Probabilistic-Record-Linkage-MatLab

A probabilistic approach to record linkage using Fellegi-Sunter framework with difference matrix .

A probabilistic approach to record linkage using Fellegi-Sunter framework using MatLab . It can be used with any versions of MatLab . Functions are :

readfile % Read any two data file to be linked.

caldiffmatrix(a3,b3); %Calculate difference matrix, the difference of each row of a %datafile from another.
calcofu(a3,b3); %Calculation of U-Probability using frequency of data.
calcweight(A,us); % Calculating weight of each filed using M and U- Probability , %assuming M = 0.99
calcsumofweight(weight); %Calculate weight summation for every linked pair .

Example :
b3 = readfile('b3.csv');
a3 = readfile('a3.csv');
A = caldiffmatrix(a3,b3);
us = calcofu(a3,b3);
weight = calcweight(A,us);
sum = calcsumofweight(weight);
