PM4Py 로그 필터링하는 법 (variant 기준 필터링)

Variant란, 하나의 유니크한 프로세스의 진행 경로를 말한다. 예를 들어, <a,b,c,d>가 10번, <a,c,b,d>가 5번 일어난 이벤트 로그가 있다고 하자. 그렇다면 이 이벤트 로그의 variant는 <a,b,c,d>, <a,c,b,d>의 두 개가 된다. 이번 포스팅에서는 PM4Py를 이용하여 variant를 기준으로 이벤트 로그를 필터링하는 방법에 대해 알아보겠다. 

 

1. 우선, xes 파일을 import하여 이를 log에 저장해 준다.

import os
from pm4py.objects.log.importer.xes import factory as xes_importer

log = xes_importer.import_log(os.path.join("input_data","receipt.xes")) #괄호 안에 원하는 파일의 경로를 쓴다

 

2. 어떤 variant를 필터링할 것인지를 결정하기 위해 이벤트 로그가 어떤 variant로 구성되어 있는지를 파악한다.

from pm4py.algo.filtering.log.variants import variants_filter

variants = variants_filter.get_variants(log)
print(variants.keys())

이 variants는 variant를 key 값으로 가지고 그 variant에 해당하는 케이스 정보들을 value 값으로 가지는 dictionary이다. 그래서 어떤 variant가 있는지를 파악하기 위해 variants의 key 값을 출력했다. 다음과 같은 결과가 나오면 성공이다.

 각 variant의 빈도수를 파악하고 싶다면 다음 코드를 입력한다.

from pm4py.statistics.traces.log import case_statistics

variants_count = case_statistics.get_variant_statistics(log)
variants_count = sorted(variants_count, key=lambda x: x['count'], reverse=True)
print(variants_count)

다음과 같은 결과가 나오면 성공이다.

[{'variant': 'Confirmation of receipt,T02 Check confirmation of receipt,T04 Determine confirmation of receipt,T05 Print and send confirmation of receipt,T06 Determine necessity of stop advice,T10 Determine necessity to stop indication', 'count': 713}, {'variant': 'Confirmation of receipt,T06 Determine necessity of stop advice,T10 Determine necessity to stop indication,T02 Check confirmation of receipt,T04 Determine confirmation of receipt,T05 Print and send confirmation of receipt', 'count': 123}, {'variant': 'Confirmation of receipt', 'count': 116}, {'variant': 'Confirmation of receipt,T02 Check confirmation of receipt,T06 Determine necessity of stop advice,T10 Determine necessity to stop indication,T04 Determine confirmation of receipt,T05 Print and send confirmation of receipt', 'count': 115}, ...

3. 원하는 variant만을 남기고 나머지를 필터링한다.

apply의 두 번째 인수로 원하는 variant를 list로 넣어준다.

filtered_log1 = variants_filter.apply(log, ["Confirmation of receipt,T02 Check confirmation of receipt,T04 Determine confirmation of receipt,T05 Print and send confirmation of receipt,T06 Determine necessity of stop advice,T10 Determine necessity to stop indication"])

잘 필터링되었는지 확인하기 위해 filtered_log1의 variant가 무엇이 있는지를 2번에서 쓴 것과 같은 방법으로 확인해본다.

variants_count_filtered_log1 = case_statistics.get_variant_statistics(filtered_log1)
print(variants_count_filtered_log1)

다음과 같은 결과가 나오는 것을 확인함으로써 필터링이 잘 되었음을 알 수 있다.

[{'variant': 'Confirmation of receipt,T02 Check confirmation of receipt,T04 Determine confirmation of receipt,T05 Print and send confirmation of receipt,T06 Determine necessity of stop advice,T10 Determine necessity to stop indication', 'count': 713}]

만약 해당 variant만을 제거하는 필터링을 하고 싶다면 다른 필터들과 마찬가지로 아래 코드와 같이 parameter의 positive 값을 False로 전달해주면 된다.

filtered_log2 = variants_filter.apply(log, ["Confirmation of receipt,T02 Check confirmation of receipt,T04 Determine confirmation of receipt,T05 Print and send confirmation of receipt,T06 Determine necessity of stop advice,T10 Determine necessity to stop indication"], parameters={"positive": False})

4. 자동 필터링을 원한다면, 다음 코드를 통해 필터링한다. 

자동 필터링의 식은 시작/끝 액티비티를 필터링할 때와 같다. 다음 포스팅의 4번 윗 부분을 참고한다.

2019/09/11 - [Process Mining - Tools/pm4py] - PM4Py 로그 필터링하는 법 (시작/끝 액티비티 기준 필터링)

PM4Py 로그 필터링하는 법 (시작/끝 액티비티 기준 필터링)

auto_filtered_log = variants_filter.apply_auto_filter(log)

 

이번 포스팅에서는 variant를 기준으로 이벤트 로그를 필터링하는 방법에 대해 알아보았다.
