Quantifying Interdisciplinarity in Scientific Articles Using Deep Learning Toward a TRIZ-Based Framework for Cross-Disciplinary Innovation
Our deep learning approach utilizes a Text Convolutional Neural Network (Text CNN) to semantically analyze scientific titles and abstracts, quantifying interdisciplinarity with an F1 score of 0.82. This model, trained on the Semantic Scholar Open Research Corpus (S2ORC), reveals that approximately 25% of scientific literature within specified disciplines is interdisciplinary. Integrated into a TRIZ-based framework, this method provides a scalable solution for systematic knowledge transfer and inventive problem solving, driving cross-disciplinary innovation.

The Challenge of Interdisciplinarity Quantification
Interdisciplinary research (IDR) is critical for solving complex global problems, yet its quantification remains a challenge due to conceptual ambiguities and inconsistent methodologies. Traditional methods like bibliometrics often miss the depth of integration within research content. Our approach addresses this by leveraging deep learning for semantic analysis.
This deep learning model provides a scalable and robust way to identify IDR, moving beyond metadata to analyze the actual scientific content. This capability is crucial for organizations looking to foster innovation, identify emerging fields, and make strategic decisions based on true cross-domain knowledge integration.
Deep Learning Methodology: Text CNN & S2ORC
Our method utilizes a Text Convolutional Neural Network (Text CNN) to analyze titles and abstracts from the Semantic Scholar Open Research Corpus (S2ORC), a dataset of over 100 million academic papers. Approximately one million papers were used for initial modeling, equally split between interdisciplinary and monodisciplinary examples, labeled based on metadata tags from Semantic Scholar's classification, which identifies papers tagged with more than one discipline as interdisciplinary.
Preprocessing Steps: Text data undergoes normalization (lowercase, punctuation removal), tokenization, lemmatization, stop word removal, and Byte Pair Encoding (BPE) for robust subword handling. The Text CNN architecture includes an embedding layer, convolutional layers with kernel sizes of 2 and 3 (to capture bi-grams and tri-grams), max-over-time pooling, fully connected layers with dropout, and a sigmoid activation for binary classification. Training involved the Adam optimizer with a learning rate of 0.001, binary cross-entropy loss, batch size 64, and early stopping based on validation loss.
Performance & Validation of the Text CNN Model
The Text CNN model demonstrated superior performance over baseline machine learning models, achieving an F1 score of 0.82 and a Matthews Correlation Coefficient (MCC) of 0.64. This indicates a strong balance between precision (0.80) and recall (0.83), effectively identifying interdisciplinary articles with a low rate of false positives.
Out of 26,999 holdout samples, the model correctly classified 21,908 papers. The precision-recall and ROC curves confirm the model's discriminative ability and balanced performance across various thresholds. Training and validation loss converged satisfactorily, suggesting good generalization without overfitting. The density plot of predicted probabilities further illustrates the model's confidence in its classifications.
Facilitating Innovation with TRIZ Framework
Our interdisciplinarity quantification method is designed to integrate into a TRIZ-based (Theory of Inventive Problem Solving) framework for systematic, cross-disciplinary innovation. By identifying scientific articles rich in cross-disciplinary content, the model acts as an initial filter, prioritizing literature for TRIZ analysis.
The TRIZ framework, which emphasizes systematic innovation and knowledge transfer across domains, can then be applied to these identified articles. This involves contradiction identification and the application of inventive principles to extract and adapt innovative solutions. For example, in advanced medical device development, the model can detect studies integrating biomedical engineering and materials science, allowing TRIZ principles to resolve contradictions like enhancing biocompatibility without compromising mechanical strength. This integration streamlines knowledge transfer and enhances systematic innovation, particularly focusing on Case C2 (solutions from another industry) as per the TRIZ-inspired Frames of Knowledge.
