The Method Of Classification And Similarity Calculation For Mobile Health Questions Based On The Field Dictionary

With the open of 4G era, the development of Mobile Internet becomes faster and faster and the areas it permeates become wider and wider. Mobile health was born with the combination of Mobile Internet and medical treatment which has rapidly developed with Mobile Internet and Correspondingly it leads to the emergence of Q &A platform for mobile health. Patients can consult a doctor anytime, anywhere or get medication recommendations through the platform. When the quantity of questions raised by users become larger and larger over time,the platform can classify these questions to bring a better browsing experience. The user can get answer faster through the similar questions with the questions user submit returned by the platform.The main work is as follows:1.Proposed a method of classification based on field dictionary for Mobile Health questions and classification model combined with field dictionary. Segmenting words for questions combined with the field dictionary before classification, and at the same time,the answers to questions added to enrich the feature words, Adding weight to feature words with a category distinction.2.Proposed a semantic-based similarity keywords- questions index model,which can match keywords or similar words of the target question(to be calculated similarity questions) to find the questions containing the target keywords or similar words. These questions will be saved to a collection for further processing.3.Proposed a method of similarity calculation based on the field dictionary for Mobile Health questions.Adding weight to field words in target questions to bring a higher scores of similarity calculation,reducing the impact of non-field words in similarity calculation.So that similarity score can be more reasonable when sorting results.4.The related technologies of this study have been applied to Yun Ban health management platform based on the real data from the platform to meet the needs ofThe method of classification and similarity calculation for mobile health questionsbased on the field dictionary platform on classification and calculation of similar questions. The effectiveness of applying these methods to the platform has been verified by experiment.
