Worked on Japanese OCR data annotation and processing using Google Vision OCR integrated with annotation workflows. Built an OCR pipeline to extract Japanese text from images such as invoices, documents, and signboards. Processed and cleaned OCR output, then performed bounding box annotation and text labeling using Label Studio. Applied Named Entity Recognition (NER) to structure extracted data (e.g., names, dates, amounts). Improved OCR accuracy by validating and correcting extracted text during annotation. Prepared high-quality labeled datasets for training and improving AI/ML models.
