The comma-free codes and circular codes are two important classes of codes in code theory and in genetics. Fifty years ago before the discovery of the genetic code, a trinucleotide (triletter) comma-free code was proposed for associating the codons of genes with the amino acids of proteins. More recently, in the last ten years, trinucleotide circular codes have been identified statistically in ...

Discourse relation is an important content of discourse semantic analysis, and the study of punctuation is of importance for discourse relation. In this paper, we propose a method of Chinese comma classification based on maximum entropy (ME). This method classifies the sentence relation based on comma with ME by extracting rich linguistic features before and after the commas in sentences. Exper...

We introduce Comma, a methodology for developing cross-organizational business models. Comma gives prime position to patterns of business relationships understood in terms of commitments. In this manner, it contrasts with traditional operational approaches such as RosettaNet that are commonly used in industry. We report the results of a developer study comparing Comma with a methodology recomme...

In is shown explicitly that the Witten's interaction 3-vertex is a solution to the comma overlap equations; hence establishing the equivalence between the conventional and the " comma " formulation of interacting string theory at the level of vertices.

We study how the concept of bounded synchronization delay is related to retrograde comma-free codes. Retrograde codes are a subclass of comma-free codes in which the dictionary of code words excludes not only overlaps of code words but also reversals of overlaps. We give a general upper bound on the maximum size of a retrograde comma-free distionary, provide a construction for a bounded synchro...

Comma placements in Chinese text are relatively arbitrary although there are some syntactic guidelines for them. In this research, we attempt to improve the readability of text by optimizing comma placements through integration of linguistic features of text and gaze features of readers. We design a comma predictor for general Chinese text based on conditional random field models with linguisti...

In this paper we study a generalization of the classical notions of solid codes and comma-free codes: involution solid codes (θ-solid) and involution join codes (θ-join). These notions are motivated by DNA strand design where Watson-Crick complementarity can be formalized as an antimorphic involution. We investigate closure properties of these codes, as well as necessary conditions for θ-solid ...
