【摘要】：随着大数据、互联网、云计算等信息技术的发展与应用,科研用户的需求特征呈现新的发展趋势,图书馆等专业信息资源建设及服务机构面临新的机遇与挑战。在信息资源深度关联整合和集成化、知识化服务平台构建以及应用方面存在三个不足之处:(1)资源类型覆盖面相对较窄,资源关联整合深度不够;(2)缺乏一站式情景敏感的服务平台支撑;(3)缺少面向特定领域的成功的可复制的范例。针对以上三个问题,本文以农业科研用户为调查对象,以农业专业领域的信息资源整合与服务平台构建为研究目标,深入开展专业领域信息资源整合的关键技术与方法研究,研究构建面向科研用户的一站式学科知识服务平台,同时面向粮食安全领域进行实证研究。论文主要研究内容及取得的成果如下:(1)基于问卷调查与访谈相结合的方法,深入了解并分析了农业科研人员具体的资源与服务需求,进一步明确了农业科研用户在日常科研活动中获取、利用信息资源与服务的情况、需求和问题。(2)在分析农业专业领域资源体系基础上,研究设计了资源整合的流程和框架,并从基于元数据仓储、分类主题词表的知识组织、科研本体模型的语义关联和关联数据技术的整合发布等方面,进行了资源整合关键技术的集成应用探讨,初步实现了多源异构农业综合科技数字资源的知识组织与关联融合。(3)设计了农业专业领域知识服务平台体系架构,给出了平台建设流程,并详细阐述了农业专业领域知识服务平台的主要功能及实现的关键技术,通过主题分类标引、实体抽取与规范以及多维关联构建等后台功能实现了多源异构资源的管理与整合,设计并实现了统一资源搜索、学科资源导航、专家学术信息聚合、知识关联展示和学科态势分析等前端服务功能。(4)选择粮食安全领域开展了实证研究。经过领域资源抽取、平台实现搭建了粮食与食物安全专题服务平台,为粮食安全领域科研团队提供了一站式资源检索与获取和深层次知识服务,初步建立了“线上+线下”综合服务模式,获得了良好的用户使用反馈。本论文的创新点体现在:(1)综合集成应用了基于元数据、分类主题词表、科研本体模型和关联数据的资源整合关键技术,提出了一种多源异构农业综合科技数字资源的知识组织与关联融合的新技术方法,对构建形成富含语义关联关系的农业科技数据和知识网络,以及为各类资源的统一搜索和知识关联发现导航提供了技术方法支撑。(2)提出了集资源、技术、服务于一体的专业知识服务平台构建解决方案,实现了多源异构知识资源的统一发现与深度揭示,并面向粮食安全领域进行实践验证,解决了面向不同专业领域快速部署和应用服务的问题,是知识服务的创新实践。本文紧密结合我国农业专业领域科研人员具体的资源与服务需求情况、信息资源整合以及服务平台构建的研究与分析,形成了一些观点、方法、成果与思路,对我国信息服务的研究与实践具有一定的理论研究价值和实践指导意义。
[Abstract]:With the development and application of information technology such as large data, Internet, and cloud computing, the demand features of scientific research users present a new trend. The construction of professional information resources and service institutions such as libraries are facing new opportunities and challenges. The integration and integration of information resources, the construction of the knowledge-based service platform and its application exist. Three shortcomings: (1) the coverage of resource types is relatively narrow, and the depth of resource association integration is not enough; (2) lack of one-stop situational sensitive service platform support; (3) lack of a replicable model for the success of a specific field. In view of the above three problems, this article takes agricultural scientific research users as the investigation object and the information capital in the agricultural field. Source integration and service platform construction are the research objectives, and the key technologies and methods of information resources integration in the field of professional field are carried out. A one-stop disciplinary knowledge service platform for scientific research users is constructed, and the empirical research is carried out in the field of food security. The main contents and achievements of this paper are as follows: (1) based on the questionnaire The method of combining investigation and interview is used to understand and analyze the specific resources and service requirements of agricultural scientific research personnel, and further clarify the situation, needs and problems of the agricultural scientific research users in the daily scientific research activities and the use of information resources and services. (2) on the basis of the analysis of the resources system of agricultural professional fields, the research and design are designed. The process and framework of source integration are discussed from the aspects of metadata repositories, knowledge organization of Classified Subject Thesaurus, semantic association of scientific research ontology models and the integration and publication of related data technology. The integrated application of key technologies of resource integration is discussed, and the knowledge organization and the knowledge organization of multi source and heterogeneous agricultural comprehensive science and technology resources are realized. (3) the architecture of knowledge service platform in agricultural professional field is designed, the construction process of the platform is given, and the main functions and key technologies of the knowledge service platform in the field of agricultural specialty are elaborated in detail. The background functions such as subject classification indexing, entity extraction and specification and multi-dimensional association construction have been realized in many different sources. The management and integration of construction resources design and realize the front-end service functions of unified resource search, subject resource navigation, expert academic information aggregation, knowledge association display and subject situation analysis. (4) choose the field of food security to carry out an empirical study. Through the extraction of resources in the field, the platform has built a special service for food and food safety. The platform provides a one-stop resource retrieval and acquisition and deep knowledge service for the scientific research team in the field of grain security. It has initially established the "Online + offline" integrated service model and obtained good user feedback. The innovation points of this paper are as follows: (1) integrated integration should be based on Metadata, Classified Thesaurus, research ontology model. The key technology of resource integration of type and associated data is presented, and a new technology method is proposed for the integration of knowledge organization and association of multi source and heterogeneous agricultural comprehensive science and technology digital resources. It provides an agricultural technology data and knowledge network which is rich in semantic association, and provides navigation for the unified search and knowledge association of various resources. The technology and method support. (2) put forward the construction solution of the professional knowledge service platform which integrates resources, technology and service. It realizes the unified discovery and deep revelation of the multi source isomerism knowledge resources, and has carried out the practice verification to the field of grain security, and solved the problem of rapid deployment and application service facing the different professional fields. In this paper, the research and analysis of the specific resources and service requirements, the integration of information resources and the construction of service platform in the agricultural professional field of our country have formed some viewpoints, methods, results and ideas, which have a certain theoretical research value for the research and practice of information service in our country. Practical guiding significance.
