+# IndicBERT_WOR: IndicBERT Telugu Sentiment Classification Model (Without Rationale)
+
+## Model Overview
+
+**IndicBERT_WOR** is a Telugu sentiment classification model based on **IndicBERT (ai4bharat/indicBERTv2-MLM-only)**, a multilingual BERT-like transformer developed by AI4Bharat.  
+The "WOR" in the model name stands for "**Without Rationale**", meaning this model is trained only with sentiment labels from the TeSent_Benchmark-Dataset and **does not use human-annotated rationales**.
+
+---
+
+## Model Details
+
+- **Architecture:** IndicBERT (BERT-like, multilingual for Indian languages)
+- **Pretraining Data:** OSCAR and AI4Bharat curated corpora for 12 Indian languages (including Telugu and English)
+- **Pretraining Objective:** Masked Language Modeling (MLM)
+- **Fine-tuning Data:** [TeSent_Benchmark-Dataset](https://huggingface.co/datasets/dsl-13-srmap/tesent_benchmark-dataset), using only sentence-level sentiment labels (positive, negative, neutral); rationale annotations are disregarded
+- **Task:** Sentence-level sentiment classification (3-way)
+- **Rationale Usage:** **Not used** during training or inference ("WOR" = Without Rationale)
+
+---
+
+## Intended Use
+
+- **Primary Use:** Benchmarking Telugu sentiment classification on the TeSent_Benchmark-Dataset as a **baseline** for models trained without rationales
+- **Research Setting:** Well suited for monolingual Telugu NLP tasks, especially in low-resource and explainable AI research
+
+---
+
+## Why IndicBERT?
+
+IndicBERT provides language-aware tokenization, clean embeddings, and faster training for Indian languages.  
+It is well suited for monolingual Telugu tasks, but does not support code-mixed data or cross-lingual transfer. For Telugu sentiment classification, IndicBERT delivers efficient and accurate results due to its tailored pretraining.
+
+---
+
+## Performance and Limitations
+
+**Strengths:**  
+- Language-aware tokenization and embeddings for Telugu
+- Faster training and inference compared to larger multilingual models
+- Robust baseline for monolingual Telugu sentiment classification
+
+**Limitations:**  
+- Not suitable for code-mixed or cross-lingual tasks
+- Telugu-specific models may outperform on highly nuanced or domain-specific data
+- Since rationales are not used, the model cannot provide explicit explanations for its predictions
+
+---
+
+## Training Data
+
+- **Dataset:** [TeSent_Benchmark-Dataset](https://huggingface.co/datasets/dsl-13-srmap/tesent_benchmark-dataset)
+- **Data Used:** Only the **Content** (Telugu sentence) and **Label** (sentiment label) columns; **rationale** annotations are ignored for IndicBERT_WOR training
+
+---
+
+## Language Coverage
+
+- **Language:** Telugu (`te`)
+- **Model Scope:** Strictly monolingual Telugu sentiment classification
