Agenda7/5/2015DRS 3

DRS (Diabetes recommender system) is a web-based recommendation system for diabetes. It provides diagnosis for diabetes, recommends diabetics drugs, recommends and advice diabetes.1.What is DRS?

7/5/2015DRS 4

DRS is based on Data Mining and Semantic Web techniques provides more accuracy in results.DRS provides more than one service (diabetes diagnosis, drug recommendation, diet recommendation) DRS maintain personalization for users(pateints).Diabetes is one of the most chronic diseases in recent years.The number of drugs increased the number of patients increased.

Data Mining Data Mining Steps

7/5/2015DRS 8

Data Collection & Preprocessing - Diabetes Database from UCI Machine Learning . - It Contains 768 record samples records with 8 attributes (e.g., age, number of pregnant, Plasma Glucose test, etc.) - Pre-processing replacing missing values, convert numeric values to nominal, discretize attributes.Model Building technique - We use decision tree for data mining classification. - we use J48 Classifier for building the model(Implementation of Decision tree).Evaluation & Deployment - Accuracy of the classifier is about 75.78%.

Data Mining Steps7/5/2015DRS 9

J48 Classifier is training and testing the preprocessed diabetics data set. Producing a model in the form of tree and we use this model in our DRS system for Diagnosing new users (diabetic or not)The resulting classification tree model:Classifier Model Building

5. Drugs & Diet Recommendation(Using Semantic Web)7/5/2015DRS 11

Evolving extension of WWW in which web content : - Can be expressed not only in natural language. - But also can be understood, interpreted and used by software agents. - Permitting software agents to find, share and integrate information easily.The idea of having data on the Web - Defined and linked in such a way. - Can be used by machines not only for display purposes, but for automation, integration and reuse of data across various applications

Ontology7/5/2015DRS 13

Why Ontologies are important - Ontological analysis clarifies the structure of knowledge. - Ontologies enable knowledge sharing. Ontology Definition: Formal , explicit specification of a shared conceptualization

Anti-diabetic drugs ontology (an ontology that maintain ant-diabetic drugs).Patient tests ontology ( an ontology that maintain diabetes tests).Diabetes food ontology (an ontology that maintain all foods for diabetics diet). Personal Patient Information ( ontology for patients personal and medical information)DRS Ontologies7/5/2015DRS 17

Define Scope: anti-diabetics drugs ontology for drug recommendation for diabetics Patients in DRS system.Data Gathering & Consider reuse: reusing drugs ontology, collecting data from internet and asking specialists.Enumerate Terms: List all nouns and verbs used in the domain like (drug, drugs classes, drugs names, has consideration, has dose time, etc.)Define Classes: nouns become classes in the ontology.

SWRL Semantic Web Rule LanguageSWRL is a rule language for semantic webAll rules are expressed in terms of OWL concepts (classes, properties, individuals).Rule Example:

We use in writing the diabetes medication rules.

SWRL for Medication Rules7/5/2015DRS 28

We used the SWRL in DRS to represent the relationship between diabetics important tests and suitable drugs. Diabetics medication rules:
