MDL-based Acquisition of Substitutability Relationships between Discourse Connectives
نویسنده
چکیده
Knowledge of which lexical items convey the same meaning in a given context is important for many Natural Language Processing tasks. This paper concerns the substitutability of discourse connectives in particular. This paper proposes a datadriven method based on a Minimum Description Length (MDL) criterion for automatically learning substitutability of connectives. The method is shown to outperform two baseline classifiers.

The automatic acquisition of knowledge about discourse connectives
This thesis considers the automatic acquisition of knowledge about discourse connectives. It focuses in particular on their semantic properties, and on the relationships that hold between them. There is a considerable body of theoretical and empirical work on discourse connectives. For example, Knott (1996) motivates a taxonomy of discourse connectives based on relationships between them, such ...
متن کاملModelling the Substitutability of Discourse Connectives
Processing discourse connectives is important for tasks such as discourse parsing and generation. For these tasks, it is useful to know which connectives can signal the same coherence relations. This paper presents experiments into modelling the substitutability of discourse connectives. It shows that substitutability effects distributional similarity. A novel variancebased function for compari...
متن کاملExploring Substitutability through Discourse Adverbials and Multiple Judgments
In his systematic analysis of discourse connectives, Knott (1996) introduced the notion of substitutability and the conditions under which one connective (e.g., when) can substitute for another (e.g., if ) to express the same meaning. Knott only uses examples which he constructed and judged himself. This paper describes a new multi-judgment study on naturally occurring passages, on which substi...
متن کاملImproving the Inference of Implicit Discourse Relations via Classifying Explicit Discourse Connectives
Discourse relation classification is an important component for automatic discourse parsing and natural language understanding. The performance bottleneck of a discourse parser comes from implicit discourse relations, whose discourse connectives are not overtly present. Explicit discourse connectives can potentially be exploited to collect more training data to collect more data and boost the p...
متن کاملThe Effects of Discourse Connectives Prediction on Implicit Discourse Relation Recognition
Implicit discourse relation recognition is difficult due to the absence of explicit discourse connectives between arbitrary spans of text. In this paper, we use language models to predict the discourse connectives between the arguments pair. We present two methods to apply the predicted connectives to implicit discourse relation recognition. One is to use the sense frequency of the specific con...
