What data for this category looks like
Marketing-related data for film theaters comes primarily from scheduling management systems, box office statistics backends, member profile databases, and official marketing material libraries. Update cadence follows these rules: daily updates for showtimes on the current day and the next 7 days, hourly sync of box office data, and concentrated updates of exclusive marketing materials 1 to 2 weeks before a new film releases. Document structure is split into two categories: structured fields and unstructured materials. Structured fields include film unique identifier, release date, viewing city, session unit price, and schedule tag. Their respective units are none, YYYY-MM-DD, city name, yuan, and schedule interval. Unstructured materials include poster image links, short video scripts, and official account tweet templates.
Constraints on multi-turn dialogue and prompt engineering
Structured fields are numerous and closely linked. Multi-turn dialogue must continuously retain contextual information such as schedule and viewing city, to avoid extraction errors caused by context truncation. Unstructured materials include multimedia links. Prompts must explicitly require converting links to displayable formats, otherwise only text links will be returned. Data updates occur at high frequency. A real-time recall strategy must be configured to ensure that showtime information used in dialogue matches the current schedule. Marketing content must adapt to multiple channels. Multi-turn dialogue must retain historical modification opinions for channel preferences, to avoid repeated adjustments.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000-12000 characters | Multi-turn dialogue for film marketing must retain complete context of schedule, user questions, and modification opinions to avoid loss of key information |
RECALL_TOP_N | Top 6-8 entries | The volume of film marketing materials is large. Too many recalled entries will cause content redundancy, while too few may miss key schedule or user tag information |
PROMPT_TEMPLATE | Spliced in the order of film structured information + user requirements + historical dialogue | Film data includes structured fields and unstructured multimedia materials. Context priority must be clearly defined to ensure generated content fits the business scenario |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Marketing materials may include high-definition posters and trailer links. The parsing process takes a long time, so sufficient time must be reserved for parsing |
MAX_TOKENS | 2000-3000 characters | Film marketing content requires complete short video scripts or official account tweets to be output, so sufficient output length must be reserved |
SIMILARITY_THRESHOLD | 0.75-0.85 | Film-related keywords such as film titles and schedules have high recognizability. Thresholds that are too high will miss relevant materials, while thresholds that are too low will introduce irrelevant content |
The parameter values provided on this page are all conventional recommendations used as starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: A
connection errorprompt appears when calling the model, even if a proxy is enabled and the issue cannot be resolved. Cause: ThePROXY_URLparameter is not configured, or the proxy address does not adapt to regional restrictions from the model service provider. - Symptom: Poster links returned by the knowledge base are only displayed as text, and cannot be presented as images in dialogue. Cause: The prompt does not explicitly require converting image links to standard image display formats, and no output rules are specified.
- Symptom: Key variables cannot be accurately extracted during multi-turn dialogue. For example, when a user asks "Showtimes for The Wandering Earth in Shanghai next week", the viewing city, schedule, and film title cannot be correctly extracted. Cause: The prompt does not define field rules for structured extraction, and does not clearly mark the names of variables to be extracted.
How to Verify Correct Configuration
- Initiate a test question that includes historical dialogue, showtime information, and material links, and check whether the returned content retains complete contextual information.
- Upload marketing materials that include poster links, initiate a question requesting image display, and check whether the output format meets expectations.
- Enter a vague question that includes a film title, schedule, and viewing city, and check whether the corresponding fields can be accurately extracted.
- Adjust configuration item parameters, initiate multiple consecutive questions, and check whether context loss or content truncation occurs.
