“A 27-year-old PhD scholar finally cracked the riddle which has defeated Sanskrit experts since the 5th Century BC—by decoding a rule taught by “the father of linguistics” Pāṇini.
The discovery makes it possible to ‘derive’ any Sanskrit word—to construct millions of grammatically correct words including ‘mantra’ and ‘guru’—using Pāṇini’s revered ‘language machine’ which is widely considered to be one of the great intellectual achievements in history.
Leading Sanskrit scholars have described the discovery as ‘revolutionary’—and it now means that Pāṇini’s grammar can be taught to computers for the first time...
Pāṇini’s system—4,000 rules detailed in his greatest work, the Aṣṭādhyāyī which is thought to have been written around 500 BC—is meant to work like a machine. Feed in the base and suffix of a word and it should turn them into grammatically correct words and sentences through a step-by-step process.
However, until now, there had been a huge problem. Scientists say that, often, two or more of Pāṇini’s rules are simultaneously applicable at the same step, leaving scholars to agonize over which one to choose...
Thought to have lived in a region in what is now north-west Pakistan and south-east Afghanistan, Pāṇini taught a ‘metarule’ to help decide which rule should be applied in the event of a conflict...
Traditionally, scientists have interpreted Pāṇini’s metarule as meaning: in the event of a conflict between two rules of equal strength, the rule that comes later in the grammar’s serial order wins.
Rajpopat rejects this, arguing instead that Pāṇini meant that between rules applicable to the left and right sides of a word respectively. Pāṇini wanted us to choose the rule applicable to the right side. Employing this interpretation, Rajpopat found Pāṇini’s language machine produced grammatically correct words with almost no exceptions...
“This discovery will revolutionize the study of Sanskrit at a time when interest in the language is on the rise.”
Sanskrit is an ancient and classical Indo-European language from South Asia. It is the sacred language of Hinduism, but also the medium through which much of India’s greatest science, philosophy, poetry, and other secular literature have been communicated for centuries.
While only spoken in India by an estimated 25,000 people today, Sanskrit has influenced many other languages and cultures around the world.
Rajpopat, who was born in Mumbai and learned Sanskrit in high school, explained, “Some of the most ancient wisdom of India has been produced in Sanskrit and we still don’t fully understand what our ancestors achieved.
“I hope this discovery will infuse students in India with confidence, pride, and hope that they too can achieve great things.”
He said that a major implication of his discovery is that now we have the algorithm that runs Pāṇini’s grammar, we could potentially teach this grammar to computers.
“Computer scientists working on Natural language processing gave up on rule-based approaches over 50 years ago. So teaching computers how to combine the speaker’s intention with Pāṇini’s rule-based grammar to produce human speech would be a major milestone in the history of human interaction with machines, as well as in India’s intellectual history.”” -via Good News Network, 12/16/22
