1. DARE corpus

The DARE corpus is an annotated data set focusing on pronoun resolution in tutorial dialogue. Although data sets for general purpose anaphora resolution exist, they are not suitable for dialogue based Intelligent Tutoring Systems. The DARE corpus consists of 1,000 annotated pronoun instances collected from conversations between high-school students and the intelligent tutoring system DeepTutor.

2. DT-Grade dataset

The DT-Grade corpus consists of short constructed answers extracted from tutorial dialogues between students and DeepTutor system and annotated for their correctness in the given context and whether the contextual information was useful. The dataset contains 900 answers (of which about 25% required contextual information to properly interpret them).

3. DT-Neg dataset

In this paper, we present DT-Neg corpus (DeepTutor Negation corpus) which contains texts extracted from tutorial dialogues where students interacted with an Intelligent Tutoring System (ITS) to solve conceptual physics problems. The DT-Neg corpus contains annotated negations in student responses with scope and focus marked based on the context of the dialogue. Our dataset contains 1,088 instances and is available for research purposes.
