REVIEW OF LITERATURE
The growth of ICT (Information Communication
Technology) and related application playing major role in business and has open
new interest for researchers. E-Health application has great influence in
medical. E-Health applications assist clinicians in various aspect from
management, reporting and financial outcomes. Decision Support Systems have
been emerged and being increasingly used by many applications, like WebEHR, PMS
and E-Health according to their feasibility in automatically extracting useful
information and predicting and recommending appropriate results to consumers.
Therefore, this research applies a decision support system prototype to enhance
the prediction mechanism for diabetes patients.
Ten-Ho Lin and Von-WunSoo 1 presented
their research by using three datasets, stat-log heart disease, breast cancer
and diabetes and used Minimal Description Length (MDL) principle. They proposed
a greedy search algorithm of the minimum description length to prune the fuzzy
ARTMAP categories one by one. Research
concluded with the experiments that fuzzy ARTMAP pruned have better performance
than MDL principle.
L. Breault 2, worked on Pima Indian Diabetic Dataset (PIDD) publically
available UCI Machine Learning Lab. They find the accuracy of data mining
algorithms using diabetic dataset with 8 variables. 392 cases all non-diabetic
gave the accuracy of 65.1% in prediction. ROSETT a tool used for prediction in
rough sets. The test sets were classified according to defaults of the naïve
Bayes classifier, and the 10 accuracies ranged from 69.6% to 85.5% with a mean
of 73.8% and a 95% CI. Accuracy of predicting diabetic status on the PIDD found
82.6% on the initial random sample, which exceeds the previously used machine
learning algorithms that ranged from 66-81%. Mean accuracy 73.2% found while
executing classifier on 10 random records.
Thus, Chang-Shing Lee, Mei-Hui Wang 3 present five layer
fuzzy diabetes ontology (FDO) for diabetes decisions with semantic decision
support agent (SDSA)that based on knowledge construction mechanism. Proposed
system construct semantic description decision based on fuzzy rules for
diabetes patient. This novel five layer fuzzy ontologies co-related to generate
final description as decision result and cross validated with medical staff.
Buche et al. 4 used rules and ontologies in
relational models and designed query schemes based on fuzzy for heterogeneous
structured, imprecise and incomplete data. Lee et al. 5 summarize news by
using fuzzy ontology. Goncalves et al. 6 proposed inverted hierarchical
neuro-fuzzy BSP system for classification of pattern and extraction of rules in
data. Grelle et al. 7 presented architecture that use agent paradigm powerful
and simple to control the hybrid complex environment. Lee et al. 8 developed meeting scheduling agent based on genetic fuzzy.
However, a better known that vague and imprecise knowledge cannot
produce by the classical ontology in several real world applications. Magni and Bellazzi 9
proposed a model to note variations relation from blood sugar with respect to
time. Quan et al. 10 developed an automatic fuzzy ontology generation
approach for semantic web. Faezeh, Hossien,
Ebrahim 11 presented a technique for clustering (FACT) based on patterns. Automatic
semantic help desk support based on fuzzy ontology proposed by Quan et al. 12.
Leonarda and Antonio 13 used MLP (Multilayer Perceptron)
neural network to detect diabetic by symptoms in retinal images. Network
trained for the optimal global thresh hold that can minimize pixel
classification errors. System performances are evaluated by means of an
adequate index to provide percentage measure in the detection of eye suspect
regions based on neuro fuzzy subsystem. Campos-Delgado et al. 14 Designed and
developed controller that based on fuzzy expert knowledge to circulate blood
glucose level in a body. Yager and Petry 15 presented and approach for
summarization of data using ontologies and proposed a framework that resolves
contradictory evidence for decision making. A query enrichment approach
proposes by Knappe et al. 16. Thus, Cranfield and Pan 17 built relationship
between ontology engineering and model driven architecture. Polat and Gunes 18
used principal component analysis and designed an expert system to diagnose the
diabetes disease in a patient. For instance, Calegari and Farina 19 conducted
scale free analysis with fuzzy ontologies. An intelligent healthcare agent that
uses ontology for respiratory waveform recognition designed by Lee and Wang
mining use techniques and process to examine large scale data collected
periodically. The term also refers to a collection of tools used to perform the
process. Collection of tools available to assist the process of Data mining.
Use of Data Mining application for chronic disease like diabetes is an emerging
research field. Data mining algorithm issued for testing the accuracy in
predicting diabetic status. Diabetic status predicted through Data Mining
algorithms and accuracy can be obtained for validating the results. There is
keen interest in Classification for the researchers of DM and ML. Classification
predict a class that appears in data but not provided in new instance.
Classification train the model on data provided and generated rules and class
relation between the attributes for predication. Algorithm finds relationship
between attribute and co-relate the new instances for predication. At the end a
new instance with same attributes given to algorithm for the prediction of
class that is un-seen in new record, thus algorithm have to predict the class
of coming record as final result.
Radha and Rajagopalan 21 proposed an application based on
fuzzy logic for diagnosis of diabetes. Fuzzy sets and linguistic variable are
used to predict the diabetes in a body. Un-certainty dealt by the mathematical
calculations and with fuzzy logic. Paper also presented with computer based
fuzzy logic with minimum and maximum realtionship values that sepcify fuzzy
frame work. To stong more this relationship fourtypatients data collected for
experiments. Zhou, Purvis and Kasabov 22 presented a technique to select
membership function that based on statistical analysis for fuzzy neural
network. Experiments done on medical data to validate the proposed method. Diabetes
has two main types that is type-1 and type-2 categorize by American Diabetes
Association 23. Type-1 is found mostly in children and young adults, where
type-2 is the most common form of diabetes found in diabetes patients. In
type-2 diabetes patient’s body does not produce enough insulin or produced
insulin does not consumed by the body cells.
Polat et al. 24 worked great to develop a learning system
that diagnose diabetes. Corchado et al. 25 presented an intelligent scheme

37, conducted research and found relation between age groups and activities
of people who are suffering from diabetes disease. They worked to find out
factors that cause individual to be diabetic. Statistics given by the Centers
for Disease Control states that 26.9% of the population affected by diabetes
are people whose age is greater than 65, 11.8% of all men aged 20 years or
older are affected by diabetes and 10.8% of all women aged 20 years or older
are affected by diabetes. The dataset used for modeling and analysis have 50784
total instances with 37 attributes. They computed a new variable age_new as
nominal variable, dividing in to three group’s young age, middle age and old
age and the target variable diabetes_diag_binary is a binary variable. Research
show that 34% of the population whose age is below 20 years were not affected
by diabetes. 33.9% of the population whose age is above 20 and below 45 years
not affected by diabetes. Population whose age greater than 45 were 26.8% and
found not effected by diabetes.
