    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.
