LongEval 2024 Test Collection

The collection consists of queries and documents provided by the Qwant search Engine (https://www.qwant.com). The queries, which were issued by the users of Qwant, are based on the selected trending topics. The documents in the collection were selected with respect to these queries using the Qwant click model. Apart from the documents selected using this model, the collection also contains randomly selected documents from the Qwant index. All the data was collected over June 2023 and August 2023. In total, the collection contains 1,925 test queries. The set of documents consist of 4,321,642 downloaded, cleaned and filtered Web Pages. Translations of the webpages and queries into English will be added when available. The collection serves as the official test collection for the 2024 LongEval Information Retrieval Lab (https://clef-longeval.github.io/) organised at CLEF.
