Objective function: We aim to maximize: where Φ prosody is the scores based on semantic prosody, Φ coord captures the distributional similarity over coordination, and Φ neu controls the sensitivity of connotation detection between positive (negative) and neutral.
soft constraints (edge weights): The weights in the objective function are set as follows: Note that the same w coord (a 1 , a 2 ) has been used in graph propagation described in section 2.2. α controls the sensitivity of connotation detection such that higher value of α will promote neutral connotation over polar ones.
