Contractibility for open global constraints

Open forms of global constraints allow the addition of new variables to an argument during the execution of a constraint program. Such forms are needed for difficult constraint programming problems where problem construction and problem solving are interleaved, and fit naturally within constraint logic programming. However, in general, filtering that is sound for a global constraint can be unso...

Contractibility and Contractible Approximations of Soft Global Constraints

We study contractibility and its approximation for two very general classes of soft global constraints. We introduce a general formulation of decomposition-based soft constraints and provide a sufficient condition for contractibility and an approach to approximation. For edit-based soft constraints, we establish that the tightest contractible approximation cannot be expressed in edit-based term...

Open Contractible Global Constraints

Open forms of global constraints allow the addition of new variables to an argument during the execution of a constraint program. Such forms are needed for difficult constraint programming problems where problem construction and problem solving are interleaved. However, in general, filtering that is sound for a global constraint can be unsound when the constraint is open. This paper provides a ...

SOGgy Constraints: Soft Open Global Constraints

We investigate soft open constraints. We generalize and unify classes of soft constraints and adapt them to the open setting. We give sufficient conditions for generalized classes of decomposition-based and edit-based soft constraints to be contractible. Finally, we outline a propagator for an open generalized edit-based soft Regular constraint.

Open Information Extraction with Global Structure Constraints

Extracting entities and their relations from text is an important task for understanding massive text corpora. In this paper, we propose a novel open IE system, called ReMine, which integrates local context signal and global structural signal in a unified framework with distant supervision. The new system can be efficiently applied to different domains as it uses facts from external knowledge b...
