Extracting Formulas and Metadata with Anthropic’s Claude
Once the image documents are prepared, Anthropic’s Claude, accessed through the Amazon Bedrock Converse API, is utilized to extract formulas and metadata. Furthermore, the Amazon Bedrock Converse API can be leveraged to generate plain-language explanations of the extracted formulas. This combination of formula and metadata extraction capabilities with conversational AI provides a holistic solution for processing and understanding the information contained within the image documents.
The process begins by sending the image of a page to Claude, along with a prompt requesting the extraction of formulas. Claude’s vision capabilities allow it to analyze the image and identify the formulas present. It then transcribes these formulas into a machine-readable format, such as LaTeX. This format is crucial for preserving the mathematical structure and ensuring accurate representation.
Beyond simply extracting the formulas, Claude can also generate metadata about them. This metadata might include information such as the formula’s type (e.g., equation, inequality), the variables involved, and any relevant context from the surrounding text. This metadata enriches the extracted information and makes it more easily searchable and understandable.
The Amazon Bedrock Converse API further enhances this process by enabling conversational interaction with Claude. Users can ask questions about the extracted formulas in natural language, and Claude will provide clear and concise explanations. For example, a user could ask, “What is the purpose of this formula?” or “Explain the meaning of each variable in this equation.” Claude’s ability to understand and respond to these types of queries makes it a powerful tool for researchers and engineers who need to quickly grasp the meaning and significance of complex formulas.
Interpreting Graphs and Generating Summaries
Another significant capability of multi-modal generative AI models is their ability to interpret graphs and generate corresponding summaries and metadata. The following illustrates how metadata for charts and graphs can be obtained through simple natural language interaction with the models.
Similar to formula extraction, the process of graph interpretation begins by providing Claude with an image of the graph. Claude’s vision capabilities allow it to analyze the graph’s structure, identify the axes, labels, and data points, and understand the overall trend or pattern being presented.
Based on this analysis, Claude can generate a summary of the graph’s key findings. This summary might describe the relationship between the variables, highlight any significant trends or outliers, and provide an overall interpretation of the data. The summary is presented in natural language, making it easy for users to understand the graph’s meaning without having to manually analyze the data themselves.
In addition to the summary, Claude can also generate metadata about the graph. This metadata might include information such as the graph’s type (e.g., line graph, bar chart, scatter plot), the units of measurement for each axis, and any relevant statistical measures (e.g., mean, standard deviation). This metadata further enhances the graph’s searchability and allows users to quickly find and understand relevant visualizations.
The ability to interact with Claude in natural language makes this process even more powerful. Users can ask specific questions about the graph, such as “What is the maximum value of Y in this graph?” or “What is the trend of the data over time?”. Claude’s ability to understand and respond to these queries makes it an invaluable tool for researchers and engineers who need to quickly extract insights from complex visualizations.
Generating Metadata for Enhanced Searchability
Leveraging natural language processing, metadata for the research paper can be generated to significantly improve its searchability. This metadata encompasses key aspects of the paper, making it easier to locate and retrieve relevant information.
The process of generating metadata for the entire research paper leverages Claude’s natural language processing (NLP) capabilities. By analyzing the text of the paper, Claude can identify key concepts, topics, and entities. This information is then used to generate metadata tags that accurately describe the paper’s content.
The metadata generated might include:
- Keywords: A list of keywords that represent the main topics discussed in the paper.
- Abstract Summary: A concise summary of the paper’s abstract, highlighting the key findings and conclusions.
- Author Information: Information about the authors, including their names and affiliations.

Data Chunking: The ingested data is divided into smaller chunks. This is done to improve the efficiency of the search process and to ensure that the knowledge base can handle large amounts of data.
Embedding Generation: Embeddings are generated for each chunk of data. Embeddings are numerical representations of the text that capture its semantic meaning. These embeddings are used to perform similarity searches, allowing the knowledge base to find the most relevant chunks of data in response to a user’s query.
Knowledge Base Indexing: The knowledge base is indexed, creating a data structure that allows for fast and efficient searching.
Knowledge Base Configuration: The knowledge base is configured, specifying parameters such as the embedding model to be used and the search algorithm to be employed.
Once the knowledge base is created, it can be used to answer questions about the processed documents. Users can ask questions in natural language, and the knowledge base will search for the most relevant chunks of data and provide a concise answer.
Querying the Knowledge Base for Targeted Information Retrieval
The knowledge base can be queried to retrieve specific information from the extracted formula and graph metadata within the sample documents. Upon receiving a query, the system retrieves relevant chunks of text from the data source. A response is then generated based on these retrieved chunks, ensuring that the answer is directly grounded in the source material. Importantly, the response also cites the relevant sources, providing transparency and traceability.
The query process involves several steps:
Query Understanding: The knowledge base first understands the user’s query, identifying the key concepts and entities being asked about.
Similarity Search: The knowledge base then performs a similarity search, using the embeddings generated during the knowledge base creation process. This search identifies the chunks of data that are most semantically similar to the user’s query.
Response Generation: Based on the retrieved chunks of data, the knowledge base generates a concise and informative response to the user’s query. This response is typically presented in natural language.
Source Citation: The response includes citations to the relevant sources from which the information was extracted. This provides transparency and allows users to verify the accuracy of the information.
The ability to query the knowledge base in natural language makes it a powerful tool for researchers and engineers. They can ask specific questions about the processed documents and receive accurate and informative answers, without having to manually search through the entire dataset.
