This paper introduces an infrastructure for the analysis of legal metadata and textual data on international investment and trade disputes. The developed database architecture consists of three main components: (1) a WebCrawler of two key web sites for international economic law dispute information; (2) a document analyzer to transform PDFs into text files, identifying structure and footnotes within document, finding references to other disputes and storing texts as XML; and (3) multiple user interfaces to allow different user types to access the data. The architecture allows users to launch metadata queries and/or to investigate textual corpora. It therefore provides a versatile new framework for international economic law research from various angles and disciplines.
