The publication of a paper means that the paper is published in a journal and retrieved by the corresponding retrieval tools, which is the real publication, and it is also true for sci papers, so strictly speaking, publication includes inclusion, because inclusion is the standard of successful publication, but if publication only refers to a journal, then publication and inclusion are parallel. Publication, inclusion and successful publication are isomorphic. An article can only be included after publication, but it is impossible to be included after publication.
