This put up exhibits methods to combine Amazon Bedrock with the AWS Serverless Knowledge Analytics Pipeline structure utilizing Amazon EventBridge, AWS Step Features, and AWS Lambda to automate a variety of information enrichment duties in a cheap and scalable method.

Answer overview

The AWS Serverless Knowledge Analytics Pipeline reference structure gives a complete, serverless resolution for ingesting, processing, and analyzing information. At its core, this structure incorporates a centralized information lake hosted on Amazon Easy Storage Service (Amazon S3), organized into uncooked, cleaned, and curated zones. The uncooked zone shops unmodified information from numerous ingestion sources, the cleaned zone shops validated and normalized information, and the curated zone comprises the ultimate, enriched information merchandise.

Constructing upon this reference structure, this resolution demonstrates how enterprises can use Amazon Bedrock to boost their information belongings by automated information enrichment. Particularly, it showcases the mixing of the highly effective FMs obtainable in Amazon Bedrock for producing concise summaries of unstructured paperwork, enabling end-users to shortly grasp the essence of data with out sifting by in depth content material.

The enrichment course of begins when a doc is ingested into the uncooked zone, invoking an Amazon S3 occasion that initiates a Step Features workflow. This serverless workflow orchestrates Lambda features to extract textual content from the doc based mostly on its file sort (textual content, PDF, Phrase). A Lambda perform then constructs a payload with the doc’s content material and invokes the Amazon Bedrock Runtime service, utilizing state-of-the-art FMs to generate concise summaries. These summaries, encapsulating key insights, are saved alongside the unique content material within the curated zone, enriching the group’s information belongings for additional evaluation, visualization, and knowledgeable decision-making.

The serverless nature of this structure gives inherent advantages, together with computerized scaling, seamless updates and patching, complete monitoring capabilities, and strong safety measures, enabling organizations to deal with innovation reasonably than infrastructure administration.

The next diagram illustrates the answer structure.

Let’s stroll by the structure chronologically for a better take a look at every step.

Initiation

The method is initiated when an object is written to the uncooked zone. On this instance, the uncooked zone is a prefix, nevertheless it is also a bucket. Amazon S3 emits an object created occasion and matches an EventBridge rule. The occasion invokes a Step Features state machine. The state machine runs for every object in parallel, so the structure scales horizontally.

Workflow

The Step Features state machine gives a workflow to deal with totally different file sorts for textual content summarization.  Recordsdata are first preprocessed based mostly on the file extension and corresponding Lambda perform.  Subsequent, the recordsdata are processed by one other Lambda perform that summarizes the preprocessed content material. If the file sort is just not supported, the workflow fails with an error. The workflow consists of the next states:

• CheckFileType – The workflow begins with a Selection state that checks the file extension of the uploaded object. Primarily based on the file extension, it routes the workflow to totally different paths:
  • If the file extension is .txt, it goes to the IngestTextFile state.
  • If the file extension is .pdf, it goes to the IngestPDFFile state.
  • If the file extension is .docx, it goes to the IngestDocFile state.
  • If the file extension doesn’t match any of those choices, it goes to the UnsupportedFileType state and fails with an error.
• IngestTextFile, IngestPDFFile, and IngestDocFile – These are Process states that invoke their respective Lambda features to ingest (or course of) the file based mostly on its sort. After ingesting the file, the job strikes to the SummarizeTextFile state.
• SummarizeTextFile – That is one other Process state that invokes a Lambda perform to summarize the ingested textual content file. The perform takes the supply key (object key) and bucket identify as enter parameters. That is the ultimate state of the workflow.

You may lengthen this code pattern to account for various kinds of recordsdata, together with audio, footage, and video recordsdata, through the use of companies like Amazon Transcribe or Amazon Rekognition.

Preprocessing

Lambda lets you run code with out provisioning or managing servers. This resolution comprises a Lambda perform for every file sort. These three features are half of a bigger workflow that processes various kinds of recordsdata (Phrase paperwork, PDFs, and textual content recordsdata) uploaded to an S3 bucket. The features are designed to extract textual content content material from these recordsdata, deal with any encoding points, and retailer the extracted textual content as new textual content recordsdata in the identical S3 bucket with a special prefix. The features are as follows:

• Phrase doc processing perform:
  • Downloads a Phrase doc (.docx) file from the S3 bucket
  • Makes use of the python-docx library to extract textual content content material from the Phrase doc by iterating over its paragraphs
  • Shops the extracted textual content as a brand new textual content file (.txt) in the identical S3 bucket with a cleaned prefix
• PDF processing perform:
  • Downloads a PDF file from the S3 bucket
  • Makes use of the PyPDF2 library to extract textual content content material from the PDF by iterating over its pages
  • Shops the extracted textual content as a brand new textual content file (.txt) in the identical S3 bucket with a cleaned prefix
• Textual content file processing perform:
  • Downloads a textual content file from the S3 bucket
  • Makes use of the chardet library to detect the encoding of the textual content file
  • Decodes the textual content content material utilizing the detected encoding (or UTF-8 if encoding can’t be detected)
  • Encodes the decoded textual content content material as UTF-8
  • Shops the UTF-8 encoded textual content as a brand new textual content file (.txt) in the identical S3 bucket with a cleaned prefix

All three features observe the same sample:

1. Obtain the supply file from the S3 bucket.
2. Course of the file to extract or convert the textual content content material.
3. Retailer the extracted and transformed textual content as a brand new textual content file in the identical S3 bucket with a special prefix.
4. Return a response indicating the success of the operation and the placement of the output textual content file.

Processing

After the content material has been extracted to the cleaned prefix, the Step Features state machine initiates the Summarize_text Lambda perform. This perform acts as an orchestrator in a workflow designed to generate summaries for textual content recordsdata saved in an S3 bucket. When it’s invoked by a Step Features occasion, the perform retrieves the supply file’s path and bucket location, reads the textual content content material utilizing the Boto3 library, and generates a concise abstract utilizing Anthropic Claude 3 on Amazon Bedrock. After acquiring the abstract, the perform encapsulates the unique textual content, generated abstract, mannequin particulars, and a timestamp right into a JSON file, which is uploaded again to the identical S3 bucket with a specified prefix, offering organized storage and accessibility for additional processing or evaluation.

Summarization

Amazon Bedrock gives an easy strategy to construct and scale generative AI functions with FMs. The Lambda perform sends the content material to Amazon Bedrock with instructions to summarize it. The Amazon Bedrock Runtime service performs an important position on this use case by enabling the Lambda perform to combine with the Anthropic Claude 3 mannequin seamlessly. The perform constructs a JSON payload containing the immediate, which features a predefined immediate saved in an atmosphere variable and the enter textual content content material, together with parameters like most tokens to pattern, temperature, and top-p. This payload is distributed to the Amazon Bedrock Runtime service, which invokes the Anthropic Claude 3 mannequin and generates a concise abstract of the enter textual content. The generated abstract is then acquired by the Lambda perform and included into the ultimate JSON file.

If you happen to use this resolution to your personal use case, you possibly can customise the next parameters:

• modelId – The mannequin you need Amazon Bedrock to run. We suggest testing your use case and information with totally different fashions. Amazon Bedrock has quite a lot of fashions to supply, every with their very own strengths.
