一种基于本体约束的知识抽取方法
An Approach of Knowledge Extraction Restrained by Ontology
 [PDF]

国杰,
Computer Science and Application (CSA) , 2011, DOI: 10.12677/csa.2011.13019
Abstract: 从知识的角度出发,提出一种基于本体约束的知识抽取方法:将领域本体中蕴含的逻辑信息转换为一个Alloy语言表示的模型,将命名实体识别和实体关系抽取的成果映射为解空间,接着将解空间里的每一个解转化为Alloy语言表示的断言语句,然后使用Alloy分析器来约简解空间,最终得到一个具有明确语义的完整知识实例。
In terms of knowledge view, an approach of knowledge extraction restrained by ontology is pro- posed in this paper. At first, translate a domain ontology into a model expressed by Alloy language and use the form of solution space to express the recognized entities and the recognized entity-relations which can be got when applying named entity recognition technology and entity relation extraction technology to coarse text block in turn. And then translate every solution of solution space into an assertion sentence which will be included in Alloy model. Next, reduce solution space by applying Alloy analyzer to the Alloy model. At last, a whole knowledge instance will be obtained.

Abstract: 针对传统模糊支付矩阵对策求解方法不能保证局中人的模糊值始终相同且求解复杂的问题,通过引入??-矩阵对策的概念,提出一种求解支付为梯形模糊数的矩阵对策线性规划方法.该方法中局中人双方的对策值始终相同,且此对策值的任意??-截集的上下界和局中人的最优策略容易通过求解导出的4个线性规划问题获得,特别地,可得到模糊对策值的显式表示.通过与其他方法的比较,表明了所提出的方法更具有效性和实用性.

杨靛青,
福州大学学报(自然科学版) , 2014,
Abstract: 提出支付值为直觉模糊集的多目标矩阵对策的定义及其解概念,通过建立一对辅助线性或非线性规划模型,计算得到局中人的最优策略. 数值实例表明了所提方法的有效性和实用性. 所提出的多目标直觉模糊集矩阵对策理论与方法既是对模糊对策理论方法的扩展和补充,也可为解决带有直觉模糊集信息的竞争性多目标对策问题提供新的途径.

考虑偏好冲突的多类评价信息群体决策方法
余高锋,
- , 2016,
Abstract: 针对偏好具有冲突性且权重信息完全未知的多类评价信息多属性群体决策问题, 提出了一种基于多目标决策的求解方法.首先, 建立以决策方案相对贴近度和决策成员偏好冲突程度为目标的多目标决策模型;然后,利用极小极大方法求解该多目标决策模型,得到各方案的属性权重和决策成员权重,根据计算各个方案的相对贴近度,进而确立方案优劣排序和最优方案; 最后, 通过数值例子的计算分析表明决策方法的有效性和合理性.
支付值为语言信息的矩阵对策求解方法
Method for solving matrix games with payoffs of linguistic information

杨靛青,
福州大学学报(自然科学版) , 2016, DOI: 10.7631/issn.1000-2243.2016.03.0301
Abstract: 在阐述语言评估标度定义及其运算法则、比较规则的基础上,提出了支付值为语言信息的矩阵对策定义及其解的概念,并研究了如何将求解局中人的极大-极小与极小-极大策略问题转化为求解一对辅助线性规划问题. 数值实例表明,所提方法是有效、实用的,所建立的支付值为语言信息的矩阵对策理论与方法既是对经典矩阵对策理论的发展,又可为解决其他带有模糊语言信息的对策问题提供新的途径.
The definition of linguistic labels and their operational laws as well as comparison laws are introduced. The definition of matrix games with payoffs of linguistic information and the concept of their solutions are given. The max-min and min-max strategies of two players are calculated by solving a pair of auxiliary linear programming models. A numerical example shows that the proposed method is effective and practical. The theory and method of matrix games with payoffs of linguistic information are not only an extension of those of classical matrix games,but also provide a new route for solving other matrix games with fuzzy linguistic information

Generalized Perturbation Results of Banach Frames and Atomic Decompositions on Banach Spaces
Banach空间上Banach框架和原子分解的扰动

,杨利军
数学物理学报(A辑) , 2009,
Abstract: Frame perturbation is one of active research contents in frame theory, but it was discussed on a Hilbert space in most literatures. This paper presents the perturbations of Banach frames and atomic decompositions on a Banach space, and obtains some more generalized perturbation results. It is shown that many known results are corollaries of our results.
