KnowMiner is a software framework offering a rich set of knowledge discovery functionalities.

Services for increasing information quality in unstructured information are valuable for knowledge discovery. Knowledge discovery involves analytical processes in which data is transformed and processed to identify relevant information and extract new, previously undiscovered, meaningful knowledge.

KnowMiner primarily focuses on knowledge discovery in large textual data sets where it provides a wide range of high-performance algorithms and techniques.
These are complemented by a set of visual analysis components which, by adequately combining human capabilities with machine processing, provide support for interactive analytical reasoning.

Thus, from the outside KnowMiner can be seen as a tool for bridging the divide between large, heterogeneous document repositories and users seeking to gain insight into knowledge hidden within very large piles of data.
