-- `schema.system_prompt`: Injected as the system role message -- `schema.prompt_template`: A Python `str.format`-style template rendered per chunk, with placeholders: - - `{variables}`: A human-readable list of variables with types and allowed values - - `{text}`: The current text chunk - - `{context}`: Optional extra key-values (if provided by advanced flows) - -Examples: - -```text -System: {schema.system_prompt} -User: {schema.prompt_template.format(variables=..., text=..., context=...)} -``` - -Notes: -- For Multiple schemas, the prompt is built by concatenating sub‑schema prompts under headings. -- Token estimation uses these same prompts, so edits affect cost estimates. - - - -### Variable Examples - -```yaml -# Simple string field -- name: "company_name" - description: "Name of the company" - data_type: "string" - required: true - -# Number with validation -- name: "revenue" - description: "Revenue in USD" - data_type: "number" - required: false - validate_in_text: true - -# String field with allowed values (essentially an enum) -- name: "sector" - description: "Business sector" - data_type: "string" - allowed_values: ["technology", "finance", "healthcare"] - required: false - -# Boolean field -- name: "is_public" - description: "Whether company is publicly traded" - data_type: "boolean" - required: false - -# List of numbers with allowed values -- name: "quarterly_growth_rates" - description: "Quarterly revenue growth rates in percent" - data_type: "[number]" - allowed_values: [0, 5, 10, 15, 20, 25, 30] - required: false -``` - -### Validation Features - -#### Text Validation -```yaml -- name: "commodity_type" - description: "Type of commodity mentioned" - data_type: "string" - validate_in_text: true # Only extract if explicitly mentioned in text -``` - -#### Allowed Values -#### Cleaning & Validation Semantics - -- Required fields: If a required field has no valid value, the item is dropped. - - Simple schema: the whole response for a chunk is discarded. - - Nested schema: the specific object is discarded; the chunk may still yield other objects. -- Null-like strings in string fields (e.g., "none", "null", "unknown", "n/a", "") are filtered unless explicitly listed in `allowed_values`. -- `validate_in_text: true` keeps only string values that literally appear in the source text (case-insensitive). -- For Multiple schemas, nested sub-schemas are unwrapped in outputs (e.g., `books: [...]`, not `books: {books: [...]}`). -- For Nested schemas, if `container_name` is omitted, it defaults to `"instances"`. -```yaml -- name: "sentiment" - description: "Overall sentiment" - data_type: "string" - allowed_values: ["positive", "negative", "neutral"] -``` - -## Schema Examples - -### Financial Report Analysis -```yaml -schema_type: "nested" -container_name: "financial_metrics" -variables: -

-### Fixed Window Split - -Splits text into fixed-size windows with optional overlap: - -```yaml -data_preprocessing: - splitting: - type: "FixedWindowSplit" - window: 5 # Number of sentences per chunk - stride: 2 # Number of sentences to overlap -``` - -**Best for**: -- Consistent chunk sizes -- Capturing context across boundaries -- Processing structured documents - -### Regex Split - -Splits text using custom regular expressions: - -```yaml -data_preprocessing: - splitting: - type: "RegexSplit" - pattern: "\n\n" # Split on double newlines -``` - -**Best for**: -- Custom document formats -- Specific structural patterns -- Domain-specific splitting needs -

Optimize Batch Size -```yaml -llm_extraction: - batch_size: 20 # Larger batches can reduce overhead - max_workers: 2 # Parallel processing -``` - -## Best Practices - -### 1. Start with Input Token Estimation -Always begin with `estimate_input_token_cost` since it's free and gives you a baseline. - -### 2. Use Representative Samples -For `estimate_total_cost`, use a sample size that represents your full dataset: -- **Small datasets** (< 1000 records): Use 10-20% of your data -- **Medium datasets** (1000-10000 records): Use 5-10% of your data -- **Large datasets** (> 10000 records): Use 1-5% of your data - -### 3. Account for Caching -If you plan to use caching, your actual costs will be lower than estimates since repeated chunks won't be re-processed. - -### 4. Set Budget Limits -```yaml -llm_extraction: - track_cost: true - max_budget: 100.0 # Stop processing if cost exceeds $100 -``` - -### 5.

It saves money by avoiding duplicate API calls, and the performance overhead is minimal. Enable caching unless you have a specific reason not to. + +**Default Behavior**: Caching is **enabled by default** using the SQLite backend. The cache is stored at `.delm/cache` (relative to your current working directory). You don't need to configure anything to start using it. + +## What is Caching? + +DELM caches LLM responses using an **exact-match** key system. When you process text with the same prompt, model, and temperature settings, DELM returns the cached result instead of making a new API call. + +### How It Works + +The cache key is computed from: +- The rendered prompt text (including chunk content and template variables) +- The system prompt +- The model name (e.g., `gpt-4o-mini`) +- The temperature setting + +If all of these match exactly, the cached response is returned. This means **identical inputs always return identical outputs**, even across different runs. + +### Benefits + +- **Cost reduction**: Avoid paying for duplicate API calls +- **Performance improvement**: Cached responses are returned instantly +- **Consistency**: Identical inputs always return identical outputs +- **Resume capability**: Failed runs can resume from cached results + +### Key Use Case: Scoring Strategies and Filters + +Caching is particularly valuable when using **relevance scoring and filtering**.

It does **not** include: +- The system prompt (sent separately in the API call) +- Instructor's JSON schema wrapper (added automatically during the API call) + +This preview is useful for debugging your template and variable formatting, but the actual LLM receives additional instructions from Instructor for structured output. + +## Best Practices + +### 1. Start Simple + +Begin with clear variable descriptions before customizing the template: + +```python +# Good: Clear, specific description +ExtractionVariable( + name="price", + description="The numeric price value mentioned (without currency symbol)", + data_type="number" +) + +# Less effective: Vague description +ExtractionVariable( + name="price", + description="price", + data_type="number" +) +``` + +### 2. Be Explicit About Edge Cases + +```python +ExtractionVariable( + name="revenue", + description="Quarterly revenue in millions. If revenue is stated in billions, convert to millions. If 'year-to-date' or 'annual' revenue is mentioned, do NOT extract.", + data_type="number" +) +``` + +### 3. Test Incrementally + +1. Start with default prompts +2. Run evaluation to identify issues +3. Adjust descriptions for low-performing fields +4. If descriptions aren't enough, customize the prompt template +5. Use system prompt for overall behavior changes + +### 4. Avoid Redundancy + +Don't repeat the same instructions in multiple places. If all variables need the same rule, put it in the prompt template or system prompt: + +```python +# Less efficient: Repeating in every variable +ExtractionVariable( + name="price", + description="Price value. Only extract if explicitly mentioned.", + data_type="number" +) +ExtractionVariable( + name="volume", + description="Volume value. Only extract if explicitly mentioned.", + data_type="number" +) + +# Better: Put general rule in prompt template +prompt_template = """Extract the following (ONLY if explicitly mentioned): +{variables} + +Text: {text}""" +``` + +### 5. Consider Token Cost + +Longer prompts cost more. Find the balance between clarity and conciseness: + +```python +# Verbose (higher cost) +description="This field should contain the price value mentioned in the text. The price should be a numeric value without any currency symbols or units. If a price range is given, extract the midpoint. If multiple prices are mentioned, extract all of them as a list." + +# Concise (lower cost, equally clear) +description="Numeric price value without symbols. For ranges, use midpoint. Extract all if multiple." +``` + diff --git a/docs/user-guide/schemas.md b/docs/user-guide/schemas.md new file mode 100644 index 0000000..e85037f --- /dev/null +++ b/docs/user-guide/schemas.md @@ -0,0 +1,223 @@ +# Schema Reference + +Schemas define the structured outputs that DELM extracts from your documents.
