We are making steady progress on our websites. The semdom.org website has now gone live. It used to be embedded in this site, but has now been separated for several reasons. Not everyone who uses Ron Moe's semantic domain model are interested in Rapid Word Collection and the site would be more useful if it were directly accessible, rather than a submenu of this site. Secondly, as the semantic domain model changes, we want to have a permanent record of the domains and where they get moved to between versions. Now, with the acquisition of semdom.org, the URI for each domains will be constant, and migrating systems from one version to another of the Semantic Domains will be easier.
The domain for words describing happiness are found here in version 4 of the Semantic Domains:
Any program that uses the domains can reference this uri which also includes the version of the domains. Previously, software used in word collection would only reference the specific domain number: 18.104.22.168 without specifying which version of the domains.
Anyway, try out the domain search on semdom.org. It is fun to use!
