We evaluate features derived from the user’s interaction with the search engine as well as features derived from the user’s level of interest in the task and level of prior knowledge in the task domain. In addition to user-interaction features used in pri

Adapting an expert task into a non-expert user task, thereby enabling the ordinary “crowd” to accomplish it, can be a useful approach. We studied whether a simplified version of an expert annotation task can be carried out by non-expert users. U

Erika Causa,Ricardo Fradique,Pietro Cicutak rely on query logs and are thus difficult to use in many circumstances. We propose a method for domain-specific synonym discovery that requires only a domain-specific corpus. Our method substantially outperforms previously proposed methods in realistic evaluations. Due to the difficulty of identif

The burden of interpreting these results, after combining with contextual information and description of relationships, lies with the user. In this
