Retrieval Assistance Mediated by Conceptual Views and Multiplex Searching

9215085马库斯，这是一个为期三年的奖项的第三年，该奖项旨在调查对经验不足的搜索人员以及专家搜索人员来说，使搜索过程更容易和更有效的高潜力技术。一种实验搜索辅助方法通过以下方式增强以获得更大的有效性：1)用面向图形的用户界面(GUI)替换面向文本的用户界面，以及2)扩展基础搜索模型以用作在具有口头索引字符的通用数据库以及在书目数据库中进行搜索的辅助基础。增强型系统在各种实验用户上进行了测试，以通过封装用户问题的概念表示和指导生成、执行、评估和修改促进高效和有效搜索所需的多路搜索策略来确定图形用户界面对用户的帮助程度。这些测试比较了书目和全文以及其他非书目数据库的结果，以及不同形式的用户界面的结果，从高度用户导向的互动到高度自动化或系统导向的模式，在这些模式下，用户倡议可能仅限于对检索到的文件的初始问题陈述和最少量的相关反馈。

9215085 Marcus This is the third year of a three-year award to investigate techniques of high potential for making the search process easier and more effective for inexperienced as well as expert searchers. An experimental search assistance method is enhanced for greater effectiveness by: 1) replacing the textually oriented user interface with a graphically oriented user interface (GUI), and 2) extending the underlying search models to serve as a basis for assistance for searching in general databases with a verbal indexing character as well as in bibliographic databases. The enhanced system is tested on a variety of experimental users to determine how well the GUI aids the user by encapsulating the conceptual representation of the user's problem and guide in the generation, execution, evaluation, and modification of the multiplex search strategies needed to facilitate efficient and effective searching. The tests compare results from bibliographic and full text, and other non-bibliographic databases, as well as for different modalities of user interfaces, ranging from highly user-directed interactions to highly automated or system-directed modes, where user initiatives may be limited to an initial problem statement and a minimal amount of relevance feedback on retrieved documents.
