Conclusions
Conclusions

  • Failed to predict CDS movements from news:

    • no surprise, financial markets and web activities are two complex systems, only partially interrelated

  • http://NewStream.ijs.si portal:

    • useful insights into news (entities, volume, sentiment, tag clouds, drill-down)

  • Publications:

  • KraljNovak, P., Grčar, M., Mozetič, I.

  • Visual analytics of financial news with NewStream,

  • Submitted to Information Processing & Management journal, Elsevier,

  • Special Issue “Interactive Analysis of weakly structured & unstructured data”, 2013.

  • Vavpetič, A., Kralj Novak, P., Grčar, M., Mozetič, I., Lavrač, N.

  • Semantic data mining of financial news articles,

  • Proc. Intl. Conf. Discovery Science, pp. 294-307, Springer (LNAI 8140), Singapore, October 6-9, 2013.
