An Ontology-Based Query Manager: Usability Evaluation
نویسندگان
چکیده
In this paper, we describe the usability evaluation experiments of an ontology-based Query manager, which is part of the SEWASIE system (SEmantic Webs and AgentS in Integrated Economies). The usability evaluation is an important step of the User-Centered Design Methodology, followed to develop the entire project that aims at enabling a uniform access to heterogeneous data sources through an integrated ontology. The Query Manager allows the user to construct the query by a diagrammatic interface generating precise and unambiguous query expressions. The main goal of our experiment is to demonstrate the ease of use of the Query Manager independently of the domain user expertise. This study confirms that the Query Manager is usable as for the endusers (domain-expert users) as for the non-domain expert users.

Query Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملOntology-Based Natural Language Query Processing for the Biological Domain
This paper describes a natural language query engine that enables users to search for entities, relationships, and events that are extracted from biological literature. The query interpretation is guided by a domain ontology, which provides a mapping between linguistic structures and domain conceptual relations. We focus on the usability of the natural language interface to users who are used t...
