# METEOR
**Objective:**
METEOR was designed to address some shortcomings of BLEU, particularly for machine translation. It evaluates machine-generated text by considering synonyms, stemming, and word order, giving higher importance to meaning and linguistic structure. METEOR uses precision, recall, and an F1-score, with additional weighting based on semantic similarity and word alignment, making it more flexible for tasks that require nuanced linguistic evaluations. It is popular for translation evaluation but can be extended to other text generation tasks.
**Required Columns in Dataset:**
`LLM Summary`, `Reference Document (GT)`
**Interpretation:**
* **High METEOR**: Reflects good alignment, considering synonyms, stemming, and word order, meaning the generated output is both semantically and syntactically aligned with the reference.
* **Low METEOR**: Implies limited semantic matching, with possible differences in vocabulary, ordering, or inability to capture linguistic variations.
**Execution via UI:**
METEOR does not require an LLM for computation.
**Execution via SDK:**
```python
metrics=[
{"name": "METEOR", "column_name": "your-text", "schema_mapping": schema_mapping}
]
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.raga.ai/ragaai-catalyst/ragaai-metric-library/text-summarization/meteor.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
