Abstract

Automated Information Retrieval describes a fully automated Boolean System and gives special attention to theoretical problems in automatic retrieval of textual information. The book details algorithms in each process in the system, including those that are radically new in the retrieval process and those that are adaptable to the individual. New approaches to evaluating information retrieval systems and studying their performance are included. This book reviews the general principles of constructing any system, such as an information retrieval system. It provides a detailed analysis of basic concepts such as information need, information, information crisis, and the notation of information retrieval. It examines the goal, function, structure, and language of an information retrieval system. It describes the construction of an information retrieval system (methods, algorithms, and approaches). It details different approaches to evaluating the results of information retrieval. It features new directions in the development of information retrieval systems.

Abstract

Demand for the conservation of rapidly disappearing plants and ecological communities has provided botanists, systematists, and computer scientists with a unified goal--the production of a computer-based information checklist for all of the world's plants. Progress has been rapid in recent years. From a diverse array of disconnected systems and databases, there now exists a single, internationally supervised organization that is working to create an Internet accessible "common directory" of existing databases and a computer-based vascular plants action list. This book details the proceedings of that organization's symposium which examined the wide range of options open to the biodiversity community in creating a global plant species information system. Questions addressed include how an effective single taxonomic catalog and reference system can be conceived and implemented; what computer system, software, and data structures might enable both contributions from many sites and global access to the information; and how the needs of the biodiversity, conservation, pharmaceutical, agrochemical, biotechnology, and plant breeding communities can be met by using the plant catalog as a backbone for a variety of other databases of applied botanical data. This volume will be welcomed by all those in the fields of biodiversity and conservation who want to follow the details of this stimulating and important endeavor.
