Abstract: This paper introduces the design and implementation of a literature metadata search and sharing system, based on meta-search and Web information extraction technology. The system provides users a unified retrieval interface to search and view the meta-data, which is collected from multiple sources and sorted in relevance. Furthermore, the system is a literature metadata sharing and discussion platform to facilitate the communication and collaboration between the researchers. Experimental results show that the system has better query performance, which can improve the efficiency of scientific research.

Key words: meta-search, information extraction, metadata, data sharing
