Exploratory search for scientific articles

It is intuitively clear that the search for scientific publications often has many characteristics of a research search. The purpose of this paper is to formalize this intuitive understanding, explore which research tasks of scientists can be attributed to research search, what approaches exist to solve a research search problem in general, and how they are implemented in specialized search engines for scientists. We researched existing works regarding information seeking behavior of scientists and the special variant of a search called exploratory search. There are several types of search typical for scientists, and we showed that most of them are exploratory. Exploratory search is different to information retrieval and demands special support from search systems. We analyzed seventeen actual search systems for academicians (from Google Scholar, Scopus and Web of Science to ResearchGate) from the exploratory search support aspect. We found that most of them didn’t go far from simple information retrieval and there is a room for further improvements especially in the collaborative search support.
