Create language models for medical experts and for non-expert from Swedish medical documents and use these in order to enhance an information retrieval system to retrieve documents on a, for the user, suitable level of expertise.
When searching for documents on a medical topic health care professionals and lay persons most likely are interested in finding documents on different levels of expertise. Most information retrieval systems do not adjust the returned ranked list of documents to the users background.
As Språkbanken has a Swedish medical test collection with documents marked for target group: Doctors or Patients this could be used to make language models for the two user groups which then could be used to adjust the results to the users needs.
The approach is to make language models for medical expert language and for lay persons. The objective is to describe differences between the sublanguages and to use these models to retrieve documents suited for the user.
