Перевод SiDiF на Weaviate

Question

Перевод SiDiF на Weaviate

У меня есть несколько описаний онтологий в формате простого обмена данными, и я хотел бы преобразовать или импортировать их, чтобы использовать их с Weaviate.

Пример можно найти по адресу:

http://cr.bitplan.com/index.php/CrSchema (см. исходный код ниже).

Мне удалось создать классы и свойства вручную, но я не уверен, как делать отношения в стиле описания схемы Weaviates. Например, если у меня есть класс "Событие" и я хочу связать для него город, как мне это сделать, если вообще?

Вы найдете более подробную информацию о схеме на http://cr.bitplan.com/index.php/Concept:Event, а также для нее есть диаграмма UML: которая также доступна по адресу http://diagrams.bitplan.com/render/png/0x2637ba5e.png.

Можно ли вообще преобразовать ядро домена файлов SiDIF в стиль Weaviate Schema?

Сначала вам нужно определить ссылочное свойство. У них есть ссылочный класс какdataType. Например, для обозначения города:

{
  "name": "inCity",
  "description": "city reference",
  "dataType": [
    "City"
  ],
  "cardinality": "many"
}

Затем вы можете добавить ссылки через маяк:

curl -X POST "http://localhost:8080/v1/things/c60505f9-8271-4eec-b998-81d016648d85/references/hasEvent" -H 'Content-Type: application/json' -d '{"beacon": "weaviate://localhost/things/2a8d56b7-2dd5-4e68-aa40-53c9196aecde"}'

В этом примере свойство hasEvent вещи объект с uuid c60505f9-8271-4eec-b998-81d016648d85 ссылается на объект с помощью uuid 2a8d56b7-2dd5-4e68-aa40-53c9196aecde.

Проверьте справочную документацию для более подробной информации.

Вот минимальный пример использования клиента python:

#pip install weaviate-client==0.4.0
import weaviate
import time

schema = {
  "things": {
    "type": "thing",
    "classes": [
      {
        "class": "Event",
        "description": "event",
        "properties": [
          {
            "name": "acronym",
            "description": "acronym",
            "dataType": [
              "text"
            ]
          },
          {
            "name": "inCity",
            "description": "city reference",
            "dataType": [
              "City"
            ],
            "cardinality": "many"
          }
        ]
      },
      {
        "class": "City",
        "description": "city",
        "properties": [
          {
            "name": "name",
            "description": "name",
            "dataType": [
              "text"
            ]
          },
          {
            "name": "hasEvent",
            "description": "event references",
            "dataType": [
              "Event"
            ],
            "cardinality": "many"
          }
        ]
      }
    ]
  }
}


client = weaviate.Client("http://localhost:8080")

if not client.contains_schema():
    client.create_schema(schema)

event = {"acronym": "example"}
client.create(event, "Event", "2a8d56b7-2dd5-4e68-aa40-53c9196aecde")
city = {"name": "Amsterdam"}
client.create(city, "City", "c60505f9-8271-4eec-b998-81d016648d85")

time.sleep(2.0)
client.add_reference("c60505f9-8271-4eec-b998-81d016648d85", "hasEvent", "2a8d56b7-2dd5-4e68-aa40-53c9196aecde")

Можно ли вообще преобразовать ядро домена файлов SiDIF в стиль Weaviate Schema?

Это зависит от вашего варианта использования и объема работы, которую вы хотите выполнить.

Если вас интересуют только семантические возможности: в этом случае вам может вообще не понадобиться создавать сложную схему. Достаточно создать 4 классаsubject, predicate, object а также triple и загружаем все вот так.
Вы хотите загрузить определенный набор определений: вы должны воспроизвести интересующий словарь в виде сложной схемы. Weaviate не поддерживает наследование классов, поэтому вам придется как-то определять их по ссылкам. Если у вас четко определенный словарный запас, это должно быть относительно просто.
Вы хотите динамически загружать все виды словарей: я не совсем уверен, легко ли это сделать. Я предполагаю, что вам нужно создать очень сложный парсер.

Надеюсь, это поможет развлечься.
