Abstract
Crowdsourcing is a task-solving model in which human crowd is hired to solve a particular task. During the crowdsourcing process, the crowd selection is performed in order to select appropriate crowd workers for a specific task; without appropriate selection of crowd workers, the process of crowdsourcing is aimless. The main goal of this paper was to identify the features of crowd in crowdsourcing activity, reasons behind crowd participation in the activity of crowdsourcing, and the existing techniques that were utilized for crowd selection in crowdsourcing. Search strings with corresponding keywords were used to capture relevant studies related to crowdsourcing, and crowd selection was classified under conference papers, journal articles, proceedings, and book chapters. 81 relevant studies are selected from 7 digital data repositories using a search strategy. In crowdsourcing practices, crowd selection was considerably addressed. Nonetheless, it has been noticed that the selection is based only on a single crowd worker attribute such as confidence, past success, efficiency, and experience. For the efficiency and effectiveness of the crowdsourcing operation, crowd selection on multicriteria features is essential.

We addressed the problem of crowd selection in crowdsourcing
One of the key contributions of our research is to illustrate the various multiple features of the crowd. Another contribution of the review is to identify the various reasons of crowd participation, and the third contribution of this study is to capture various selection methods used for crowd selection
Summary
Crowdsourcing is a task-solving model in which human crowd is employed for solving complex tasks [1]. It is an online activity that is used for gathering the collective knowledge, skills of people in order to complete an ordinary task [2]. An organization outsources different types of tasks to a huge crowd using an open call. E term crowdsourcing was first coined by Jeff Howe; in the magazine, Wired, he defined it as “the act of taking a job traditionally performed by a designated agent (usually an employee) and outsourcing it to an undefined, generally large group of people in the form of an open call.”. E tasks are posted on a platform and the crowd participates for performing various types of tasks [6, 8,9,10]. Participants with various backgrounds, levels of qualification, different
