- Abstract
- Presents a method for the automated analysis and comprehension of foreign affairs news produced by a Chinese news agency. Notes that the development of the method was prededed by a study of the structuring rules of the news. Describes how an abstract of the news story is produced automatically from the analysis. Stresses the main aim of the work which is to use specch act theory to analyse and classify sentences

- Abstract
- Discusses the theory and practice of bibliographic control, provides a definition for a bibliographic centre and for bibliographic control in a national bibliographic centre, and discusses the current situation and future development in bibliographic control in the national bibliographic centre (of China). Makes some suggestions for planning effective bibliographic control in the national bibliographic centre as follows: to collect materials; to recruit advisers; to set up a mission, goals and objectives; to make and implement action plans; to put in place the organizational structure of the bibliographic database; and to make plans for cooperating with other area or national bibliographic centres

- Abstract
- Discusses the theory and practice of subject headings, the principle and application of subject heading lists in various countries, and the present situation of the Chinese subject heading list in Taiwan. Suggests improvements to the chinese Subject Headings as follows: to increase the number of subject headings; to control the vocabulary to be used; to use fixed fields of Chinese MARC, performing the partial function of subdivision in the chinese Subject Headings; to announce the addition, correction and deletion of subject headings regularly and to compile a users' manual; to establish a national subject heading authority file in the MARC format; and to use the Chinese Subject Headings to organize Internet resources

- Abstract
- Since most popular commercialized systems for full text retrieval are designed with full text scaning and Boolean logic query mode, these systems use an oversimplified relationship between the indexing form and the content of document. Reports the use of Singular Value Decomposition (SVD) to develop a Cluster Indexing Model (CIM) based on a Vector Space Model (VSM) in orer to explore the index theory of cluster indexing for chinese full text documents. From a series of experiments, it was found that the indexing performance of CIM is better than traditional VSM, and has almost equivalent effectiveness of the authority control of index terms
