Model Access and Configuration for Tourist Attraction

What the Data for This Category Looks Like

Data sources for tourist attraction investment research include the attraction’s internal operation systems, public documents from cultural and tourism regulatory authorities, booking data from online travel platforms, and tourist review texts. Update rhythms vary significantly: passenger flow and booking data are updated daily or in real time; facility inspection reports are generated irregularly alongside maintenance activities; cultural and tourism policy documents are updated at their release timelines; and tourist review texts are generated in real time. Document structures include structured reports, semi-structured inspection records, unstructured policy documents, and review texts. Field units use exclusive identifiers such as person-times, yuan, and percentages.

What Constraints Do These Characteristics Impose on the Model Access and Configuration Link

Multi-source, multi-format data requires the model access layer to support parsing multiple file types and metadata formats, with corresponding parsing rules needing configuration. Data with different update rhythms requires different recall refresh strategies: real-time passenger flow data needs low-latency call parameters, while monthly policy documents can use daily refresh recall tasks. Exclusive fields and units require models to retain field identifiers during embedding and recall, so metadata filtering rules must be configured to match the precise query needs of attraction investment research. Unstructured tourist review texts account for a large share of the dataset, so batch parameters for embedding models must be adjusted to adapt to mixed parsing scenarios of short and long texts.

Recommended Configuration Values

Configuration Item	Recommended Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`1000 MB`	Attraction operation reports and inspection report files typically do not exceed 800 MB, with reasonable redundant space reserved
`maxContext`	`8000–12000 characters`	Attraction investment research documents include long operation reports and multiple policy documents; this range prevents model context overflow
`embedding_batch_size`	`32 entries`	Attraction data includes short-text tourist reviews and long-text policy documents; a 32-entry batch balances parsing speed and memory usage
`recall_top_k`	`Top 6–8 entries`	Attraction investment research needs to cover multi-dimensional information including passenger flow, facilities, and policies; this range balances recall coverage and content accuracy
`PARSE_FILE_TIMEOUT_SECONDS`	`120 seconds`	Large attraction annual operation reports take longer to parse; this duration prevents parsing timeout interruptions for standard files
`filter_metadata_fields`	`["receiving person-times", "revenue amount", "device ID"]`	Exclusive fields in attraction data should be used as filtering conditions to improve the recall accuracy of investment research queries

The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.

Three Common Misconfigurations

Issue: Unable to select latest models such as Zhipu Embedding-3 and CharGLM-4 when configuring embedding_model. Cause: No third-party model transit gateway configured in the model access layer, only built-in model lists are used.
Issue: Docker-deployed model access service throws 500 Internal Server Error and restarts indefinitely, with logs displaying token encoder not found. Cause: Model token encoder dependency packages are not mounted, or model key paths are not correctly configured in environment variables.
Issue: Only 2 recall results are returned after initiating an investment research query, which does not match the configured recall_top_k value. Cause: filter_metadata_fields is not correctly configured, causing metadata filtering rules to exclude most matching documents.

How to Confirm Proper Configuration

Upload a single attraction annual operation report, check that the upload progress prompt matches the UPLOAD_FILE_MAX_SIZE configuration, with no file truncation errors.
Initiate an investment research query containing multi-dimensional keywords, verify that the context length of returned results does not exceed the threshold set by the maxContext configuration, with no context overflow warnings.
Test filtering queries using the "receiving person-times" field from filter_metadata_fields, confirm that recalled results only include documents matching this field.
Check the running logs of the model access service, with no token encoder not found or model connection timeout errors.
