An information content and Set of Common Superconcepts-Based Algorithm to Estimate Similarity between Concepts of Ontologies

引用

Open Journal of Applied Sciences 2023年第11期13卷 1896-1909页

作者： Gbede Sylvain Gbame Maho Wielfrid Morie Konan Marcelin Brou Institut National Polytechnique Félix Houphouë t-Boigny Yamoussoukro C&#244te d’Ivoire Laboratoire de MathématiquesInformatique Université Nangui Abrogoua Abidjan C&#244te d’Ivoire

Ontologies have been used for several years in life sciences to formally represent concepts and reason about knowledge bases in domains such as the semantic web, information retrieval and artificial intelligence. The exploration of these domains for the correspondence of semantic content requires calculation of the measure of semantic similarity between concepts. Semantic similarity is a measure on a set of documents, based on the similarity of their meanings, which refers to the similarity between two concepts belonging to one or more ontologies. The similarity between concepts is also a quantitative measure of information, calculated based on the properties of concepts and their relationships. This study proposes a method for finding similarity between concepts in two different ontologies based on feature, information content and structure. More specifically, this means proposing a hybrid method using two existing measures to find the similarity between two concepts from different ontologies based on information content and the set of common superconcepts, which represents the set of common parent concepts. We simulated our method on datasets. The results show that our measure provides similarity values that are better than those reported in the literature.

Identifying M&A targets and the information content of VC/PEs

引用

China Journal of Accounting Research 2018年第1期11卷 33-50页

作者： Qingquan Tang Wenfei Li Sun Yat-sen Business School Sun Yat-sen University School of Economics and Statistics Guangzhou University

The information gap in the M&A market hinders acquirers from effectively identifying high-quality targets. We examine whether VC/PEs convey information content in the M&A market and whether acquirers can use such information to identify high-quality targets. We show that VC/PEs have significant information content and can signal high-quality target companies via ‘‘certification". When acquirers lack acquisition experience and targets are located in inferior information environments, VC/PE ‘‘certification" is more *** better reputation a VC/PE has, the more information it conveys. Syndicate VC/PEs convey stronger information than independent VC/PEs. We also find that acquirers do not pay higher premiums for high-quality targets. Overall, our results suggest that VC/PEs have value relevance in the M&A market,confirming their ‘‘certification" role. We present means for acquirers to select high-quality targets and investors to build efficient portfolios.

债券市场安全涉及国家的金融安全，近年来因我国债券违约频发而备受关注。基于我国债券市场特征、财务困境和制度经济学理论，引入财务信息和非财务信息变量并使用传统统计方法和机器学习方法可构建一批债券违约预警模型。研究发现：第一，对比传统统计方法构建的债券违约预警模型，基于机器学习构建的债券违约预警模型具有更高的预测准确度。第二，在使用财务信息变量的基础上引入非财务信息变量，债券违约预警模型的预测准确度大幅提高，表明非财务信息为预警模型提供了有效的增量信息。具体来说：(1)作为债券市场重要的“看门人”，审计和评级机构都能提供债券违约的预警信息，但违约前一年审计意见提供的预警信息的重要性高于信用评级提供的预警信息；(2)发债企业的所有制、上市状况及其所属地区的经济与社会环境如社会资本和营商环境对于债券违约预警具有重要作用；(3)货币政策信息对于债券违约预警也具有重要作用；(4)预警模型帮助投资者大幅降低“踩雷”的概率，极大提高了债券投资的安全性。

Integrated Semantic Similarity Model Based on Ontology

引用

Wuhan University Journal of Natural Sciences 2004年第5期9卷 601-605页

作者： LIUYa-Jun ZHAOYun DepartmentofComputerScienceandEngineering.SoutheastUniversity Nanjing210096.JiangsuChina

To solve the problem of the inadequacy of semantic processing in the intelligent question answering system, an integrated semantic similarity model which calculates the semantic similarity using the geometric distance and information content is presented in this paper. With the help of interrelationship between concepts, the information content of concepts and the strength of the edges in the ontology network, we can calculate the semantic similarity between two concepts and provide information for the further calculation of the semantic similarity between user’s question and answers in knowledge base. The results of the experiments on the prototype have shown that the semantic problem in natural language processing can also be solved with the help of the knowledge and the abundant semantic information in ontology. More than 90% accuracy with less than 50 ms average searching time in the intelligent question answering prototype system based on ontology has been reached. The result is very satisfied.

Comparative Analysis of Transcription Start Sites Using Mutual information

引用

Genomics, Proteomics & Bioinformatics 2006年第3期4卷 189-195页

作者： D. Ashok Reddy Chanchal K. Mitra Department of Biochemistry University of Hyderabad Hyderabad 500046 India.

The transcription start site （TSS） region shows greater variability compared with other promoter elements. We are interested to search for its variability by using information content as a measure. We note in this study that the variability is significant in the block of 5 nucleotides （nt） surrounding the TSS region compared with the block of 15 nt. This suggests that the actual region that may be involved is in the range of 5-10 nt in size. For Escherichia coli, we note that the information content from dinucleotide substitution matrices clearly shows a better discrimination, suggesting the presence of some correlations. However, for human this effect is much less, and for mouse it is practically absent. We can conclude that the presence of short-range correlations within the TSS region is species-dependent and is not universal. We further observe that there are other variable regions in the mitochondrial control element apart from TSS. It is also noted that effective comparisons can only be made on blocks, while single nucleotide comparisons do not give us any detectable signals.

STUDY ON UNIFYING AXIOMATIC DESIGN AND ROBUST DESIGN

STUDY ON UNIFYING AXIOMATIC DESIGN AND ROBUST DESIGN

引用

第七届海内外青年设计与制造科学会议

作者： Xiao Renbin and Cheng Xianfu CAD Center Huazhong University of Science and Technology China School of Mechanical Engineering East China Jiaotong University China

＜正＞Axiomatic design is top down tool for design and provides a guide framework for designers during the design process. Robust design is an effective method that can lead to improving product quality at low cost. This method allows the designers to explicitly consider and control the effects of variability in design variables and parameters on designs. In the view of axiomatic design, minimizing both the variance and the difference between the mean and the target in robust design is the same as minimizing the information content in axiomatic design. It is therefore natural to unify axiomatic design and robust design. The connection between them is analyzed. That the robustness concept is identical and the idea of improving design quality of the product is uniform has been pointed out and mathematical relationship has been established between them. In the end, a design of liquid dynamic sliding bearing illustrates that a design of minimizing the information content is in essence a robust design.
