An overview of standard retrieval-augmentation generation framework. Given a user query\/prompt, the typical process consists of two phases: retrieval and content generation.

(2) In the content generation phase, the retrieved texts are passed to the language model, which augment the retrieved texts with its internal training data to synthesize a response to the user\u2019s prompt. <a href=\"https:\/\/research.ibm.com\/blog\/retrieval-augmented-generation-RAG\" target=\"_blank\" rel=\"noopener\">Despite this method proposed as a potential solution to the hallucination problem<\/a> in the generated responses, in practice, we saw that even RAG systems are not hallucination-free, and identified several challenges.<\/figcaption><\/figure><figure id=\"attachment_11236\" aria-describedby=\"caption-attachment-11236\" style=\"width: 1056px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-11236 size-full\" src=\"https:\/\/minicoursegenerator.com\/wp-content\/uploads\/2025\/03\/ss-2.png\" alt=\"\" width=\"1056\" height=\"549\" srcset=\"https:\/\/minicoursegenerator.com\/wp-content\/uploads\/2025\/03\/ss-2.png 1056w, https:\/\/minicoursegenerator.com\/wp-content\/uploads\/2025\/03\/ss-2-300x156.png 300w, https:\/\/minicoursegenerator.com\/wp-content\/uploads\/2025\/03\/ss-2-1024x532.png 1024w, https:\/\/minicoursegenerator.com\/wp-content\/uploads\/2025\/03\/ss-2-768x399.png 768w\" sizes=\"(max-width: 1056px) 100vw, 1056px\" \/><figcaption id=\"caption-attachment-11236\" class=\"wp-caption-text\">Figure 2. The detailed RAG Pipeline with re-ranking was intended to enhance the standard RAG framework by introducing an additional refinement layer between the initial retrieval and generation phases. The re-ranking component was designed to employ a semantic analysis to score and filter retrieved documents based on factors like query-document relevance, content quality, and cross-document coherence. This intermediate layer was meant to serve as a quality control mechanism to ensure only the most relevant and reliable context would reach the language model for response generation. However, in practice, our re-ranking mechanism proved inadequate in properly weighing and prioritizing relevant content. More specifically, the triple challenge of unreliable retrieval, limited semantic understanding, and ineffective re-ranking created conditions where the LLM must generate responses with inadequate or misaligned information, leading to increased likelihood of hallucinations in the output.<\/figcaption><\/figure><p><span style=\"font-weight: 400;\">To be more specific, in our implementation, we encountered several significant technical challenges that highlighted the limitations of our <\/span><i style=\"font-size: 16px;\">RAG<\/i><span style=\"font-weight: 400;\"> pipeline<\/span><i style=\"font-size: 16px;\">, <\/i><span style=\"font-weight: 400;\">typically due to the<\/span><i style=\"font-size: 16px;\"> steps <\/i><span style=\"font-weight: 400;\">in between the retrieval and augmentation:<\/span><\/p><ol><li style=\"font-weight: 400;\" aria-level=\"1\"><i><span style=\"font-weight: 400;\">Vector database retrieval problems<\/span><\/i><span style=\"font-weight: 400;\">: Our initial experiments revealed significant challenges in the foundational retrieval phase, where the vector database consistently failed to retrieve contextually appropriate texts. Despite our best efforts at optimization, the semantic similarity scores were not reliably identifying the most relevant content, forcing the system to work with incomplete or inappropriate context. This fundamental retrieval issue significantly increased the risk of <\/span><i><span style=\"font-weight: 400;\">hallucinations<\/span><\/i><span style=\"font-weight: 400;\"> in the generated responses.<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><i><span style=\"font-weight: 400;\">Semantic relationship limitations<\/span><\/i><span style=\"font-weight: 400;\">: The root cause of these retrieval problems became clear as we discovered that relying on numerical representations (i.e., vectors) for semantic understanding was insufficient for capturing nuanced conceptual relationships, leading to misinterpretations and incorrect inferences in the generated responses.<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><i><span style=\"font-weight: 400;\">Re-ranking issues<\/span><\/i><span style=\"font-weight: 400;\">: Our re-ranking mechanisms proved inadequate in properly weighing and prioritizing relevant content, leading to suboptimal content selection and organization.

Beginning with a review of both industry stakeholder experiences and current research on factual consistency verification, we identified several solutions to tackle the <\/span><i><span style=\"font-weight: 400;\">hallucination<\/span><\/i><span style=\"font-weight: 400;\"> problem. Though there has not been a consensus on a crystal clear solution, we observed the feasibility of comparing generated text against its source material for similarity assessment. Although perfect fact-checking would require deep semantic understanding, we determined that additionally quantifying the alignment between generated text and its source could provide a proxy for factual consistency for our users, leading us to implement a systematic text comparison approach that converts textual information into numerical representations, enabling us to generate a factual consistency score as an automated measure of content fidelity to its source.<\/span><\/p><p><span style=\"font-weight: 400;\">Our solution implemented this approach through three key steps:<\/span><\/p><ol><li style=\"font-weight: 400;\" aria-level=\"1\"><b>Text cleaning<\/b><span style=\"font-weight: 400;\">, which prepares the content by removing stop-words (common words like \u201cthe,\u201d \u201cis,\u201d&#8221; \u201cat,\u201d and \u201cwhich\u201d that carry little semantic meaning) and formatting inconsistencies (such as inconsistent capitalization, punctuation, and extra whitespace) to ensure meaningful comparison focuses on content-carrying terms.\u00a0<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><b>Semantic encoding<\/b><span style=\"font-weight: 400;\">, which employs<\/span> <a href=\"https:\/\/spacy.io\/\"><span style=\"font-weight: 400;\">spaCy<\/span><\/a><span style=\"font-weight: 400;\">\u2019s (an open-source natural language processing library) language model to transform the cleaned text into numerical representations to enable a mathematical comparison of textual content.<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><b>Similarity assessment<\/b><span style=\"font-weight: 400;\">, which applies cosine similarity calculations (a mathematical measure that determines how similar two vectors are by calculating the cosine of the angle between them, resulting in a score between 0 and 1, where 1 indicates perfect similarity) to quantify the alignment between source and generated content.<\/span><\/li><\/ol><p><span style=\"font-weight: 400;\"><br \/>By leveraging natural language processing techniques, we targeted identifying semantic similarities even when different vocabulary or phrasing is used. As an illustrative example, consider a source text about the Renaissance period and its AI-generated explanation (see <\/span><i><span style=\"font-weight: 400;\">Figure 4<\/span><\/i><span style=\"font-weight: 400;\">). The method can recognize semantic alignment despite variations in phrasing (such as \u201ccultural rebirth\u201d versus \u201ccultural revival\u201d and \u201cclassical art\u201d versus \u201cancient Greek and Roman works\u201d), while still identifying potential factual inconsistencies.

This integrated solution enables us to measure semantic similarity across diverse content types while maintaining closer control over content retrieval and generation.<\/span><\/p><p><span style=\"font-weight: 400;\">While our initial test results demonstrate measurable improvements in content accuracy, we acknowledge that this represents only the beginning of our efforts to enhance AI-generated content reliability. Our commitment to delivering accurate, trustworthy learning materials drives us to continuously evaluate and refine our approach, maintaining transparency about its current limitations. As we continue developing our methods, we value constructive feedback that helps improve both our technical implementation and our accountability to the educational communities we learn and grow with. And, this dedication to reliable knowledge creation remains central to our ongoing development of AI-assisted learning content generation.<\/span><\/p><p><b>References<\/b><\/p><p><span style=\"font-weight: 400;\">Anthropic.
