First, they only focus on simple context such as word count and co-occurrence in document or sliding window to build word embedding, ignoring latent useful information from selected context. Second, word sense but not word form is supposed to be the minimal semantic unit while most existing works are still for word representation. This paper presents Bilingual Graph-based Semantic Model (BGSM) to alleviate such shortcomings. By means of maximum complete sub-graph (clique) for context selection, BGSM is capable of effectively modeling word sense representation instead of the word form itself. The proposed model is applied to phrase pair translation probability estimation and generation for SMT. The empirical results show that BGSM can enhance SMT both in performance (up to +1.3 BLEU) and efficiency in comparison against existing methods.","doi":null,"url":"https://ijcai.org/proceedings/2016/419","pdf":"https://ijcai.org/proceedings/2016/0419.pdf","markdown":"https://ijcai.org/proceedings/2016/419.md","bibtex":"https://ijcai.org/proceedings/2016/bibtex/419","volume":{"slug":"2016","title":"Proceedings of the Twenty-Fifth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2016","url":"https://ijcai.org/proceedings/2016/","year":2016,"location":"New York, NY, USA","dates":"9–15 July 2016","editors":"Subbarao Kambhampati","isbn":"978-1-57735-770-4; 978-1-57735-771-1","publisher":"AAAI Press / International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":null,"track":"","number":419,"pages":{"first":2950,"last":2955},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
