Language Family Tree Depth Lookup
Resolve actual caller family-tree forest depth/lineage with cycle detection and explicit roots, not fixed lineage claims; one-parent model does not represent contact, disputed or overlapping classifications.
Description
A family-tree forest gives each node at most one parent.
A family-tree forest gives each node at most one parent. Depth and lineage depend on the caller’s explicit classification.1
Enter aligned nonempty distinct ASCII node identifiers, parent indices −1 or valid zero-based node indices, and exact selected name. Validate all components for cycles; return depth and selected-node-to-root list.
When to use Language Family Tree Depth Lookup
Use Language Family Tree Depth Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. A selected internal node is allowed. Contact, disputed and overlapping classifications are excluded.
Prepare explicit text tokens, annotated language observations, caller mappings or a supported locale as requested. Preserve source evidence and the stated Unicode counting convention.
How to use Language Family Tree Depth Lookup and understand its results
- Prepare explicit text tokens, annotated language observations, caller mappings or a supported locale as requested. Preserve source evidence and the stated Unicode counting convention.
- Enter callerFamilyNodeNames, callerParentNodeIndices, selectedNodeName using the field table and calculation rules, then run the tool.
- Read selectedNodeDepth, selectedLeafToRootLineage. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| callerFamilyNodeNames | Caller family node names | list of string | Required |
| callerParentNodeIndices | Caller parent node indices | list of number | Required |
| selectedNodeName | Selected node name | string | Required |
Enter aligned nonempty distinct ASCII node identifiers, parent indices −1 or valid zero-based node indices, and exact selected name. Validate all components for cycles; return depth and selected-node-to-root list.
depth=number of parent edges to a root; root parent=−1 Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| selectedNodeDepth | Selected node depth | number |
| selectedLeafToRootLineage | Selected leaf to root lineage | list of string |

}Limitations and assumptions
A selected internal node is allowed. Contact, disputed and overlapping classifications are excluded.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Word Order Typology SOV/SVO/VSO Lookup: Word-order labels describe annotated subject, verb and object positions in a clause. One clause is not a language’s dominant typology. For a complementary task, use Semantic Shift Type Classifier: Meaning extensions can be modeled as sets of referents. Gained and lost members distinguish broadening, narrowing and overlapping changes.
