Use regular expression to split multiple-sentence titles

Context and Problem Statement

Some entry titles are composed of multiple sentences, for example: “Whose Music? A Sociology of Musical Language”, therefore, it is necessary to first split the title into sentences and process them individually to ensure proper formatting using ‘Sentence Case’ or ‘Title Case

Considered Options

Decision Outcome

Chosen option: “Regular expression”, because we can use Java internal classes (Pattern, Matcher) instead of adding additional dependencies

Positive Consequences

  • Less dependencies on third party libraries
  • Smaller project size (ICU4J is very large)
  • No need for model data (OpenNLP is a machine learning based toolkit and needs a trained model to work properly)

Negative Consequences

  • Regular expressions can never cover every case, therefore, splitting may not be accurate for every title
