meetara-lab/vectorstore-economics

Vectorstore Dataset: Economics

Overview

This dataset contains pre-computed vector embeddings for the economics domain, ready for use in Retrieval-Augmented Generation (RAG) applications, semantic search, and knowledge base systems. The embeddings are generated from high-quality source documents using state-of-the-art sentence transformers, making it easy to build production-ready RAG applications without the computational overhead of embedding generation.

What This Knowledge Base Covers

This knowledge base covers economics concepts, theories, and applications. It includes topics such as microeconomics, macroeconomics, market structures, supply and demand, monetary and fiscal policy, trade, and economic indicators. Use it to answer questions about economic principles, policy analysis, market behavior, and real-world economic phenomena.

Key Features

• ✅ Pre-computed embeddings: Ready-to-use vector embeddings, saving computation time
• ✅ Production-ready: Optimized for real-world RAG applications
• ✅ Comprehensive metadata: Includes source file information, page numbers, and document hashes
• ✅ LangChain compatible: Works seamlessly with LangChain and ChromaDB
• ✅ Search-optimized: Designed for fast semantic similarity search

What's Included

This dataset contains 4,228 text chunks from 3 source documents, each pre-embedded using the sentence-transformers/all-MiniLM-L6-v2 model. Each chunk includes:

• Text content: The original document text
• Embedding vector: 384-dimensional float32 vector
• Rich metadata: Source file, page numbers, document hash, and more

Usage

Loading the Dataset

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("meetara-lab/vectorstore-economics")

# Access the data
print(dataset["train"][0])
# Output:
# {
#     'id': '...',
#     'embedding': array([...], dtype=float32),
#     'document': '...',
#     'metadata': '{"file_name": "...", "page": 1, ...}'
# }

Loading Back into ChromaDB

from langchain_chroma import Chroma
from langchain_huggingface import HuggingFaceEmbeddings
from datasets import load_dataset
import json

# Load dataset
dataset = load_dataset("meetara-lab/vectorstore-economics")["train"]

# Initialize ChromaDB
embeddings = HuggingFaceEmbeddings(model_name="sentence-transformers/all-MiniLM-L6-v2")
vectorstore = Chroma(
    persist_directory="./chroma_economics",
    embedding_function=embeddings
)

# Add documents to ChromaDB
documents = []
metadatas = []
ids = []
embeddings_list = []

for item in dataset:
    ids.append(item["id"])
    embeddings_list.append(item["embedding"].tolist())
    documents.append(item["document"])
    metadatas.append(json.loads(item["metadata"]))

# Note: You'll need to use ChromaDB's Python client directly for custom embeddings
import chromadb
client = chromadb.PersistentClient(path="./chroma_economics")
collection = client.create_collection(name="economics")

collection.add(
    ids=ids,
    embeddings=embeddings_list,
    documents=documents,
    metadatas=metadatas
)

Using with LangChain

from langchain_chroma import Chroma
from langchain_huggingface import HuggingFaceEmbeddings

# Initialize retriever
embeddings = HuggingFaceEmbeddings(model_name="sentence-transformers/all-MiniLM-L6-v2")
vectorstore = Chroma(
    persist_directory="./chroma_economics",
    embedding_function=embeddings
)

# Load from HF Hub first (see above), then use with LangChain
retriever = vectorstore.as_retriever()
results = retriever.invoke("your query here")

Domain-Specific Usage Examples

This vectorstore is optimized for Economics domain queries. Here are practical examples:

Example Queries

from langchain_chroma import Chroma
from langchain_huggingface import HuggingFaceEmbeddings

# Load vectorstore (see "Loading Back into ChromaDB" above)
embeddings = HuggingFaceEmbeddings(model_name="sentence-transformers/all-MiniLM-L6-v2")
vectorstore = Chroma(
    persist_directory="./chroma_economics",
    embedding_function=embeddings
)
retriever = vectorstore.as_retriever(search_kwargs={"k": 3})

# Example queries for economics domain:
example_queries = [
    "What is the law of supply and demand?",
    "Explain inflation and its causes",
    "What are the effects of interest rate changes?",
    "How do markets reach equilibrium?",
    "What is GDP and how is it measured?"
]

# Run a query
query = "What is the law of supply and demand?"
results = retriever.invoke(query)

# Display results
for i, doc in enumerate(results, 1):
    print(f"\nResult {i}:")
    print(f"  Source: {doc.metadata.get('file_name', 'Unknown')}")
    print(f"  Page: {doc.metadata.get('page', 'N/A')}")
    print(f"  Content: {doc.page_content[:200]}...")

Common Use Cases

This dataset is useful for:

• Economics concept explanation and lookup
• Policy analysis and evaluation
• Market behavior and theory reference
• Economic indicators interpretation
• Trade and international economics

Real-World Example

# Complete example: Query and use results
from langchain_chroma import Chroma
from langchain_huggingface import HuggingFaceEmbeddings

# 1. Initialize (after loading from HF Hub)
embeddings = HuggingFaceEmbeddings(model_name="sentence-transformers/all-MiniLM-L6-v2")
vectorstore = Chroma(
    persist_directory="./chroma_economics",
    embedding_function=embeddings
)

# 2. Create retriever with relevance filtering
retriever = vectorstore.as_retriever(
    search_type="similarity",
    search_kwargs={
        "k": 5,  # Get top 5 most relevant results
        "score_threshold": 0.7  # Minimum similarity score
    }
)

# 3. Query the vectorstore
query = "Explain inflation and its causes"
docs = retriever.invoke(query)

# 4. Process results
for doc in docs:
    metadata = doc.metadata
    print(f"📄 File: {metadata.get('file_name', 'Unknown')}")
    print(f"📃 Page: {metadata.get('page', 'N/A')}")
    print(f"📝 Content: {doc.page_content[:300]}...\n")
