Better or unclear

Precision is the ratio of true positives to positives: how many hits are correct? Yield is the ratio of true positives to the total number of true positives and false negatives: how many hits that should have been found were actually found. This two-dimensional perspective does not allow for any clear-cut estimation.

Table

If name matching Method A results in lower yield and precision values than Method B, then A is a poorer method than B. If, however, Method C results in higher yield values but lower precision values than B, what matters is whether yield or precision is more important. In this case, C is different when compared to B, but not fundamentally better or worse.

 

Complete Revision of the Federal Data Protection Act

The complete revision's draft of the Federal Data Protection Act is currently in political consultation. Data Protection is to be increased by giving people more control over their private data as well as reinforcing transparancy regarding the handling of confidential data.
