Exploring the Ancient Tamil Text with Python

Tholkaappiyam is the most ancient extant Tamil grammar text and the oldest extant long work of Tamil literature. It is a treasure trove of knowledge for linguists and researchers interested in understanding the structure and rules of the Tamil language. Traditionally, studying Tholkaappiyam required a deep understanding of Tamil and access to specialized resources. However, thanks to the efforts of i18n Solutions Salem, we now have a Python package, aptly named “tholkaappiyam,” that allows us to globalize the ancient text and make it more accessible to people all over the world.

In this article, we will explore the tholkaappiyam Python package and learn how to leverage its features to enhance our NLP projects. But before we dive into the technical details, let’s take a brief look at the history of Tholkaappiyam and its significance.

Understanding Tholkaappiyam

Tholkaappiyam consists of three Adhikaarams, each containing nine Iyals with a specific number of songs or paadal (also known as Sutrās). These songs are classified into categories, making it easier to decipher their core meaning. By studying Tholkaappiyam, we can gain valuable insights into the Tamil language’s grammatical structure and its evolution over centuries.

Getting Started with Tholkaappiyam

To start exploring Tholkaappiyam with Python, we first need to install the tholkaappiyam package. We can do this easily using pip:

pip install tholkaappiyam

Once installed, we can import the package into our Python script using the following code:

from tholkaappiyam import thol

With the package imported, we now have access to various methods and classes to interact with Tholkaappiyam’s data.

Displaying Information

To get an overview of Tholkaappiyam, we can use the following methods provided by the thol object:

# About Tholkaappiyam
thol.about_tholkaappiyam()

# Display Adhikaarams
thol.display_adhikaaram()

# Display Iyals
thol.display_iyal(adhikaaram_no)

# Display Tholkaappiyar
thol.display_tholkaapiyar()

Working with Data

Tholkaappiyam provides access to its entire dataset through the data_json() method. This method returns a JSON dataset containing information about the songs, their meanings, categories, and more.

data = thol.data_json()

To further analyze Tholkaappiyam, the package offers several classes with specific functionalities:

1. Adhikaaram

The Adhikaaram class allows us to retrieve information about a specific Adhikaaram. It has two methods:

• display_total_no_of_songs(): Prints the total number of songs in the Adhikaaram.
• iyals_paadal_count_dict(): Returns a dictionary containing the number of paadals (songs) in each Iyal.

2. Iyal

The Iyal class provides insights into a specific Iyal (chapter). It also has two methods:

• display_total_no_of_songs(): Prints the total number of songs in the Iyal.
• categories_paadal_count_dict(): Returns a dictionary containing the number of paadals (songs) in each category within the Iyal.

3. Paadal

The Paadal class allows us to retrieve information about a specific Paadal (song). It has one important method:

• paadal_data(): Returns a dictionary containing detailed information about the song, such as the paadal’s meaning, category, Iyal, and Adhikaaram.

4. Category

The Category class provides an in-depth analysis of a specific category within an Iyal. It offers two methods:

• paadal_dict(): Returns a dictionary with the category name as the key and a list of songs in that category as the value.
• paadal_data(): Returns a list of dictionaries containing detailed information about each song in the category.

Sample Code Implementations

Let’s take a look at three code implementations that demonstrate the power and versatility of the tholkaappiyam package:

1. Retrieve the number of songs in all the Iyals within an Adhikaaram

n = thol.Adhikaaram(2).iyals_paadal_count_dict()
for i in n:
print(i, '\t\t', n[i])

2. Retrieve the number of songs in all the categories within an Iyal

n = thol.Iyal(1, 3).categories_paadal_count_dict()
for i in n:
print(i, '\t', n[i])

Conclusion

In this article, we have explored the tholkaappiyam Python package, which allows us to understand and analyze the ancient Tamil grammar text, Tholkaappiyam. By leveraging the package’s methods and classes, we can access detailed information about the songs, their meanings, categories, and more. This enables us to enhance our NLP projects by incorporating insights from an ancient and prestigious language like Tamil.

By bridging the gap between ancient texts and modern technologies, the tholkaappiyam package opens up new possibilities for linguistic research, cultural preservation, and beyond. So, let’s dive into the world of Tholkaappiyam and unlock the knowledge preserved within the oldest extant long work of Tamil literature.
