What the Data for This Category Looks Like
Data related to business process guidance for basic telecommunications operations comes from official business handling guides, tariff standard documents, business hall location information, fault repair process details, new service launch announcements, and similar materials. Updates occur in real time alongside business adjustments. Documents are added when new packages or handling channels launch, and routine maintenance updates are performed weekly. Most documents are structured, containing fields such as handling steps, required materials, handling time limits, and consultation channels. Units include workdays, copies, addresses, phone numbers, and similar metrics. Some documents include cross-chapter linked process descriptions.
Constraints Imposed on Vector Models and Indexes by These Characteristics
Basic telecommunications operation business data has diverse types. Process documents are relatively long, while location documents are relatively short. Chunking must adapt to the structural characteristics of different documents. Data update frequency is not fixed. Temporary tariff adjustments or new service launches require rapid ingestion, so indexes must support incremental update modes. Documents contain a large number of telecommunications industry technical terms, so vector models must adapt to semantic understanding of these terms. Some data has timeliness requirements, so the index refresh cycle must be flexibly adjustable to avoid recalling outdated business information.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Most business handling documents for basic telecommunications operations are step-by-step or detailed. This length can fully cover a single handling process or a single tariff description |
| Overlap Length | 100–150 characters | Avoid splitting process steps across chunks, ensure contextual coherence |
maxToken | 8192 token | Adapts to the input limit of general-purpose vector models, meets contextual requirements for long documents |
| Similarity Threshold | 0.75–0.85 | Business handling processes have high keyword matching requirements. This range filters irrelevant results and retains precisely matched content |
| Single Search Limit | Top 8 results | Business process guidance needs to provide limited optional options; too many results will interfere with user judgment |
defaultToken | Calibrated based on actual testing | Adapts to the default output length of the currently used vector model, ensuring completeness of recalled results |
Three Common Mistakes
- Phenomenon: Index rebuilding tasks take more than 24 hours, and the index management page shows the switch is incomplete. Cause: Incremental index mode is not configured for high-frequency updated data of basic telecommunications operations. Full rebuilding traverses all historical documents, resulting in excessive time consumption.
- Phenomenon: Parameter error prompts are returned when adding indexes in batches. Cause: Chunking rules are not configured according to the structured fields of business documents. Complete documents containing multiple fields are directly passed in, causing index generation failure.
- Phenomenon: Recalled results contain content unrelated to the current handling scenario, such as recalling 5G package introductions when querying number portability processes. Cause: A reasonable similarity threshold is not set, or chunking logic for process documents is not optimized, resulting in semantic matching deviations.
How to Confirm Correct Configuration
- View the index management page of FastGPT v4.17.0, confirm that the trigger frequency of incremental update tasks matches the update rhythm of business documents.
- Manually upload a typical business handling document, check that the chunking results fully cover process steps with no content split across chunks.
- Initiate a simulated user consultation, verify that the number and similarity of recalled results meet preset rules.
- Submit a batch index request, check that the returned results include success identifiers with no parameter error prompts.
