Natural spatial query language is an important research field of spatial database and intellectualized GIS. The paper discusses the interpreting mechanism of natural spatial query language with spatial knowledge bases which include spatial dictionary, spatial query sentence pattern, grammar rule, spatial semantics, etc. The natural language in the paper especially refers to Chinese. Through the interpreting...
With the increasing popularity of Internet and the diversity of information obtaining technologies, the amount of quickly growing information has gone beyond our imaginations. Many techniques were presented to help users to find the desired information from large data set quickly and accurately, automatic summarization is an effective approach. In this paper, after careful investigation, existing...
Creating plenty of ontologies is a crucial task for realizing the Semantic Web vision. Techniques of learning ontology from text are far from mature because of the limitations of natural language understanding. However, discovering concepts and relations from tables is much easier. In this paper, we proposed a novel approach to generate ontologies from web tables. Our approach can be described as...
Traditional agricultural knowledge service is based on keyword rather than content, the recall rate and precision rate cannot to be improved. The knowledge representation based on semantic web can truly achieve the semantic-level knowledge service. This paper analyzes the status of agricultural knowledge service system and points out its shortcomings, elaborates semantic web technologies, studies...
In the current thinking of the Chinese text clustering, most clustering algorithms are limited by the data's scalability and the results' interpretability. This paper presents an efficient Chinese text clustering method based on semantic concepts. This method, proceeding from the text itself, by using classified hierarchy Subject Word in Thesaurus of Modern Chinese, extracts the conceptional tuple...
Recently the use of ontologies is becoming more widly spread, however building ontologies is remains a challenging issue, especially for maritime domain, which has no structural resources in existence. In this paper, we propose a method that is based on Formal Concept Analysis(FCA) and illustrate this method on some examples. Formal concept analysis is a theory of data analysis which identifies conceptual...
In order to improve the platform portability and efficiency of the web services composition methods, the web services composition approach based on model-driven is put forward, and the composition process is divided into service selection, composition definition, composition analysis, model transformation. The MWSC (model-driven web services composition) platform is designed. Finally taking advantage...
An intelligent content adaptation system taking semantic adaptation method is built to provide good personalized service for user. Compared with some website using web mining and collaborative Filtering technology, in this system, the intelligence comes from the knowledge service providing by CBKMF(ontology-Cloud based knowledge manage framework), in which knowledge modeling, managing, data-mining...
The focus of the software development technology based on components is the identification and assembly of components. The formalized descriptions of the component, including data and computing descriptions, are studied using the theory and method of category. The focus is the unified description of component computing (i.e. component function). The unified description of the component in a certain...
This paper focuses on the mechanism of service retrieving, including its semantic problem. It first compares the differences between the retrieving model of traditional digital library and that of which based on semantic grid. And then it utilizes both the information grid technology and semantic technology in digital library area to resolve the interoperability issues and retrieval performance bottlenecks...
