鸿蒙AI实战：Natural Language Kit实现合同语义深度分析
在合同审查场景中，我们基于Natural Language Kit实现专业级语义理解，核心实现代码如下：typescript
// 1. 法律文本特征工程
const nlpEngine = await nlkit.createEngine({
configurations: {
language: 'zh-CN',
domain: 'legal',
features: [
nlkit.FeatureType.ENTITY_RECOGNITION,
nlkit.FeatureType.RELATION_EXTRACTION,
nlkit.FeatureType.SENTIMENT_ANALYSIS
],
modelBundle: 'models/legal_nlp.om'
}
})
// 2. 合同条款智能解析
const analysisResults = await nlpEngine.analyzeContract({
text: contractContent,
params: {
detectRisks: true,
highlightClauses: [
'liability',
'confidentiality',
'termination'
],
compareWith: standardClauses,
},
callback: (progress) => updateAnalysisProgress(progress)
})
// 3. 霸王条款检测
const unfairTermDetector = new nlkit.UnfairTermDetector({
threshold: 0.85,
patterns: await loadUnfairPatterns()
})
const unfairTerms = unfairTermDetector.detect(
analysisResults.sentences
)
// 4. 自动摘要生成
const summarizer = await nlkit.createSummarizer({
style: 'legal',
ratio: 0.2,
constraints: [
'include_parties',
'keep_obligations'
]
})
const summary = summarizer.generate(
contractContent,
{ highlightRisks: true }
)
// 5. 多维度报告生成
const reportBuilder = new nlkit.ReportBuilder({
analysis: analysisResults,
unfairTerms: unfairTerms,
summary: summary,
format: 'markdown'
})
ui.displayReport(reportBuilder.build())
//关键技术组件：
//法律实体识别增强：
typescript
nlpEngine.registerCustomEntities({
'PARTY_A': { patterns: ['甲方', '许可方'] },
'EFFECTIVE_DATE': { regex: '\\d{4}年\\d{1,2}月\\d{1,2}日' }
})
//条款关系图谱：
typescript
const graphBuilder = new nlkit.RelationGraph({
maxDepth: 3,
visualize: true
})
//多语言混合处理：
typescript
const mixedLanguageParser = new nlkit.MixedLanguageParser({
primaryLang: 'zh',
secondaryLang: 'en',
switchThreshold: 0.3
})
//区块链存证：
typescript
const blockchain = new nlkit.BlockchainNotarizer({
chain: 'Hyperledger',
onCommit: (hash) => storeAuditProof(hash)
})
//版本差异比对：
typescript
const diffEngine = new nlkit.VersionComparator({
granularity: 'clause',
highlightChanges: true
})
//智能修订建议：
typescript
const redliner = new nlkit.LegalRedliner({
complianceRules: await loadRegulations(),
suggestionStyle: 'track_changes'
})
//部署最佳实践：
//隐私保护处理：
typescript
nlpEngine.enablePrivacyProtection({
anonymize: ['IDCARD', 'PHONE'],
replacement: '****'
})
//实时资源监控：
typescript
nlkit.monitorPerformance({
samplingRate: 0.1,
alertThreshold: {
cpu: 80,
memory: 4096 // MB
}
})
典型业务场景：
合同风险智能扫描
条款合规自动审查
法律实体关系挖掘
非标条款预警
