> The FST linking engine already allows to configure in percentage how much of a processable chunk (typically noun phrases) need to match so that a suggestion is accepted. This is done by using the "enhancer.engines.linking.minChunkMatchScore" property. The default is > 50%.
> While this way of configuration is great for chunks created by NamedEntityAnnotations it is not always well suited for detected noun phrases as those may select larger sections of a sentence. E.g. "goalie Mathias Lange (Iserlohn Roosters)" will not match any Entity in a vocabulary as it contains 5 matchable tokens but both the player "Mathias Lange" and the Team name "Iserlohn Roosters" do only represent two of them.
> In such cases the configuration of a fixed lower limit of the number of (matchable) Tokens that need to match within a Chunk can be preferable.
> For this configuration the FST linking engine will use the "Min Matched Tokens (enhancer.engines.linking.minFoundTokens)" property of the EntityLinker configuration. The default will be "2".
> The FST linking Engine will accept tokens the either confirm with "enhancer.engines.linking.minChunkMatchScore" or "enhancer.engines.linking.minFoundTokens".
> NOTE: those configuration do only apply for Tokens within a processable Chunk (typically a Noun Phrase)
