Overview

Alias performs a series of automated tests on each survey response to detect various types of low-quality and fraudulent content. These basic checks include:
  1. Gibberish
  2. Off-topic
  3. Low-effort
  4. GPT-generated Content

​
Gibberish

Alias identifies responses that lack coherent semantic content and flags them as Automated test: Gibberish. Example:
  • Question: “What is your favorite book and why?”
  • Response: “asdfghjkl”

​
Off-topic

Responses that are unrelated to the question asked are flagged as Automated test: Off-topic. Example:
  • Question: “How do you approach problem-solving?”
  • Response: “I love going to the beach on sunny days.”

​
Low-effort

Alias flags responses with minimal information or insufficient detail as Low-effort. Example:
  • Question: “Describe a challenging project you worked on.”
  • Response: “No.”

​
GPT-generated

Responses that appear to be generated by GPT or another large language model (LLM) are flagged as Automated test: GPT. Example:
  • Question: “What strategies do you use to manage stress?”
  • Response: “As a large language model, I do not experience stress.”

​
Interpreting Basic Check Results

When a response fails one or more basic checks, it is included in the checks object of the API response. For example: 
"checks": {
  "Q1": [
    "Automated test: Off-topic",
    "Low-effort"
  ]
}
This indicates that the response to question “Q1” was flagged as both off-topic and low-effort. Use the results of these basic checks to quickly identify and filter out low-quality responses before proceeding with more in-depth analysis.
