Logics-Parsing-Omni Technical Report
Omni Parsing framework standardizes multimodal data parsing via a unified taxonomy and progressive parsing paradigm.
Key Findings
Methodology
The Omni Parsing framework bridges perception and cognition through three hierarchical levels: Holistic Detection, Fine-grained Recognition, and Multi-level Interpreting. Holistic Detection provides spatiotemporal grounding, Fine-grained Recognition performs symbolization and attribute extraction, and Multi-level Interpreting constructs reasoning chains from local semantics to global logic.
Key Results
- On OmniParsingBench, the Logics-Parsing-Omni model shows consistent improvements across all modalities, demonstrating a strong balance between structural fidelity and semantic interpretation.
- The model significantly enhances entity-rich reasoning on knowledge-intensive image samples.
- In the video domain, annotations for fine-grained shot analysis and long educational content are optimized, ensuring accurate temporal localization and narrative understanding.
Significance
This study introduces the Omni Parsing framework, addressing challenges of fragmented task definitions and heterogeneity in unstructured data, providing a method to convert complex audio-visual signals into machine-readable structured knowledge, significantly enhancing model reliability.
Technical Contribution
Proposes a unified parsing framework integrating perception and cognition, providing strict alignment from low-level signals to high-level semantics, enabling evidence-based logical induction.
Novelty
This framework is the first to transform multimodal signals into locatable, enumerable, and traceable standardized knowledge, significantly differing from existing methods.
Limitations
- The model may encounter performance bottlenecks when handling extremely complex audio-visual signals, particularly in real-time applications.
- Parsing of unstructured data still requires optimization to improve efficiency.
Future Work
Future research directions include optimizing real-time parsing capabilities, expanding the framework to support more types of unstructured data, and validating its effectiveness in more practical applications.
AI Executive Summary
Multimodal parsing has long faced challenges of fragmented task definitions and heterogeneity in unstructured data. Existing methods often lack layout fidelity and fine-grained grounding when dealing with visually rich documents and long educational videos. To address this, the Omni Parsing framework is proposed, combining perception and cognition through a unified taxonomy and progressive parsing paradigm. This framework includes three levels: Holistic Detection, Fine-grained Recognition, and Multi-level Interpreting, ensuring strict alignment between high-level semantic descriptions and low-level facts.
Experimental results show that the Logics-Parsing-Omni model demonstrates consistent improvements across all modalities on OmniParsingBench, proving the synergy between fine-grained perception and high-level cognition. This framework not only enhances model reliability but also achieves logical induction through an evidence anchoring mechanism, transforming complex audio-visual signals into machine-readable structured knowledge.
However, the framework still faces limitations when handling extremely complex signals, especially in real-time applications. Future research directions include optimizing real-time parsing capabilities, expanding the framework to support more types of unstructured data, and validating its effectiveness in more practical applications.
Deep Analysis
Background
The field of multimodal parsing has seen significant advancements, particularly with the rise of large-scale language models. However, existing methods often lack layout fidelity and fine-grained grounding when dealing with visually rich documents and long educational videos, leading to the loss of critical information and making deep retrieval and automated document conversion challenging.
Core Problem
The core problem in multimodal parsing is integrating fine-grained content parsing with deep semantic understanding without losing semantic value. Existing methods struggle to achieve a unified representation when dealing with complex layouts and diverse non-text visual content.
Innovation
The Omni Parsing framework combines perception and cognition through a unified taxonomy and progressive parsing paradigm. It includes three levels: Holistic Detection, Fine-grained Recognition, and Multi-level Interpreting, ensuring strict alignment between high-level semantic descriptions and low-level facts.
Methodology
- �� Holistic Detection: Achieves precise spatiotemporal grounding of objects or events to establish a geometric baseline for perception.
- �� Fine-grained Recognition: Performs symbolization (e.g., OCR/ASR) and attribute extraction on localized objects to complete structured entity parsing.
- �� Multi-level Interpreting: Constructs a reasoning chain from local semantics to global logic.
Experiments
The experimental design includes evaluations on OmniParsingBench, covering document, image, and audio-video content. The model is trained using knowledge-intensive image samples and optimized video annotations to ensure a balance between structural fidelity and semantic interpretation.
Results
Results show that the Logics-Parsing-Omni model demonstrates consistent improvements across all modalities, particularly enhancing entity-rich reasoning on knowledge-intensive image samples.
Applications
The framework can be applied to downstream tasks such as Retrieval-Augmented Generation, Question Answering, and intelligent tutoring, especially in scenarios requiring fine-grained parsing and deep semantic understanding.
Limitations & Outlook
While the framework performs well in multimodal parsing, it may encounter performance bottlenecks when handling extremely complex audio-visual signals, particularly in real-time applications.
Plain Language Accessible to non-experts
Imagine you're in a library with various books, images, and videos. The Omni Parsing framework acts like a super librarian, not only helping you find the books you need but also summarizing each book's main content, detailing the images, and highlighting key scenes in videos. It organizes all this information into an easy-to-understand format, like translating all the books and videos into a language you can read.
ELI14 Explained like you're 14
Imagine you're playing a super complex game with many levels, each with different tasks and challenges. Omni Parsing is like a super helper that quickly finds key points in each level, tells you how to pass them, and even organizes a guide for you to excel in the game! Isn't that cool?

Abstract
Addressing the challenges of fragmented task definitions and the heterogeneity of unstructured data in multimodal parsing, this paper proposes the Omni Parsing framework. This framework establishes a Unified Taxonomy covering documents, images, and audio-visual streams, introducing a progressive parsing paradigm that bridges perception and cognition. Specifically, the framework integrates three hierarchical levels: 1) Holistic Detection, which achieves precise spatial-temporal grounding of objects or events to establish a geometric baseline for perception; 2) Fine-grained Recognition, which performs symbolization (e.g., OCR/ASR) and attribute extraction on localized objects to complete structured entity parsing; and 3) Multi-level Interpreting, which constructs a reasoning chain from local semantics to global logic. A pivotal advantage of this framework is its evidence anchoring mechanism, which enforces a strict alignment between high-level semantic descriptions and low-level facts. This enables ``evidence-based'' logical induction, transforming unstructured signals into standardized knowledge that is locatable, enumerable, and traceable. Building on this foundation, we constructed a standardized dataset and released the Logics-Parsing-Omni model, which successfully converts complex audio-visual signals into machine-readable structured knowledge. Experiments demonstrate that fine-grained perception and high-level cognition are synergistic, effectively enhancing model reliability. Furthermore, to quantitatively evaluate these capabilities, we introduce OmniParsingBench.
