在目前汉语文献信息前处理技术中仍主要采用人工标引，由于其效率低，标引结果不一致，严重影响了信息的快速传递和信息资源的共享，与目前科技迅猛发展的形势极不适应。近几年虽然也在开发各种自动标引技术，但真正付诸实用并准确可靠的尚不多。在此，我们介绍新开发的两种自 Due to its low efficiency and inconsistent indexing results, the manual transmission of Chinese literature information preprocessing technology is still mainly used, which has seriously affected the rapid transmission of information and the sharing of information resources, which is incompatible with the current rapid development of science and technology. Although in recent years a variety of automatic indexing technologies are being developed, few are actually put into practical use and are accurate and reliable. Here, we introduce two newly developed self
