Data Characteristics
Blood glucose data originates from personal glucometers, continuous glucose monitoring (CGM) devices, and some smart wearables. These devices update data frequently. CGM devices, in particular, collect data at minute or even second intervals, forming continuous time series. Data documents typically include a timestamp, blood glucose value (mg/dL or mmol/L), and event markers (e.g., pre-meal, post-meal, exercise, medication). Some devices also record accompanying information such as insulin dosage, dietary intake, and exercise duration. Field names and units show a trend toward standardization, for example, glucose_level and timestamp. However, device output formats and field naming still vary across manufacturers. Formats may include CSV, JSON, or proprietary binary formats.
Constraints from Data Characteristics on Forms and Interaction
High-frequency updates and time-series data require form designs that efficiently handle bulk data uploads and real-time data stream integration. Diverse data formats necessitate flexible data import options, such as file uploads or API credential input. Capturing event markers and accompanying information means forms need structured input fields. These fields help users provide context, which improves interpretation accuracy. International differences in blood glucose units (mg/dL and mmol/L) require clear unit selection or automatic recognition mechanisms in the interaction to prevent misinterpretation due to unit confusion. Data privacy and sensitivity dictate strict adherence to data security and compliance requirements during form submission and data processing.
Configuration Guidelines
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 10 MB | Accommodates typical blood glucose data file sizes for a single user. Prevents upload failures or memory exhaustion due to excessively large files. |
maxContext | 3000 Tokens | Ensures enough capacity for recent blood glucose data and necessary contextual information for a complete interpretation. |
PARSE_FILE_TIMEOUT_SECONDS | 60 seconds | Allows sufficient time to parse blood glucose data files of various formats. Prevents parsing timeouts due to file complexity or network latency. |
similarityThreshold | 0.75 | Matches specific blood glucose events or user queries with relevant interpretation rules in the knowledge base. |
segmentLength | 800 characters | Segments longer blood glucose trend analysis reports or health recommendations. This facilitates model processing and user readability. |
modelTemperature | 0.3 | Ensures the rigor and consistency of blood glucose interpretation results. Prevents overly divergent or inaccurate recommendations. |
Common Pitfalls
- After data upload, the smart customer service returns "data format error" or "unrecognized fields." This occurs when the system does not adequately cover the data formats and field naming conventions exported by different blood glucose devices, preventing the parser from correctly extracting key information.
- A user submits continuous blood glucose data, but the system only interprets a partial time period or a single value. This happens when the
maxContextparameter is set too low, failing to accommodate the complete historical data. This leads to truncation or processing only of the latest data. - A user inputs information like "insulin dosage," but the system fails to associate it with blood glucose interpretation. This is due to form design that does not provide corresponding structured fields or prompts. Users then input information as free text, making it difficult for the model to accurately capture and use as context.
Verification Steps
- Upload real data files from different brands of glucometers and CGM devices. Check if the system correctly parses and extracts all key fields and values.
- Submit forms containing high-frequency, long-period blood glucose data. Verify if the smart customer service provides coherent trend analysis and interpretation based on the complete data.
- Intentionally input blood glucose values in different units (e.g.,
120 mg/dLand6.7 mmol/L) into the form. Confirm if the system correctly identifies and converts units or prompts the user to select a unit. - Simulate user questions about specific scenarios, such as post-meal blood glucose or post-exercise blood glucose, and provide relevant accompanying information. Check if the smart customer service provides personalized interpretations based on this information.
