# Cross-lingual plagiarism detection: Two are better than one
The widespread availability of scientific documents in multiple languages, coupled with the development of automatic translation and editing tools, has created a demand for efficient methods that can detect plagiarism across different languages.
A dataset for cross-lingual plagiarism evaluation. Collection consists of a subset of Wikipedia articles on 4 languages (ru, hy, es, en). Quary consists of wikipedia documents in each of the four languages with translated sentences with Google Translate API from collection, and also XML-markup for them.
# Usage of Dataset
## Load Data
```python
from datasets import load_dataset
ds = load_dataset("AntiplagiatCompany/CL4Lang")
```
## Create Index of collection
```python
# The list consists of dictionaries with document id, text of the document and text language information (also present xml data, but it used only for querys, not for indexing)
collection = ds['collection'].to_list()
# The list of object can be indexing by using different methods (vector search methods or classical BM25 indexing methods)
index = make_index(collection)
```
## Evaluate The Query Result
```python
# The list consists of dictionaries with document id, text of the document, text language information, and XML information about text reuses in query from collection.
queries = ds['query'].to_list()
real, predict = [], []
for query in queries:
real.append(query['xml'])
predict.append(
convert_answer_to_xml(
index.search(text=query['text'], lang=query['lang'])
)
)
# More information about the XML markup description and evaluation see http://pan.webis.de/clef13/pan13-web/plagiarism-detection.html
evaluate_system(real, predict)
```
