1. Specify the search keyword.
2. Create PubMed search_query from the keyword.
3. Perform the search and limit it to the first 50 articles.
4. Extract the abstract texts and store them in an object.

Here is the code to do the preceding task:

        library(pubmed.mineR)        library(RISmed)        keyword <- "Deep Learning"        search_query <- EUtilsSummary(keyword, retmax=50)        summary(search_query)        extractedResult <- EUtilsGet(search_query)        pmid <- PMID(extractedResult)        years <- YearPubmed(extractedResult)        Jtitle <- Title(extractedResult)        articleTitle <- ArticleTitle(extractedResult)        abstracts <- AbstractText(extractedResult)

Once you have the abstracts in your R session, the next step is to do the pre-processing ...
