CLAIM is a contextual language model designed to accurately impute missing data in tables using contextual text generated by large language models. Unlike traditional methods such as mean, mode, or kNN, CLAIM leverages the semantic context of descriptions, notes, and other textual fields to fill in numerical or categorical values, improving data quality and the accuracy of downstream analysis and prediction tasks.

How CLAIM works: the system converts related columns and descriptions into enriched textual representations, queries a language model to generate imputations consistent with the context, and validates responses through integrity rules and domain statistics. This approach reduces imputation biases, preserves relationships between variables, and often improves performance in classification and regression models used in BI and machine learning.

Key benefits: higher data fidelity, less need for manual engineering, better performance in downstream models, and greater robustness against outliers. Comparative studies show that contextual methods like CLAIM outperform conventional techniques in prediction and classification tasks when textual information is associated with table rows.

Use cases: data cleaning for business intelligence tools and dashboards in Power BI, imputation in data pipelines for enterprise AI models, enrichment of customer records in CRM, and preparation of financial or medical data where contextual information is critical for automated decisions.

Integration with modern infrastructures: CLAIM can be deployed alongside cloud solutions such as AWS and Azure cloud services, integrating into ETL processes and advanced analytics environments. Its modular design facilitates orchestration with AI agents and enterprise artificial intelligence platforms to automate workflows.
