Why this is here

The owner suspected at U21 that agent harnesses rediscover older information retrieval. A21 cited relevance feedback and the query-drift problem. This is a standard source for query drift, which TERM-056 distinguishes from question drift and CLAIM-301 builds on. Rocchio’s relevance feedback (1971) is the older source and is not registered, having no DOI. The reading confirms that query drift, in this paper, is the query moving off a topic that stays fixed (NOTE-1460).
