In this paper, we propose a method for utilizing less relevant documents to relevance feedback in document retrieval.
If any relevant documents are not found and only less relevant documents are found in the initial retrieval, the user classify each less relevant document into two types according to whether it is relatively close to the desired document or not.
The search query is modified by the difference between the averages vectors of two sets of less relevant documents, and another search using new query will be invoked.
Experiments show that our method can find relevant documents earlier than the Rocchio's algorithm. |
