What is TREC? [SEP] The information retrieval community has emphasized the use of test collections and benchmark tasks to measure topical relevance, starting with the Cranfield Experiments of the early 1960s and culminating in the TREC evaluations that continue to this day as the main evaluation framework for information retrieval research. [SEP] How did they influence modern initiatives? [SEP] In the face of these criticisms, some researchers have argued that brick-and-mortar experiments are just as affected by these problems, if not more so. [SEP] What are some criticisms of the experiments? [SEP] With the help of NSF funding, Cleverdon started a series of projects in 1957 that lasted for about 10 years in which he and his colleagues set the stage for information retrieval research.

What are some recent tasks? [SEP] The test collections developed at TREC are useful not just for (potentially) helping researchers advance the state of the art, but also for allowing developers of new (commercial) retrieval products to evaluate their effectiveness on standard tests.

What about online ones? [SEP] The evaluation measures of an information retrieval system is the process of assessing how well the search results satisfied the user's query intent. The metrics are often split in to multiple categories. Online metrics measure actual users' interactions with the search system. Offline metrics measure the relevance of the search engine by having expert judges measure how likely each result (or the SERP page as a whole) is to meet the information needs of the user.
