• Front-paging online newspapers 

      Koutsaftikis, I.; Nanas, N.; Vavalis, M. (2013)
      Online newspapers and magazines still find it difficult to let readers discover and just read news. A plethora of stories on the front (home) page, overuse of complex grids, vast navigation lists and advertising immaturity ...
    • Immune inspired information filtering in a high dimensional space 

      Nanas, N.; Kodovas, S.; Vavalis, M.; Houstis, E. (2010)
      Adaptive Information Filtering is a challenging computational problem that requires a high dimensional feature space. However, theoretical issues arise when vector-based representations are adopted in such a space. In this ...
    • Immune learning in a dynamic information environment 

      Nanas, N.; Vavalis, M.; Kellis, L. (2009)
      In Adaptive Information Filtering, the user profile has to be able to define and maintain an accurate representation of the user's interests over time. According to Autopoietic Theory, the immune system faces a similar ...
    • Personalised news and scientific literature aggregation 

      Nanas, N.; Vavalis, M.; Houstis, E. (2010)
      Content-based filtering can be deployed for personalised information dissemination on the web, but this is a possibility that has been largely ignored. Nowadays, there are no successful content-based filtering applications ...
    • Revisiting evolutionary information filtering 

      Nanas, N.; Kodovas, S.; Vavalis, M. (2010)
      Adaptive Information Filtering seeks a solution to the problem of information overload through a tailored representation of the user's interests, called user profile, which constantly adapts to changes in them. Evolutionary ...
    • Words, antibodies and their interactions 

      Nanas, N.; Vavalis, M.; De Roeck, A. (2010)
      Jerne's idiotypic network theory stresses the importance of antibody-to-antibody interactions and provides possible explanations for self-tolerance and increased diversity in the immune repertoire. In this paper, we use ...
