中文摘要:摘要近几年,工作任务在信息行为研究领域受到越来越广泛的关注,很多学者从不同角度对工作任务的定义进行诠释。尽管学者们使用了很多不同的术语,但是他们普遍认为,任务是影响信息搜寻行为的最重要的因素。任务可以是专业活动、研究活动、教育活动、娱乐活动或者其他的个人活动。于是,很多学者认为,任务是用户进行信息搜寻的原动力,是影响信息搜寻和信息检索的主要因素。本文从任务驱动的角度来研究化学研究者的信息搜索行为,探讨化学研究者的工作任务是如何影响信息搜索任务的,并进一步讨论化学研究者在日常科研中遇到的信息搜索方面的问题,具体在哪方面存在障碍,以及对目前使用的信息源有哪些建议。本文首先根据分面任务分类法来设计问卷,用以了解化学研究者的工作任务的不同的方面,和在课题前期、中期和后期的信息检索任务的不同方面。通过问卷收集到80份有效的数据,然后通过初步统计分析,得到化学研究者在进行科学研究时的工作任务和信息搜索任务的大体情况;再通过SPSS统计分析,得到工作任务和不同阶段的信息搜索任务的相互影响关系。通过问卷,收集到化学研究者关于工作任务和信息检索任务的大量数据,为后续的初步统计分析和SPSS研究分析打下数据基础;通过深度访谈,了解到化学工作者科研任务的具体情况、在做科研的不同阶段分别需要什么样的信息检索以及不同阶段的信息检索分别会遇到什么样的问题。本研究希望能总结出化学研究者信息搜寻的特点,能够给化学文献检索系统的改善提出建议。 
英文摘要:Abstract In recent years, more and more scholars have paid attention to work task in the field of information behavior, they have explained work task from different aspects. They generally believe that work task is the most important influence factors of information search behavior. The task can be professional activities, research activities, education, entertainment or other personal activities. Thus, many scholars believe that the task is the motive factor of users to search information, and which is the main factor to influence information search and information retrieval. From the perspective of task driven, in this paper we study on the chemical information search behavior to explore that how chemical research task can affect the information search task. And further discuss the problems and obstacles that chemistry researchers encourter in daily scientific research, then we will make some useful suggestions for chemical databases. At the beginning, we use A faceted classification of task to design a questionnaire to understand different aspects of chemical research tasks and previous study, the mid and last stages of information retrieval tasks. We have collected 80 valid data by questionnaire, then through the preliminary statistic analysis, we get the specific data about the work task and research task of chemical researchers when they are doing their research; through the analysis of the statistics of SPSS, we get the mutual influence relationship of tasks and different stages of information search tasks. We get a large number of information about the work task and information search task of chemical researchers through the questionnaire, and lay the foundation for the follow-up statistical analysis. Through in-depth interviews, we can understand how the chemical researchers do their research and what kind of information do they need during different stages of information search. We hope to summarize the characteristics of the information search behaviors of chemical researchers, and put forward suggestions to improve the chemical literature retrival system.
