Analysis of the pattern of symbols confirms the linguistic role of ancient signs. The script of the ancient Indus civilization remains undeciphered. The hypothesis that the script encodes language has recently been questioned. Here, we present evidence for the linguistic hypothesis by showing that the script’s conditional entropy is closer to those of natural languages than various types of nonlinguistic systems.

Determining Statistical Signatures for Undeciphered Scripts and Corpora : the case of the Indus Valley Signs
The paper first makes an assessment of a number of arguments about the linguistic or purely semiotic status of the Indus Valley Signs. A ccording to the author it is hard to believe that a wellExpand
Statistical Analysis of the Indus Script Using n-Grams
TLDR
This work forms the basis for the development of a stochastic grammar which may be used to explore the syntax of the Indus script in greater detail and finds that a quadrigram Markov chain saturates information theoretic measures against a held-out corpus. Expand
The “handedness” of language: Directional symmetry breaking of sign usage in words
TLDR
This study shows that the occurrence probability distributions of signs at the left and right ends of words have a distinct heterogeneous nature and uses the existence of this asymmetry to infer the direction of writing in undeciphered inscriptions that agrees with the archaeological evidence. Expand
A Markov model of the Indus script
TLDR
Results indicate that the Indus script exhibits rich synactic structure and the ability to represent diverse content, both of which are suggestive of a linguistic writing system rather than a nonlinguistic symbol system. Expand
On the Brahmi-Indus Connection (a New Passage to Indus Script Decipherment)
The origins of the Indus Valley Civilization are shrouded in mystery. Two significant questions from this unsolved historical problem are the origins of the Brahmi and Indus scripts. In this light,Expand

The script of the Indus valley civilization has defied decipherment. Several attempts have been made in the past to decipher the script but there is no consensus about its content. The lack ofExpand
Computational Techniques for Inferring the Syntax of Un-deciphered Scripts
TLDR
A set of computational tools are evaluated that can help address the problem of understanding the syntax of an undeciphered writing and show that significant aspects of the writing can be inferred through this approach without making any assumption about the underlying content. Expand
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 theExpand
Pictish symbols revealed as a written language through application of Shannon entropy
Many prehistoric societies have left a wealth of inscribed symbols for which the meanings are lost. For example, the Picts, a Scottish, Iron Age culture, left a few hundred stones expertly carvedExpand
