Relevance Feedback by Exploring the Different Feedback Sources and Collection Structure
نویسندگان
چکیده
In HARD track of HARD 2005, we classify the 50 queries into 7 categories and make use of 3 kinds of feedback sources in various tasks. We find that the different kinds of queries perform differently in feedback tasks and the “CASE “ and “EVENT” queries are more sensitive to the feedback source. We also explore the internal structure of corpus and try to estimate the distribution of relevant documents within sub-collections. The experiments show that this technology is partly effective and the main existing problem is how to predict the distribution more precisely.
