  Concept map is a graphical tool for representing knowledge. They have been
used in many different areas, including education, knowledge management,
business and intelligence. Constructing of concept maps manually can be a
complex task; an unskilled person may encounter difficulties in determining and
positioning concepts relevant to the problem area. An application that
recommends concept candidates and their position in a concept map can
significantly help the user in that situation. This paper gives an overview of
different approaches to automatic and semi-automatic creation of concept maps
from textual and non-textual sources. The concept map mining process is
defined, and one method suitable for the creation of concept maps from
unstructured textual sources in highly inflected languages such as the Croatian
language is described in detail. Proposed method uses statistical and data
mining techniques enriched with linguistic tools. With minor adjustments, that
method can also be used for concept map mining from textual sources in other
morphologically rich languages.
