Open Information Extraction: Current Approaches

How can smartphones be even smarter?

Smartphones are open and programmable and come with a sensing technology growing at phenomenal pace. Currently embedded sensors such as an accelerometer, camera, Gyroscope, microphone, light sensors and GPS have opened new avenues and enabled a variety of new context-based applications.

These sensing modalities are turning smartphones into cognitive phones capable of understanding our life patterns and reason about our health and well being.  While the idea of cognitive Smartphone is futuristic, early stage prototypes are taking shape in universities and research labs across the world. This seminar offers the opportunity to acquire new knowledge about the current trends towards cognitive phones and approach some of their aspects.

Course description:

  • The first part of the work should be dedicated to an exhaustive search for relevant academic papers and works related to the assigned topic.  The recommended literature should serve as example and starting point to guide the participants in this search.
  • Every participant has to deliver a 12-15 pages scientific paper on the chosen topic. The final version has to be submitted to the adviser both as hard copy and digital version by no later than one week before the presentation. Please use the ACM templates for scientific papers available in Word or LaTeX format.
  • The seminar work can be extended by a practical part, though not mandatory. This will be considered as a Bonus performance and can alleviate the expected scientific paper to 8-10 pages. Working in groups could also be arranged in this case.
  • Each participant is expected to give a presentation in front of all participants. The attendance at all presentations of the seminar is mandatory! There is no standardized Powerpoint template.
  • Each presenter is supposed to "comment" on the talk following it (except for the last presenter who will comment on the first one).  Commenting here means looking over the following topic and preparing 1-2 questions about it


Registration and topic assignment:


  1. Name, surname
  2. Student ID number
  3. Course of study and the number of the current semester
  4.  Email address.
