A computer program product, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising:

• identifying, by a processor using a topic identification system, topic information for a source topic-domain in a corpus;
• extracting, by the processor, an entity from the source topic-domain;
• tagging, by the processor, the entity with the topic information to obtain a tagged entity that includes a tag specifying the topic information;
• storing the tagged entity in a memory device;
• and
• performing, by the processor, downstream processing of the tagged entity in a natural language processing pipeline using the tag of the tagged entity as an additional data point.
