This paper explores the frontier of JSiSE research topics. I go over 410 papers of JSiSE journal from Vol. 24 to Vol. 39; I find 1,106 unique paper keywords. Then, I pick up and develop a network of paper keywords and shed light on isolated communities. I introduce 21 isolated communities and their papers. These keywords and papers would reflect the frontier of JSiSE research topics; I hope this paper encourages non-members of JSiSE related to these topics to submit to JSiSE journal.
