Patent ID: 7401070

Claim:
A flow data generation method, comprising: (a) storing, in a first storage unit, a set of binomial relation data including first term data, second term data, and relation types between the first term data and the second term data, and in a second storage unit, position data which are data on position where each value of the first term data and second term data exists in the set of binomial relation data storing in the first storage unit; (b) extracting first binomial relation data including first term data to be a start point of flow data from the set of binomial relation data in the first storage unit; (c) associating the start point as a first parent node with second term data of the first binomial relation data as a first child node; (d) adding a relation type of the first binomial relation data to an arc of the first binomial relation data; (e) searching the set of the binomial relation data in the first storage unit for third binomial relation data including first term data identical to second term data of second binomial relation data by referring to the position data in the second storage unit; (f) associating the first term data of the third binomial relation data as a second parent node with second term data of the third binomial relation data as a second child node; (g) adding a relation type of the third binomial relation data to an arc of the third binomial relation data; (h) repeating the (e) searching, (f) associating, and (g) adding to generate a partial tree including a root identical to the second term data of the first binomial relation data; and (i) displaying the particle tree.
