litsearchr is an R package to partially automate search term selection for systematic reviews using keyword co-occurrence networks. In addition to identifying search terms, it can write Boolean searches and translate them into over 50 languages.
Use topic modeling to identify terms you likely want to exclude because they are only found in an unwanted topic cluster and not found within clusters of knowledge that should be retrieved.
