This paper describes an annotation guideline for a temporal relation-tagged corpus of Chinese. Our goal is construction of corpora to be used for a corpus-based analysis of temporal relations among events. Since annotating all combinations of events is inefficient, we examine the use of dependency structure to efficiently recognize temporal relations. We annotate a part of Treebank based on our guidelines. Then, we survey a small tagged data set to investigate the coverage of our method. While we find that use of dependency structure drastically reduces manual effort in constructing a tagged corpus with temporal relations, the coverage of the methods achieves about 63%.
