Which Auto Classification Method Works?
February 1, 2015
Unfortunately A. Lancichinetti, et al do not deliver a consumer reports type analysis in “High Reproducibility and High Accuracy Method for Automated Topic Classification.” The paper does raise some issues that keyword search vendors with add on categorization do not often explain to licensees. In a nutshell, classification is often chugging along with 65 to 80 percent accuracy. Close enough for horseshoes, Gustav Dirichlet is here. A couple of thoughts:
- Dirichlet died in 1822. Yep, another of the math guys from the past.
- The method is described as “state of the art.”
- Bounded content sets of sci tech information yield more accurate classification.
How do these methods work on WhatsApp messages in gang slang?
