figuresuch

figuresuch is a term used in information retrieval and digital libraries to denote the practice and technology of searching for figures embedded in digital documents, especially scholarly papers. The word combines figure and search to emphasize locating visual content and retrieving its associated data. In practice, figuresuch encompasses content-based image retrieval techniques, caption and metadata analysis, and cross-document linking to datasets or source code.

Origins and scope: The concept emerged in academic discussions during the 2010s as researchers sought ways to navigate the growth of figures in journals, theses, and reports. Figuresuch aims to support queries such as finding graphs that illustrate a particular trend or retrieving diagrams of a specified model, enabling more precise access to visual information beyond text alone.

Methods and data model: Implementations typically combine visual feature extraction from figures (such as color distributions, shapes, or deep-learning embeddings) with textual analysis of captions, figure legends, in-text references, and surrounding discourse. A common workflow includes extracting figures from documents, generating feature vectors, indexing metadata, and supporting multimodal queries that blend image similarity with caption or keyword search. Some proposals include lightweight metadata schemas and identifiers to improve provenance, licensing, and reusability of figures.

Applications and challenges: Figuresuch is used by researchers to locate relevant visuals, by publishers to enhance search interfaces, and by educators to assemble teaching materials. Key challenges include accurate extraction of figures from complex layouts, correct classification of figure types, disambiguating captions, navigating copyright restrictions, and maintaining up-to-date indexes as new publications appear.
