中文摘要:
      信息聚合正成为信息组织与检索领域的研究热点。在对现有信息聚合相关概念进行阐释的基础上,本研究提出以情景、关系和对象作为信息聚合概念的主要构成,并依此对当前国内外信息聚合的典型应用和研究前沿进行梳理,依据聚合的情景、关系和信息粒度大小,将现有研究和实践中相关聚合模式归纳为情景聚合、语义聚合、引用聚合、社会网络聚合和粒度聚合五种主要模式和十二种表现形式;在此基础上提出多模式综合的深度聚合发展趋势:情景是决定关系和粒度等其他聚合要素的依据,情景的细化和深入研究势必带来多模式的综合应用,概念和实体、引用和社会网络等关系正被综合运用,而对不同粒度信息对象的聚合则是情景和关系聚合的落脚点。图1。参考文献96。
英文摘要:
Aiming at bringing the dispersive information into a universal interface according to users needs, information aggregation is becoming a new realm in the field of information organization and information retrieval. Focusing on the concept of information aggregation as the starting point, this paper proposes the core elements of information aggregation as the conceptual framework to classify the typical cases of information aggregation researches and practices into several paradigms. The cases related to information aggregation are collected from the following sources: the research projects from the iSchools worldwide, the international conference papers in the field of LIS from 2009 to 2013,the research papers from five LIS international journals (including: Journal of the American Society for Information Science and Technology, Journal of Documentation, Journal of Information Science, Information Processing and Management, Scientometrics) from 2009 to 2013, the research projects sponsored by both the National Natural Science Foundation and the National Social Science Fund in China, and the thesis or dissertations from CNKI. Within this range, this paper selects the typical cases according to data integrity and representativeness.
After clarifying the concepts of information aggregation, this paper proposes the core elements of information aggregation as context, relationship and information objects. The main paradigms of information aggregation are classified as contextual aggregation, semantic aggregation, citation aggregation, social network aggregation, fine-grained aggregation;their manifestations include aggregation of situational information for events, aggregation relying on situational information, personal information aggregation relying on user models, aggregation relying on semantic networks, aggregation relying on citation or web links, aggregation relying on social network, aggregation based on information units, aggregation based on information fusion and aggregation based on knowledge units. Eventually, this paper proposes the development trend of integration of the five paradigms, i.e. “in-depth aggregation”. Among the core elements of information aggregation, the context of aggregation would serve as the basis of the other two elements, and the development of which would lead to the integratively application of multi-paradigms; the relationships for aggregation relying on concept and entities, citation and social network are utilized integratively in information aggregation; multi-granularity aggregation of information objects would be the result of aggregation relying on context and relationship.
The originality of this paper lies in that it proposes the conceptual framework of information aggregation through clarification, interpretation and expansion of existing concepts or definitions,the main paradigms of information aggregation and their manifestations based on this conceptual framework; it further proposes the development trend of in-depth aggregation with multi-paradigm integration. 1 fig. 96 refs.
