Data Merging & Cleaning

Raw data are collected from database search result using key terms describe in the paper. The file ** Raw data from each database are trimmed to only include the following information / columns:

- Authors                : all paper authors
- Title                  : paper titles
- Title_2                : additional identifier of paper title
- Record_link            : first URL of document
- DOI                    : Digital identifier
- Year                   : Publication year of paper

Then this data are compiled for assessment of title correlation. Compiled data is called: database_title_final_df.xlsx

Title correlation

• Broad topics associated with ASE-systems are clustered to create a commonly used expression for ASE-paper

• These expressions are used to create a unique list of words most used in ASE papers.

• From the combinations of these expressions, each word is extracted and stored in a unique list to avoid duplicates, forming a bag of words (BOW)

• he BOW is used to assess the correlation of paper titles.
