This paper presents the method whereby a language resource package of the Minutes of the National Diet of Japan was constructed for the Full-Text Search System "Himawari" from text data stored in the Full-Text Database System for the Minutes of the Diet and reports the results of the construction. This package includes 11106 minutes (about 450 million characters) of the 1st (1947) to 182nd (2012) plenary sessions and budget committee meetings in the House of Representatives and the House of Councillors. Information related to the meetings, speakers, and the document structures of the minutes are annotated to the minutes in XML to facilitate the analysis of temporal changes in linguistic expressions. In this paper, I first describe the XML tags and an automatic annotation method created using notational clues in the minutes, then I detailed the application of the annotation method to the original minute data to construct the package and summarized the results. Finally, this paper classifies the usefulness of the package by showing how it can be used (a) to extract expressions showing large temporal changes and (b) to investigate the factors of the changes.
