Optimizing Efficiency-Effectiveness Tradeoff of Probabilistic Structured Queries for Cross-Language Information Retrieval

Probabilistic Structured Queries (PSQ) is an efficient cross-language information retrieval (CLIR) method that can be used as the first stage in a cascaded neural CLIR system. The effectiveness and efficiency of PSQ depend on how translation probabilities are pruned, which has not been fully explored in prior work.
