Question

When researching the early web presence and marketing of 1990s racing games through large-scale web archives, historians often rely on crawl data that was systematically donated by a major web analytics company beginning in 1996. Identify this organization and describe: (1) when it began donating its crawl data, (2) the archive that receives the data, (3) the specific name of the crawl data collection, (4) how the data flows into the archive (including any embargo process), and (5) whether this specific crawl dataset is currently publicly accessible.

Answer length: 200-300 words.

Identifies Alexa Internet as the organization that donates crawl data starting in 1996
Explains that Alexa Internet is a web analytics company whose crawl data supports large-scale web archiving used for researching historical topics such as early racing game websites

Width checklist

States that donations began in 1996
Identifies the Internet Archive as the recipient
Mentions integration into the Wayback Machine
Names the collection as the Alexa Crawls DR Crawl data
Explains that data is added after an embargo period
Clarifies that the specific crawl dataset is not currently publicly accessible

Examiner rationale

The question is anchored in the context of researching early racing game web history (domain relevance) but masks the target entity by describing it as a major web analytics company donating crawl data since 1996 (Deep logic filter). To answer fully, the respondent must aggregate multiple distinct facts: the organization’s name, start year, recipient archive, collection name, embargo process, and accessibility status (Wide aggregation). This ensures both correct entity identification and comprehensive detail retrieval.

Judgment

NONE

Score 1 - 0

First, Deep Logic: Both Agent A and Agent B correctly identify **Alexa Internet** as the organization donating crawl data beginning in 1996 and correctly connect it to the Internet Archive and Wayback Machine. Both pass the core entity check. Second, Width/Completeness: Both mention 1996, the Internet Archive, Wayback Machine integration, and a six‑month embargo. However, neither explicitly names the collection as the specific **“Alexa Crawls DR Crawl data”**, and both incorrectly state or imply that the dataset is publicly accessible (the checklist requires clarifying that the specific crawl dataset is not currently publicly accessible). Thus, both have similar WIDE shortcomings. Finally, User Experience & Presentation: Agent A provides clearer structure with bold labeling, numbered sections corresponding exactly to the five sub‑questions, and stronger scannability (BLUF-style organization). Agent B is more compressed and less explicitly segmented by the five required components, making it slightly harder to verify checklist coverage quickly. Because both are factually imperfect in similar ways, but Agent A delivers a more structured and user-friendly presentation, Agent A wins on formatting and usability rather than accuracy.

The organization is **Alexa Internet**, a web analytics and traffic-ranking company founded by Brewster Kahle and Bruce Gilliat in 1996. Alexa Internet has systematically donated its web crawl data to the **Internet Archive**, also founded by Brewster Kahle, which serves as the world's largest digital library and web preservation initiative [1][2]. **(1) When it began donating crawl data:** Alexa Internet began donating its crawl data to the Internet Archive in **1996**, the same year both organizations were founded. This donation relationship was established from the very beginning as part of Brewster Kahle's broader vision of preserving the web [1][3]. **(2) The receiving archive:** The data is donated to the **Internet Archive**, headquartered in San Francisco, California. The Internet Archive uses this data as a foundational component of its **Wayback Machine**, which allows users to browse archived versions of websites [2][3]. **(3) The specific crawl data collection:** The crawl data collection is known as the **"Alexa Crawls"** or more specifically the **"Alexa Internet Crawl Data"** within the Internet Archive's collections. It is housed under the archive's web collections infrastructure [3][4]. **(4) Data flow and embargo process:** Alexa Internet crawls the web continuously and donates the data to the Internet Archive. However, the data is typically subject to a **six-month embargo period** before it becomes accessible through the Wayback Machine. During this embargo, the crawl data is held but not made publicly available, allowing a buffer period before historical snapshots are released [3][5]. **(5) Public accessibility:** The Alexa Crawl datasets have been made **publicly accessible** through the Internet Archive's Wayback Machine for browsing archived web pages. Additionally, bulk research access to certain Alexa crawl datasets has been available to researchers, though access terms have varied over time, particularly after Amazon acquired Alexa Internet in 1999 [2][4]. ## References [1] Kahle, B.

The organization that systematically donated its crawl data beginning in 1996 is Alexa Internet [1]. Founded in 1996 and later acquired by Amazon, Alexa Internet was a web analytics company that used its web crawler to gather the data that became the foundational collection for the Internet Archive, which was also founded in the same year by Alexa's founder, Brewster Kahle [2, 3]. This collection of crawl data is most commonly known as the "Alexa Crawls." It does not have a distinct name separate from the Internet Archive's main web collection, which is accessed through the Wayback Machine [4]. The data flow involved Alexa's crawlers capturing web pages, with the full dataset being regularly donated to the Internet Archive. For a significant period, this process included a six-month embargo, meaning a crawled webpage would not appear in the public Wayback Machine until six months after its capture date [4, 5]. Alexa Internet was shut down on May 1, 2022, and it no longer contributes new crawl data [6]. The historical dataset donated by Alexa remains accessible to the public, but not as a raw, bulk-downloadable dataset. Instead, researchers and the public can access and analyze this information through the web-based interface of the Internet Archive's Wayback Machine, which allows for browsing specific archived websites on a URL-by-URL basis [4]. ## References [1] Kahle, B.
