Name Finder should calculate probs for spans differently
--------------------------------------------------------
Key: OPENNLP-230
URL: https://issues.apache.org/jira/browse/OPENNLP-230
Project: OpenNLP
Issue Type: Bug
Components: Name Finder
Affects Versions: tools-1.5.1-incubating
Reporter: Jörn Kottmann
Priority: Minor
Fix For: tools-1.5.2-incubating
The name finder has a method to calculate the probability of a named entity.
The method also supports named entites which span multiple tokens. The name
finder does sequence labeling, and has a prob per token. To compute the prob of
a name span, it simply multiplies the probs of the tokens covered by the span.
Instead of multiplying it should calculate the arithmetic mean of the token
probabilities.
