According to The Triangle of Reference, words/symbols are endowed with references, some of which are oneon-one connected, and some of which are one-on-multiple colligated, modulated by social convention. Phenomena of using homonym are ubiquitous while the system of using it is still opaque. The multiple meaning of homonym is considered to have a pragmatic mechanism in which the implementing process of utterer and the construing pattern of hearer are regulated and formulated. This paper is tentatively cogitating polysemy in a system of pragmatic utility and tabling a pragmatic mechanism of homonym for better understanding and academic contribution of it.展开更多

However, its actual impact is significantly influenced by the semantic ambiguity problem of tags. So, in this paper, we proposed a novel way of detecting homonyms, one of the main sources of tag＇s semantic ambiguity problem, in noisy folksonomies. The study is based on two hypotheses： 1） Users having different interests tend to have different understanding of the same tag. 2） Users having similar interest tend to have common understanding of the same tag. Therefore, we firstly discover user communities according to users＇ interests. Then, tag contexts are discovered in subsets of folksonomy on the basis of user communities. The experimental results show that our method is effective and outperform the method finding tag contexts using all tags in folksonomy with overlapping clustering algorithm especially when various users having different interests are contained by the folksonomyo展开更多
