HEalth teXt Analysis network in the Nordic and Baltic countries 

Project manager: Hercules Dalianis
Additional participants from DSV: Gunnar Nilsson, Martin Hassel, Sumithra Velupillai, Maria Skeppstedt, Aron Henriksson, Sara Brissman, Hideyuki Tanushi.
Project duration: July 2009 - 30 okt 2012
Funding: Nordforsk. 

Hexanord is a researcher network with participants involved in health science, computer science and information technology in the Nordic and Baltic countries. The overall aim of the network is to explore the differences and similarities in the texts in electronic patient records in the various countries by means of text mining. Another aim of the network is to strengthen cooperation between the participating universities in the Nordic and Baltic countries.

The goals of the network

  • To exchange experiences, tools and knowledge within text mining of health records
  • To create a research training school in text mining of electronic health records in the Nordic countries
  • To stimulate the mobility of researchers througout the Nordic countries
  • To create synthetic electronic health records (see below)
  • To disseminate the networks' results and knowledge to the healthcare sector, but also to the public and other interest group

Electronic patient records

For some years, almost all patient records are electronic. This means that the vast amount of information is now more available for research. The fact that all information now is available in electronic format implies a great opportunity to develope automated tools for textual analysis of the records.

One aim of HEXAnord project is to produce a synthetic database of patient records. The information contained in the records are retrieved from existing records, but will be deconstructed so that it not will be possible to identify the individuals behind the records. HEXAnord is going to develop such databases for all the languages represented in the network. To develop the databases you first need to analyse the differences in the patient records from the respective countries, both in terms of structure, style and content.
