dc.description.abstract | Retrievability is a measure of access that quantifies how easily documents can be found using a retrieval system. Such a measure is of particular interest within the recall oriented retrieval domains such as patent or legal retrieval. This is because if a retrieval system for these retrieval domains makes some documents hard to find then professional searchers would have a difficult time when retrieving these documents. One main limitation of retrievability analysis is that it depends upon the processing of exhaustive number of queries. This requires large processing time and resources. In order to handle this problem, in this paper we use document features based approach in order to estimate the retrievability ranks of documents. In experiments, the strong correlation between features and retrievability scores on different collections confirms that it is possible to estimate the retrievability ranks of documents without processing queries. One major advantage of this approach is that it requires fewer resources, and can be computed more quickly as compared to query based approach. While, on the other hand, one major disadvantage of this approach is that it can only estimate the retrievability ranks of documents, but cannot calculate how much there is retrievability inequality (retrieval bias) between the documents of collection. | en_US |
