+# DepNeCTI-LSTM: Dependency-based Nested Compound Type Identification for Sanskrit
+
+This repository contains the datasets proposed in the paper [Sandhan et al., 2023](https://arxiv.org/abs/2310.09501)
+
+---
+# Summary
+
+The **NeCTIS** dataset is created for **nested compound type identification in Sanskrit**, focusing on multi-component compounds (especially with more than 2 components). It includes **coarse** and **fine-grained** semantic type annotations.
+
+### Key Features
+
+- **Two datasets**:
+  - **NeCTIS**: In-domain (Prose)
+  - **NeCTIS-OOD**: Out-of-domain (Poetry)
+
+- **Annotations**:
+  - **Coarse-level**: 4 broad compound types:
+    - **Avyayībhava** (Indeclinable)
+    - **Bahuvrīhi** (Exocentric)
+    - **Tatpurusha** (Endocentric)
+    - **Dvandva** (Copulative)
+  - **Fine-grained**: 86 detailed sub-types
+
+### Dataset Statistics
+
+| Dataset        | #Nested Compounds | Train  | Test  | Dev   | Compound Types |
+|----------------|-------------------|--------|-------|-------|----------------|
+| **NeCTIS**     | 17,656            | 12,431 | 3,493 | 2,405 | 4 (86)         |
+| **NeCTIS-OOD** | 1,189             | —      | 1,189 | —     | 4 (86)         |
+
+
+### Domain & Genre
+
+- **NeCTIS**: Philosophical, Literary, and Ayurvedic domains → *Prose*
+- **NeCTIS-OOD**: Paurāṇic (epic literature) domain → *Poetry*
+
+  - Poetry tends to include more novel, complex, and metrical compounds.
+
+### Annotation Process
+
+- Funded by **DeitY (2009–2012)** as part of the **Sanskrit-Hindi Machine Translation project**
+- Annotation done by **6 institutes**, each with ~10 members across 3 expertise levels:
+  - **Junior Linguist** (Master’s in Sanskrit)
+  - **Senior Linguist** (Ph.D. in Sanskrit)
+  - **Professional Linguist** (Professors)
+- Multi-level quality checks and **cross-institute validation**
+- Annotation guidelines based on **Pāṇinian grammar** and traditional commentaries.
+
+**For Detailed information refer to the original paper.**

+# Dive in the Dataset
+
+## With Context 
+- Total rows: **15,940 rows**.
+- Split: Train (69%), Test (18%), Dev (13%).
+- **train CSV**: **11,000 rows**.
+- **test CSV**: **2,940 rows**.
+- **dev CSV**: **2,000 rows**.
+- The **combined CSV**: all above files merged, 15,940 rows total.
+- These four CSV files include the following columns:  
+  `Unnamed: 0`, `Raw_Tagged`, `Clean`, `Bio_tagged`, `Span_Tagged`, `Coarse_tag`, `Compound_lengths`, `Coarse_Span_Tagged`.
+- The **out of Domain** contains **1139 rows**
+- The **out-of-domain** dataset has an additional column, `Book`, and lacks the `Compound_lengths` column.
+
+
+| Column Name        | Description                                                                                               |
+|--------------------|-----------------------------------------------------------------------------------------------------------|
+| **Unnamed: 0.1**   | Auto-generated row index by pandas when reading CSV, used as a unique identifier for each row.            |
+| **Unnamed: 0**     | Another index column created during CSV operations, often redundant with `Unnamed: 0.1`.                   |
+| **Raw_Tagged**     | Original input text with embedded annotation tags marking nested compound components and their types. Tags use angled brackets `< >` and suffix codes to show component boundaries and types. |
+| **Clean**          | Cleaned, tokenized version of the text without any annotation tags or special characters, for plain reading. |
+| **Bio_tagged**     | BIO tagging scheme at the token level indicating compound boundaries:   `B-C` = Beginning of a compound segment, `I-C` = Inside a compound segment, `O` = Outside any compound (non-compound token)                                                         |
+| **Span_Tagged**    | Token spans marking compound segments along with their labels. Format: `start,end Label`. Multiple spans are separated by `\|`. For example, `0,2 BvS\|2,5 Ds` means tokens from index 0 to 2 form a `BvS` compound, tokens 2 to 5 form a `Ds` compound. |
+| **Coarse_tag**     | Coarse-grained compound type annotations embedded with original tagged segments, indicating linguistic compound types such as `Bahuvrihi`, `Tatpurusha`, or `Dvandva`.  |
+| **Compound_lengths** | List indicating the length (number of tokens) of each compound segment in the text. For example, `[1, 1]` means there are two compounds each one token long.   |
+| **Coarse_Span_Tagged** | Combines span indices with coarse compound type labels to specify the token ranges and their compound categories. For example: `0,2 Bahuvrihi|2,5 Dvandva`. |
+|**Book**| Present in ood dataset. Informs about the book from which the sentence is taken.|

+| **Coarse_Span_Tagged** | Combines token span indices with coarse compound type labels, e.g., `0,2 Bahuvrihi\|2,5 Dvandva` specifies token ranges and their corresponding compound categories.    |
