Ontology Construction for Eldercare Services with an Agglomerative Hierarchical Clustering Method.

A high-quality ontology for eldercare service can help deliver high quality eldercare services in increasingly aged and digitized societies because it can serve as a reference for formulating eldercare service standards and exchanging information pertain to eldercare services over the Internet. Improving upon previous work, we proposed an agglomerative hierarchical clustering method to construct such an ontology. This method incorporates longitudinal denoising and the word bag model to achieve accurate results verified by experiment results.
