コンピューターを用いた簡易な質疑応答検索システムの構築と評価

Abstract

Kanto Teishin Hospital's drug information division has had a considerable amount of its time taken up by answering patients and doctors questions. A Q & A search was established with the objective of reusing past Q & A information, reducing the answer time, and also for unifying the answer content. An evaluation of performance was also undertaken.An NEC 9821-BP, running database software, Kiri version 5.02, was utilized with a system containing a main menu of five headings: Search, Additional Input, Print List and Exit. Five types of searches were included. A secondary search, for adding additional conditions, appeared after the first. The search results and database input screens were identical, and are set to display data in a card-like form. Information for the system included Q & A data from January 1992 to June 1995.For the evaluation, twenty-six subjects' search times, and six subjects' data processing times, were measured with a stopwatch (along with a quality check of the processed information). All subjects were also given a questionnaire regarding the system's usability.As a result, whether or not the subject had any experience in such information oriented fields like DI, was found to be a statistically significant factor affecting the search. However, in searches between certain jobs or hospitals, no adverse effect was statistically possible. A quality check revealed a 70% compatibility with the systemindexing, while among experienced processors, this rate was 90.7%. One key word mentioned was “high search efficiency” . this system was thus found to be useful in a medical context and, in the future, the probability of utilizationboth with in, and between hospitals is high.
