Dataset Description

Dataset Summary

ConceptNet is a multilingual knowledge base, representing words and phrases that people use and the common-sense relationships between them. The knowledge in ConceptNet is collected from a variety of resources, including crowd-sourced resources (such as Wiktionary and Open Mind Common Sense), games with a purpose (such as Verbosity and, and expert-created resources (such as WordNet and JMDict).

This dataset is designed to provide training data for common sense relationships pulls together from various sources.

The dataset is multi-lingual. See langauge codes and language info here:

This dataset provides an interface for the conceptnet5 csv file, and some (but not all) of the raw text data used to build conceptnet5: omcsnet_sentences_free.txt, and omcsnet_sentences_more.txt.

One use of this dataset would be to learn to extract the conceptnet relationship from the omcsnet sentences.

Conceptnet5 has 34,074,917 relationships. Of those relationships, there are 2,176,099 surface text sentences related to those 2M entries.

omcsnet_sentences_free has 898,161 lines. omcsnet_sentences_more has 2,001,736 lines.

The omcsnet data comes with the following warning from the authors of the above site:

Dataset Structure

Data Instances

There are three configurations for the dataset: conceptnet5, omcs_sentences_free, omcs_sentences_more.

Conceptnet5 defines:

{ 'sentence': ..., 'full_rel': ..., 'rel': ..., 'arg1': ..., 'arg2': ..., 'lang': ..., 'extra_info': ... 'weight': ... }

The omcs text defines: { 'sentence': ..., 'raw_data': ... 'weight': ... }

Data Fields

For conceptnet5 configurations:

  • full_rel: the full relationship. e.g., /a/[/r/Antonym/,/c/en/able/,/c/en/cane/]
  • rel: the binary relationship. e.g., /r/Antonym
  • arg1: the first argument to the binary relationship. e.g., /c/en/able
  • arg2: the second argument to the binary relationship. e.g., /c/en/cane
  • lang: the language code. e.g., en, fr, etc. If the arg1 and arg2 are two different languages, then the form os lang1/lang2.
  • extra_info: a string that includes json data that has the dataset name, license type (mostly cc-4.0), contributor, etc. e.g., : {"dataset": "/d/verbosity", "license": "cc:by/4.0", "sources": [{"contributor": "/s/resource/verbosity"}], "surfaceEnd": "cane", "surfaceStart": "able", "surfaceText": "[[able]] is the opposite of [[cane]]", "weight": 0.299}
  • sentence: the sentence from which the relationship was extracted, if one exists, with brackets around the arg1 and arg2. e.g., [[able]] is the opposite of [[cane]]
  • weight: the weight assigned by the curators or automatically to the relationship, between 1.0-0.0, higher being more certain.

For the omcs text configurations:

  • sentence: the raw sentence
  • raw_data: the raw tab seperated data of the form, id, text, curator_id, created_on, lanugage_id, activity_id, and score. Most of this information was tied to older systems for entering the data os was not partsed into fields for the dataset. e.g., 1237278 someone can be at catch 10805 2006-11-14 17:56:49.70872-05 en 27 1
  • lang: the language code

Dataset Creation

Curation Rationale

This dataset was gathered and created over many years for research in common sense reasoning.

Source Data

Initial Data Collection and Normalization

Started as the Open Mind Common Sense project at MIT Media Lab in 1999. See

Who are the source language producers?

Crowd Sourced


Annotation process

Crowd Source template text, games, etc.

Who are the annotators?

Crowd sourced.

Personal and Sensitive Information

Unkown, but likely there are names of famous individuals.

Considerations for Using the Data

Social Impact of Dataset

The goal for the work is to help machines understand common sense.

Discussion of Biases

See the website and paper for efforts to minimize data bias, but please note that omcs_sentences_free, omcs_sentences_more are raw data entered by users and may very well have biased data.

Other Known Limitations

While the relationship dataset is large, the amount of actual sentences is limited.
