Stanley (2000), that we would need a space for the next step of the methodology by transforming
the correlation coefficient into the ultrametric distance (see also Situngkir, 2000 for some discussion
about ultrametric space in market analysis),
δultrametric ( mh, m 2) = ʌ/2 (1 - P( ml, m 2) )

Third, the obtained distance matrix can be used to build the phylomemetic tree by using the
dendogram or cladistics techniques. As it has been discussed in detail by Khanafiah & Situngkir
(2006), a useful algorithm that can be used to have clearer view of the clustered artifacts is the so-
called UPGMA (Unweighted Pair Group Method with Arithmetic mean). This is a popular bottom-up
data clustering method used in genetics. In this tree construction technique, one assumes the
constant evolutionary changes. In short, the algorithm examines the structure present in a pairwise
distance matrix to then construct the dendrogram. Then at each step, the nearest 2 clusters are
combined into a higher-level cluster. The distance between any of clusters A and B is taken to be the
average of all distances between pairs of objects "a" in A and "b" in B. By using this method, we can
examine whether our visualization has conform with some analytical observation in general.
3. Case of Study: Tradition-Inspired Buildings in Indonesia
The diversity of Indonesia is represented in a so called place, Taman Mini Indonesia Indah, a park in
which the diversity of Indonesian and this has become an exemplification of our acquisition of the
visualization offered by the cladistics of memes: phylomemetic tree. We listed the buildings
reflecting the 26 places of old provisions of Indonesia in the administrative area of provinces.

The diversities of architectural buildings in Nusantara
It is worth emphasizing that most of the buildings do not necessarily represent certain ethnicities. In
the park, the Indonesian traditional architectures reflect the traditional houses (or palaces) of ethnic
groups within the area of Indonesian local provincial administrations. Thus, the numbers of
ethnicities and social identities shown in each province and consequently the objects becoming the
