Extracting Data from Messy Documents using Chat GPT
Hello, my name is Brandon Roberts, and I'm a data journalist. In this article, I will guide You on how to use Chat GPT to extract data from messy documents. But before we dive into the details, let's first understand the background of data extraction from PDFs.
Background on Data Extraction from PDFs
Government institutions are required to share public documents with citizens and journalists. However, these documents are often messy and unstructured, which makes it challenging to extract useful data. This task falls on the shoulders of data journalists who are responsible for cleaning up, organizing, and transforming these documents into structured formats, such as spreadsheets.
Using Chat GPT for Data Extraction
Typically, data journalists use Python scripts to extract data from PDFs. However, this process can be time-consuming and complex, especially when dealing with documents that have varying formats. This is where Chat GPT comes into play.
Converting to a Regular Text File
The first step in using Chat GPT for data extraction is to convert the messy document into a regular text file. Tools like PDF Plumber can be utilized to accomplish this task efficiently. Once the file is converted, it can be used as input for Chat GPT.
Extracting Json Representation of Text
With the document in text format, you can leverage Chat GPT to extract a Json representation of the text. By prompting Chat GPT with the request to return a Json representation, you can obtain structured data from the messy document. This can save a considerable amount of time compared to manually writing Python scripts.
Handling Complex Formats
Messy documents often have complex formats, making it difficult to parse the data accurately. For example, police use of force spreadsheets may have irregularities in the arrangement of fields and values. Writing a parser for such documents can be challenging, but Chat GPT can help simplify the process.
Challenges in Parsing Police Use of Force Data
Police use of force data often presents unique challenges for data journalists. These challenges include parsing field names and values and handling situations where multiple officers are involved in a single complaint.
Parsing Field Names and Values
In police use of force data, the arrangement of field names and their corresponding values can be inconsistent. This inconsistency arises when the data for a field is positioned below the field name. Writing a parser to handle these situations can be tedious and time-consuming.
Working with Multiple Officers per Complaint
Another challenge in parsing police use of force data is dealing with complaints involving multiple officers. Extracting and organizing data for each officer, along with their respective complaints, can be complicated. However, Chat GPT can assist in automating this process.
Extracting Data from Weirdly Formatted Tables
Weirdly formatted tables often pose a significant hurdle for data journalists. These tables may have unconventional arrangements and inconsistent splitting of data elements. Writing a Python script to parse such tables can be a nightmare. However, Chat GPT can prove to be an excellent solution for extracting data from these challenging tables accurately.
Dealing with Large Document Collections
Sometimes, the task of data extraction involves processing large collections of documents, making manual copying and pasting impractical. In such cases, a tool called Chat GPT Document Extraction script can come to the rescue.
Introducing the Chat GPT Document Extraction Script
The Chat GPT Document Extraction script enables the extraction of data from multiple documents in an automated manner. By providing the script with input data in either text file or Json format, along with a specified Json schema, you can automate the extraction process for a large collection of messy documents.
Input Types and Json Schemas
The Chat GPT Document Extraction script supports various input types, including text files and Json data. Additionally, specifying a Json schema allows you to define the structure of the desired output. This ensures that the extracted data adheres to the specified schema, making it easier to work with.
Limitations of Chat GPT for Data Extraction
While Chat GPT proves to be a powerful tool for data extraction, it is essential to be aware of its limitations. Chat GPT may introduce mistakes in data extraction, making it necessary to manually verify the results. Therefore, it is not advisable to solely rely on Chat GPT for data extraction without human oversight.
Conclusion
In this article, we explored the use of Chat GPT for data extraction from messy documents. We discussed background information on data extraction from PDFs and explained how Chat GPT can simplify the extraction process. We also highlighted the challenges faced when parsing police use of force data and dealing with weirdly formatted tables. Finally, we introduced the Chat GPT Document Extraction script for handling large document collections. While Chat GPT provides great assistance, it is crucial to exercise caution and double-check the extracted data for accuracy.
