Cloud services are widely used across the globe to store and analyze Big Data. These days it seems the news is full of stories about security breaches to these services, resulting in the exposure of huge amounts of private data. This paper studies the current security threats to Cloud Services, Big Data, and Hadoop. The paper analyzes a newly proposed Big Data security system based on the EnCoRe system...
Agile Software Development have become very important over the years for organizations of the modern world, however, software development itself is a very complex process. There are so many factors that affect project success or failure. This paper is a systematic review on the critical success factors of agile software development projects. We classified fourteen critical factors into three categories...
A social media message that is forwarded (e.g., Retweeted in Twitter) by many users may diffuse widely. Such a 'viral' message may have a major impact in the real world. If the content maligns a company, the company must respond as quickly as possible to defend its brand image. Timely knowledge about what kinds of information are diffusing in social media is thus quite important. We have developed...
Implementing sustainability practices has become a requirement to be able to operate in several markets since the legal requirements are increasing and society (as well as customers) values sustainability behaviors more.
Data fusion is a major task in data management. Frequently, different sources store data about the same real-world entities, however with conflicts in the values of their features. Data fusion aims at solving those conflicts in order to obtain a unique global view over those sources. Some solutions to the problem have been proposed in the database literature, yet they have a number of limitations...
Intelligence analysts are faced with a complex information fusion problem that is characterised by the volume, velocity, variety and veracity of the observed data and information. That is, there are large quantities of data and information (volume) arriving at a high rate (velocity) which are, in general, highly heterogeneous (variety) and of inconsistent fidelity (veracity). Making sound decisions...
Software quality assessments are critical in organizations where the software has been produced by external vendors, or when the development and maintenance of a software product has been outsourced to external parties. These assessments are typically challenging because is not always possible to access the original developers (or sometimes is not even allowed), and in rare cases suppliers keep an...
Todays changing and competitive labor markets present a huge challenge for students in finding a suitable internship position or job. The paper presents a developed working prototype of an online module, which serves as a career center in connecting students with academic institutions and companies in an effort to find and manage internship positions and jobs. The paper presents an overview of current...
Security related monitoring in high speed backbone networks is still a challenging task, since the amounts of data to process increases continuously. Thus, new approaches need to be investigated to detect and handle attacks in high-speed environments to protect the underlying access lines. Therefore, we introduce a new approach for redirecting suspicious traffic taking advantage of properties of OpenFlow...
Counting of passengers in public transport system is a very significant task which must be performed for sustainable city planning. In different countries and cities this task performed very differently, or not performed at all, as well as there are no clearly defined international standards for public transport passenger flow analysis, and as a result, for system sustainable development. There are...
Mankind has always pursued knowledge. Over the philosophy questions by Paul Gauguin (“where do we come from, what are we, where are we going”), the science may answer these questions. In every scientific field, empirical and theoretical researches are making to describe natural processes, to better understand the universe. The questions are modified by the scientists: are these two variables correlated,...
In the past (classical supply chain) the supply of goods generally flow starts from factory or producer, then producer sent to a storage area called the warehouse. When finished goods are collected, the goods from storage area or warehouse (WH) is distributed to the distribution center (DC). Then after the goods were placed in the Distribution center, then the goods are shipped to the retailer (retailer)...
Companies that develop complex systems often do so in the form of product lines, where each product variant can be configured to a certain degree to fit a customer's specific requirements. Features cannot be combined arbitrarily in a product line. The knowledge which features require or exclude each other is represented in form of variability models. Unfortunately, in practice, such variability models...
In this paper we describe a new approach to creating rich, dynamic and customized maps for business or leisure activities, and demonstrate how the approach can be implemented through a prototype system. The approach is aimed at changing the way we map the world by providing a meaningful and personalized context that is augmented with the semantic web, social media integration and sentiment analysis...
This paper is to disclose NPEs' patent portfolios internationally. The operation of NPEs has aroused impacts on society, and its patents have been considered as valuable patents, which are more valuable than ITC patents and litigated patents. The value of NPE patents is not occasionally. Hence, this paper uses application & publication of nations, and NPE patents applied under PCT procedures,...
In the strategic management field, the ecosystem concept is increasing significance. This paper provides an overview of 90 previous studies on the ecosystem concept published in leading academic journals in strategic management field and clarifies the four major research streams. The first perspective is the industrial ecosystem perspective, which is based on the concept of industrial ecology. The...
Bertossi et al. proposed a data-cleaning technique based on matching dependences and matching functions, which is, in practice, intractable for some cases during the application of matching dependences in random orders. Moreover, the result of the application of a single matching dependence on a dirty database instance is a set of clean instances depending on the number of dirty tuples, which results...
The developing of Estonian eGovernment components started approximately 15 years ago. In this article, we discuss our experience how the main components of Estonian eGovernment like public key infrastructure, data exchange layer and governmental portal have developed and changed within this period. Estonian ID-card is the best representative of our public key infrastructure technology. The project...
Although more knowledge might be better for a firm, not all technological knowledge can create and realize economic value. Firms must commercialize their knowledge or resources. Based on panel data of Bio-Pharm industry from 1987 to 2008 by combining USPTO Patent Assignment, NEBR, SDC, and Compustat database, 96 US-based technology public firms comprised the empirical base for testing the moderating...
This paper introduces two fuzzy fingerprint based text classification techniques that were successfully applied to automatically label companies from CrunchBase, based purely on their unstructured textual description. This is a real and very challenging problem due to the large set of possible labels (more than 40) and also to the fact that the textual descriptions do not have to abide by any criteria...
