鸿蒙AI开发实战：HiAI Foundation Kit打造智能合同审核系统
在合同文档处理场景中，我们基于HiAI Foundation Kit实现AI智能分析，完整实现代码如下：typescript
// 1. 模型初始化与加载
const contractModel = await hiAI.loadModel({
modelPath: 'models/contract_analysis.om',
framework: hiAI.Framework.TENSORFLOW_LITE,
device: hiAI.Device.NPU,
config: {
performanceMode: hiAI.PerformanceMode.HIGH,
priority: hiAI.Priority.HIGH
}
})
// 2. 合同风险智能分析
const analysisResults = await contractModel.infer({
input: documentText,
params: {
riskThreshold: 0.75,
detectTypes: [
'UNFAIR_CLAUSE',
'LIMITED_LIABILITY',
'AUTO_RENEWAL'
],
language: 'zh'
},
onProgress: (p) => updateAIAnalysisProgress(p)
})
// 3. 关键条款比对
const clauseComparator = new hiAI.ClauseComparator({
standardClauses: await loadStandardClauses(),
similarityThreshold: 0.85
})
const deviationReport = clauseComparator.compare(
analysisResults.detectedClauses
)
// 4. 智能修正建议
const revisionEngine = await hiAI.createTextGenerator({
model: 'contract_revision',
style: 'LEGAL',
constraints: [
'COMPLIANCE',
'BALANCED_RIGHTS'
]
})
const suggestions = await revisionEngine.generate(
analysisResults.riskClauses
)
// 5. 结果可视化
const reportBuilder = new ContractReport({
risks: analysisResults,
deviations: deviationReport,
suggestions: suggestions
})
canvas.draw(reportBuilder.generateVisualization())
核心技术组件：
//混合精度计算：
typescript
hiAI.setPrecision({
model: contractModel,
input: hiAI.Precision.FP16,
output: hiAI.Precision.FP32
})
//实时模型更新：
typescript
const modelUpdater = new hiAI.ModelUpdater({
checkInterval: 3600,
onUpdate: (newModel) => {
contractModel.switchModel(newModel)
}
})
//多模型协同：
typescript
const ensembleResults = await hiAI.ModelEnsemble.run([
{ model: 'clause_detection', weight: 0.6 },
{ model: 'risk_assessment', weight: 0.4 }
], documentText)
//区块链存证：
typescript
const blockchain = new hiAI.BlockchainIntegrator({
chain: 'Hyperledger',
onVerify: (hash) => storeAuditTrail(hash)
})
//多模态分析：
typescript
const multiModalAnalyzer = new hiAI.MultiModalAnalyzer({
text: contractText,
signatures: signatureImages,
stamps: sealImages
})
//风险预测：
typescript
const riskPredictor = await hiAI.loadTimeSeriesModel({
path: 'models/risk_prediction.om',
lookbackWindow: 30 // 天
})
