The sec-parser project simplifies extracting meaningful information from SEC EDGAR HTML documents by organizing them into semantic elements and a tree structure. Semantic elements might include section titles, paragraphs, and tables, each classified for easier data manipulation. This forms a semantic tree that corresponds to the visual and informational structure of the document. If you're familiar with the Image Semantic Segmentation concept, it's the same but applied to HTML documents.

This tool is especially beneficial for Artificial Intelligence (AI), Machine Learning (ML), and Large Language Models (LLM) applications by streamlining data pre-processing and feature extraction.

sec-parser is versatile and can be applied in various scenarios, including but not limited to:

• Financial Analysis: Extract financial data from 10-Q and 10-K filings for quantitative modeling.
• Risk Assessment: Evaluate risk factors or Management's Discussion and Analysis sections for qualitative analysis.
• Regulatory Compliance: Assist in automating compliance checks for the legal teams.
• Flexible Filtering: Easily filter SEC documents by sections and types, giving you precisely the data you need.

• Academic Research: Facilitate large-scale studies involving public financial disclosures, sentiment analysis, or corporate governance exploratory.
• Analytics Ready: Integrate parsed data seamlessly into popular analytics tools for further analysis and visualization.

• Cutting-Edge AI for SEC EDGAR: Apply advanced AI techniques like MemWalker to navigate and extract and transform complex information from SEC documents efficiently. Learn more in our blog post: Cutting-Edge AI for SEC EDGAR: Introducing MemWalker.
• AI Applications: Leverage parsed data for various AI tasks such as text summarization, sentiment analysis, and named entity recognition.
• Data Augmentation: Use authentic financial text to train and test machine learning models.

• Causal Analysis: Use parsed data to understand cause-effect relationships in financial data, beyond mere correlations.
• Predictive Modeling: Enhance predictive models by incorporating causal relationships, leading to more robust and reliable predictions.
• Decision Making: Aid decision-making processes by providing insights into the potential impact of different actions, based on causal relationships identified in the data.

• LLM Compatible: Use parsed data to facilitate complex NLU tasks with Large Language Models like ChatGPT, including question-answering, language translation, and information retrieval.

These use-cases demonstrate the flexibility and power of sec-parser in handling both traditional data extraction tasks and facilitating more advanced AI-driven analysis.

This guide will walk you through the process of installing the sec-parser package and using it to extract the "Segment Operating Performance" section as a semantic tree from the latest Apple 10-Q filing.

First, install the sec-parser package using pip:

pip install sec-parser

To run the example code in this README, you'll also need the sec_downloader package:

pip install sec-downloader

Once you've installed the necessary packages, you can start by downloading the filing from the SEC EDGAR website. Here's how you can do it:

from sec_downloader import Downloader

# Initialize the downloader with your company name and email
dl = Downloader("MyCompanyName", "email@example.com")

# Download the latest 10-Q filing for Apple
html = dl.get_filing_html(ticker="AAPL", form="10-Q")

Now, we can parse the filing HTML into a list of semantic elements:

# Utility function to make the example code a bit more compact
def print_first_n_lines(text: str, *, n: int):
    print("\n".join(text.split("\n")[:n]), "...", sep="\n")

import sec_parser as sp

elements: list = sp.Edgar10QParser().parse(html)

demo_output: str = sp.render(elements)
print_first_n_lines(demo_output, n=7)

TopSectionTitle: PART I  —  FINANCIAL INFORMATION
TopSectionTitle: Item 1.    Financial Statements
TitleElement: CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS (Unaudited)
SupplementaryText: (In millions, except number of ...housands and per share amounts)
TableElement: Table with 24 rows, 80 numbers, and 1058 characters.
SupplementaryText: See accompanying Notes to Conde...solidated Financial Statements.
TitleElement: CONDENSED CONSOLIDATED STATEMEN...OMPREHENSIVE INCOME (Unaudited)
...

We can also construct a semantic tree to allow for easy filtering by parent sections:

tree = sp.TreeBuilder().build(elements)

demo_output: str = sp.render(tree)
print_first_n_lines(demo_output, n=7)

TopSectionTitle: PART I  —  FINANCIAL INFORMATION
├── TopSectionTitle: Item 1.    Financial Statements
│   ├── TitleElement: CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS (Unaudited)
│   │   ├── SupplementaryText: (In millions, except number of ...housands and per share amounts)
│   │   ├── TableElement: Table with 24 rows, 80 numbers, and 1058 characters.
│   │   ├── SupplementaryText: See accompanying Notes to Conde...solidated Financial Statements.
│   ├── TitleElement: CONDENSED CONSOLIDATED STATEMEN...OMPREHENSIVE INCOME (Unaudited)
...

Your turn to explore the capabilities of sec-parser! With the tools and examples provided, you can now dive into parsing and analyzing SEC filings.

The semantic elements and tree structures created by the parser will serve as a solid foundation for your financial analysis and research tasks with the tools of your choice.

For a tailored experience, consider using our free and open-source library for AI-powered financial analysis:

To ensure your code remains functional even when we change the internal structure of sec-parser, it's recommended to avoid deep imports. Here is an example of a deep import (not recommended):

Instead, use the suggested ways to import modules from sec-parser:

• import sec_parser as sp. This imports the main package as sp. You can then access its functionalities using sp. prefix.

• from sec_parser import SomeClass: This allows you to directly use SomeClass without any prefix.

• import sec_parser.semantic_tree: This imports the semantic_tree submodule, and you can access its classes and functions using semantic_tree. prefix.

• from sec_parser.semantic_tree import SomeClass: This imports a specific class SomeClass from the semantic_tree submodule.
