Extracting Key Information from Contracts
Legal professionals often need to quickly identify and extract key information from contracts, such as the names of the parties involved, important dates, and specific obligations. Automating this process can save significant time and reduce the risk of overlooking critical details. By using Python, you can write scripts to scan contract text and pull out this essential information, making contract review and management more efficient.

Alpha agrees to deliver the goods by April 1, 2023. Beta will make payment on or before April 15, 2023. """ # Extract dates using simple string methods dates = [] for word in contract_text.split(): # Look for months as a simple way to find dates if word in ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]: # Assume the next two words are day and year idx = contract_text.split().index(word) date = " ".join(contract_text.split()[idx:idx+3]) dates.append(date) print("Extracted dates:", dates)
To understand how this extraction works, start by searching for keywords that indicate the type of information you want. In the case of dates, months of the year are a reliable starting point. The code above splits the contract text into words and checks each word to see if it matches a month name. When a month is found, it assumes the following two words are the day and year, and combines them using string slicing. This simple logic works for standard date formats and is easy to adapt for similar patterns. For more complex contracts, you might need to search for different keywords or use more advanced string operations, but the basic approach remains: identify a marker, then extract the surrounding text.
