| 中文摘要: |
| 本文给出了一个不删词的命名游戏模型，说话者根据自身词库中词的使用权重选词，听者所听到的词与自身词库中的词对照，若词库中已有该词，则将该词的使用频数增加，否则将所听到的词加到自身词库中。讨论个体有序词库词的使用强度在前三名的词的变化规律，结果表明，每个个体的使用强度在前三名的词中，至少有一个词是所有个体共有的，并且排名前三位的其他词也是使用频数较高的，这为现实中，同一个物品往往有不同命名的现象提供了一种形成机制。在此基础上，我们讨论了收敛时间问题。 |
| 英文摘要: |
| We present a new naming game model here, which do not include a deleting-word process. In this model, a word is selected out by one speaker with independent possibility according to its weight in the speaker’s dictionary. Then the listener compares the given word with words in his own dictionary. If the word already existed in the dictionary, add one weighting point to it. If not, put the word in his dictionary as a new item. Then we investigate the variation dynamics of the frequency top three words in the self-order dictionary. The result shows that in most cases there’s at least one word in the frequency top three words of the individual’s dictionary is shared by all the other dictionaries. Also, an individual’s frequency top three words always own high weight in other dictionaries. We believe our study could provide a formation mechanism to explain why an object would probably have different names. In addition, the convergence of time in this model is also discussed. |
