Using a Medical Thesaurus to Predict Query Difficulty

Estimating query performance is the task of predicting the quality of results returned by a search engine in response to a query. In this paper, we focus on pre-retrieval prediction methods for the medical domain. We propose a novel predictor that exploits a thesaurus to ascertain how difficult queries are. In our experiments, we show that our predictor outperforms the state-of-the-art methods ...

Using Coherence-Based Measures to Predict Query Difficulty

We investigate the potential of coherence-based scores to predict query difficulty. The coherence of a document set associated with each query word is used to capture the quality of a query topic aspect. A simple query coherence score, QC-1, is proposed that requires the average coherence contribution of individual query terms to be high. Two further query scores, QC-2 and QC-3, are developed b...

Can Body Mass Index Predict the Difficulty of Colonoscopy?

Open Access Colonoscopy has been widely used as a screening modality for colorectal cancer and in the treatment of colon disorders. Generally, colonoscopy is safe, well tolerated, and recognized as a standard diagnostic and treatment method for colon disorders. Cecal intubation (CI) is one of the proposed quality indicators for colonoscopy.

Identifying the Task Variables That Predict Object Assembly Difficulty

OBJECTIVE We investigated the physical attributes of an object that influence the difficulty of its assembly. Identifying attributes that contribute to assembly difficulty will provide a method for predicting assembly complexity. BACKGROUND Despite object assembly being a widespread task, there has been insufficient research into information processing and cognition during assembly. The lack ...
