Interpretation of a term map
• Size:– The larger a term, the higher the frequency of occurrence of the term
• Distance:– In general, the smaller the distance between two terms, the higher the relatedness of the
terms, as measured by co-occurrences
– The horizontal and vertical axes have no special meaning; maps can be freely rotated and flipped
• Colors:– Colors indicate clusters of closely related terms
