rdomains (version 0.5.0)

dmoz_cat: Get Category from DMOZ

Description

Fetches category (or categories) of content hosted by a domain according to DMOZ. The function checks if path to the DMOZ file is provided by the user. If not, it looks for dmoz_domain_cateory.csv in the working directory. It also returns results for prominent subdomains.

Usage

dmoz_cat(domains = NULL, use_file = NULL)

Value

data.frame with the original list, the content category of the domain, and the vintage of the list that supplied it

Arguments

domains

vector of domain names

use_file

path to the dmoz file, which can be downloaded using get_dmoz_data

Details

DMOZ closed in March 2017 and the snapshot shipped here is from 2015, so these labels describe the domain as it was a decade ago. The returned source_last_published column carries that vintage, and a warning is issued once per session. See source_vintage.

source_vintage for the provenance of every category source

Examples

if (FALSE) {
dmoz_cat(domains = "http://www.google.com")
dmoz_cat(domains = c("http://www.google.com", "http://plus.google.com"))
}
