def extract_domain_knowledges(input_file, output_file, number_of_entries):

    # Read the original JSON file

    with open(input_file, 'r') as file:

        data = json.load(file)

    # Extract the first 'number_of_entries' domain knowledges

    extracted_data = data[:number_of_entries]

    # Write the extracted data to a new JSON file

    with open(output_file, 'w') as file:

        json.dump(extracted_data, file, indent=4)

    print(f"{number_of_entries} domain knowledges have been saved to {output_file}")

```

%% Cell type:code id: tags:

``` python

# number of domain knowledges to extract

number_to_extract = 50

# input and output file names

input_filename = '../data/own_data/dialogue_domain_knowledge.json'  # Replace with your actual input file name

output_filename = 'extracted_domain_knowledges.json'

# Run the function

extract_domain_knowledges(input_filename, output_filename, number_to_extract)

```
