SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve? Identifying emerging research fronts and hot topics from large bibliographic datasets is time-consuming when done manually. This Skill automates keyword burst detection on cleaned Web of Science (WoS) plain text files, revealing which terms surged in specific time periods and how research trends evolved. ## Core Features & Use Cases - Burst Detection: Applies a simplified Kleinberg two-state automaton algorithm to find keywords with significant frequency surges, reporting burst strength, start/end years, and duration. - Trend & Phase Analysis: Groups burst keywords into research phases (early exploration, growth, frontier) and highlights emerging keywords from recent years. - Network Pruning Reference: Integrates CiteSpace pruning methods (Pathfinder, MST, Pruning Sliced Networks) and network metrics such as degree, betweenness, and closeness centrality. - Use Case: After cleaning a WoS dataset of 3,000+ papers, run this Skill to produce a ranked CSV of burst keywords, an ASCII timeline visualization, and a Top 50 high-frequency keyword list for a literature review. ## Quick Start Run keyword burst detection on my cleaned WoS plain text file and export the burst keyword results with strength scores and time ranges to a CSV file.

FAQPage Schema
How do I detect keyword bursts in Web of Science data?▼

Extract the PY, DE, and ID fields from the WoS plain text file, build a keyword-year frequency matrix, then apply Kleinberg burst detection to find terms whose frequency significantly exceeds the baseline. Results include burst strength, start year, and end year.

What is the Kleinberg burst detection algorithm?▼

Kleinberg's algorithm models each keyword as a two-state automaton (normal vs. burst) and finds the optimal state sequence minimizing cost. This Skill uses a simplified sliding-window version where burst strength equals window relative frequency divided by global relative frequency.

What input format does keyword burst analysis require?▼

The script expects a cleaned Web of Science plain text export file containing PY (year), DE (author keywords), and ID (Keywords Plus) fields, with records terminated by ER markers. Data should be deduplicated and cleaned beforehand.

What are the limitations of the simplified burst detection?▼

The simplified version skips Viterbi state optimization, cannot distinguish true bursts from long-term upward trends, and requires bursts to last at least two years. For publication-grade results, cross-validate with CiteSpace or a full Kleinberg implementation.

Why are no bursts detected for some keywords?▼

Keywords need a total frequency of at least 5, a burst window frequency of at least 3, and a strength above 2.0 to qualify. Low-frequency terms or evenly distributed terms across years will not produce burst intervals.
