Biomedical text mining applications from the biology user perspective. This figure provides a simplified general overview of some existing biomedical text mining applications from the biology user perspective. The main user query types currently addressed by existing literature processing applications are shown in the center of this figure. The outer circles represent the type of implemented applications as well as some of the corresponding systems. Note that some tools could in principle be associated to several application types (but only one of them is illustrated here). For a more detailed description of the displayed systems refer to the online tool collection repository.
