PNET (Polish Named Entity Triggers) contains a list of external and internal evidences (trigger words) of Polish named entities (NEs). An external or an internal NE evidence is a word or a list of words which appears frequently in the vicinity or inside named entities and is a good indicator of these NEs' types. For instance ''aktor'' ('actor') is an external evidence for person names (as in ''aktor [Zbigniew Buczkowski]''), while ''von'' is an internal evidence for the same type (''[John von Neumann]''). Many words can be both external and internal evidences, e.g. ''jezioro'' ('lake') is a external evidence in ''jezioro [Mamry]'' ('[Mamry] lake') and an internal evidence in ''Jezioro Białe'' ('[White Lake]'). External and internal NE evidences can be used in automatic NE recognition via grammar-based or machine-learning methods. The list has been created semi-automatically from a subset of Polish Wikipedia whose infobox types and categories were manually mapped on the [[http://nkjp.pl|NKJP]] NE typology.

Triggers for Polish Named Entities
PNET (Polish Named Entity Triggers) contains a list of external and internal evidences (trigger words) of Polish named entities (NEs). An external or an internal NE evidence is a word or a list of words which appears frequently in the vicinity or inside named entities and is a good indicator of these NEs' types. For instance aktor ('actor') is an external evidence for person names (as in aktor [Zbigniew Buczkowski]), while von is an internal evidence for the same type ([John von Neumann]). Many words can be both external and internal evidences, e.g. jezioro ('lake') is a external evidence in jezioro [Mamry] ('[Mamry] lake') and an internal evidence in Jezioro Białe ('[White Lake]'). External and internal NE evidences can be used in automatic NE recognition via grammar-based or machine-learning methods.
