+## 🔍 Model Description
+
+**ChronoSense** is a comprehensive system designed for the automated processing of scientific documents (primarily PDFs). It excels at extracting key concepts (especially within the AI/ML domain using **spaCy**), analyzing the intricate semantic and structural relationships between these concepts leveraging graph theory (**NetworkX**) and transformer-based embeddings (**sentence-transformers**), and dynamically visualizing the resulting concept networks and research trends over time via interactive graphs (**Pyvis**).
+
+The core goal of ChronoSense is to empower researchers by providing tools to effectively navigate the dense landscape of scientific literature, uncover hidden connections between ideas, and gain insights into the evolution and dynamics of research fields. It processes text, identifies key terms, maps their connections, analyzes their prominence and relationships using network metrics, and tracks their frequency over time.
+
+### 🌟 Key Features
+
+- **📄 Automated PDF Processing**: Extracts text and attempts to identify metadata (like publication year) from scientific PDF documents.
+- **🧠 Concept Extraction (spaCy)**: Identifies domain-specific concepts and terms using NLP techniques (custom rules, potentially NER).
+- **🔗 Relationship Detection**: Discovers semantic (co-occurrence, embedding similarity) and structural (e.g., section co-location) relationships between concepts.
+- **🕸️ Network Analysis (NetworkX)**: Builds concept networks, calculates centrality metrics (degree, betweenness, etc.), and performs community detection to find clusters.
+- **↔️ Semantic Similarity (sentence-transformers)**: Measures conceptual similarity using pre-trained transformer embeddings.
+- **⏳ Temporal Analysis**: Tracks concept frequency over publication time and can calculate trend indicators like concept half-life.
+- **📊 Interactive Visualization (Pyvis)**: Creates interactive HTML graphs where nodes (concepts) and edges (relationships) are styled based on calculated metrics (centrality, frequency, etc.).
+
+## 🚀 Why ChronoSense is Useful
+
+ChronoSense tackles several critical challenges faced by researchers today:
+
+1.  **Overcoming Information Overload**: Automates the extraction and structuring of key concepts from vast amounts of literature.
+2.  **Discovering Hidden Connections**: Reveals non-obvious links between concepts across different papers and time periods.
+3.  **Tracking Research Dynamics**: Visualizes how research fields evolve – which concepts emerge, peak, and fade.
+4.  **Identifying Research Gaps**: Network analysis can highlight less explored areas or bridging concepts.
+5.  **Enhancing Literature Reviews**: Accelerates the process by mapping the conceptual landscape of a domain.
+6.  **Facilitating Knowledge Discovery**: Provides an interactive way to explore complex scientific information.
+
+## 💡 Intended Uses
