Claim 7:
8. A 2D map generation program stored on a non-transitory recording medium for causing a computer to execute a process of generating a 2D map in which a plurality of pieces of target information is plotted on a 2D plane based on a feature vector generated from target information,
the target information is a word, and
the feature vector is a vector having, as a plurality of elements, index values indicating word contributes to which text and to what extent
the program for causing the computer to function as:
a word extraction means that analyzes m texts (m is an arbitrary integer of 2 or more), and extracts n words (n is an arbitrary integer of 2 or more) from the m texts;
a text vector computation means that converts each of the m texts into a q-dimensional vector (q is an arbitrary integer larger than 3) according to a predetermined rule, thereby computing m text vectors including q axis components;
a word vector computation means that converts each of the n words into a q-dimensional vector according to a predetermined rule, thereby computing n word vectors including q axis components;
an index value computation means that obtains each of inner products of the m text vectors and the n word vectors, thereby computing m×n index values reflecting a relationship between the m texts and the n words;
a feature vector specification means that specifies, as the feature vector, a word index value group including index values of m texts for one of the n words;
2D processing means that generates 2D latitude and longitude information by performing a dimension compression process on the feature vector; and
map generating means that generates the 2D map based on a plurality of pieces of latitude and longitude information generated by the 2D processing means for the plurality of pieces of target information.
