LCLR aims to provide a flexible latent structure for increasing the representational power of the model in a useful way, and is demonstrated on tasks and domains where data availability is not a key concern.
• Let {Role(i, j, λ) : λ ∈ L, and 0 ≤ i < j ≤ n} be O(|L|n 2 ) boolean variables such that Role(i, j, λ) = true iff Arg(i, j) is true and takes the role label λ.
