How to Establish an AI Analyst with Bag of Words (BoW)

Large volumes of structured data in their databases are among the most critical assets of data-driven organizations. But the real problem is extracting meaningful and actionable insights quickly from them.

It is a common myth that deploying AI-powered analytics takes months of engineering effort. But in reality, with the right tools and processes, you can easily deploy an “AI Analyst” that can answer business questions in natural language in just minutes.

Bag of Words, an open-source platform, makes this possible by connecting any large language models to your structured data sources and helping you query your data in natural conversations without custom code.

So, let us dive deeper and understand how the Bag of Words works, how to set it up, and how you can integrate it into your business workflows to obtain trustworthy and explainable AI analytics.

Understanding Bag of Words

Despite the name, Bag of Words (BoW) is more than just a classic Natural Language Processing (NLP) feature-extraction technique. In this context, Bag of Words refers to an analytics and AI data layer platform that serves as a bridge between databases like SQL databases, warehouses, etc., and LLMs. This platform helps LLM to understand and query structured data and provide context, permissions, and ability to audit.

The platform gives LLM access only to permitted tables/views and enhances the context of data through metadata from BI tools, models, or code, and also ensures governance, audit logs, and control.

In short, BoW here works as a middleware layer that converts structured data and metadata into a context that LLMs can consume and analyze.

Why Use ‘Bag of Words’ for an AI Analyst?

Bag of Words is an excellent choice for data science professionals to deploy an AI analyst. Here are a few reasons to support this:

• Rapid deployment: This platform allows setup and running of an AI analyst in minutes, which significantly reduces time to value compared as compared to building it from scratch
• Flexibility and portability: Bag of Words also supports a lot of data sources, including PostgreSQL, Snowflake, MySQL, cloud data warehouses, and more. It can also work with any compatible LLM.
• Explainability and governance: BoW maintains a clear context on what AI can access, definitions, business logic, etc., and the results provided by AI Analyst are mostly traceable
• Lower engineering overhead: The integration does not require heavy custom integration code or complex ETL/Pipelines. Data science professionals can use containerized deployment, such as Docker and configuration through BoW, to deploy powerful analytics tools.

4-Steps Deployment of an AI Analyst with ‘Bag of Words’

Now, organizations that want to stay ahead in a data-driven world must consider deploying an AI Analyst. Here is a step-by-step process for the same.

Step 1: Prepare your Data Infrastructure

• Ensure your environment is ready using containerization via Docker. Then, run the command:

  docker run --pull always -d -p 3000:3000 bagofwords/bagofwords

  This will initiate a BoW instance on your local or server environment.

  • Have credentials ready for your SQL database (host, port, credentials). BoW supports a wide variety of databases and data warehouses
  • Identify which schemas, tables, and views contain the data you want your AI analyst to access.

Step 2: Provide Context – Metadata, Business Logic, and Permissions

• Defining which tables/views the AI can access is an important part of the setup process. Along with it provide any metadata such as business definitions, data types, column descriptions, etc. that will help AI give correct and meaningful answers.

  You can do this context enhancement through BI tools like Tableau, data modeling tools like dbt, docs, and code repositories.

• Context-aware design helps avoid hallucinations and incorrect interpretations by the LLM.

Step 3: Interact – Query with Natural Language, Get Structured Reports

• Once the setup is complete, you can start asking natural-language questions like “what were our total sales in the last quarter?”, “Which product had the highest returns?”, or “show top 10 customers by revenue”. BoW helps convert these queries and executes them on your database to show the results.
• Data science professionals can also refine their prompts, adjust context and metadata, and iterate to obtain desired results.

Step 4: Deploy and Scale – Integrate into Business Workflows

• When you have validated that queries are working correctly, you can embed the AI analyst into dashboards or other analytics apps through APIs and UI embedding
• Simultaneously, monitor usage, performance, query latencies, and user feedback. With growing adoption, you will need to expand database access and model configurations.

Understanding Limitations and Challenges (and Handling Them)

No system is fully magical. Though Bag of Words makes deployment of an AI Analyst simple, there are some challenges to consider, particularly when integrating it with LLM.

• Data context dependency

  The quality of insights is directly dependent on how well data science professionals define metadata, business logic, and context. So, poor metadata can lead to inaccurate outputs/results.

• Security, access control, and data governance

  As you will give LLMs access to production data, you must ensure permissions, data privacy, and auditing. Thankfully, BoW comes with governance features; however, you need to configure them correctly.

• Model limitations of LLMs

  Some LLMs might not be able to interpret your prompts and metadata properly, leading to generated SQL or data queries being incorrect. That’s why prompt refinement, testing, and prompting engineering are also important in this context.

• Performance

  For very large datasets or complex queries, the entire process of translation, execution, and response generation can be slower.

When to Use Bag of Words?

Here are some of the best use cases of the Bag of Words AI data layer platform for deploying an AI Analyst, when:

• You want fast, conversational analytics for business users so that they can use natural language questions instead of writing SQL
• You already have structured data in your databases and want to leverage AI without building a custom pipeline
• You want explainable and auditable analytics where each result can be traced back
• You want to iterate quickly, refine context, and evolve business logic over time without heavy engineering.

Enterprises can deploy AI analysts with Bag of Words for:

• Sales and revenue reporting
• Customer segmentation
• Support ticket analysis
• Operational dashboards
• Trend tracking, and more

Best Practices for Long-Term Success

If you want your AI Analyst to be useful and reliable, follow these:

• Maintain a clean and well-documented metadata
• Use proper access controls and governance. Restrict what data the AI can access, implement role-based permissions, and log queries
• Test and refine prompts and metadata according to user feedback and real-world usage
• Monitor performance and scale infrastructure, like optimizing the database, caching, or queuing queries as needed
• Have a plan for evolution, like how to update metadata when data volume grows or schema changes. Consider combining BoW with more advanced techniques if required.

Conclusion

Organizations can truly transform the way they interact with data by deploying an AI analyst with Bag of Words. Data professionals can connect their structured data warehouse to a powerful LLM within minutes instead of months of engineering and complex pipelines, and enrich it with context and business logic to power natural language and conversational analytics.

Ultimately, it will help with faster insights, wider accessibility across teams, and explainable AI-driven decision-making.
