Jussi Karlgren of Spotify to speak on information access as it relates to media at iConference 2020

13 Feb 2020 18:32 | iSchools News (Administrator)

With this second installment in our series on iConference 2020 keynote speakers, we focus on Prof. Jussi Karlgren, whose talk will take place the afternoon of Wednesday, March 25. Standard conference registration rates are in effect through Feb. 17, after which time late rates go into effect.

Karlgren is a principal research scientist at Spotify and one of the founding partners of the text analysis company Gavagai. He has worked with language technology and interaction with information since 1987. His main research interest is on how to design a learning knowledge representation to handle the continuously changing form and content of human information and to meet the broad variety of human information needs an information system meets with, including entertainment and diversion. He believes human language to be very well designed representation and that technology to handle it should embrace its characteristics instead of viewing them as problems. Karlgren has worked on stylistic variation and genres in language and on large scale semantic spaces for application e.g. to sentiment analysis.

Karlgren’s presentation is titled Information Access for Evolving Media Usage. "The media usage habits of the population at large change, which has effects for the educational system, for memory institutions, for the media industry, and therefore for those of us who develop technology for information access,” he tells us. “Many of the current changes are easy to observe through introspection or through observing how people in our vicinity consume media and information: people read text on screens; watch lectures and educational material in video clips; listen to literary material and to short written texts superimposed on brief video clips to their near and dear; and stream music and movies instead of purchasing physical objects to place in shelves in their homes.

“There are very obvious challenges for technology having to do with how we make documents and their content accessible for search and exploration across media types, and we do not quite know what effects today's changes have on tomorrow’s media usage.

"This talk will give some examples, based in part on experiences from Spotify, a large music and podcast streaming service, and discuss one of the less obvious challenges: how to evaluate and validate new technology solutions. We know how to measure quality for systems designed to fulfil expressly formulated known information needs, but how can we measure quality of a system designed to entertain and delight? How can we assess the usefulness of systems for digital scholars? And what are the underlying assumptions that have governed the make-up of the experimental benchmarking of today's information systems?"
