Improved schema definition in the SimpleKGPipeline

[stellasia]

Description

Adds the ability to specify some entities or relationships as dict in the SimpleKGPipeline, adding a description and property list (both optional):

valid_entities = [
  "Location",  # this or the next items are equivalent
  {
    "label": "Event",
  },
  {
    "label": "Game",
    "description": "A match between two persons",
  },
  {
    "label": "Organization",
    "properties": [
      {"name": "name", "type": "STRING"},
      {"name": "createdIn", "type": "INT", "description": "Creation year"},
    ]
  },
  {
    "label": "Person",
    "description": "A human being",
    "properties": [
      {"name": "name", "type": "STRING"},
      {"name": "birthDate", "type": "DATE"},
    ]
  },
]
