Deduplication / Decontamination

[chschroeder]

Hi,

dolma is a wonderful tool, and I m successfully using it for many steps of my pipeline.

Strangely, I can manage to get it working for (paragraph-level) deduplication. When applied in a similar setting, for decontamination, however, it never assigns any attributes:

What is the problem?

Compared to the "normal" paragraph deduplication, when trying to just apply an existing bloom filter, there are no dedupe attributes in the resulting attribute files. I have already experimented with the desired_false_positive_rate overlap_threshold parameter, but without any success.

{"attributes":{"paragraphs_bff_duplicates":[]},"id":"URL1"}
{"attributes":{"paragraphs_bff_duplicates":[]},"id":"URL2"}
{"attributes":{"paragraphs_bff_duplicates":[]},"id":"URL3"}

Infos about my setup:

I am using the latest dolma 1.0.3 release. My latest minimum working example is based on configs/dolma-v1_5/decontamination.

Here are my config files

create-bloomfilter.yaml:

documents:
  - benchmarks.jsonl.gz  # these are the files I want to filter with the decontamination step

dedupe:
  name: decontaminate
  paragraphs:
    attribute_name: paragraphs_bff_duplicates
  skip_empty: true

bloom_filter:
  read_only: false
  estimated_doc_count: 73543
  #size_in_bytes: 104857  # 100 MB; smaller causes too many FPs
  desired_false_positive_rate: 1e-3  # TOD: 1e-15
  file: decontamination_bloom_filter.bin

processes: 4 

decontaminate.yaml:

documents:
  - tmp/v0/documents/*.gz

work_dir:
  input: work/para/input
  output: work/para/output

dedupe:
  name: decontaminate
  paragraphs:
    attribute_name: paragraphs_bff_duplicates
  skip_empty: true

bloom_filter:
  read_only: true
  estimated_doc_count: 288347 
  desired_false_positive_rate: 1e-3
  file: decontamination_bloom_filter.bin

processes: 3

Here is the output
