Unveiling Novelty Evolution in the field of Library and Information Science in China
This study analyzes the novelty evolution of Chinese Library and Information Science research from 2000 to 2022 using BERTopic and combinatorial innovation theory, revealing that novelty has generally increased over time, varies significantly across topics (with archival research showing lower novelty and patent technology showing higher), and is positively associated with inter-institutional collaboration.

Imagine the field of Library and Information Science (LIS) in China as a massive, bustling kitchen where thousands of chefs (researchers) are cooking up new recipes (scholarly papers) every year. This study is like a food critic who has spent 22 years (from 2000 to 2022) tasting every dish, sorting them by flavor profile, and trying to figure out which recipes are truly "new and exciting" versus which ones are just reheating leftovers.
Here is the breakdown of what the researchers found, using simple analogies:
1. The Big Picture: Sorting the Menu
First, the researchers used a smart computer program (called BERTopic) to read the abstracts of nearly 45,000 papers. Think of this like a robot chef who reads the ingredients list of every dish and groups them into 15 distinct "flavor categories."
Some of these categories included:
- The "Library Service" Pot: Focused on helping people read and find books.
- The "Archive" Pot: Focused on old documents, handwriting, and preserving history.
- The "Patent & Tech" Pot: Focused on new inventions, technology, and methods.
- The "Journal Rating" Pot: Focused on how to judge the quality of other academic magazines.
2. What Makes a Dish "Novel"? (The Innovation Score)
The researchers wanted to know: Which papers are actually doing something new?
To measure this, they didn't just ask the authors, "Is this new?" Instead, they looked at the ingredients (the references) the authors used.
- The Analogy: Imagine a chef who only uses salt and pepper. That's not very novel. But imagine a chef who suddenly decides to mix sushi with pizza. That's a weird, rare combination.
- The Method: The study looked at the "journal pairs" cited in each paper. If a paper cites two journals that rarely ever appear together in the same bibliography, that paper gets a high "Novelty Score." It's a "rare combination." If a paper cites the same three journals everyone else cites, it gets a low score.
3. The Findings: Who is Cooking the "New" Stuff?
A. The "Old School" vs. The "Cutting Edge"
- Low Novelty (The Comfort Food): Papers about archives, handwriting, and old documents tended to have the lowest novelty scores. The researchers suggest this is like cooking a traditional family recipe that hasn't changed in 100 years. The methods are stable, the ingredients are known, and there's less room for wild experimentation.
- High Novelty (The Fusion Cuisine): Papers about patents, technology, journal evaluations, and virtual communities had the highest novelty scores. These are like fusion dishes. They mix different fields (like law, tech, and culture), requiring chefs to try strange new ingredient combinations.
B. The Trend Over Time
- Overall, the "novelty" of the field has been slowly creeping up, like a pot of water slowly heating up.
- Interestingly, the topic of "Open Access" (free online journals) was very "novel" around the year 2000 (because it was a brand new idea). But as everyone started doing it, the novelty score dropped because it became the "standard" way of cooking. Recently, it's starting to pick up steam again as new twists are added.
4. The Secret Ingredient: Teamwork
The most interesting finding was about who is cooking the dishes.
- Solo Chefs (One Author): Papers written by a single person were much more common in the "Low Novelty" categories (like archives). The researchers suggest that when you are working on very specific, traditional topics, you might not need a team. You can do it alone in your kitchen.
- The Super-Team (Multiple Authors): Papers with the highest novelty scores were almost always cooked by teams, especially teams where the chefs came from different universities (Inter-institutional collaboration).
- The Analogy: If you want to invent a flying car, you probably need a mechanic, an aerodynamicist, and a software engineer working together. If they all work in the same garage (same university), they might think alike. But if they come from different garages, they bring different tools and ideas, leading to a more "novel" invention.
Summary
The study concludes that in the world of Chinese Library Science:
- Traditional topics (like preserving old papers) are stable but less "new."
- Tech and interdisciplinary topics (like patents and data) are the hotbeds of new ideas.
- Teamwork is key: If you want to create something truly novel, you need a team of chefs from different kitchens bringing their unique ingredients to the table. Solo chefs tend to stick to the classics.
The researchers admit their "taste test" has limits (they couldn't taste the actual food, only read the ingredient lists), but it gives a clear map of where the field is heading and how collaboration fuels innovation.
