HitFraud: A Broad Learning Approach for Collective Fraud Detection in Heterogeneous Information Networks

On electronic game platforms, different payment transactions have different levels of risk. Risk is generally higher for digital goods in e-commerce. However, it differs based on product and its popularity, the offer type (packaged game, virtual currency to a game or subscription service), storefront and geography. Existing fraud policies and models make decisions independently for each transaction based on transaction attributes, payment velocities, user characteristics, and other relevant information. However, suspicious transactions may still evade detection and hence we propose a broad learning approach leveraging a graph based perspective to uncover relationships among suspicious transactions, i.e., inter-transaction dependency. Our focus is to detect suspicious transactions by capturing common fraudulent behaviors that would not be considered suspicious when being considered in isolation. In this paper, we present HitFraud that leverages heterogeneous information networks for collective fraud detection by exploring correlated and fast evolving fraudulent behaviors. First, a heterogeneous information network is designed to link entities of interest in the transaction database via different semantics. Then, graph based features are efficiently discovered from the network exploiting the concept of meta-paths, and decisions on frauds are made collectively on test instances. Experiments on real-world payment transaction data from Electronic Arts demonstrate that the prediction performance is effectively boosted by HitFraud with fast convergence where the computation of meta-path based features is largely optimized. Notably, recall can be improved up to 7.93% and F-score 4.62% compared to baselines.Comment: ICDM 201

INDUSTRIAL ENLARGEMENT AND COMPETITIVENESS INDEX

Over the last decade Slovenia has achieved clear and positive macro-economic results that have placed it among the most sucessful transitions countries. The basic indicators show that it has been integrating and catching up with European Union member states at an ever increasing pace. Despite this, the challenges of a global economy-where only innovation and entrepreneurship can compete succesfully, and the relative lag in the competitive capacity of our economy behind numerous other countries in the world rankings, require drastic changes to be made to Slovenia’s economic structure to adopt as much as possible to the demans of the knowledge based economy. That means the transformation from an economy with low added value whose competitiveness is based on low operative costs into an economy based on production and service activities whose competitive advantages are high added value, quality, innovation and entrapreneurship. Entrepreneurship and the diffusion of innovation, which considerably increase the speed at which new high-quality and low cost products replace existing products, are two driving forces of the knowledge based economy and they are changing the economic structure of leading countries....national competitiveness, benchmarking, development strategy, industrial policy

Clusters and Knowledge Local Buzz, Global Pipelines and the Process of Knowledge Creation

The paper is concerned with spatial clustering of economic activity and its relation to the spatiality of knowledge creation in various sorts of interactive learning processes. It questions the merit of the prevailing explanatory model where the realm of tacit knowledge transfer is confined to local milieus whereas codified knowledge may roam the globe almost frictionless. When doing so the paper highlights the conditions under which both tacit and codified knowledge can be exchanged locally and globally. A distinction is made between, on the one hand, the learning processes taking place among actors embedded in a community by just being there - dubbed buzz - and, on the other, the knowledge attained by investing in building channels of communication - called pipelines - to selected providers located outside the local milieu. It is argued, that the co-existence of high levels of buzz and many pipelines may provide firms located in outward looking and lively clusters with a string of particular advantages not available to outsiders. Finally, some prescriptive elements, stemming from the argument, are identified.knowledge creation, clusters, buzz, pipelines, absorptive capacity

Standards as a driving force that influences emerging technological trajectories in the converging world of the Internet and things: An investigation of the M2M/IoT patent network

While standards are said to create windows of opportunity in facilitation of technological convergence, it is not clear how they affect technological trajectories and strategic choices of firms in the face of convergence and in the process of catch-up. There is little research on the relationship between standards and technological trajectories, particularly in the age of convergence. This paper investigates how standards shape the emerging M2M/IoT technological trajectory and influence convergence in terms of technological importance and diversity. We, firstly, found that standards are a driving force of technological convergence. The second finding is that 3GPP standards assume a crucial role in setting the boundary conditions of the M2M/IoT technological systems. Third, we identified strategic groups and strategic patents that centered around the M2M/IoT trajectory. Forth, standards serve as an important factor in the process of creating a new path for catch-up firms (e.g. Huawei). These findings make contributions to innovation and standards studies by empirically examining the relationship between technological trajectories and standards. Furthermore, they clearly cast light on ongoing cooperation and competition along the M2M/IoT trajectory, and offer practical implications for catch-up strategies

Are Chinese firms innovative or imitative?

In recent time, many Chinese firms have not only operated quite successfully at their home front, competing with those giant multinational companies inside China, they are also moving offshore. The short internationalisation process of Chinese firms looks both sudden and unexpected, causing many to wonder the success factors for Chinese firms. A dynamic innovation that combines strategic, organisational, cost as well as technological change was believed to have contributed to the fast growing Chinese firms in the global stage. This paper reviews the literature related to these areas of innovation. It also discusses reasons for firms to innovate or imitate, using institutional perspective and resource-based view (RBV). Intertwined with these discuss ion, empirical studies of innovative performance among Chinese firms are also analysed. The results show that in fact most Chinese firms still follow an imitative strategy, but there is a clear evidence of strategic cost innovation widely practiced among Chinese firms.<br /

Learning disabilities and behavior disabilities as the relate to the black youth in the educational setting

The implication of a probable link between the Black juvenile delinquent and learning disabilities has been suggested by the researcher. In addition to the correlation between juvenile delinquency among Blacks and learning disabilities, a third dimension has also been directly correlated. The third dimension is the schools\u27 failure to adequately teach the Black youth effectively

THE OTHERS: the role of individual personality, cultural acculturation, and perceived value on towards firm’s social media and acculturation orientation

This paper systematically examines (i) how individual personality can influence on cultural acculturation which can impact on the higher level of perceived value in LGBTs, and (ii) how the higher level of perceived value towards social media can result in being more satisfied, (iii) consequently having a better working life at workplace and performance proficiency. The generated framework was validated through a survey from multinational corporations in multi-industries such as higher education (with more than two campuses around the world), global fashion, global retailing, tourism, hospitality, food, and electronics and information technology. Key results, implications for managers and researchers are highlighted
