Global Inference for Sentence Compression: An Integer Linear Programming Approach

J. Clarke, M. Lapata
2008 The Journal of Artificial Intelligence Research  
Our work views sentence compression as an optimization problem and uses integer linear programming (ILP) to infer globally optimal compressions in the presence of linguistically motivated constraints.  ...  We show how previous formulations of sentence compression can be recast as ILPs and extend these models with novel global constraints.  ...  Constraints We are now ready to describe our compression-specific constraints.  ...
