  ◆◆◆ AI Projects & Research◆◆◆• Developed a multi-label model for product reviews that outperformed company’s labeling system by improving accuracy by 20% and reducing cost by 50%.• Developed a Simplified to Traditional Chinese conversion model that improved the sentence-level accuracy by 10% compared with company’s API and opencc.• Modified and re-trained the Chinese spellcheck language model proposed by ByteDance [arXiv:2005.07421] and outperformed the paper's result (Detection-level and Correction-level f1 scores reach 74.6 and 70.2 on SIGHAN 2015 test set). Which can be used to correct typos (e.g. OCR, ASR).• Designed an attention-based explainable model for classification/multi-label problems that can return both labels and corresponding keywords in real-time.◆◆◆ Business Support ◆◆◆• Deployed an information extraction API for policy documents and provides long-term data delivery for the insurance group company.• Developed a generalized tabular extraction API for pdf documents. User can access specific tables by input keywords.• Created interactive websites of AI projects for business introductions and demonstrations.• Support 3+ customer POC projects per month.◆◆◆ Invention Patent ◆◆◆*Domain words extraction algorithm*Domain words extraction algorithm is a semi-supervised method by giving several known domain words then return related words from documents. For example, give the words “fever” and “cough” then the algorithm will return “runny nose”, “sore throat” and other related words from given documents.• Redesigned and optimized the algorithm that improved NDCG score by 50% and the runtime was 3 times faster. • Extended the feature of algorithm that can apply to multilingual documents/corpus.
