Hitachi Ltd has developed a high-speed text retrieval system for the company’s 3050 Unix workstations. The new system is called Bibliotheca/TS (Text Search) and integrates with Hitachi’s new systems concept called Forefront. Bibliotheca has a number of features which are improvements on existing text retrieval systems, including the non-necessity for indexing, the non-occurrence of retrieval noise and suitability for general users since any word can be retrieved. Hitachi says that Bibliotheca is based on Hitachi-developed technology called the hierarchical pre-search method, and homonyms are may be also retrieved. The system uses X Window, and Hitachi’s version of Motif; it also includes an application program interface that enables C language programs to be interfaced with the system. The system is available for client-server systems, or stand-alone. It can also be interfaced with Hitachi’s Hitfile optical filing system, and its Flora word processing hardware Flora. The price of the client system is $3,875 while the server version is $11,627, and both will be available in December.
