UMass Genomics 2006: Query-Biased Pseudo Relevance Feedback
نویسنده
چکیده
Query-biased pseudo relevance feedback creates document representations for document feedback that aim to be more relevant to the user than using the entire document. Our submitted runs using querybiased feedback degraded performance compared to not using feedback. The cause of this degradation was the use of too many documents for feedback. Preliminary document retrieval experiments using fewer feedback documents found that query-biasing produced gains in the geometric mean average precision that non-biased feedback did not produce.

Many existing retrieval approaches treat all the documents in the collection equally, and do not take into account the content quality of the retrieved documents. In our submissions for TREC 2010 Web Track, we utilize quality-biased ranking methods that are aimed to promote documents that potentially contain high-quality content, and penalize spam and low-quality documents. Our experiments with...
متن کاملQuery expansion based on relevance feedback and latent semantic analysis
Web search engines are one of the most popular tools on the Internet which are widely-used by expert and novice users. Constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. Query expansion is a way to reduce this concern and increase user satisfaction. In this paper, a new method of query expa...
متن کاملUsing Concept-Based Indexing to Improve Language Modeling Approach to Genomic IR
Genomic IR, characterized by its highly specific information need, severe synonym and polysemy problem, long term name and rapid growing literature size, is challenging IR community. In this paper, we are focused on addressing the synonym and polysemy issue within the language model framework. Unlike the ways translation model and traditional query expansion techniques approach this issue, we i...

This paper describes our experiments in the TREC 2005 Genomics Track. For the ad-hoc retrieval task, we study synonym-based query expansion, as well as the effectiveness of a new pseudo-relevance feedback method which is derived from our recent work on semi-supervised learning. For the categorization task, we study various methods for estimating conditional class probability and determining the...
