In the sample output above please note that the Infinit.e harvester automatically generates the following fields as appropriate:
- event_type
"Event", "Fact", "Summary"
The "event_type" field sub-categorizes the "event" object into one of three types, "Event", "Fact", or "Summary". Examples provided below should make the distinction clearer, but it can be simply described as follows:- "Event": link multiple entities (via "entity1_index", "entity2_index", "geo_index") and represent a transient activity (eg travel)
- "Fact": link multiple entities like "Events" but represent (transient or permanent) relationships (eg being president)
- "Summary": generally link 1 entity to a free text (eg a quotation: "Obama says...").
