This paper presents the syntactic annotation level of a project aimed at providing a small dialog corpus with multiple levels of annotation. The syntactic annotation is based on dependency syntax. We outline the reasons for choosing dependency, and show the syntactic annotation for some constructions. We finish by describing the current state of the project.
Discourse connectives can be analyzed as encoding predicate-argument relations whose arguments derive from the interpretation of discourse units. These arguments can be anaphoric or structural. Although structural arguments can be encoded in a parse tree, anaphoric arguments must be resolved by other means. A study of nine connectives, annotating the(More)
Most approaches to event extraction focus on mentions anchored in verbs. However, many mentions of events surface as noun phrases. Detecting them can increase the recall of event extraction and provide the foundation for detecting relations between events. This paper describes a weakly-supervised method for detecting nominal event mentions that combines(More)
We have argued extensively in prior work that discourse connectives can be analyzed as encoding predicate-argument relations whose arguments derived from the interpretation of discourse units. All adverbial connectives we have analyzed to date have expressed binary relations. But they are special in taking one of their two arguments structurally, and the(More)

Applications for synchronous computer-mediated communication, i.e. chat, like instant messag-ing and chatroom channels, are playing an ever-increasing role in task-oriented (vs. recreational) domains. Information extraction (IE) from chat could provide great value to any process where acting on a real-time information stream is important. However, no(More)
Large scale annotated corpora have played a critical role in speech and natural language research. However, while existing annotated corpora such as the Penn Treebank have been highly successful at the sentence-level, we also need large-scale annotated resources that reliably encode key aspects of discourse. In this paper, we detail (1) our plans for(More)
