چکیده

Archaeological excavations in the sites of the Indus Valley civilization (2500-1900 BCE) in Pakistan and northwestern India have unearthed a large number of artifacts with inscriptions made up of hundreds of distinct signs. To date, there is no generally accepted decipherment of these sign sequences, and there have been suggestions that the signs could be non-linguistic. Here we apply complex network analysis techniques on the database of available Indus inscriptions, with the aim of detecting patterns indicative of syntactic structure in this sign system. Our results show the presence of regularities, e.g., in the segmentation trees of the sequences, that suggest the existence of a grammar underlying the construction of the sequences.

A Markov Model of the 4500-year-old Indus Script

Although no historical information exists about the Indus civilization (fl. c. 2600-1900 BC), archaeologists have uncovered about 3800 short samples of a script that was used throughout the civilization. The script remains undeciphered, despite a large number of attempts and claimed decipherments over the past 80 years. Here, we propose the use of probabilistic models to analyze the structure o...

Computational Techniques for Inferring the Syntax of Un-deciphered Scripts

Understanding the syntax of an undeciphered writing is a significant challenge. This can provide important clues to the nature of writing and guide potential decipherments. Here we evaluate a set of computational tools that can help us address this problem. We show that significant aspects of the writing can be inferred through this approach without making any assumption about the underlying co...

Statistical Analysis of the Indus Script Using n-Grams

The Indus script is one of the major undeciphered scripts of the ancient world. The small size of the corpus, the absence of bilingual texts, and the lack of definite knowledge of the underlying language has frustrated efforts at decipherment since the discovery of the remains of the Indus civilization. Building on previous statistical approaches, we apply the tools of statistical language proc...
