In the domain of business intelligence, computers are useful for extracting scientific or technological information that may be relevant to companies. Moreover, in this context, the aim is to find some unexpected knowledge that may appear with a
low frequency. In order to automatically discover some useful knowledge from databases (patents, research publications,etc) we propose to use text mining
techniques. Nevertheless, most of these techniques can help finding some frequent information instead of unexpected one, thus, they are not well suited for business intelligence that requires a specific approach. To this end, we have designed
several new knowledge discovery measures and integrated them in the UnexpectedMiner System that is able to extract some novel information that may be of interest for the user.
We have experimented UnexpectedMiner on a database of scientific abstracts and reported the impact of the various measures on the efficiency of the system.
