| An automated reference librarian is a tool that helps programmers find and use objects in program libraries. Its function is similar to that of a human reference librarian: it is to be an expert at locating information. When a client comes to a human librarian with a request for information the librarian directs the client to the information, perhaps giving instruction on how the materials should be used. In the same way, an automated reference librarian helps a client find and use objects in program libraries. This dissertation develops the structure of an automated reference librarian system that is accessed from program development tools such as text and structure-based editors. The benefits of cooperation and information between a librarian and host system, especially a program knowledgeable host, are explored. One benefit to the user of information sharing is that it allows the librarian to extract information from the host program development tool that the user would otherwise have to supply. The synthesis of reference librarian instances, with emphasis on the use of structured editors as a means for processing librarian source data is also discussed. As a contribution towards the availability of program knowledgeable hosts, an incremental LL(1) parsing algorithm for use in language-based editors is presented. Finally, a working prototype of the librarian system is described. |
