About

Hayato Yamana is a pioneering researcher in distributed information retrieval and web systems, best known for his foundational work on web crawling and large-scale data collection. His most-cited paper, "Experiments of collecting WWW information using distributed WWW robots" (1998, 15 citations), introduced early methodologies for coordinating multiple web crawlers to efficiently gather and index web content—a critical contribution to the emerging field of web search and information retrieval. This work laid the groundwork for modern distributed crawling systems, enabling scalable web archiving and search engine technologies. Yamana’s research spans web science, distributed systems, and data mining, with a focus on improving the efficiency and robustness of web-scale information collection. His experiments demonstrated the feasibility of parallel crawling architectures, influencing subsequent developments in search engine design and web data management. Though his citation count is modest, the conceptual impact of his early work is significant, as it addressed fundamental challenges in web information retrieval during the internet’s formative years. Yamana’s contributions remain relevant for researchers exploring distributed systems, web archiving, and the evolution of search technologies.
