Linguistic form and meaning in a computational analysis of learner language -- On the integration of morpho-syntactic and semantic analysis

本研究项目探索和开发了一种新的计算体系结构，用于分析学习者的语言，特别是第二语言学习者的语言写作。我们的目标是将形式和意义的分析结合起来，使形态句法分析能够在学习者完成给定语言学习任务所需表达的意义的信息的基础上提供信息。该模块结构将冲突信息的反向通道与高效的搜索策略相结合，使其能够通过在所有处理级别获得的信息来影响同形句法分析。在计算语义学的传统中，推演推理和演绎推理的整合在系统中扮演着重要的角色。新的整合分析架构的成功可以基于来自德语阅读理解练习语料库(CREG)的教师注释的学习者答案来评估。新的整合方法对于学习者语言的形式和意义的分析具有广泛的相关性，例如智能语言教学系统的反馈的生成，语言测试中的语言水平的自动评估，或者学习者语料库的注释为语言发展提供信息。在更广泛的影响方面，该项目解决了如何利用自然语言话语的语言或超语言语境来分析和解释自然语言话语的一般问题。

This research project explores and develops a new computationalarchitecture for analyzing learner language, specifically the languagewritten by second language learners of German. The goal is tointegrate the analysis of form and meaning in a way that makes itpossible to inform the morpho-syntactic analysis on the basis ofinformation about the meaning that the learner needs to express inorder to complete a given language learning task. The modulararchitecture combines backchannels for conflict information withefficient search strategies to make it possible to influence themorpho-syntactic analysis through information obtained at all levelsof processing. The integration of abductive and deductive reasoningcomponents in the tradition of computational semantics plays aprominent role in the system.The success of the new integrated analysis architecture can thoroughlybe evaluated on the basis of the teacher-annotated learner answersfrom the Corpus of Reading Comprehension Exercises in German (CREG).The new integrated approach to the analysis of the form and meaning oflearner language is of relevance in a wide range of contexts, such asthe generation of feedback for intelligent language tutoring systems,the automatic assessment of language proficiency in language testing,or the annotation of learner corpora informing linguistic researchinto language development. In terms of broader impact, the projectthus addresses the general question how the linguistic orextra-linguistic context of natural language utterances can be usedfor their analysis and interpretation.
