Notice (2008/Nov/27)
Sorry for delay in release of new version. Currently, the tool is being re-implemented with a new algorithm. In a preliminary experiment, the detection accuracy is much improved, but the memory consumption is also much increasing (the tool will require 64bit PC). Thank you in advance for waiting.

Tool Vaci (tentative)

What's tool Vaci

Tool Vaci extracts relations between identifiers in source code, with context of the identifiers, in order to classify the identifiers. This enables the user:

• to find a kind of inconsistency in naming of identifiers in source code of a product, or
• to investigate changes / trends of identifier names between versions of a product.

Todo

• Use "frequrent itemset technique" in detection.
• Apply to gapped clones.
