Pacauskas
is a recent Postdoctoral researcher in the Department of Art of Aalto University School of Art, Design and Architecture. He is a former Marie-Curie fellow with a computer science and social science background. His interest lies in applying ICT in various areas of research, and publications concentrated on creativity supporting technologies as well as their role in fostering collaboration and societal impact.
Aesthetics in Two Digital Worlds
(A project by Ossi Naukkarinen and Darius Pacauskas)
Aesthetics is typically seen as a theoretical, especially philosophical academic discipline focusing on questions about art, beauty, the nature of aesthetic experiences, and many other issues related to these. However, there is another, non-academic side of aesthetics where similar issues are addressed, and which is not usually considered in academic context. To investigate how these two areas of aesthetics relate to each other we applied computational text-mining techniques on Wikipedia, Google trends, YouTube, Open Library books and Web of Science datasets. We used topic modelling as a method for analysis, and used Gensim library to implemt it. Firstly, we collected data from the aforementioned sources, either by downloading from a provider, or using API’s, or scraping it with created web robot. Later we created a list of topics covering all the data we gathered, and created a topic map based on English Wikipedia articles. Later on, we imputed each dataset into the generated topic map to identify what are the most discussed topics and to what extent. Imputed datasets were related to aesthetics, e.g. Web of Science dataset included only abstracts and titles from articles that either include a keyword “aesthetics” or are from recognized venues in aesthetics discipline. Such mapping allowed us to avoid some well-known topic modeling problems. For instance, if we had applied topic modelling on separate datasets straight away, we had not been able to compare them due to differently designed topics among datasets, and topics had not been relevant due to the relatively small amount of documents imputed, as topic modelling requires a high amount of documents for informative results. To visualize results we used slightly changed version of Python library called “LDAvis”. Results allowed us to compare both areas of aesthetics and describe wideness of the gap between the two, as well as showcase a digital tool application in the field of aesthetics. This data analysis process was finished on 2017 June and an articles based on it was submitted to an international journal of aesthetics in August 2017.
