• Title: Ensuring Responsible Sourcing of Large Language Model Training Data Through Knowledge Graph Comparison
• Authors: Devam Mondal, Carlo Lipizzi,
• Abstract summary: Recently, publishers, newspapers, and other creators of copyrighted corpora against large language model (LLM) developers have been accused of plagiarism. We propose a novel system, a variant of a plagiarism detection system, that assesses whether a knowledge source has been used in the training or fine-tuning of a large language model.

• Abstract: In light of recent plagiarism allegations Brough by publishers, newspapers, and other creators of copyrighted corpora against large language model (LLM) developers, we propose a novel system, a variant of a plagiarism detection system, that assesses whether a knowledge source has been used in the training or fine-tuning of a large language model. Unlike current methods, we utilize an approach that uses Resource Description Framework (RDF) triples to create knowledge graphs from both a source document and a LLM continuation of that document. These graphs are then analyzed with respect to content using cosine similarity and with respect to structure using a normalized version of graph edit distance that shows the degree of isomorphism. Unlike traditional systems that focus on content matching and keyword identification between a source and target corpus, our approach enables a broader evaluation of similarity and thus a more accurate comparison of the similarity between a source document and LLM continuation by focusing on relationships between ideas and their organization with regards to others. Additionally, our approach does not require access to LLM metrics like perplexity that may be unavailable in closed large language modeling "black-box" systems, as well as the training corpus. A prototype of our system will be found on a hyperlinked GitHub repository.

  We propose a simple yet effective method, Global-Local Semantic Consistent Learning (GLSCL) GLSCL capitalizes on latent shared semantics across modalities for text-video retrieval. Our method achieves comparable performance with SOTA as well as being nearly 220 times faster in terms of computational cost.

  Existing text scaling methods often require a large corpus, struggle with short texts, or require labeled data. We develop a text scaling method that leverages the pattern recognition capabilities of generative large language models. We demonstrate how combining substantive knowledge with LLMs can create state-of-the-art measures of abstract concepts.

  Autoregressive language models are emerging as the de-facto standard for generating answers. Previous work has explored ways to partition the search space into hierarchical structures. In this work we propose an alternative that doesn't force any structure in the search space: using all ngrams in a passage as its possible identifiers.

We use a consolidated, curated version of the crowdsourced assessments to train several machine learning models to scale up the analysis to the whole of Wikidata. The findings help us ascertain the quality of references in Wikidata, and identify common challenges in defining and capturing the quality of user-generated multilingual structured data on the web.
