Even though Southeast Asia is one of the most densely populated regions of the world, its rock art is relatively unknown, and the rock art of Micronesia is even less so. As a starting point for comparing Philippine rock art within the region, a systematic quantitative literature review (SQLR) was conducted to assess the current body of accessible publications. The SQLR resulted in 126 viable references, and characteristics of those references were quantified and analyzed to ascertain the qualities of research published to date. The SQLR results show that scholarship in Southeast Asian rock art is increasing and that the research is dominated by Australia-affiliated scholars. It also quantitatively affirmed that the most noted color for rock art in the region is red and the most commonly identified motif is anthropomorphic. Many motifs found elsewhere in Southeast Asia are notably absent in the known corpus of Philippine rock art. Finally, we discuss SQLR methodology and propose integrating collaborative semantic web applications to increase efficiency and relevance.
