LNAI conference accepting papers as accompanying proceedings
An idealistic answer would be "It is the contribution that matters, not where it is published." But, of course, it is a thing to worry in our academic world. Usually, LNAI/LNCS proceedings paper would be given more weightage (at least perception-wise) than the papers published in some unknown publishers with ISBN. 

It seems that the conference has two kinds of acceptance: accept for LNAI, accept for ISBN. Based on the quality judgement by the conference panel and the reviewers, the paper is weighted to be published in either LNAI or ISBN proc. What my guess is that the papers which are of good quality (i.e. contribution is significant) would go for LNAI. Good luck!
