Abstract: We present our approach for constructing a federated searching system for Japanese humanities digital libraries using automatic metadata mapping. We discuss some achievements in the ongoing research to construct a federated searching system. The goals of this system are (1) to perform metadata mapping automatically for Japanese heterogeneous humanities digital libraries and (2) to let users access multiple humanities digital libraries by using only one query input. The proposed automatic metadata mapping method produced the average mapping precision of 94.9%. We also address the metadata-related challenges facing Japanese humanities databases.

Key words: Federated searching system, Metadata mapping, Humanities digital libraries, Universal access
