> 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.
