> The Entity Co-Mention engine detect repeating mentions of already detected Entities. The typical example is
> Barack Obama stated [..] Obama also [..]
> But as there exists a City called Obama [1] in Japan an EntityLinking engine linking against a vocabulary containing both Barack Obama AND Obama will link the mention of Obama with the City.
> The Co-Mention engine will however detect that the mention of Obama is most likely a co-mention of Barack Obama. Therefore it should also be able to adapt the confidence values of existing suggestion for Obama.
> This issue will introduce a new configuration property for the Entity Co-Mention Engine
>     enhancer.engines.comention.adjustExistingConfidence
> This property will take values in the range [0..1). Confidence values of existing suggestions will be multiplied with '1-{value}'. Meaning that configuring '0.0' will not change existing confidence values (deactivate this features).
> The default value will be set to '0.33'.
> This change will be applied to both the trunk and the 0.12 releasing branch
