Ayaka Morimoto

Retrieval over Japanese-language corpora, which behaves nothing like the English benchmarks everyone quotes.

The hard parts

Tokenisation, product codes that mix kanji and katakana, and vertical-text scans of manuals written before anyone thought about search. I fine-tune my own rerankers when the general ones give up.

Who hires me

Manufacturers and law firms sitting on decades of internal documents, with a very low tolerance for a confident wrong answer.

Availability

One project at a time. The next slot opens in a few weeks. I also write an occasional newsletter on Japanese RAG evaluation.
