What the Data for This Category Looks Like
Data for aerospace equipment financial reports comes primarily from public regular reports of listed aerospace enterprises, public industry data released by national defense science, technology and industry authorities and industry associations, and special announcements for aerospace missions. Update cycles fall into three categories: annual reports, quarterly reports, and temporary mission announcements. Document structures are split by business segments, including sub-modules such as launch vehicles, satellite manufacturing, and ground equipment. Documents include fields like revenue amount, R&D investment, and core equipment parameters. Most field units use professional standards, including ten thousand yuan, units, tons, and low Earth orbit carrying capacity (kilograms/tons). Single financial report documents are typically lengthy, containing multiple sections of professional technical descriptions and financial details.
Constraints Imposed on Knowledge Base Retrieval and Recall
Multi-source, scattered data for aerospace equipment financial reports requires the retrieval link to support cross-source metadata matching. This prevents mixing in general industry data from non-target enterprises. Complex business segment structures require retrieval to accurately match segment-specific terminology. Generalized keyword matching cannot be relied upon. The presence of professional fields and specific units requires recalled results to include correct units and parameter attributes. This avoids invalid content with mismatched units. Documents with varying update frequencies require the retrieval link to support filtering by release time. This ensures returned financial report data comes from the latest cycle.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Aerospace equipment financial reports contain long sentences with professional parameter descriptions. Overly long segments lose contextual association between business segments. Overly short segments split complete expressions of professional terminology |
similarity_threshold | 0.72–0.85 | Professional terminology in the aerospace field has high distinctiveness. A threshold that is too low introduces irrelevant general aerospace industry data. A threshold that is too high misses accurately matched segmented financial report entries |
recall_top_k | Top 8–12 results | A single aerospace equipment financial report covers multiple business segments. Sufficient recall volume is needed to cover associated information across different segments |
rerank_top_n | Top 3–5 results | The reranking step filters redundant recall results. Core business and financial information for aerospace financial reports is concentrated in a small number of key paragraphs |
overlap_ratio | 15%–20% | Professional terminology appears across segments at a high rate. An overlap ratio that is too low causes terminology to be split across different segments, preventing accurate matching |
metadata_filter | Enable filtering by "financial report type" and "release time" | Aerospace equipment financial reports are divided into annual reports, quarterly reports, and temporary announcements. Filtering by time and type avoids recalling outdated or non-target category data |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing values.
Three Common Configuration Mistakes
- Symptom: Knowledge base retrieval returns an insufficient number of results, failing to cover all business segments of the financial report. Cause: The
recall_top_kvalue is set too low, failing to cover associated information across multiple segments. - Symptom: Returned content after retrieval does not match the professional parameters specified in the query. For example, a query about low Earth orbit carrying capacity returns R&D investment data. Cause: The
metadata_filterfor filtering by financial report segment is not enabled, or thechunk_sizeis set too short, causing professional terminology to be split across different segments. - Symptom: Recalled results include general aerospace industry data from non-target enterprises, and do not match the specified equipment enterprise financial report content. Cause: The
similarity_thresholdis set too low, failing to filter irrelevant entries with low matching accuracy.
How to Verify Correct Configuration
- Upload a single sample aerospace equipment financial report, view the segmented text blocks, confirm that professional terminology is not overly split.
- Enter a specified financial report query, verify that the release time of the recalled results matches the target financial report cycle.
- Adjust the
similarity_threshold, compare changes in the matching degree of recalled results, confirm alignment with business requirements. - After triggering retrieval, check that the field units of returned results match the query requirements, such as including correct units like "tons" or "ten thousand yuan".
