In the modern business landscape, organizations face a challenging task - managing an overflow of information. The spread of data across various instances of knowledge management systems, such as Confluence, Jira, and SharePoint - in favorable scenarios and network shares in less optimal situations - can make locating specific pieces of information comparable to finding a needle in a haystack. It is a dilemma we recently identified and resolved for a client in the German automotive industry, offering valuable insights into improving our approach to information management.
The Complexity of Information Management
Our client's organizational structure was complex, with several teams operating across different systems, each with their specific patterns, formalities, and personal nuances in the way they stored and managed information. As such, the challenge was not just technical but also deeply organizational. Aligning the various needs and policies, security guidelines, and more presented a significant hurdle.
Take, for example, Team A who preferred to store their data as Word documents in a SharePoint library, while Team B used Confluence to manage their project documentation. The differences in these systems and their utilization meant that consolidating this information into a single, easily accessible resource was no mean feat.
Building Bridges Across Information Islands
Given the complexity of the task, we implemented a straight forwad approach - Elasticsearch to handle data storage and Azure OpenAI services to manage data retrieval.
Elasticsearch, a robust open-source search and analytics engine, played an important role. Its primary task was the serving and indexing of data. Building multiple specific data pipelines was a prerequisite given the dozens of documentation sources we needed to connect, each with its unique structure and format.
Deploying Elasticsearch presented various challenges. We had to handle tasks like managing cluster size, configuring node types accurately, and ensuring data security. It was crucial to guarantee the strength and resilience of our deployment to avoid any data loss.
Preprocessing the data was another big task. Cleaning and standardizing the data, dealing with missing or inconsistent data, and converting the raw data like HTML, Word documents, and XML into a format that could be easily indexed and searched by Elasticsearch required developing custom applications and using various data preprocessing libraries in Python. One of the significant challenges we faced was ensuring efficient synchronization between different sources without exhausting system resources. For instance, if the AI service is querying data while an update is in progress, it could lead to data inconsistencies and out-of-date data. We navigated this challenge by implementing a queue-based architecture using EventHubs, which ensured updates and queries didn't interfere with each other, maintaining the integrity of the data and the stability of the system.
Post the preprocessing and indexing, the next phase was integrating this with Azure-hosted OpenAI services. Azure AI Studio was useful, providing a user-friendly interface for managing and configuring OpenAI services. The process involved setting up API keys, specifying endpoints, and enabling necessary security measures to ensure data privacy and compliance with regulations.
To create an application and an API for data retrieval, we had to carefully consider factors such as security, scalability, and responsiveness. Azure App Service was our choice, given its automatic scaling feature that allowed the application to handle more significant loads seamlessly and its integrated CI/CD capabilities that streamlined the deployment and update processes.
Tapping into the Power of Natural Language
Instead of a chatbot model, which can often lead to unnecessary back-and-forth, we utilized the capabilities of GPT-4 to interact with our Elasticsearch database. GPT-4 parsed the natural language query, searched for relevant information, and generated a concise summary of relevant documents.
Conclusion
By combining the power of Elasticsearch and Azure OpenAI, we created a system that cut through the information overload, delivering a streamlined, user-friendly way to access information. The development had its challenges, but overcoming them led to a solution that is flexible, robust, and cost-effective. It shows the potential of AI in knowledge management, showing us that no haystack is too large to find the proverbial needle.
