基于情感分析混合模型的用户评论主题分析 ——以vivo手机为例

为了帮助商家了解用户需求和产品问题,进一步提升产品和服务质量,对vivo手机评论数据进行基于关键词的词云图分析、社会语义网络分析、舆情时间序列可视化分析,挖掘用户关注焦点与手机特征的内在联系和用户情感倾向趋势;然后对评论数据进行基于LDA的主题特征分析,继而提出一种基于Word2vec和SVM、LDA的混合算法模型,挖掘用户正向和负向情感评论的潜在主题,得到不同情感倾向下用户对vivo手机不同方面的反映情况。分析结果表明,基于混合算法的挖掘结果比基于关键词的可视化分析、基于LDA的主题分析更清晰,更具准确性,为商家提供的建议更有意义。

Gaps in the IFRS Conceptual Framework

Abstract

The stated purpose of the IFRS Conceptual Framework is to assist the IASB to develop Standards that are based on consistent concepts, and also to assist preparers to develop consistent accounting policies when Standards either do not apply or allow a choice of accounting policy. Yet, the Framework actually does surprisingly little to help the IASB (or preparers) determine which assets, liabilities, income and expenses should be recognised, and how they should be measured. The Framework’s focus on assets and liabilities implies that the accounting can, and should, be determined from the balance sheet. Yet, many current financial reporting requirements focus initially on the income statement, and so they are not so much derived from the Framework as instead in need of being reconciled back to it. At its heart, the problem here is that, while the Framework states that accrual accounting provides a better basis for assessing past and future performance than cash-based information, it does not explain why. To do so would require a conceptualisation of how entities’ business models are employed to create value, and of the strengths and limitations of accounting data in enhancing investors’ understanding of that value-creation. The lack of explanation of the purpose and informational objectives of accruals, how they relate to business models and how they cause the income statement and the balance sheet to interact are gaps in the Framework. Filling those gaps would provide a more robust, and natural, way for the IASB to develop recognition and measurement requirements in its Standards.     

Enterprise knowledge graphs with applications to continuous monitoring systems

Continuous monitoring systems generate continuous business intelligence by gathering text from a range of sources and typically storing that text information using snippets of text. Further, continuous monitoring systems derive information from those snippets, such as sentiment and new concepts emerging in the text, beyond the existing ontology and dictionaries. However, it is difficult for users to gather much additional information from large quantities of text snippets. As a result, this paper investigates introducing the notion of “knowledge graphs” into such systems and analyzes some of the potential applications and capabilities in business intelligence settings. As part of that analysis, this paper extends current-generation continuous monitoring systems to include knowledge graphs.

Conceptual and Procedural Knowledge

The ideas that underlie the title of this chapter have been part of a familiar debate in education, namely that of the contrast of content and process. In both science and mathematics similar arguments have taken place, and these debates represent a healthy examination of, not only the aims of science and mathematics education, but the teaching and learning issues, and as such they reflect the relative maturity of these subject areas. Even in technology education, which is still in its infancy as a subject, echoes of these debates exist and there are contrasts of approaches to the balance of process and content across the world. The 'debate' in technology is evangelical in nature, with for example, proponents making claims for problem-solving approaches as a basis for teaching with few accounts and almost no empirical research of what actually happens in classrooms. There is insufficient consideration of the learning issues behind this, or other proposals, and it is timely to turn our attention to student learning. This article examines the nature of technological knowledge and what we know about learning related to it. The article argues that learning procedural and conceptual knowledge associated with technological activity poses challenges for both technology educators and those concerned with research on learning.

Influence of salesperson characteristics and customer emotion on retail dyadic relationships

Retail salespeople often serve as a critical nexus between retailers and their customers. Salespeople can provide information and service that assist customers during the purchase process. Through buye–seller interaction, salespeople conceivably will influence how customers feel when shopping; in essence, salespersons are likely to have an impact on customers' emotions. Prior research has found that customer emotions have beneficial effects for both the store and the salesperson. Although previous work has considered the effect store environment has on customer emotions, no extant research has examined how customer emotions emerge after interacting with salespeople or what the outcomes of those emotions are. Consequently, this paper examines potential precursors of customers' emotions that arise during interaction with retail sales personnel, as well as consequences of those emotions. A conceptual framework is developed, propositions are posited, and retail management and research implications are presented.
