In Situ Answer Sentence Selection at Web-scale
Zeyu Zhang, Thuy Vu, Alessandro Moschitti
Current answer sentence selection (AS2) applied in open-domain question answering (ODQA) selects answers by ranking a large set of possible candidates, i.e., sentences, extracted f…
Double Retrieval and Ranking for Accurate Question Answering
Zeyu Zhang, Thuy Vu, Alessandro Moschitti
Recent work has shown that an answer verification step introduced in Transformer-based answer selection models can significantly improve the state of the art in Question Answering.…
Lasserre Integrality Gaps for Graph Spanners and Related Problems
Michael Dinitz, Yasamin Nazari, Zeyu Zhang
There has been significant recent progress on algorithms for approximating graph spanners, i.e., algorithms which approximate the best spanner for a given input graph. Essentially…
Characterizing Demand Graphs for (Fixed-Parameter) Shallow-Light Steiner Network
Amy Babay, Michael Dinitz, Zeyu Zhang
We consider the Shallow-Light Steiner Network problem from a fixed-parameter perspective. Given a graph , a distance bound , and pairs of vertices $(s_1,t_1),\cdots,(s_p,…
