In this paper, after a brief review of current computational models on language emergence, a multi-agent model is introduced to simulate the emergence of a compositional language from a holistic signaling system, through iterative interactions among heterogeneous agents. A coevolution of lexicon and syntax (in the form of simple word order) is tracked during communications with indirect meaning transference, in which the listener's comprehension is based on interactions of linguistic and nonlinguistic information, and the feedback is not a direct meaning check. In this model, homonymous and synonymous rules emerge inevitably, and a sufficiently developed communication system is available only when a homonym-avoidance mechanism is adopted. In addition, certain degrees of heterogeneity regarding agent's natural characteristics and linguistic behaviors do not significantly affect language emergence. Finally, based on theories of complex networks, a preliminary study of social structure's influence on language emergence is given, and a coevolution of the emergence of language and that of simple social structure is implemented.

Basic Words and Language EvolutionPDF
Language and linguistics 5(3):643-662, 2004
In this paper, the basic words introduced by Swadesh(1952,1955) are used to uncover information about language evolution. In section 2, based on Chen (1996), Swadesh's 200-word list can be split into two sub-groups; the first 100 words, called high rank, are more stable and ...MORE ⇓
In this paper, the basic words introduced by Swadesh(1952,1955) are used to uncover information about language evolution. In section 2, based on Chen (1996), Swadesh's 200-word list can be split into two sub-groups; the first 100 words, called high rank, are more stable and loan-resistant than the second 100, called low rank. More retentions tend to be present among the high rank words while borrowed elements tend to occur more frequently among the low rank words. This feature can be used to distinguish retentions and borrowings when the evolution of a language has been blurred by language contact, such as the transmission of Middle Chinese entering tones into Pekinese. In section 3, we argue that Swadesh (1955)'s 100 basic words (high rank) are better for sub-grouping Chinese dialects, compared with Dolgopolsky (1964)'s 15-word list and Yakhontov' 35-word list.
