When a query is returned by OnePetro inside the web page with the results also comes the dc_type or document type for all the papers that returned from that search.
The type of papers are:
If we want to know what type of papers are available for a particular search we follow these steps:
Our search is for the exact words “well test”. How many papers return from that search?
library(petroOne)
my_url <- make_search_url(query = "well test",
how = "all") # exact match
get_papers_count(my_url)## [1] 12066result <- read_onepetro(my_url)
sdc <- summary_by_doctype(result)
sdc## # A tibble: 7 x 2
## name value
## <chr> <dbl>
## 1 Chapter 8
## 2 Conference paper 9298
## 3 General 193
## 4 Journal paper 2529
## 5 Media 5
## 6 Other 8
## 7 Presentation 25We see that the most numerous category is conference papers followed by journal. The total number of papers is about 12066
Depending of the words we are searching, the document types that return from the search may not be the same in all cases. For instance, in this case, we don’t get the type for Other or Chapter.
