9.2 Detailed Task Implementation

Task 1: Text Summarization

Model: facebook/bart-large-cnn

Purpose: Condense long research documents into concise summaries

Implementation:

// src/lib/ai/summarization.service.ts
import { HfInference } from '@huggingface/inference';

export class SummarizationService {
  private hf: HfInference;

  constructor() {
    this.hf = new HfInference(process.env.HUGGINGFACE_API_KEY);
  }

  async summarizeDocument(text: string, maxLength = 150): Promise<string> {
    // Check cache first
    const cacheKey = `summary:${hashText(text)}:${maxLength}`;
    const cached = await redis.get(cacheKey);
    if (cached) return cached;

    // Call HuggingFace API
    const response = await this.hf.summarization({
      model: 'facebook/bart-large-cnn',
      inputs: text,
      parameters: {
        max_length: maxLength,
        min_length: Math.floor(maxLength / 3),
        do_sample: false,
      },
    });

    const summary = response.summary_text;

    // Cache for 24 hours
    await redis.setex(cacheKey, 86400, summary);

    return summary;
  }

  async summarizeMultipleDocuments(
    documents: string[]
  ): Promise<string> {
    // Summarize each document
    const summaries = await Promise.all(
      documents.map((doc) => this.summarizeDocument(doc, 100))
    );

    // Combine and summarize again
    const combined = summaries.join('\n\n');
    return await this.summarizeDocument(combined, 300);
  }
}

Usage in Research Flow:

// After gathering sources
const summaries = await summarizationService.summarizeMultipleDocuments(
  sources.map((s) => s.content)
);

Task 2: Named Entity Recognition (NER)

Model: dslim/bert-base-NER

Purpose: Extract people, organizations, locations from research

Implementation:

// src/lib/ai/ner.service.ts
export class NERService {
  async extractEntities(text: string): Promise<Entity[]> {
    const response = await this.hf.tokenClassification({
      model: 'dslim/bert-base-NER',
      inputs: text,
    });

    // Group consecutive tokens
    const entities = this.groupEntities(response);

    // Store in knowledge graph
    await this.storeInKnowledgeGraph(entities);

    return entities;
  }

  private groupEntities(tokens: any[]): Entity[] {
    const entities: Entity[] = [];
    let current: Entity | null = null;

    for (const token of tokens) {
      const type = token.entity_group;
      const word = token.word;

      if (current && current.type === type) {
        // Continue existing entity
        current.text += word.startsWith('##') ? word.slice(2) : ' ' + word;
        current.score = Math.max(current.score, token.score);
      } else {
        // Start new entity
        if (current) entities.push(current);
        current = {
          text: word,
          type,
          score: token.score,
        };
      }
    }

    if (current) entities.push(current);

    return entities.filter((e) => e.score > 0.8); // High confidence only
  }

  private async storeInKnowledgeGraph(entities: Entity[]) {
    for (const entity of entities) {
      await neo4j.run(
        `
        MERGE (e:Entity {name: $name, type: $type})
        ON CREATE SET e.first_seen = timestamp()
        ON MATCH SET e.last_seen = timestamp(), e.frequency = e.frequency + 1
      `,
        { name: entity.text, type: entity.type }
      );
    }
  }
}

Task 3: Sentiment Analysis

Model: distilbert-base-uncased-finetuned-sst-2-english

Purpose: Analyze sentiment of sources for bias detection

Implementation:

// src/lib/ai/sentiment.service.ts
export class SentimentService {
  async analyzeSentiment(text: string): Promise<SentimentResult> {
    const response = await this.hf.textClassification({
      model: 'distilbert-base-uncased-finetuned-sst-2-english',
      inputs: text,
    });

    const sentiment = response[0];

    return {
      label: sentiment.label, // POSITIVE or NEGATIVE
      score: sentiment.score,
      interpretation: this.interpretSentiment(sentiment.score, sentiment.label),
    };
  }

  async analyzeSources(sources: Source[]): Promise<SourceSentiment[]> {
    const results = await Promise.all(
      sources.map(async (source) => ({
        sourceId: source.id,
        sentiment: await this.analyzeSentiment(source.content),
      }))
    );

    // Detect bias
    const bias = this.detectBias(results);

    return results.map((r) => ({
      ...r,
      biasWarning: bias.outliers.includes(r.sourceId),
    }));
  }

  private detectBias(results: any[]): { outliers: string[] } {
    const scores = results.map((r) =>
      r.sentiment.label === 'POSITIVE' ? r.sentiment.score : -r.sentiment.score
    );

    const mean = scores.reduce((a, b) => a + b) / scores.length;
    const stdDev = Math.sqrt(
      scores.map((x) => Math.pow(x - mean, 2)).reduce((a, b) => a + b) /
        scores.length
    );

    // Flag outliers (>2 std devs from mean)
    const outliers = results
      .filter((r, i) => Math.abs(scores[i] - mean) > 2 * stdDev)
      .map((r) => r.sourceId);

    return { outliers };
  }
}

Task 4: Question Answering

Model: deepset/roberta-base-squad2

Purpose: Extract specific answers from research documents

Implementation:

// src/lib/ai/qa.service.ts
export class QuestionAnsweringService {
  async answerQuestion(
    question: string,
    context: string
  ): Promise<AnswerResult> {
    const response = await this.hf.questionAnswering({
      model: 'deepset/roberta-base-squad2',
      inputs: {
        question,
        context,
      },
    });

    return {
      answer: response.answer,
      score: response.score,
      start: response.start,
      end: response.end,
      context: context.substring(
        Math.max(0, response.start - 100),
        Math.min(context.length, response.end + 100)
      ),
    };
  }

  async answerFromMultipleSources(
    question: string,
    sources: Source[]
  ): Promise<AnswerResult[]> {
    const answers = await Promise.all(
      sources.map((source) =>
        this.answerQuestion(question, source.content).catch(() => null)
      )
    );

    return answers
      .filter((a) => a !== null && a.score > 0.5)
      .sort((a, b) => b.score - a.score);
  }
}

Task 5: Text Embeddings

Model: sentence-transformers/all-MiniLM-L6-v2

Purpose: Generate embeddings for semantic search

Implementation:

// src/lib/ai/embeddings.service.ts
export class EmbeddingsService {
  async generateEmbedding(text: string): Promise<number[]> {
    // Check cache
    const cacheKey = `embedding:${hashText(text)}`;
    const cached = await redis.get(cacheKey);
    if (cached) return JSON.parse(cached);

    // Generate embedding
    const response = await this.hf.featureExtraction({
      model: 'sentence-transformers/all-MiniLM-L6-v2',
      inputs: text,
    });

    const embedding = Array.from(response as number[]);

    // Cache permanently (embeddings don't change)
    await redis.set(cacheKey, JSON.stringify(embedding));

    return embedding;
  }

  async indexDocument(doc: Document) {
    const embedding = await this.generateEmbedding(doc.content);

    // Store in AgentDB
    await agentdb.insert({
      id: doc.id,
      vector: embedding,
      metadata: {
        title: doc.title,

9.3 Cost Optimization for HuggingFace

Strategy:

  1. Aggressive Caching - Cache all API responses with appropriate TTL
  2. Local Inference - Use Transformers.js for simple tasks in browser
  3. Batch Processing - Combine multiple requests where possible
  4. Model Selection - Use smaller models for non-critical tasks
  5. Rate Limiting - Prevent unnecessary API calls

Cost Calculator:

// src/lib/ai/cost-tracker.ts
export class AIcostTracker {
  async trackUsage(model: string, tokensUsed: number) {
    const cost = this.calculateCost(model, tokensUsed);

    await db.aiUsage.create({
      data: {
        model,
        tokens: tokensUsed,
        cost,
        timestamp: new Date(),
      },
    });

    // Alert if exceeding budget
    const monthlyTotal = await this.getMonthlyTotal();
    if (monthlyTotal > BUDGET_LIMIT) {
      await this.sendBudgetAlert(monthlyTotal);
    }
  }

  private calculateCost(model: string, tokens: number): number {
    const pricing = {
      'facebook/bart-large-cnn': 0.0004, // per 1K tokens
      'dslim/bert-base-NER': 0.0003,
      'distilbert-base-uncased-finetuned-sst-2-english': 0.0002,
      'sentence-transformers/all-MiniLM-L6-v2': 0.0002,
    };

    const pricePerK = pricing[model] || 0.0005;
