get_links: Load links between MAG and ProQuest

In f-hafner/magutils: Utilities for loading data from MAG-Proquest database

Load links between MAG and ProQuest

Description

Load the links between records in MAG and in ProQuest. The links are stored as a table in the database. The links can be either between PhD graduates and MAG authors, or PhD advisors and MAG authors.

Usage

get_links(conn, from, min_score = 0.7, ...)

Arguments

conn	An object of class SQLiteConnection to a sqlite database.
from	A string with options to be queried: "advisors" or "graduates".
min_score	Minimum score for links to accept. Numeric between 0 and 1.
...	Additional arguments to be passed to make_tbl_output. If not specified, a lazily evaluated table without limit is returned. Partially specified arguments are completed with dots_tbl_output.

Details

For advisor links, a high threshold for min_score (0.95 or higher) is recommended, and the function throws a message if that is not the case. The reason for this is that there seem to be many false positives when using a lower threshold.

Value

A query of linked goid-AuthorId.

Examples

conn <- connect_to_db(db_example("AcademicGraph.sqlite"))
graduate_links <- get_links(conn, from = "graduates", min_score = 0.7)
advisor_links <- get_links(conn, from = "advisors", min_score = 0.7)
