Query suggestions are a supporting tool in information search tools that help users query formulation. The purpose of this study was to prioritize the factors affecting the use of query suggestions through the Fuzzy Analytical Hierarchy Process (FAHP).

This study is an applied quantitative research that used a researcher-made questionnaire as instrument to collect the data. Five experts in data retrieval were asked to consider its items and comment on their relevance to the topic under study to ensure the validity of the questionnaire. The inconsistency rate was also used to verify the reliability of the questionnaire items. The questionnaire was distributed to 12 experts to gather the data for this study. To analyze the data, the FAHP was used in which the experts compared the pair of the main criteria, the sub-criteria of each criterion, and the final priority of the sub-criteria.

In this study, the criteria were classified into two categories: criteria related to the query suggestions system and criteria related to the user. Among the criteria related to the user criteria of domain knowledge and expertise, level of linguistic knowledge, and user’s query and among the criteria related to the query suggestions system the criteria of "source of creation of query suggestions (main and contextual), semantic features of query suggestions, and ease of use of query suggestions were the first to third priorities. Moreover, based on the final weight of each sub-criterion, the sub-criterion ‘the level of user’s expertise in the field of search’ was placed in the first priority; while ‘the difference between the user’s original language and the search information’ received the second priority; ’source of creation of query suggestions’ was in the third place; ‘providing semantic correlation between user’s queries and the query suggestions including broad, specific, related, and synonyms’ was placed in the fourth priority, and Providing a list of query suggestions in order of relevance placed in the fifth priority,  respectively.

The results of this study showed that ‘source of creation query suggestions’ and ‘domain knowledge and expertise’ was ranked first in prioritizing the main criteria. This finding suggests that the designers of the query suggestions should make a good choice of sources. Besides, prioritizing the factors affecting the use of query suggestions provides valuable information to designers and researchers in query suggestions. They can identify essential factors by prioritizing the factors affecting query suggestions and applying them in practice. Though the factors influencing the use of question suggestions are prioritized in this study, all factors are, in turn, important and should be considered when creating a question proposal to make high-quality suggestions.

The purpose of this study is identifying the influential factors in creating query suggestions. The query suggestion has become one of the most fundamental features of web search engines that help to user formulate the query and meet the information needs by providing possible keywords. In this research, in order to identify the effective factors in creating the query suggestions had used a systematic review. For this purpose, keywords of English and Persian language related to query suggestions have been searched in foreign scientific databases such as Science Direct, Emerald, Scopus, Online Willy, IEEE and internal databases of Magiran, Scientific Information Database of Jihad, and Cilivica to were found articles related with the effective contextual factors in creating query suggestions. In order to systematic review, method of Wright et al. (2007) was used that include seven steps: determination of  research question, determination of protocol, literature search, data extraction, quality appraisal, data analysis  and result. After search for Persian and English keywords and matching them with entry and exit criteria, 36 articles were selected to extract effective factors The findings of the systematic review in the field of the query suggestion show that five factors of location, time, user search sessions (including the user's current search session and user search history), hybrid factors, and other contexts were effective in creating query suggestions.Identification the influential factors in creating query suggestions helps researchers and those who interested in this domain to use appropriate contexts in accordance with the characteristics and conditions of the search tools and help the user to retrieve more relevant information.

To identify factors affecting the use of query suggestions in information search tools and proposing a model.

The factors were identified through the review of the literature, based on which a self-interaction questionnaire was designed and circulated among 10 experts to determine relationships between the factors.

Among the 13 factors identified through the review of the literature, demographic characteristics, search experience, domain knowledge and expertise, linguistic features, user's query, creativity, psychological and cognitional, the source of creation of query suggestions, contextual factors, semantic features of query suggestions, and structural characteristics of the query suggestions could increase the ease of use and improve the userperformance. The model presented “the source of generation of the query suggestion" was identified as the most influential factor.

Findings of this study could use when examining the performance, as well as in the design of query suggestion systems.
