We have search engine study group 2nd at Bunkyo Green Court, Tokyo on 14:00.

Today, Nishida and Hashimto talk about Rast. Rast is initially developed as N-gram based full-text search system, but it has well-desined APIs to segment and to tokenize the source text, so it can be used as N-gram and as Morphological analyzed.

Next, Mori talks about Senna. Senna is full-text search engine to be embedded for DMBS or scripting language. It provides high speed and high accuracy inverted index type engine featured by N-gram index and word index.

We also have talks about OSEKI/Search (search engine that emulates relational database engine/SQL) by Ogoshi, Real-Time Wiki by Eto and Hyper Estraier by Mikio Hirabayashi. We have nice discussions today.

After that, we have a dinner at nearby barbecued chicken restaurant.
