<p>I tried .txt of each files in CHISE IDS (<a href="https://www.chise.org/ids/" rel="nofollow noreferrer">https://www.chise.org/ids/</a>) but it seems that most of the components are not normalized. Is there any work that has normalized the characters in IDS?</p>

what do you mean by normalized? for example the component version of 火 could be 灬 or 火-- with both being equally common.  Also many components are made up of other components, while still being components themselves.  If you explain what you mean by normalized we can better help with what you need.

Is there a list of normalized character decomposition ( to 足, 龰 to 止, etc.)?
