We previously discussed the framework of the image of towns which promote themselves as
Koedo/Shokyoto (little Edo/Kyoto) through an analysis of the words on sightseeing brochures published by local governments or tourist offices. The former studies focused on the contents of their historical value, we found 132 Value groups which represents hierarchical meaning network of their value. In this report, we focus on the structure of Value groups which was not considered in the previous reports, to clarify hierarchical structure of each town's historical value (Table1, Fig. 1, 2 and 3).
Firstly, structure of all Value groups were examined individually from following four aspects of the distribution of Value objects, component elements of Value groups; Form of layer, No. of 2nd level connection, Level of subdivision and Focused connection. Combination of No. of 2nd level connection and Level of subdivision was considered, two contrasting forms of structure were found; one has a large number of subdivision mainly on the upper layer, the other has a large number of subdivision mainly on the lower layer. In these structure, primal Value objects which start the tree structure have different characteristics as follow; one of the former structure's Value object is richness of meaning, one of the latter structure's Value object is integration of meaning (Fig. 4, 5, 6 and 7).
Secondly, according to the placement of Value objects' History which directly related to Edo/Kyoto, Historical character of Value groups was grouped into following four categories; Diverted-history main, Diverted-general, General-diverted, General-history main (Fig. 8, 9 and 10). Diverted-history main was related to less subdivided structure, and Diverted-general was related to much subdivided structure.
Finally, in order to capture the whole hierarchical structure of each town, the set of Value groups in each sightseeing brochure was considered (Fig. 11, 12, 13 and 14). As for Integrate type towns which contain one value group,
Koedo towns tend to have the structure with Focused connection, and
Shokyoto towns tend to have the structure mainly subdivided on the lower layer. Dispersed type towns which contain several value groups were divided into following two types based on the comparison of their structural complexity; Master-servant type and Parallel type. The latter was divided further into Parallel-equal type and Parallel-different type. As for Master-servant type,
Koedo towns tend to place much emphasis on the Value groups directly related to Edo. As for Parallel type,
Koedo towns were more related to Parallel-different type,
Shokyoto towns were more related to Parallel-equal type. These results suggest distinctive hierarchical structure of the image of
Koedo and Shokyoto:
Koedo makes sparcity and density of meaning in the value network, to emphasize the elements which directly connected to image of Edo.
Shokyoto towns less make density difference of that, to express consistent image of towns as miniaturized Kyoto.
