Nowadays, population aging has become a prominent problem all over the world, which brings new challenge to manage multi-type and multi-relation health data from elderly. Existing approaches store those complex data in traditional relational database, which lack support of relation retrieval and is hard to answer elderly's semantic query. In this paper, we design and implement a knowledge graph based question-answer platform (KnowHealth) to manage those health data, which can help the elderly know their health condition better, Specifically, we propose an ontology definition which can describes the entities and relations in aged disease domain. Based on the ontology, we crawl and extract health related information from different input sources. Then, entities and relation extraction methods can be used to construct a knowledge graph. Finally, we completed a historical behavior driven question-answering platform to serve query for elderly. By analyzing and extending intention of questions, answer can be retrieved and reasoned more accurately.
