Submodular Function

We treat the text summarization problem as maximizing a submodular function under a budget constraint. We show, both theoretically and empirically, a modified greedy algorithm can efficiently solve the budgeted …...

We present a submodular function-based framework for query-focused opinion summarization. Within our framework, relevance ordering produced by a statistical ranker, and information coverage with respect to topic distribution and diverse …...

In this study, we consider a summariza- tion method using the document level sim- ilarity based on embeddings, or distributed representations of words, where we as- sume that an embedding …...
