To address this, **Retrieval Augmented Generation (RAG)** is used, retrieving relevant external data to supplement the model’s understanding. The effectiveness of RAG relies heavily on the performance of the **embedding model**. ![](https://framerusercontent.com/images/LGDZqKQpkyg5o3n8RWDvpimA.png?width=2048&height=1200) At Linq, we began by addressing these challenges with **Linq-Embed**, which set a new standard in text retrieval. Now, we’ve built upon that success with our latest **finance-specific embedding model**, tailored to meet the specialized demands of financial data. ## **Why a Finance-Specific Model?** General-purpose models often struggle with the complexity of financial documents, which contain specialized jargon, intricate numerical data, and context-specific information. These models are not optimized for financial data, leading to suboptimal results in financial research. ![](https://framerusercontent.com/images/jAy0fjR5gijyP4tpH5IJHYSklFI.png?width=2048&height=1200) Financial analysts require precise, contextually accurate information, and our **finance-specific embedding model, Linq-Embed-Finance,** was developed to address these unique needs. The model ensures that analysts get the exact, relevant, and context-rich data they need to make informed decisions by: - **Understanding Financial Terminology:** Being trained on specialized financial jargon and industry-specific language for accurate retrieval. - **Handling Complex and Numeric Data:** Specializing in processing data formats like tables and figures, essential in financial analysis. - **Optimizing Retrieval for Financial Documents:** Ensuring precision across a wide array of financial sources, such as earnings reports, public filings, and financial statements. Built with **extensive use of financial data**, the model’s embedding dimensions were **fine-tuned to better capture the intricate relationships and subtleties within financial data**. Advanced **synthetic data generation** and **data refinement techniques**—such as data crafting, filtering, and negative mining—enhanced the model's ability to filter out misleading documents and focus on task-specific data. These methods allowed the model to accurately capture the complex relationships within financial documents, greatly improving its performance. ## **Quantitative Evaluation: Focused on Finance** We evaluated **Linq-Embed-Finance** on a range of datasets representing real-world financial research tasks, including retrieving data from 10-K filings, answering questions over earnings reports, and handling multi-hop queries in annual reports. 1. **FinQA |** Earnings reports question-answering 2. **ConvFinQA |** Conversational queries over earnings reports 3. **TATQA |** Hybrid tabular and text queries over financial reports 4. **MultiHeiTT |** Multi-hop queries over annual reports 5. **FinDER |** Passage retrieval from 10-K reports 6. **FinanceBench |** Natural queries over public filings 7. **FinQABench |** Query-based retrieval from 10-K reports ## **Performance Comparison** **Linq-Embed-Finance** was benchmarked against competitors, including **Voyage-Finance**, and consistently outperformed them in terms of precision and retrieval accuracy across all datasets. ![](https://framerusercontent.com/images/Bi95dKR0eZ9F6cB87fk4Pb3BQ.png?width=2048&height=1200) We compared the performance of **Linq-Embed-Finance**, a **domain-specific model** built specifically for financial data, with several **general-purpose embedding models** like **Linq-Embed**, **OpenAI's text-embedding-3-large**, and **Cohere's embed-english-v3.0**, which are designed for more generalized tasks. Additionally, **Voyage Finance 2** is another domain-specific model focused on financial data. - In **FinQA**, Linq-Embed-Finance achieved a score of **55.9**, surpassing **Voyage Finance** (54.2) and showing nearly double the performance of **OpenAI** (27.6). - In **ConvFinQA**, Linq-Embed-Finance scored **57.6**, slightly outperforming **Voyage Finance** (56.9) and significantly surpassing **OpenAI** (34.7). - For table-based queries in **TATQA**, the model reached **56.2**, demonstrating its ability to accurately process both textual and tabular data, compared to **Voyage Finance** (45.8) and **OpenAI** (35.7). - In complex multi-hop queries such as **MultiHeirTT**, **Linq-Embed-Finance** achieved a score of **17.4**, compared to **Voyage Finance** (12.3) and **OpenAI** (3.6). - For general document retrieval tasks, Linq-Embed-Finance also excelled, scoring **62.8** in **FinDER** and **91.4** in **FinQABench**, highlighting its superior ability to handle large-scale financial data. Linq-Embed-Finance demonstrated significant improvements, particularly in **multi-step queries** and **financial document searches**, consistently showing **20-30%** performance gains in precision and accuracy over general-purpose models. This is especially noticeable in tasks requiring the retrieval of highly specific financial information from vast datasets, like **earnings reports spanning multiple fiscal years**. ## **Conclusion: Search Tailored for Large-Scale Financial Data** **Linq-Embed-Finance** enables analysts to perform accurate searches across vast amounts of financial data. Whether dealing with **earnings reports spanning multiple fiscal years** or **complex filings** from hundreds of companies, RAG ensures that the most relevant information is retrieved, allowing for deeper insights that general-purpose models miss. In our next post, we’ll explore how **Linq Alpha’s Three Guardrails**—trusted data, evaluation agents, and interactive validation—work together to ensure AI-generated outputs are not only accurate but also actionable and trustworthy. _👉 To experience how Linq’s tailored search solutions can enhance your financial research, please_ [_contact sales_](https://linqalpha.com/contact-sales)_._ ## Linq-Embed-Finance: Bridging the Last Mile of Accuracy in Search Large Language Models (LLMs) have inherent limitations due to their restricted **context token window**, making it challenging to process thousands of documents effectively.
