Machine Learning and NLP-Based Approach for Constraint Acquisition Problems

A. Bahafid, Z. Erraji, N. Abdou Mohamed, A. Allak, K. Gaanoun, I. Benelallam

Systems Modelling and Simulation · Springer Nature Singapore · pp. 146–158

ⴰⴳⵣⵣⵓⵍ (ⵙ ⵜⵏⴳⵍⵉⵣⵜ)

Integrates Natural Language Processing with constraint acquisition through a conversational agent, so novice users can describe NP-complete problems — planning, scheduling, resource optimization — in natural language. The system interprets the description, formulates it as a constraint network, solves it, and presents alternate solutions when available.
