Abstract
We present a linguistic structure analysis method using a treebank. This method falls under example-based approaches to natural language processing. It, however, analyzes an input sentence by analogy, which is based on a certain relationship among the input and similar sentences in treebank. Our method directly utilizes examples in a treebank, so it is easy to integrate the method with another parsing method and it may be helpful for disambiguation in parsing. In addition, the method goes without any dictionaries, so it can work robustly even if there are some unknown words in input sentences. Some experiments using Penn Treebank shows that correct analyses are produced for about 70% of input sentences, and the analyses similar to the correct ones are generated for other sentences.
