How Does Domain Expertise Affect Users' Search Interaction and Outcome in Exploratory Search?

Jiaxin Mao, Yiqun Liu, Noriko Kando, Min Zhang, Shaoping Ma
2018 ACM Transactions on Information Systems  
Previous researches categorize these learning-related searches as exploratory searches, because they are often open-ended and multi-faceted, in which the user usually submits multiple queries iteratively  ...  In this position paper, we propose to conduct a user study to investigate whether and how users' domain expertise affect their search processes in exploratory searches.  ...  Previous works on query reformulation strategy study the reformulation patterns [4] , why the user adds or removes terms in query reformulation [5] , the sources of query terms [2, 12] , and the relationship  ...

Yan Zhang
2013 Journal of the Association for Information Science and Technology  
Nineteen students participated in the study, and each performed 12 specific tasks.  ...  could be implemented to help users reformulate queries; and the search results page should be reconceptualized as a place for accessing answers rather than documents.  ...  Query reformulations were not as pervasive and complex as those observed in Zhang et al. (2012) when users performed exploratory tasks.  ...

Voice Search and Typed Search Performance Comparison on Baidu Search System [article]

Hanqing Huang, Kezia Irene, Nahyun Ryu
2019 arXiv   pre-print
This paper is a pilot study to compare the search performance of people using voice search and typed search using Baidu search system.  ...  Afterward, we analyzed 8 people who had a middle to advanced searching ability by their behaviors, search results, and average query length.  ...  For designing search tasks more adequate to our research question, the query tasks should be developed with certain correct answer.  ...

A study of children's search query formulation habits

Nicholas Vanderschantz, Annika Hinze
2017 HCI 2017  
As a result of this study, we identified query-creation and query-reformulation strategies that children use.  ...  The strategies children use for digital information search in educational settings are rarely explored.  ...  Because natural language questions required least reformulations, we suggest educating children to use natural language questions or natural language sentences.  ...

2015 Proceedings of the 38th International ACM SIGIR Conference on Research and Development in Information Retrieval - SIGIR '15  
Based on the public API of a popular search engine, we demonstrate how query suggestion candidates can be ranked according to traces of user attention and interest, resulting in significantly better performance  ...  In this paper, we study query refinement using eye-tracking in order to gain precise and detailed insight into which terms the user was exposed to in a search session and which ones they showed a particular  ...  the 2006 and 2007 editions of the TREC Question Answering Track's complex interactive QA task [28] .  ...

Automatic Identification and Contextual Reformulation of Implicit System-Related Queries

Adam Fourney, Susan T. Dumais
2016 Proceedings of the 39th International ACM SIGIR conference on Research and Development in Information Retrieval - SIGIR '16  
We show that such queries: (1) can be detected with high precision, (2) are common, and (3) can be automatically reformulated to substantially improve retrieval performance in these fall-through scenarios  ...  We report that, in this environment, users frequently ask questions that implicitly pertain to the systems or devices from which they are searching (e.g., asking: [how do I take a screenshot]).  ...  In more practical terms: across all queries, the median relevance of the topmost search result was 4 (excellent) in all treatment conditions, but was only 2 (fair) for the unaltered query baseline.  ...

2018 Journal of Computer Science  
The main goal of this new model is to enrich the question by reformulating it into similar meaning queries with additional information and hence for improving question answering process.  ...  Query expansion is an approach which is used to extend question key words with new related words that are not included in question.  ...  These reformulated query terms are used to select and retrieve question answer pairs that best match the reformulated question.  ...
