Question

Identify the organization that began donating daily crawl data to the Internet Archive starting in 1996. While their standard data flows are typically added to the Wayback Machine after an embargo period, locate the specific data collection donated by this organization covering the year 2008. What is the official name of this 2008 collection, and what is its current status regarding public accessibility?

Answer length: 100-200 words.

Depth checklist
  • Target Entity: Alexa Internet (or Alexa Crawls)
  • Logic Proof: Identified via the 1996 start date and daily donation relationship with the Internet Archive.
Width checklist
  • Official Collection Name: 'Alexa Web 2008'
  • Accessibility Status: Currently not publicly accessible
  • Standard Process Contrast: Mentions that standard data is added after an embargo (unlike the 2008 set)
Examiner rationale

The question utilizes Deep Reasoning by masking the subject 'Alexa Internet' behind its historical relationship with the Internet Archive (1996 start date). It then applies Wide Aggregation by requiring the agent to distinguish the specific 'Alexa Web 2008' collection from the general daily flows and retrieve its unique accessibility status (not public) as defined in the source text. Note: The source text provided was unrelated to the 'History of swimwear' domain label; the question adheres to the 'Absolute Grounding' rule by strictly utilizing the provided text about Web Archiving.

Judgment

Both agents correctly identify the organization (Alexa Internet) and the restricted status of the 2008 data. However, Agent B provides a significantly superior User Experience. 1. **Formatting**: Agent B uses bolding to highlight the specific answers (Collection Name, Status) and breaks the text into readable paragraphs. Agent A provides a single 'wall of text' paragraph. 2. **Nuance/Logic**: Agent B correctly distinguishes between the standard 6-month embargo for Wayback Machine integration and the permanent restriction on the bulk 'Alexa crawls 2008' collection. Agent A confusingly suggests the 2008 data is still 'pending' integration, which is logically unsound for data that is 16 years old. 3. **Citations**: Agent B provides fully formatted citations, whereas Agent A provides minimal details.

Alexa Internet, Inc. began supplying the Internet Archive with its daily web-crawl data in 1996. For the 2008 coverage, the donated dataset is catalogued at the Internet Archive as “Alexa Crawls 2008.” According to the collection page, the data are presently “Not publicly downloadable; access is restricted,” pending the normal post-embargo integration into the Wayback Machine.

Alexa Internet, a company later acquired by Amazon, began donating its daily web crawls to the Internet Archive in 1996 [1, 2]. These donations were instrumental in building the Wayback Machine. While standard data flows were incorporated into the public Wayback Machine after a typical six-month embargo, the Internet Archive also maintains distinct collections of this bulk data. The specific data collection containing the crawls donated by Alexa for the year 2008 is officially named **"Alexa crawls 2008"** [3]. This collection holds the raw crawl data from that year. However, its current status is not open to the public. The official collection page on the Internet Archive explicitly states, "**This collection is not available to the general public**." Access is restricted, typically requiring special application and approval for academic or research purposes [3]. ## References [1] Internet Archive. (2019, October 25). *A new life for Alexa.com*.
