Let’s do an experiment. Here’s a TREC topic that specifies an information need
Description: What are the laws dealing with the quality and processing of food, beverages, or drugs?
Narrative: A relevant document will contain specific information on the laws dealing with such matters as quality control in processing, the use of additives and preservatives, the avoidance of impurities and poisonous substances, spoilage prevention, nutritional enrichment, and/or the grading of meat and vegetables. Relevant information includes, but is not limited to, federal regulations targeting three major areas of label abuse: deceptive definitions, misleading health claims, and untrue serving sizes and proposed standard definitions for such terms as high fiber and low fat.
Below are links to four documents that have been identified by some systems as being relevant to the above topic. Are they?
