Abstract Attribute-Based Prediction of File Properties(13)

We present evidence that attributes that are known to the file system when a file is created, such as its name, permission mode, and owner, are often strongly related to future properties of the file such as its ultimate size, lifespan, and access pattern.

against the ABLE(unconstrained)decision trees. MABLE:trees induced with only the inode attributes (mode,uid,gid).

NABLE:trees induced with only?le names.

Figure4compares the predication accuracies for ABLE,MABLE and NABLE.For the purpose of clarity, this?gure only shows the accuracy for three of our bi-nary properties(size,write-only,and?le name lifespan); the results for our other properties are similar.The?g-ure shows that ABLE usually outperforms both MABLE and NABLE.This tells that some multi-way associations exist between the?le name attributes and other attributes that allow us to make more accurate predictions when all are considered.An example of a multi-way association would be that the lifespan of a?le depends on both the ?le name and the user who created the?le.
