Medical Recommendation System using Co-Occurrence Graphs

Abstract

Medical diagnosis [1] is the process of determining which disease explain a person???s symptoms and signs. Correct diagnosis depend on the knowledge and experience of doctors, huge amount of knowledge is distributed in textbooks and documents. it takes a huge amount of time to learn a lot of information for diagnosis, moreover, diagnosis is often challenging, because many signs and symptoms are nonspecific or some symptoms can be many of diseases. Therefor the knowledge processing must be automated. A co-occurrence graph is incorporated from sets of documents that represent knowledge, which is similar to human brain, when people read a book, the book content will become to knowledge. For co-occurrence graph, it created by information extraction from documents, the information that extract from document is read sentence by sentence and words of each sentence will create relation to each other, then the co-occurrence graph will appear and represent to brain knowledge. In this paper will presents an experiment to bring the co-occurrence graph theory to apply with medical information and create the system that contribute the diagnosis from symptoms.
