Project Description

The Ogawa Corpus contains diary data collected by the generative linguist Yoshiki Ogawa. Ogawa has taught at Graduate School of Information Sciences, Tohoku University, since 2004. He has published a great number of books and articles mainly on syntax, morphology, lexical semantics, and diachronic change in morphosyntax. The release of this set of data is part of the many research activities driven by the Research Unit on Language Change and Language Variation, led by Yoshiki Ogawa.

He observed his first-born daughter Ayumi from birth (04-JUL-2011) until 6;2, as she was growing up in Miyagi. The data is based on handwritten records collected virtually daily (2250 days over 6 years and 2 months), although her first utterance is at 0;9 and there are few utterances in her first two years. The data contains 22,671 utterances by Ayumi, without including almost any utterances by other speakers (mainly, her mother and father). A comment is provided for some utterances, establishing the context and interpreting the child's utterance.

He has also been observing his second-born daughter Mari from birth (2015, October 6th) until the age of 4-year-and-2-month and is planning to observe her until the age of 7-year-old, as she is growing up in Miyagi. The data is based on handwritten records collected virtually daily (1524 days over 4 years and 2 months, as of December 6th, 2019), although her first utterance is in her 4 months old and there are few utterances in her first two years. The data contains 12995 utterances by Mari (until her 4 years and 2 months), without including almost any utterances by other speakers (mainly, her mother and father). A comment is provided for some utterances, establishing the context and interpreting the child's utterance.

An electronic version of this data was adjusted to CHAT format and provided with morpheme coding (JMOR07) by Susanne Miyata (Aichi Shukutoku University).
