Science of Science: An Integrated Pipeline for Tracing Conceptual Emergence and Evolution in Semantic Space

The project implements an integrated pipeline for science mapping that links: data collection (OpenAlex) → pre-processing → network & embedding representations → analysis → interactive dashboard.

What it does

• Collects and caches publication metadata from the OpenAlex API for a target concept (default: "Urban Digital Twin").
• Builds keyword co-occurrence networks (overall and per-year slices).
• Builds semantic similarity networks from Word2Vec embeddings trained on titles/abstracts/keywords.
• (Optional) Builds concept-method bipartite networks using an LLM-based keyword labelling step (served via Ollama).
• Provides an interactive Dash dashboard with network visualisations (dash-cytoscape) and time series (plotly).
