Mapping Literature Landscapes with Data-Driven Discovery: A Case Study on MOEA/D

2024-04-22

AI Summary

Faced with the challenge of analyzing evolving research landscapes amid exponential growth in scientific literature, this paper proposes LitLA—a novel end-to-end literature analysis workflow. LitLA pioneers a full-lifecycle knowledge graph construction paradigm tailored to the scholarly ecosystem. It integrates publication metadata with advanced techniques including knowledge graph construction, temporal graph embedding, dynamic network analysis, and interpretable topic modeling to enable multidimensional modeling and evolutionary inference of the MOEA/D research domain. The resulting knowledge graph encompasses over 5,400 papers, 10,000 authors, 1,600 institutions, and 78,000 keywords. It supports fine-grained tracking of thematic evolution, visualization of academic community dynamics, and interpretable forecasting of future research trends. By unifying heterogeneous scholarly signals within a scalable, graph-based framework, LitLA significantly enhances the systematicity and scalability of large-scale intelligent literature analysis.

Abstract

We are living in an era of"big literature", where scientific literature is expanding exponentially. While this growth presents new opportunities, it complicates mapping global scientific research landscapes, as manual review methods become infeasible. Recent advancements in machine learning, complex networks, and natural language processing have enabled numerous data-driven discovery methods. Building upon these tools, we introduce an end-to-end workflow for analyzing large-scale literature landscapes, LitLA. This workflow first integrates diverse publication metadata into a bibliographic knowledge graph (KG) representing the research landscape. It then offers tools for exploratory analysis of various landscape aspects. We demonstrate the effectiveness of LitLA via a case study on follow-up works of multi-objective evolutionary algorithm based on decomposition (MOEA/D). In doing so, we constructed the MOEA/D research landscape as a KG comprising over 5,400 papers, 10,000 authors, 1,600 institutions, and 78,000 keywords. With this landscape, we start with descriptive statistics and investigate prominent topics pertaining to MOEA/D and interrogate their spatial-temporal and bilateral relationships. We then map the collaboration and citation networks to reveal the community's growth over time. We further experiment whether learning on latent patterns of this landscape can hint on future research directions.
