Abstract [en]

National cancer registries collect cancer related information from multiple sources and make it available for research. Part of this information originates from pathology reports, and in this pre-study the possibil- ity of a system for automatic extraction of information from Norwegian pathology reports is investigated. A set of 40 pathol- ogy reports describing breast cancer tissue samples has been used to develop a rule based system for information extraction. To validate the performance of this system its output has been compared to the data produced by experts doing manual encod- ing of the same pathology reports. On av- erage, a precision of 80%, a recall of 98% and an F-score of 86% has been achieved, showing that such a system is indeed fea- sible.
