我们的目标是设计一个查询语言的基础上，两个关键字的空间和时间搜索，通过使用一个单一的文本查询在一个直观的方式。这种语言作为一种形式的语法糖可以表达复杂的时空查询，其中包括范围，方向，时间长度和大小的条件，这些条件很难通过传统的基于关键字的搜索系统中的文本查询表示。为了表达这些条件，我们提出的语言引入了12个时空运营商，如算术和方向运营商，使用户能够联合收割机和操纵空间和时间的领域。此外，我们使用“空格字符”（空格键）之间的关键字，用于表示地理距离或时间长度之间的匹配对象在一个直观的方式为一般用户。在本文中，我们提供了一个概述我们提出的搜索系统，我们可以检索地图和Web文档，以突出如何查询语言可以付诸实践，使用复杂的时空查询。最后，我们讨论了用户研究的结果进行评估我们提出的搜索系统的潜在有用性。
Our goal is to design a query language based on two keywords for spatial and temporal search by using a single textual query in an intuitive way. This language as a form of syntactic sugar can express complex spatio-temporal queries which include conditions on range, direction, time length and size which are difficult to express through textual queries in conventional keyword-based search systems. To express these conditions, our proposed language introduces 12 spatio-temporal operators such as arithmetic and directional operators which enables users to combine and manipulate spatial and temporal areas. Also, we use “space characters” (the space-key) between keywords which are used to express the geographical distance or time-length between matching objects in an intuitive way for general users. In this paper, we provide an overview of our proposed search system where we can retrieve maps and web documents to highlight how the query language could be put into practice by using complex spatio-temporal queries. Finally, we discuss the results of a user study carried out to evaluate the potential usefulness of our proposed search system.
