GroundX Ingest for Parsing

Comprehensive Document Parsing for Modern Applications

In this guide, we’ll introduce EyeLevel’s X-Ray, a modern parser designed to extract high quality data from complicated real-world documents. X-Ray employs cutting edge parsing techniques which are specifically designed to support modern workflows like RAG, Agents, and Document Summarization, allowing developers to connect data from human-centric documents to LLM powered applications.

X-Ray in a Nutshell

You can think of X-Ray as a cocktail of document understanding and advanced parsing approaches packaged together under a single API. To give you an idea, these are some of the components which X-Ray employs to understand human-centric documents:

• Bespoke document understanding models to detect key elements within documents.
• Advanced OCR processes which facilitate textual extraction from a variety of document representations.
• A repairing and reformatting pipeline that improves parse interpretability.
• A re-contextualization system that promotes fully contextualized summarizations of parsed results.

The upshot is a system which can extract complete ideas from complex documents, and represent those ideas in a way which is easy for both developers and LLMs to understand.

See it for yourself

X-Ray’s fine tuned vision model is one of the most critical components of the system. Over the last 4 years, EyeLevel has collected a comprehensive set of documents from a variety of domains which have been used to train, in our opinion, the highest quality vision model for understanding complex real-world documents to date. You can use this demo to get an idea of how X-Ray works with your documents.

Or you can get started with our APIs by following these simple steps:

How to use X-Ray

1) Creating a Bucket

Once you have a GroundX API key you may wish to create a bucket. Buckets can be used to organize documents into different groupings, which can be useful for certain applications. We can list all available buckets via List Buckets, and create a new bucket via Create Bucket.

1
from groundx import GroundX, Document
2
import urllib.request, json, time
3
4
# authenticating
5
client = GroundX(
6
    api_key="YOUR_API_KEY",
7
)
8
9
# creating a new bucket
10
bucket_response = client.buckets.create(
11
  name="parsed_documents_bucket"
12
)
13
14
# storing the bucket_id
15
bucket_id = bucket_response.bucket.bucket_id

3) Uploading Documents

Uploading documents to a GroundX bucket will automatically trigger X-Ray. There are a variety of uploading options which might be useful for a variety of use cases. In this example we’re uploading a document which is stored locally using Ingest Local.

1
ingest_response = client.ingest(
2
    documents=[
3
        Document(
4
            bucket_id=bucket_id,
5
            file_name="sample",
6
            file_path="sample.pdf",
7
            file_type="pdf"
8
        )
9
    ]
10
)

4) Querying Upload Status

Ingesting returns a process_id, which can be used with Get Processing Status to query the progress of the upload. This code checks the status of the process every 10 seconds until ingestion is done.

1
while (True):
2
    ingest_response = client.documents.get_processing_status_by_id(
3
        process_id=ingest_response.ingest.process_id,
4
    )
5
    if (ingest_response.ingest.status == "complete" || ingest_response.ingest.status == "cancelled"):
6
        break
7
    if (ingest_response.ingest.status == "error"):
8
        raise ValueError('Error Ingesting Document')
9
    print(ingest_response.ingest.status)
10
    time.sleep(3)

5) Getting X-Ray Results

Now that our documents are fully uploaded we can get all the documents in our bucket via Get Document. We only uploaded a single document, so we can get the one and only document at index 0, and then get the URL in which the X-Ray output is stored.

1
# Getting parsed documents from the bucket
2
document_response = client.documents.lookup(
3
    id=bucket_id
4
)
5
6
# Getting the X-Ray parsing results for one of the documents
7
xray_url = document_response.documents[0].xray_url
8
with urllib.request.urlopen(xray_url) as url:
9
    data = json.loads(url.read().decode())
10
    print(data)

6) Interpreting X-Ray Results

X-Ray provides a rich set of results which may be useful in a variety of use cases. Here are some noteworthy outputs of X-Ray:

• fileKeywords: A list of keywords which describe the document
• fileSummary: A summary of the entire document
• boundingBoxes: Key regions within the document which contain meaningful content.
• contentType: The type of content a certain chunk is. Textual paragraph, graphical figures, or tables.
• json: A reformatted representation of graphs and figures in a json format, useful for both LLM and programatic workflows.
• narrative: A reformatted representation of graphs and figures in a narrative format, often useful in LLM applications.
• sectionSummary: A contextually summarized representation of a particular section of the document.

This is the full structure of an X-Ray parse:

1
// Successful lookup response
2

3
  "fileType": "string", // One of the supported file types

  "language": "string", // Language detected on the first page of your document during processing
