| 中文简介: |  本文描述了词素边界分割算法的两个步骤。任务仅是找到语素条和任何进一步的分析之间的边界，例如可能在语素之间或之内发生的音素删除，插入或替换。这里提出的算法是在不应该利用任何有关其应分析语言的知识的前提下设计的。它也不应该依靠任何人类监督。第一步是使用高精度，低查全率算法找到相对少量的大部分正确的细分，请参阅（Bordag，2005年）。在第二步中，这些分割用于训练分类，然后将其应用于所有单词以在其中找到词素边界。 |
| 课程简介: | This paper describes two steps of a morpheme boundary segmentation algorithm. The task is solely to find boundaries between morphemes bar and any further analysis such as phoneme deletions, insertions or alternations that may occur between or within morphemes. The algorithm presented here was designed under the premise that it is not supposed to utilize any knowledge about the language it should analyse. Neither is it supposed to rely on any kind of human supervision. The first step is to use a high-precision, low-recall algorithm to find a relatively small number of mostly correct segmentations, see (Bordag, 2005). In the second step, these segmentations are used to train a classification, which is then applied to all words to find morpheme boundaries within them. |
