##Overview

It is envisaged that different users will start at different points of their data preparation. THis section is intended to explain the fake data I have created so the type of data used for the examples can be better understood.

There are several data files used. These are detailed below

Gastroscopy

Raw datasets:

#####TheOGDReportFinal A dataset containing fake upper GI endoscopy reports. The report field is provided as a whole report without any fields having been already extracted. There are 2000 rows

#####PathDataFrameFinal A dataset containing fake upper GI pathology reports. The report field is provided as a whole report without any fields having been already extracted. There are 2000 rows

####Pre-extracted datasets:

#####Myendo This has been extracted using the Extractor method as follows from the raw text within Mypath:

mywords <- c("OGDReportWhole","HospitalNumber","PatientName",
             "GeneralPractitioner","Dateofprocedure","Endoscopist",
             "Secondendoscopist","Medications","Instrument","ExtentofExam",
             "Indications","ProcedurePerformed","Findings")
Extractor(TheOGDReportFinal,"OGDReportWhole",mywords)

####Mypath

This has been extracted using the Extractor method as follows from the raw text within Mypath:

mywords<-c("HospitalNumber","PatientName","DOB","GeneralPractitioner",
           "Dateofprocedure","ClinicalDetails","Macroscopicdescription",
           "Histology","Diagnosis")
Extractor(PathDataFrameFinal,"PathReportWhole",mywords)

The original dataset has also been added as “PathReportWhole”,

##Colonoscopy

###Raw datasets

####ColonFinal

####PathDataFrameFinalColon

A dataset containing fake lower GI pathology reports. The report field is provided as a whole report without any fields having been already extracted. There are 2000 rows.
