She designs a novel MT evaluation metric, YiSi, that uses frame semantics and distributional lexical semantics to evaluate the translation quality of MT output and guide MT systems better at preserving the meaning of the input sentence in translation. In WMT 2018 metrics shared task, YiSi statistical significantly correlates the best with human for evaluating Turkish to-and-from English and English to Russian MT output at system level; and statistically ties for the first place on evaluating Czech to-and-from English, Russian to-and-from English, Turkish to-and-from English, Chinese to-and-from English, English to German, English to Estonian and English to Finnish MT output at sentence level. An YiSi-based semantic textual similarity system is also one of the leading submission in the WMT 2018 parallel corpus filtering shared task. She is also the lead engineer and major author of the NRC&#8217;s winning Russian-English machine translation system in WMT 2017. She was awarded the rising star in the Digital Technologies Research Center of the NRC-CNRC in 2018.<\/p>\n","protected":false},"template":"","meta":{"_relevanssi_hide_post":"","_relevanssi_hide_content":"","_relevanssi_pin_for_all":"","_relevanssi_pin_keywords":"","_relevanssi_unpin_keywords":"","_relevanssi_related_keywords":"","_relevanssi_related_include_ids":"","_relevanssi_related_exclude_ids":"","_relevanssi_related_no_append":"","_relevanssi_related_not_related":"","_relevanssi_related_posts":"","_relevanssi_noindex_reason":"","_mi_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"_links_to":"","_links_to_target":""},"people-type":[523],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v21.2 -
