Abstract:
The `Web of Data' is a growing trend for the creation of innovative services on the web. Thus, a search engine for the data is becoming important for promoting data-intensive services. However, full-text search is not suitable for data fragments, and formal query languages are difficult for ordinary users. Therefore, we propose a query answering system in natural language over the `Web of Data'. We focus on mapping of question sentences to open-schema data, and data acquisition, and then propose improvement of accuracy based on user feedback and acquisition of new data by user context information. We also present `Flower Voice', which is an environmental application of the query answering system for assisting with users' fieldwork and confirm the effectiveness.
