Discovering latent commercial networks from online financial news articles

Unlike most online social networks where explicit links among individual users are defined, the relations among commercial entities (e.g. firms) may not be explicitly declared in commercial Web sites. One main contribution of this article is the development of a novel computational model for the discovery of the latent relations among commercial entities from online financial news. More specifically, a CRF model which can exploit both structural and contextual features is applied to commercial entity recognition. In addition, a point-wise mutual information (PMI)-based unsupervised learning method is developed for commercial relation identification. To evaluate the effectiveness of the proposed computational methods, a prototype system called CoNet has been developed. Based on the financial news articles crawled from Google finance, the CoNet system achieves average F-scores of 0.681 and 0.754 in commercial entity recognition and commercial relation identification, respectively. Our experimental results confirm that the proposed shallow natural language processing methods are effective for the discovery of latent commercial networks from online financial news.     

认知视域下英语动词被动语态的原型及其语义特征研究

首先回顾英语动词被动语态的相关研究;然后从认知的角度基于原形范畴理论,借鉴语法符号隐喻,对被动语态的语言实例做具体分析,探求被动语态的原型及其语义特征。英语动词被动语态的原型式为其标记式＂be＋V-ed＂,其实质为施动性,原型语义为被动意义,且随着认知的发展,被动语义呈多样性和层次性：显性被动意义（真被动）、隐性被动意义（次被动）和隐性主动意义（假被动）。

金融犯罪种类划分及其特征揭示——兼论金融犯罪的此罪与彼罪之界分

金融犯罪作为一种新型经济犯罪,目前立法、司法部门及刑法学界对有关此类犯罪问题的研究尚不够全面、深入,其中对金融犯罪进行科学、合理分类并揭示其特征是亟需研究的基本问题之一。通过综合研析刑法理论界颇具代表性的客体、行为、混合等诸种分类法之优劣,紧密结合我国现行刑法所作的立法分类,提出以混合分类法为基本思路,依据金融犯罪所侵犯客体的相同性,兼顾犯罪方法的特殊性,作进一步的分类细化,以期形成符合我国实际的金融犯罪分类设想;同时,充分揭示不同类型金融犯罪构成特征,全面把握金融犯罪此罪彼罪界限所在,从而为金融刑事立法不断完善以及司法部门正确定罪量刑提供有利的依据。     

思维模式与大学英语写作

由于历史和社会发展的不同,中西思维存在着明显的差异,这种差异直接影响到跨文化写作的过程。该文拟从思维的角度探讨思维的差异对大学英语写作的影响,认为在学生写作的过程中,思维差异不仅影响着学生的语言表达,而且对语言的连贯性、逻辑性都有着一定的制约。     

CEO背景特征对公司风险承担的影响研究

以我国沪、深两市上市公司为研究对象,深入研究了CEO背景特征对公司风险承担的影响。研究表明:CEO年龄越大,越为保守和回避风险,倾向于降低公司风险承担;CEO任期越长,其专用性人力资本和管理防御程度越高,公司风险承担水平越低;CEO教育程度与公司风险承担显著负相关,当CEO在其他单位兼职时,公司风险承担水平相对较低。而CEO性别、职称对公司风险承担并没有显著的影响。文章为我们更好地理解上市公司的风险承担行为及CEO等高管的选拨与任命具有一定的启示意义。

Do the physical facilities in restaurants match older Americans’ preferences?

This study investigated restaurants’ response to the aging population’s preferences. Gaps between previously identified preferences and current restaurant design were examined. The observational survey assessed: parking and outside accessibility, comfort and inside accessibility, menu readability, and restrooms. Occasional gaps were found even though restaurants were generally well-designed. Casual dining restaurants were more likely to meet consumer preferences as to the exterior, seating, and service. Limited-service restaurants better met preferences for the bathrooms, lighting, and sound. This information may be helpful when building or remodeling restaurants and may help restaurants to attract older customers.     

A proposed configurable approach for recommendation systems via data mining techniques

This study presents a configurable approach for recommendations which determines the suitable recommendation method for each field based on the characteristics of its data, the method includes determining the suitable technique for selecting a representative sample of the provided data. Then selecting the suitable feature weighting measure to provide a correct weight for each feature based on its effect on the recommendations. Finally, selecting the suitable algorithm to provide the required recommendations. The proposed configurable approach could be applied on different domains. The experiments have revealed that the approach is able to provide recommendations with only 0.89 error rate percentage.
