Abstract
Table 11: Accuracy in reconstructing the Austronesian family tree with the ABVD and ASJP database. This table shows the Robinson-Foulds distance, the Quartet Distance and their generalizations, between the Austronesian language tree (inferred with both the ASJP and the ABVD database) and its relative Ethnologue-Classification for the languages shown in Table.10. In this case we only used the LDN definition of distance between lists of words and FastSBiX as distance-based algorithm to infer the trees. All the measures indicate that the ABVD database allows for a more accurate reconstruction of this language tree.
['—', '[BOLD] ABVD  [BOLD] Neighbour-Joining', '[BOLD] ABVD  [BOLD] FastME', '[BOLD] ABVD  [BOLD] FastSBiX', '[BOLD] ASJP  [BOLD] Neighbour-Joining', '[BOLD] ASJP  [BOLD] FastME', '[BOLD] ASJP  [BOLD] FastSBiX']
The most accurate tree is intended to be the tree, within the ones inferred by the three considered algorithms, that features lower distance from the Ethnologue classification. The LDN definition of distance between languages, which allows for faster computations, has been used here.
