“…To clearly identify the process of the ontology development to represent the information in user context, this section (section II) is mainly organized in six (6) categories such as users' information needs, users' information needs in context, representation of contextualized information, generalizing design approach, and validation and evaluation process. The framework we identified to maintain the ontology for our application is described separately in section III.…”

“…Some examples are given in Table I. In this study we identified that, farm environment, types of farmers, farmers' preferences, and farming stages (considered as the user context model) are the important factors that need to be considered when delivering agricultural information and knowledge to farmers [6].…”

“…users' context model). Since the farmers are the main stakeholders in the agriculture community and other stakeholders are willing to help farmers in various manners, we have identified the users' context specific to the farmers in Sri Lanka such as farm environment, types of farmers, farmers' preferences, and farming stages [6]. The farming stages that we have identified as relating to our application are Crop Selection, Pre-Sowing, Growing, Harvesting, PostHarvesting, and Selling [6].…”

Abstract-The Agriculture sector plays a vital role in Sri Lanka's economy. Not having an agricultural knowledge repository that can be easily accessed by people in agriculture community in Sri Lanka within their own context, is a major problem. As a solution, a large user centred ontology for Sri Lankan farmers was developed to provide required information/knowledge not only in a structured and complete way, but also in a context-specific manner. Since this problem is not only limited to farmers, we extend this for every one working in the agriculture domain. We validate the ontology in terms of accuracy and quality. The online knowledge base based on the ontology with a SPARQL endpoint was created to share and reuse the domain knowledge that can be queried based on user context. A Mobile based application and a Web based application were developed to provide information/knowledge by using this ontology. These applications are also used to evaluate the ontology by getting the feedbacks from users to the knowledge in the ontology. It is very difficult to maintain a large complex ontology. To maintain our ontology, we identified various processes that are required to develop and maintain ontology as a collaborative process. A semi-automatic end-toend ontology management system was developed to manage the developed ontology and the knowledge base. It provides the facilities to reuse, share, modify, extendand prune the ontology components as required. The facilities to capture users' information needs and search domain information in user context are also included. In this paper, we present a summary of the overall development process of the ontology including the end-to-end ontology management system.

Abstract-Tourism industry plays a crucial role in the economics growth in countries of South East Asia and hence the demand for rich local tourist information for visitors. In these countries, there are unique deciding impact factors to visitor journey such as constraints in culture, laws, and festivals. Such special information has not been available or implemented in general search engines so far. In this paper, we design an ontology for Thai travel industry to support an intelligent finding of these local events and their constraints using semantic web. The primary contribution of this paper is a new approach to design ontology for Thailand travel industry on both general information and specific dynamic local information using Domain Ontology Graph (DOG) and location based services. As a result, this ontology design will be applied to an intelligent searching for making decision of tourists. This ontology design will be used in semantic tourism applications in the future.Index Terms-Location-based service, ontology, semantic tourism, semantic web, travel ontology.
