Three Steps to Setup a Generation Project


In today’s rapidly evolving digital landscape, content creation has become more crucial than ever for brands to engage their audiences. With the emergence of large language models (LLMs) such as ChatGPT and GPT4, natural language processing and artificial intelligence have seen revolutionary advances. While excelling in creative content generation, LLMs face some limitations. A key challenge lies in their ability to access and integrate factual knowledge, real world experiences and above all the brand’s core values. In addition, LLMs can sometimes produce output with hallucinated or fictitious elements, adding a layer of complexity. 

Knowledge Graphs (KGs) are crucial to overcoming limitations. They host structured, factual data and provide a solid foundation for training LLMs, ensuring that content is articulated and grounded in reliable information. This synergy represents a substantial step towards more authoritative content driven by artificial intelligence.

In addition, the knowledge graph enhances structured data, refining assumptions about content by infusing brand values into the model. Using an ontology for your brand, product-specific traits can be amplified. For example, when it comes to RayBan, specific materials take precedence. This goes beyond fact-checking by formalizing and operationalizing domain-specific insights.

This emphasizes the central role of ontology, making it clear that semantic data has a sophisticated purpose beyond mere fact-checking.

In this context, we have created a solution for SEOs and content marketers, enabling editorial teams to scale content production while maintaining maximum control over quality and relevance.

Whether product descriptions, restaurant profiles, or introductory text for category pages, our tool delivers reliable results. In this article, we introduce you to our Content Creation Tool and explain why it is so ahead of other AI content creation tools. 

Advantages of Complementing Large Language Models (LLMs) with Knowledge Graphs (KGs)

The synergy between LLMs and KGs can significantly enhance the capabilities of content generation systems, making them more accurate, reliable, and adaptable to a wide range of applications and industries. By integrating KGs with LLMs, we can leverage the advantages of both technologies. 

Indeed, integrating Knowledge Graphs into Large Language Models can help overcome some of the limitations and challenges of using Large Language Models alone, such as:

Lack of factual knowledge and consistency, such as making errors or contradictions when dealing with factual information or common sense knowledge;

Lack of interpretability and explainability, such as being unable to provide the source or justification of the generated outputs or decisions; 

Lack of efficiency and scalability, such as requiring large amounts of data and computational resources to train and fine-tune the models for different tasks or domains.

One way to combine Knowledge Graphs and Large Language Models is to use the Knowledge Graph as a source of external knowledge for the Large Language Model so that it can answer questions or generate texts that require factual information. For example, suppose you ask a Large Language Model to write a biography of Leonardo da Vinci. In that case, it can use the Knowledge Graph to retrieve facts about his life, such as his birth date, occupation, inventions, artworks, etc., and use them to write a coherent and accurate text. This way, the Large Language Model can leverage the structured and rich knowledge of the Knowledge Graph to enhance its inference and interpretability.

This synergy between LLM and KG opens up new possibilities for content generation and reasoning, such as:

It generates more informative, diverse, and coherent texts incorporating relevant KG knowledge, such as facts, entities, relationships, etc.

It generates more personalized and engaging texts that adapt to user preferences, interests, and goals, which KGs can shape.

It generates more creative and novel texts that explore new combinations of knowledge from KGs, such as stories, poems, jokes, etc.

It can store newly generated content and effectively re-use archival content. A KG acts as a long-term memory and helps us differentiate the content we produce.

LLMs and KGs can work together to enhance various content-generation applications. For instance, in question answering, they can generate accurate, concise, and comprehensive answers by using information from KGs in conjunction with context from LLMs. In dialogue systems, they can produce relevant, consistent, and informative responses by leveraging dialogue history from LLMs along with user profiles from KGs. Additionally, they can generate faithful, concise, and salient summaries fortext summarization by utilizing input text from LLMs alongside key information from KGs. In constructing AI agents in SEO, they can teach how to answer questions instead of predicting similar sentences. 

Keeping the “Human in the Loop” in Scalable Content Production

At WordLift, we advocate the crucial role of human oversight and control, especially when content production reaches thousands of pieces. 

Our approach goes beyond simple automation, focusing on meticulous modeling of the data within the Knowledge Graph (KG) and curating and refining the underlying ontology. By identifying the essential attributes used to generate dynamic prompts, we enable companies to train custom language models to maintain a firm grasp on the quality and relevance of their content while meeting rigorous editorial standards.

Our innovative strategy directly addresses this contentious issue surrounding generative AI and content creation. Furthermore, our KG-centric methodology is a game-changer. It liberates companies from relying on external data, as it ensures that internal sources suffice for robust language model training. This reflects our dedication to sustainability and underscores the ethical use of AI resources

In addition, we uphold the implementation of validation rules, adding an extra layer of assurance for precision and error prevention. This comprehensive approach seamlessly marries the potential of AI with the human touch, culminating in content excellence, fortified editorial control, and eco-conscious practices.

In practice, we’re producing an impressive content volume catering to some of the world’s foremost fashion brands and publishers. The true challenge isn’t merely ramping up content creation but ensuring meticulous validation of each piece. To date, we’re glad to share that we’ve achieved +500 completions per minute.
