The subject approach to information

The Internet and World Wide Web have made access to information easy but do not solve the problems of finding exactly what is wanted, to the point of overwhelming the reader with information. Since the first edition of this classic librarianship text appeared, the development of computer technology has meant that the organization of information has become a hugely complex area. This fifth edition places emphasis on the intellectual effort required to make meaningful use of the enormous amount of information now accessible to the searcher. Fully revised and updated in comprehensive detail that includes bibliographies, ample examples and quotations, it focuses on: * information retrieval systems * database access systems * online searching and OPACs * hypertext * networked systems. Foskett describes how we search for information by looking at the problems involved, at the theoretical principles suggested as solutions and their practical realization as classification schemes, lists of subject headings and thesauri. Readership: This influential text is widely acknowledged to be essential reading for all students of librarianship and information management, and an invaluable reference tool for practising library and information professionals

From faceted classification to knowledge discovery of semi-structured text records

The maintenance and service records collected and maintained by the aerospace companies are a useful resource to the in-service engineers in providing their ongoing support of their aircrafts. Such records are typically semi-structured and contain useful information such as a description of the issue and references to correspondences and documentation generated during its resolution. The information in the database is frequently retrieved to aid resolution of newly reported issues. At present, engineers may rely on a keyword search in conjunction with a number field filters to retrieve relevant records from the database. It is believed that further values can be realised from the collection of these records for indicating recurrent and systemic issues which may not have been apparent previously. A faceted classification approach was implemented to enhance the retrieval and knowledge discovery from extensive aerospace in-service records. The retrieval mechanism afforded by faceted classification can expedite responses to urgent in-service issues as well as enable knowledge discovery that could potentially lead to root-cause findings and continuous improvement. The approach can be described as a structured text mining involving records preparation, construction of the classification schemes and data mining
