什么是自然语言处理中的chunker? [英] What is a chunker in Natural Language Processing?

问题描述

有谁知道在文本处理的上下文中什么是chunker以及它的用途是什么?

Does anyone know what is a chunker in the context of text processing and what is it's usage?

推荐答案

根据这些幻灯片，分块是解析的替代方法，它提供了一个句子的部分句法结构，具有有限的树深度，而不是完整的解析.

According to these slides, chunking is an alternative to parsing that provides a partial syntactic structure of a sentence, with a limited tree depth, as opposed to full on parsing.

它比完整解析更有限，但在提取或忽略信息时就足够了，因此被多次使用，因为它比解析更快、更健壮.

It is more limited than full parsing, but is sufficient when it comes to extracting or ignoring information, and is thus many times used, as it's faster and more robust than parsing.

幻灯片中提供了更多信息.

Much more information is available in the slides.
