dief (version 1.2)

diefk: Compute metric dief@k

Description

This function computes the dief@k metric at a given k (number of answers).

Usage

diefk(inputtrace, inputtest, k = -1)

Arguments

inputtrace

dataframe with the answer trace. Attributes of the dataframe: test, approach, answer, time.

inputtest

string that specifies the specific test to analyze from the answer trace.

k

number of answers to compute diefk. By default, the function computes the minimum of the total number of answers produced by the approaches.

Examples

# NOT RUN {
# Compute dief@k when k is the number of answers produced 
# by the approach theat generated the least answers. 
diefk(traces, "Q9.sparql") 
# Compute dief@k while producing the first k=1000 answers. 
diefk(traces, "Q9.sparql", 1000)
# }
