📖 English–Khmer Dictionary Dataset
A comprehensive bilingual English–Khmer (ភាសាខ្មែរ) dictionary dataset in CSV format containing 170,000+ entries. Each entry includes the original English word, its Khmer translation, part of speech, full definitions in both languages, and example sentences — making it one of the richer English–Khmer lexical resources available for NLP and language learning.
Dataset Description
This dataset provides structured dictionary entries pairing English words with Khmer translations. With over 170,000 entries covering a wide range of vocabulary, it goes beyond simple word pairs by including part-of-speech tags, detailed definitions in both English and Khmer, and bilingual example sentences. It is well-suited for machine translation, language learning tools, and linguistic research on Khmer — a low-resource language spoken primarily in Cambodia.
Dataset Structure
The dataset is a single CSV file with the following columns:
| Column | Type | Description |
|---|---|---|
word |
string | The English headword |
word_km |
string | The Khmer translation of the headword (in Khmer script) |
pos |
string | Part of speech (e.g., noun, verb, prep., adj.) — may be empty |
definition_en |
string | Full definition in English |
definition_km |
string | Full definition in Khmer script |
example_en |
string | Example sentence in English (may be empty) |
example_km |
string | Example sentence in Khmer (may be empty) |
Note: Some entries have multiple rows for the same headword, each representing a different sense or meaning.
Sample Data
| word | word_km | pos | definition_en | definition_km |
|---|---|---|---|---|
| A | ក | An adjective, commonly called the indefinite article... | គុណនាម ដែលជាទូទៅគេហៅថា អត្ថបទមិនកំណត់... | |
| A | ក | prep. | In; on; at; by. | នៅក្នុង; នៅលើ; នៅ; ដោយ. |
| A | ក | Of. | នៃ។ |
Usage
from datasets import load_dataset
dataset = load_dataset("mrrtmob/english-khmer-dictionary")
print(dataset["train"][0])
Or load directly with pandas:
import pandas as pd
df = pd.read_csv("dictionary.csv")
# Look up a word
results = df[df["word"].str.lower() == "hello"]
print(results[["word", "word_km", "pos", "definition_en"]])
Languages
- Source language: English (
en) - Target language: Khmer (
km) — spoken by ~16 million people, primarily in Cambodia
Potential Use Cases
- Training or fine-tuning English↔Khmer machine translation models
- Building Khmer dictionary or language learning applications
- Part-of-speech tagging and annotation for Khmer NLP pipelines
- Augmenting low-resource Khmer NLP datasets
- Linguistic and lexicographic research on the Khmer language
Data Collection
The English headwords and definitions were sourced from OPTED (The Online Plain Text English Dictionary) v0.03, a public domain English dictionary maintained by the Australian National University (ANU) at https://www.mso.anu.edu.au/~ralph/OPTED/v003/. OPTED itself is based on Webster's Unabridged Dictionary (1913 edition), which is in the public domain.
The Khmer translations (word_km, definition_km, example_km) were generated using the Kiri translation model by Blizzer.tech, an AI-powered translation service specializing in Southeast Asian languages including Khmer.
⚠️ As the Khmer translations are machine-generated, some entries may contain translation errors or unnatural phrasing. Human review and correction is encouraged for production use.
