Giambattista Bloisi 3c66e3bd7b Create dedup record for "merged" pivots 
Do not create dedup records for group that have more than 20 different acceptance date
 2024-01-10 22:59:52 +01:00
Giambattista Bloisi 02636e802c SparkCreateSimRels: 
- Create dedup blocks from the complete queue of records matching cluster key instead of truncating the results
- Clean titles once before clustering and similarity comparisons
- Added support for filtered fields in model
- Added support for sorting List fields in model
- Added new JSONListClustering and numAuthorsTitleSuffixPrefixChain clustering functions
- Added new maxLengthMatch comparator function
- Use reduced complexity Levenshtein with threshold in levensteinTitle
- Use reduced complexity AuthorsMatch with threshold early-quit
- Use incremental Connected Component to decrease comparisons in similarity match in BlockProcessor
- Use new clusterings configuration in Dedup tests

SparkWhitelistSimRels: use left semi join for clarity and performance

SparkCreateMergeRels:
- Use new connected component algorithm that converge faster than Spark GraphX provided algorithm
- Refactored to use Windowing sorting rather than groupBy to reduce memory pressure
- Use historical pivot table to generate singleton rels, merged rels and keep continuity with dedupIds used in the past
- Comparator for pivot record selection now uses "tomorrow" as filler for missing or incorrect date instead of "2000-01-01"
- Changed generation of ids of type dedup_wf_001 to avoid collisions

DedupRecordFactory: use reduceGroups instead of mapGroups to decrease memory pressure

Giambattista Bloisi 2caaaec42d Include SparkCleanRelation logic in SparkPropagateRelation

Giambattista Bloisi fab9920271 DispatchEntitiesSparkJob: manage all entity types together, support filtering by dataInfo.invisible flag 2023-08-09 15:41:43 +02:00
Giambattista Bloisi af49424b59 Add a "CleanRelation" action after the PropagateRelation to filter out all relations that have been deleyted by inference or that are pointing to dangling entities 2023-08-04 14:27:39 +02:00
Giambattista Bloisi e64c2854a3 Refactor Dedup process to use Spark Dataframe API and intermediate representation with Row interface 
JsonPath cache contention fixed by using a ConcurrentHashMap
Blacklist filtering performance improvement
Minor performance improvements when evaluating similarity
Sorting in clustered elements is deterministic (by ordering and identity field, instead of ordering field only)
