Abstract： [Purpose/significance] This study aims to explore the differences between collaborative mode and individual mode of information search on search experience and search interaction, trying to understand the characteristics of collaborative information search from various angles.[Method/process] The experiment is designed based on books interactive retrieval platform (CLEF-Social Book Search). Sixteen independent and eighteen collaborative participants are recruited to the laboratory to complete different types of book search tasks. Users' interactions with the system during search are recorded through the backend server; while their search experience is recorded by questionnaires completed before and after the search. In data analysis, users' interactions and search experience are compared between two search modes.[Result/conclusion] (1) Search experience:Compared with individual searchers, collaborative searchers have better evaluation on experiment system function and higher evaluation on aesthetics, durability, novelty of the system, and participate in the search more intently. However, collaborative searcher felt a bit more frustrated and mentally taxing than individual searchers. (2) Search strategies:Compared with individual searchers, collaborative searchers make more decisions in the goal-oriented task, especially the decision of removing books from bookbag, which indicates collaborative searchers need to sort the books in the later stage. In the open-ended task, collaborative searchers spend more time before each decision than individual searchers, which is probably because of collaborative searcher's higher level of focus and participatory. This study helps understand about collaborative search through comparison with individual search, which may provide inspiration for collaborative search system design.

Abstract： [Purpose/significance] Information search extensively influence people's daily lives, and people tend to use search engine to find the information they need. However, the existing search system is better for supporting factual tasks search, and it is not satisfactory to support tasks such as searching in order to learn. In recent years, researchers have begun to pay attention to regarding search as learning, and try to evaluate the knowledge learning in search.[Method/process] For the purpose of mastering users' learning status in search thoroughly, in this paper, 32 students from Peking University were recruited to complete user experiment. User knowledge assessment method considering knowledge quantity and quality comprehensively was established in this paper. Based on this knowledge assessment method, user knowledge level in learning tasks before and after search was evaluated respectively, and the changes of knowledge level were investigated.[Result/conclusion]The research shows that users' performance on knowledge quantity dimension becomes more comprehensive and in-depth with the search completion, and has a significant improvement in the number of knowledge points, the number of knowledge facets, the breadth of knowledge facets and the depth of knowledge facets. At the same time, there are a number of relatively professional knowledge facets after searching. Some vague knowledge concept expressions before searching were expressed more clearly and explicitly after searching. In the dimension of knowledge quality, knowledge relevance, analysis and user opinion, the vast majority of users improve after searching. This paper provides a feasible way for researchers to evaluate user knowledge learning in information search from the perspective of multi-angle evaluation of knowledge status before and after searching.
