The collaborating Principal Investigators from the University of Pennsylvania, University of Colorado, University of Washington, and Columbia University are performing preliminary investigations into the feasibility of creating a treebank with multiple representations including both dependency structure and phrase structure.Issues of interest include: * To what extent can the conversion between dependency and phrase structure be automated, and to what extent is hand correction necessary after automatic conversion? * How can we leverage experience from the creation of other treebanks? To address these issues, the collaborating team is convening a working meeting of international scholars who have actively worked on treebanks representing many different formalisms and languages. Building on previous results in the conversion of phrase structure treebanks to dependency structures, tree adjoining grammar structures and combinatory categorical structures, a set of experiments is performed demonstrating the feasibiity of generating phrase structure from dependency structure. This requires well defined phrase structure and dependency structure guidelines for the language in question, currently limited to English. Other languages with tested guidelines for one of the two formalisms include Chinese, Korean, and Arabic (phrase structure) or Czech, German, Dutch, and Russian (dependency structure). The team is extending their conversion experiments to one of these languages as well, creating the necessary additional guidelines in the process. They are sharing a qualitative evaluation of our results with the colleagues at the workshop, and discussing the suitability of further experiments and alternative languages, as input into a resubmission of the CRI proposal.

宾夕法尼亚大学，科罗拉多大学，华盛顿大学和哥伦比亚大学的合作主要研究人员正在对创建具有多种表示的树仓的可行性进行初步调查 *我们如何利用其他Treebanks创建的经验？ 为了解决这些问题，合作团队正在召集一次国际学者的工作会议，这些学者积极从事代表许多不同形式主义和语言的树库。 在以前的结果基础上，将树库的转换为依赖性结构，毗邻语法结构和组合性分类结构的树木，进行了一组实验，证明了从依赖关系结构中生成短语结构的良好性。 这需要针对该语言的定义明确的短语结构和依赖性结构指南，目前仅限于英语。 其他两种形式主义之一的指南的其他语言包括中文，韩语和阿拉伯语（短语结构）或捷克，德语，荷兰语和俄罗斯（依赖性结构）。 团队也将其转化实验扩展到这些语言之一，在此过程中创建了必要的其他准则。 他们正在与研讨会的同事分享对我们结果的定性评估，并讨论了进一步的实验和替代语言的适用性，作为对CRI建议的重新提交的输入。
