CompositeDocAdditionalChecksums

AI Overview😉

  • The potential purpose of this module is to calculate and store various checksums (digital fingerprints) of a document, which can be used to identify duplicate or similar content. This helps Google to detect and prevent duplicate or low-quality content from ranking high in search results.
  • This module could impact search results by influencing the ranking of documents that have similar or duplicate content. If a document has a high simhash-v2 significance, it may be considered more trustworthy and unique, which could improve its ranking. On the other hand, documents with low simhash-v2 significance or duplicate content may be penalized and ranked lower.
  • To be more favorable for this function, a website could focus on creating high-quality, unique, and original content that is not duplicated elsewhere. This could include using plagiarism detection tools, ensuring that content is well-researched and cited, and avoiding thin or low-value content. Additionally, websites could ensure that their content is properly indexed and crawled by Google, which could help the algorithm to better understand the content and calculate its simhash-v2 value accurately.

Additional checksums of the document.

Attributes

  • NoTransientChecksum96 (type: String.t, default: nil) - Same as ContentChecksum96 but without transient boilerplate.
  • SimHash (type: String.t, default: nil) - Deprecated. Use simhash_v2 and simhash_v2_significance instead.
  • SimHashIsTrusted (type: boolean(), default: nil) -
  • simhashV2 (type: String.t, default: nil) - Simhash-v2 is generated by SimHashParseHandler, designed as a complete replacement of simhash-v1 (a.k.a. the original simhash above) from ApproxDupsParseHandler. Simhash-v2 uses a revised algorithm so that it is expected to work better in most cases than simhash-v1. They coexist in current transition period, then simhash-v1 will be retired.
  • simhashV2Significance (type: float(), default: nil) - Simhash-v2-significance is used to describe the confidence about the corresponding simhash-v2 value. It is defined as the average absolute difference from zero of all internal state components when finalizing a simhash-v2 value in HashMultiSetDotCauchy. We used to compare the significance against some pre-defined threshold (default: 20) to get a boolean value "trusted_simhash_v2". However, it is possible that this field is missing while "simhash_v2" is present, in such case (1) Use "SimHashIsTrusted" instead if it is present, AND/OR (2) Assume "simhash_v2" is trusted if its value is non-zero.
