About the position

The Department of Computer Science has a vacancy for a PhD-position in mining streaming data, in a project funded by DNB (Norway's largest financial services group) and NTNU. The project’s focus is on technologies and architectures for dealing with large-scale real-time data processing, with emphasis on solving business challenges within the banking and finance sector.

In the financial sector, a wide range of data sources can be used both to understand customers, as well as the financial market in general. These data sources may contain both structured data (from typical financial services), as well as textual data (from communication with users, news media, or social media). Common for much of the interesting data, is that it is in the form of data streams that needs to be processed in real-time. The topic of this PhD position is effective information analysis (i.e., querying, searching or mining) on such data streams.

The position reports to Head of Department

Main duties and responsibilities

Much of the data relevant for financial services has either an implicit or explicit time dimension, and often also a geographical aspect. The PhD student will develop techniques for effective information analysis on such data, in one of the following areas (depending on interest and background of the candidate):

  • Algorithmic: Scalable algorithms for retrieval and mining of spatio-temporal streaming data
  •  Information retrieval: Searching and mining spatio-temporal-textual streaming data

The main supervisor will be Prof. Kjetil Nørvåg, and the candidate is also expected to work together with other researchers in his group.
