Claim 2:
3. The 2D map generation apparatus according to claim 2,
when x texts (x is an arbitrary integer of 1 or more) are added as analysis targets in addition to the m texts,
the word extraction unit analyzes m+x texts, and extracts the n words from the m+x texts,
the text vector computation unit converts each of the m+x texts into a q-dimensional vector according to a predetermined rule, thereby computing m+x text vectors including q axis components,
the word vector computation unit converts each of the n words into q-dimensional vector according to a predetermined rule, thereby computing n word vectors including q axis components,
the index value computation unit obtains each of inner products of the m+x text vectors and the n word vectors, thereby computing (m+x)×n index values reflecting a relationship between the m+x texts and the n words,
the feature vector specification unit further specifies a text index value group including index values of n words for one text as an additional feature vector for each of the x texts,
the 2D processing unit further generates 2D latitude and longitude information for each of the x texts by performing a dimension compression process on the additional feature vector for each of the x texts using a function having the same effect as when a dimension compression process is performed on the feature vector for each of the m texts, and
the map generation unit generates the 2D map based on m pieces of latitude and longitude information generated for the m texts and x pieces of latitude and longitude information generated for the x texts by the 2D processing unit.
