This dataset is a collection of tweets related to nuclear energy along with the crowd’s evaluation of the tweet’s sentiment. The possible sentiment categories are: “Positive,” “Negative,” “Neutral/author is just sharing information,” “Tweet NOT related to nuclear energy,” and “I can’t tell.” We also provide an estimation of the crowds’ confidence that each category is correct which can be used to identify tweets whose sentiment may be unclear.

Decide whether two English sentences are related

This dataset is a collection of English sentence pairs. The crowd was asked about the truth value of the second sentence if the first sentence were true and to what extent the sentences are related on a scale of 1 to 5. The variance of this score over the crowd’s judgments is included as well.

Weather sentiment

This job is best when viewed with the following job, “Weather sentiment evaluated.”

Here, contributors were asked to grade the sentiment of a particular tweet relating to the weather. The catch is that 20 contributors graded each tweet. We then ran an additional job (the one below) where we asked 10 contributors to grade the original sentiment evaluation.

Weather sentiment evaluated

Here, contributors were asked if the crowd graded the sentiment of a particular tweet relating to the weather correctly. The original job (above this one, called simply “Weather sentiment”) involved 20 contributors noting the sentiment of weather-related tweets. In this job, we asked 10 contributors to check that original sentiment evaluation for accuracy.

Data set contains URL of images, sentiment scores of highly positive, positive, neutral, negative, and highly negative, and contributor agreement.

Smart phone & tablet names database

Contributors viewed a particular model code (like C6730 or LGMS323), then searched for the name of the device itself (Kyocera C6730 Hydro or LG Optimus L70), then noted whether the device was a phone or tablet.

Free text object descriptions

Contributors viewed a pair of items and were asked to write sentences that described and differentiated the two objects. In other words, if viewing an apple and a orange, they could not write, “this is a piece of fruit,” twice, but needed to note how they were different. Image pairings varied so that the same image would appear in different couples and the second image was always smaller. Data set contains URLs of images and three sentences written per item, per image.

News article / Wikipedia page pairings

Contributors read a short article and were asked which of two Wikipedia articles it matched most closely. For example, a brief biography of Mel Gibson could be paired with Gibson’s general Wikipedia page or Lethal Weapon; likewise, Iran election results could be paired with a Wikipedia page on Iran in general or the 2009 protests. Data set contains URLs for both Wiki pages, the full text contributors read, and their judgments on each row.

Is-A linguistic relationships

Contributors were provided a pair of concepts in a constant sentence structure. Namely: [Noun 1] is a [noun 2]. They were then asked to simply note if this sentence was then true or false. Data set contains all nouns and aggregated T/F judgments.

Objective truths of sentences/concept pairs

Contributors read a sentence with two concepts. For example “a dog is a kind of animal” or “captain can have the same meaning as master.” They were then asked if the sentence could be true and ranked it on a 1-5 scale. On the low end was “strongly disagree” and on the upper, “strongly agree.” Data set includes over 8,000 concept pairings, averaged agreement scores, and associated variances.

Blurry image comparison

Contributors viewed a pair of purposely blurry or saturated images. They were then asked which image more closely matched a particular word. Data set contains URLs for all images and image pairs, aggregated agreement scores, and variance amounts. Notably, a high number of contributors were polled for each image pairing (20 in total for each, giving this data set upwards of 10,000 judgments).

Indian terrorism deaths database

Contributors counted the deaths mentioned in a sentence and whether they were terrorists, civilians, or security forces. Database contains original sentences, state and district in which the deaths occurred, dates of the deaths, and more. (Test questions have been removed from the database for ease of visualization.)

Drug relation database

Contributors read color-coded sentences and determined what the relationship of a drug was to certain symptoms or diseases. There are two types of relationships. A drug either:

  • Caused side effects – [Drug] gave me [symptom]
  • Was effective against a condition – [Drug] helped my [disease]
  • Is prescribed for a certain disease – [Drug] was given to help my [disease]
  • Is contraindicated in – [Drug] should not be taken if you have [disease or symptom]

The second similarity was more about the statement itself. Those broke down into:

  • Personal experiences – I started [drug] for [disease]
  • Personal experiences negated – [Drug] did not cause [symptom]
  • Impersonal experiences – I’ve heard [drug] causes [symptom]
  • Impersonal experiences negated – I’ve read [drug] doesn’t cause [symptom]
  • Question – Have you tried [drug]?

Image attribute tagging

Contributors viewed thousands of images and categorized each based on a given list of attributes. These attributes ranged from objective and specific (like “child” or “motorbike”) to more subjective ones (like “afraid” or “beautiful”). Data set includes URLs for all images, multiple tags for each, and contributor agreement scores.

Mobile search relevance

Contributors viewed a variety of searches for mobile apps and determined if the intent of those searches was matched. One was a short query like “music player”; the other, a much longer one like “I would like to download an app that plays the music on the phone from multiple sources like Spotify and Pandora and my library.”

Progressive issues sentiment analysis

Contributors viewed tweets regarding a variety of left-leaning issues like legalization of abortion, feminism, Hillary Clinton, etc. They then classified if the tweets in question were for, against, or neutral on the issue (with an option for none of the above). After this, they further classified each statement as to whether they expressed a subjective opinion or gave facts.

Blockbuster database

A data categorization job where we asked the crowd to find out information about the ten most popular movies, each year, for the past 40 years (1975-2015). Dataset includes:

Messages were broken down into audience (national or the tweeter’s constituency), bias (neutral/bipartisan, or biased/partisan), and finally tagged as the actual substance of the message itself (options ranged from informational, announcement of a media appearance, an attack on another candidate, etc.)

First GOP debate sentiment analysis

We looked through tens of thousands of tweets about the early August GOP debate in Ohio and asked contributors to do both sentiment analysis and data categorization. Contributors were asked if the tweet was relevant, which candidate was mentioned, what subject was mentioned, and then what the sentiment was for a given tweet. We’ve removed the non-relevant messages from the uploaded dataset.

Do these chemicals contribute to a disease?

Contributors read sentences in which both a chemical (like Aspirin) and a disease (or side-effect) were present. They then determined if the chemical directly contributed to the disease or caused it. Dataset includes chemical names, disease name, and aggregated judgments of five (as opposed to the usual three) contributors.

Disasters on social media

Contributors looked at over 10,000 tweets culled with a variety of searches like “ablaze”, “quarantine”, and “pandemonium”, then noted whether the tweet referred to a disaster event (as opposed to a joke with the word or a movie review or something non-disastrous).

Sentiment analyses of single words or short phrases

Contributors looked at four words or bigrams (bigrams are just word pairs) and ranked the most positive and most negative ones in each set. For example, they saw quartets like “nasty, failure, honored, females” and chose which word was the most positive and most negative. Interestingly, each set was graded by eight contributors instead of the usual three. Dataset contains all 3,523 rows, but has 28K judgments.

Gender classifier data

This data set was used to train a CrowdFlower AI gender predictor. You can read all about the project here. Contributors were asked to simply view a Twitter profile and judge whether the user was a male, a female, or a brand (non-individual). The dataset contains 20,000 rows, each with a user name, a random tweet, account profile and image, location, and even link and sidebar color.

Identifying key phrases in text

Contributors looked at question/answer pairs like, “When did Bob Marley die? 1981,” and a series of sentences surrounding that event such as phrases from a Bob Marley obituary. They marked which of those sentences spoke directly to the question such as, “Robert Nesta ‘Bob’ Marley, OM (6 February 1945 – 11 May 1981) was a Jamaican reggae singer, song writer, musician,” for a wide variety of topics.

Economic News Article Tone and Relevance

Contributors read snippets of news articles. They then noted if the article was relevant to the US economy and, if so, what the tone of the article was. Tone was judged on a 9 point scale (from 1 to 9, with 1 representing the most negativity). Dataset contains these judgments as well as the dates, source titles, and text. Dates range from 1951 to 2014.

Football Strategy

Contributors were presented a football scenario and asked to note what the best coaching decision would be. A scenario: “It is third down and 3. The ball is on your opponent’s 20-yard line. There are five seconds left. You are down by 4.” The decisions presented were punt, pass, run, kick a field goal, kneel down, or don’t know. There are thousands of such scenarios in this job.
