Table Question Answering

The Table Question Answering is one of the Natural Language Processing tasks supported by Hugging Face.

Using the huggingface_table_question_answering filter.

The result will be converted to a JSON string from huggingface_table_question_answering. You could decompress the JSON string and use the result by itself.

Sample 1 - send the data from variable by set tag:

{% set data = [
  {
    "repository": "vulcan-sql",
    "topic": ["analytics", "data-lake", "data-warehouse", "api-builder"],
    "description":"Create and share Data APIs fast! Data API framework for DuckDB, ClickHouse, Snowflake, BigQuery, PostgreSQL"
  },
  {
    "repository": "accio",
    "topic": ["data-analytics", "data-lake", "data-warehouse", "bussiness-intelligence"],
    "description": "Query Your Data Warehouse Like Exploring One Big View."
  },
  {
    "repository": "hell-word",
    "topic": [],
    "description": "Sample repository for testing"
  }
] %}

-- The source data for "huggingface_table_question_answering" needs to be an array of objects.
SELECT {{ data | huggingface_table_question_answering(query="How many repositories related to data-lake topic?") }}

Sample 1 - Response:

[
  {
    "result": "{\"answer\":\"COUNT > vulcan-sql, accio\",\"coordinates\":[[0,0],[1,0]],\"cells\":[\"vulcan-sql\",\"accio\"],\"aggregator\":\"COUNT\"}"
  }
]

Sample 2 - send the data from req tag:

{% req artists %}
  SELECT * FROM artists
{% endreq %}

{% set question = "List display name where gender are female?" %}

SELECT {{ products.value() | huggingface_table_question_answering(query=question, model="microsoft/tapex-base-finetuned-wtq", wait_for_model=true, use_cache=true) }}

Sample 2 - Response:

[
  {
    "result": "{\"answer\":\"Irene Aronson, Ruth Asawa, Isidora Aschheim, Geneviève Asse, Dana Atchley, Aino Aalto, Berenice Abbott\",\"coordinates\":[[8,1],[16,1],[17,1],[23,1],[25,1],[29,1],[35,1]],\"cells\":[\"Irene Aronson\",\"Ruth Asawa\",\"Isidora Aschheim\",\"Geneviève Asse\",\"Dana Atchley\",\"Aino Aalto\",\"Berenice Abbott\"],\"aggregator\":\"NONE\"}"
  }
]

use_cache	N	true	There is a cache layer on the inference API to speedup requests we have already seen
wait_for_model	N	false	If the model is not ready, wait for it instead of receiving 503. It limits the number of requests required to get your inference done
