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 well
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.
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.
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.
On the Brahmi-Indus Connection (a New Passage to Indus Script Decipherment)
TLDR
A omparative feature based study of the Brahmi, Indus and Aramaic scripts is performed, decisively proving that the Brahmis is indeed more closer to the Indus script than to Aramaic.

TLDR
The focus of the study is to identify patterns in the Indus writing and explore its underlying logic without making any assumptions about its content by using various computational techniques including machine learning and data mining.
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.
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 carved
Ancient Greek. His honors thesis in Linguistics, Tongues of Malevolence: A Linguistic Analysis of Constructed Fictional Languages with Emphasis on Languages
TLDR
New method of investigating an undeciphered writing system using a computer, by analyzing the written images as images instead of relying on a transcription scheme to map written characters to numbers, yields findings that support Serafini's recent statements that the writing is artistic, not linguistic.
Corpora of Non-Linguistic Symbol Systems
TLDR
The popular press has promoted recent claims of statistical methods that can distinguish writing from non-linguistic symbols, so this project fills that void by developing electronic corpora of known non-lingsuistic systems.
