The Cross-Language Evaluation Forum (CLEF) promotes R&D in multilingual information access (MLIA) by (i) developing an infrastructure for the testing, tuning and evaluation of information retrieval systems operating on European languages in both monolingual and cross-language contexts, and (ii) creating test-suites of reusable data which can be employed by system developers for benchmarking purposes.

The CLEF AdHoc-News Test Suites (2004-2008) contain the data used for the main AdHoc track of the CLEF campaigns carried out from 2004 to 2008. This track tested the performance of monolingual, bilingual and multilingual Information Retrieval (IR) systems on multilingual news collections.

The CLEF Test Suite is composed of:
• News Data Collections
• Topics
• Guidelines
• Relevance assessments
• Official campaign results
• Working notes papers
