This shared task aims to benchmark Grammatical Error Detection (GED) and Grammatical Error Correction (GEC) systems for Indian languages. This task focuses on sentence-level categorization, detecting and correcting grammatically wrong sentences.
The participants are expected to solve the following three subtasks.

---

Subtasks

• Subtask 1: Detection of Grammatically Incorrect Sentences
  Given a sentence in an Indian language, determine whether it is grammatically correct or incorrect. (Binary Classification)
• Subtask 2: Grammatical Error Detection (GED)
  If the sentence is incorrect, classify the type of grammatical error (Multi-class Classification with 5+1 categories). It will be a sequence tagging task, analogous to NER, where participants are expected to predict whether each word in a sentence is correct or not. They must tag the word to the correct error category if it is incorrect.
• Subtask 3: Grammatical Error Correction (GEC)
  Generate the grammatically correct version of the input sentence, preserving the original intent and structure as much as possible. (Sequence Generation)

Evaluation Metrics

• Subtask 1: Macro-F1
• Subtask 2: Macro-F1
• Subtask 3: GLEU Score

This shared task aims to introduce and regularize the concept of Word Grouping in Indian languages. Word grouping is a process wherein, given a plain text sentence in an Indian language, the task is to output a sequence of word groups, where each group represents a semantically cohesive unit.

Supervised Monolingual Word Group Identification

The participants are expected to build models for word group identification within a single Indian language, using fully supervised data. Training and development data will be provided in a specific language (e.g., Hindi). Participants must predict semantically cohesive word groups on a held-out test set in the same language. Use of any approach -- rule-based, statistical, or neural models -- is allowed. Evaluation will focus on boundary-level matching and group-level correctness. This task serves as the foundational task to establish baselines for word grouping quality.
