ABSTRACT Information requirement elicitation (IRE) is essential in wireless Web service to elicit information requirements through interactive choice prompts. We present a high-level user interface for an IRE-enabled information system, in the context of database queries by a mobile Web user. The prototype is based on the notion of a query-by-object (QBO) approach of building a query using multiple user-level steps. The test prototype system uses the mobile information devices profile (MIDP) of the Java 2 Platform, Micro Edition (J2ME), for a wireless front end, and a Java 2 Platform, Enterprise Edition (J2EE) application server and an object-relational database management system (ORDBMS) at the back end. A sample set of dynamic queries demonstrates ease of use by the users.

    ABSTRACT: Nowadays, two of the main challenges involving spatio-temporal databases concern the integration of their spatial and temporal features to store and query spatial objects changing over time, and the development of a simple and friendly language to query spatio-temporal data. In this paper we gather these two challenges by proposing Moving GeoPQL, a language defined in order to express spatio-temporal queries, extending the Geographical Pictorial Query language (GeoPQL). The proposed evolution is based on the concept of temporal layer that allows specifying the spatial configuration of moving objects in a time interval. More layers allow representing changes in terms of spatial configurations. Some examples of query formulation and system operation are described in the article. Finally, an experiment has been carried out for evaluating the usability of the Moving GeoPQL system. Results of this experiment showed that it facilitates the spatio-temporal query formulation since it is more user-friendly and ease to use compared to textual query languages.

    ABSTRACT: An advanced search interface for mobile devices is presented. The search interface employs the query-by-object (QBO) approach which enables end users to obtain information in a database without using SQL. So far, the QBO approach has been employed in a number of applications. The aim of this research is to develop a visual user interface on mobile devices so that the users can more intuitively manipulate the objects for information retrieval. In this paper, the user interface, an algorithm of SQL generation, and the system architecture are presented. A framework to generalize the QBO approach with the interface for different databases is also considered.

    ABSTRACT: This paper presents an advanced search system which enables end users to search for information stored in an e-learning system. Records in a database deployed in the e-learning system are mapped to the learning objects, which include problems, users, submission records, accepted solutions, contests (exercises), problem setters, and so on. The system employs a query-by-object (QBO) approach, where users do not need special knowledge of conventional SQL query writing. This paper presents a general overview of the e-learning system as well as the QBO approach for the system and its system architecture. Demonstration of the system and its usability are also discussed.
