In this paper we present the retrieval and adaptation mechanisms used in our information system on travel medicine, docQuery. The retrieval method’s main feature is an overall improved accuracy of retrieval results’ similarities through a more diverse distribution of similarities over the retrieved result sets. Its underlying idea is the execution of several consecutive retrievals on one case b...

We study the classifier quantification problem in the context of the topical opinion retrieval, that consists in estimating proportions of the sentiment categories in the result set of a topic. We propose a methodology to circumvent individual classification allowing a real-time sentiment analysis for huge volumes of data. After discussing existing approaches to quantification, the novel propos...

In this short note we prove, by means of classical fixed point index, an affine version a Birkhoff--Kellogg type theorem in cones. We apply our result to discuss the solvability class boundary value problems for functional differential equations subject conditions. illustrate theoretical results example.
