Study Notes

Meaning Schema Modeling

  • Meaning schema is a semantic structure expressing a concept, mirroring human language understanding.
  • Meaning schemas help Google derive meaning and user intent from phrases.
  • Precise meaning derivation improves answer quality.
  • Meaning schemas were previously called intents.
  • Meaning schema modeling creates or improves schemas, adhering to unified principles.
  • Maximizing meaning schema composability is crucial for interpreting complex queries.
  • Grammar groups utterances used with a schema, crucial for training machine learning models.

Main Components of a Meaning Schema (MS)

  • Slots: Components of a schema, reflecting the schema's relationship with the slot. Slot names should describe the relationship.
  • Proto/Grammar Examples: Examples of the type of grammar for your schema
  • Signals: Signals that are used for the fulfillment of that schema.
  • Fulfillment: Fulfillment represents the ultimate goal of the schema's design to derive the meaning.

Modeling/Defining a Schema

  • Start by typing the schema name. If it exists, it will display.
  • If not, select "+ Create schema"
  • Use appropriate tags to provide metadata about the schema.
  • Describe the schema according to guidelines.
  • Use the “Enabled for Loose Parser” box (if needed)
  • Use existing guidelines for the description of the schema.
  • Configure slots and curation of collections for the MS.
  • Define slot descriptions and create examples.

Slot Configuration

  • Name and describe slots, clearly defining their relationship with the schema.
  • Follow guidelines for naming and describing slots.
  • Horizontal grammars cover cross-domain phrases (people, dates, etc)
  • Linking horizontal subgrammars to the schema is done at the schema level.

Scoping Collections and Overlapping Entities

  • Use Scopy to find collections associated with specific grammar patterns
  • Limit entities displayed by defining a slot.

Checking Top Traffic

  • Use the top traffic to gauge appropriate collections/grammar for your schema.

Adding/Expanding Grammar

  • Use the Expand Tool to match schema patterns within a Search Stack.

Query Examples

  • Use the Query Examples tool to view, add, edit or delete query examples.
  • Use "Thumbs up" to indicate in-scope queries and "Thumbs down" for out-of-scope queries.

Showcase Examples

  • Showcase examples clarify schema scope, demonstrating prototypical query patterns and slot annotations.
  • Showcase examples help build positive and negative examples.

Intent Lab Companion

  • Flags issues in schema workspaces.

Running Tests

  • KScorer Signals: Tools for scoring, suppressing and ranking interpretations.
  • JobRunner: Tool for generating KScorer and running evaluations (evals).
  • KE_Eval: (Knowledge Engine Evaluation) tool for measuring overall impact; runs comprehensive analysis.
  • KE_SxS: (Knowledge Engine Supplementary Score) similar to KE_Eval with targeted analyses.
  • QU_Eval: (Query Understanding Evaluation) measures query understanding quality at interpretation generation and ranking levels.
  • Use JobRunner to perform KE_Eval and SxS without fallback.
  • Use JobRunner for demos.

Review and Submission Process

  • Review workspaces.
  • Add external or internal reviewers.
  • Correctly describe the workspace and its associated links.
  • Submit for review.

Additional Tools and Resources

  • Lists tools, such as Meaning Explorer, Query Examples, JobRunner, Query Debugger, Scopy, Hume, and others.
  • Includes documentation and guides for various tasks and processes.
  • Explains how to get help from other people.
  • Includes a quiz for testing the understanding of the module.

Training Feedback

  • Use provided survey to provide feedback on the module.
