CALL FOR PAPERS: Special Session on Agricultural Metadata & Semantics

The aim of the Special Session on Agricultural Metadata and Semantics of MTSR'07 is to bring together researchers and practitioners that are working on agricultural knowledge production, organization, and exchange from a Semantic Web perspective.

  粮农组织农业信息管理标准活动伸展到Wikipedia

Wikipedia是世界上发展最迅速、合作、内容开放的在线百科全书。2005年底时每天访问人数达600，000；有200种语言400多万篇文章。Wikipedia惊人的成功不仅仅是因为其“开放性编辑”政策，或收集了有关可以想象的所有主题的高水平资料。它代表了相信某个网络哲理的全球团体。许多追随者是相同领域的顶尖专家；他们把他们的专业知识免费输入一个开放性档案库。

粮农组织推动和促进世界农业界信息管理标准的工作反映在Wikipedia 网页上。目前有关Wikipedia的主要工作有：

• 农业元数据元素集 ((AgMES)：粮农组织为描述和发现农业信息资源开发的元数据标准；
• 农业本体服务(AOS) ：为构建和统一多种语言农业术语供任何数量的农业系统使用并提供其它一些服务的参考资料行动，目的是提高农业系统之间的互操作性；
• 粮农组织多种语言农业术语汇编(AGROVOC)：覆盖农、林、渔、粮食和有关领域（如环境）所有主题词汇；

  FAO Case Study on semantically navigable “Food, Nutrition and Agriculture Journal” is published by W3C

One current application of the Semantic Web in the agricultural domain is the AGRIS Application Profile (or AGRIS Application Ontology) consisting of concepts describing document-like information objects such as title, creator and publisher. Used in conjunction with AGROVOC (the multilingual agricultural thesaurus), it creates an information retrieval application that performs query expansion by exploiting the relationships between concepts.


One major advantage of an ontology-based system over a traditional one lies in its ability to perform concept-based searches. The FNA (Food Nutrition and Agriculture) portal is a successful example of how the use of ontologies can improve search results. Metadata about each article in the FNA Journal (available in FAO’s Corporate Document Repository and the FAO’s bibliographical database) were combined and converted to a single RDFS format. The result is a portal that allows for concept-based as well as multilingual searches.


Further studies are being carried out to further exploit semantic relationships and develop user friendly services.
