Cognitive service for a Natural Language Processing (NLP) solution.
Helps to build a custom knowledge base to provide a natural conversation layer over your common questions and answers.

Anomaly Detector
Finds data that is an outlier or is out of trend in time-series data. It does not analyze content supplied by users for offensive content such as adult, racy, or
gory Images.

Content Moderator
Cognitive service that identifies content that is potentially offensive, including images that may contain adult, racy, or gory content. It flags such content automatically for a human to review in a portal.

Smart Labeler

Language Understanding - remove punctuations such as dots, commas, brackets, and others from your utterances before your model gets trained or your app's endpoint queries get predicted. However, it does not eliminate the effect of accented characters.

Language Understanding - replace accented characters, also known as diacritics, with regular characters.
Allows you to ignore the effect of diacritics during your app's training and prediction.
Only available for the supported languages like Spanish, Portuguese, Dutch, French, German, and Italian.

Phrase list
Language Understanding - list of similar words or phrases that can be used by your model as a domain-specific vocabulary.
Example in travel industry: Single, Double, Queen, King, and Twin as a phrase list feature, so the app can recognize from the utterances preferences for a hotel room type.
The phrase list feature can improve the quality of your NLU app understanding of intents and entities

QnA - Property specifies if the field in the index can be used as a filter and can restrict the list of documents returned by the search.
The filterable property is a Boolean value defined on a field in the index.

QnA - allows other fields to be used for sorting results
By default, search results are ordered by score.

QnA - returns a hit count by category, for example the number of results by test type.

QnA - Boolean; if set to true, includes the field in the results of the search, if set to false the field will not be included in the search result.

Knowledge store
Azure Cognitive Search - place in Azure Storage, where is stored data created by a Cognitive Search enrichment pipeline.
It is used for independent analysis or downstream processing in non-search scenarios like knowledge mining.
It is an enriched (created/generated by the skillset) content stored:
  • tables TAB3 (key phrase extraction)
    table projections require the data to be mapped to the knowledge store using outputFieldMappings with:
    • sourceFieldName
    • targetFieldName
  • blob containers in storageContainer.
When you save enrichments as a table projection you need to specify:
  • source - path to projection
  • tableName - name of table in Azure Table storage

Enhance and shape the data.
Type of projections:
  • File (images )
  • Object (JSON)
  • Table (dictionary)
Enrichment process of Cognitive Search enrichment pipeline.
Move a document through a sequence of enrichments that invoke atomic transformations, such as recognizing entities or translating text.
  • always a search index.
  • can be projections in a knowledge store.
Search index and knowledge store are mutually exclusive products of the same pipeline.
They are derived from the same inputs but their content is structured, stored, and used in different applications.

Azure Cognitive Search, enrichment - optional and used to reference an Azure Key Vault for the skillset, not for the knowledge store.
