One of the crucial trends in business is to offer one-to-one personalized services. In this context, companies try to build customer relationship management systems based on the customer social relations and behavioral patterns. The key issue is predicting to which products or services a particular customer is likely to respond. Additionally, ident...
Article
Social exchange theory proposes that social behavior is the result of an exchange process. The purpose of this exchange is to maximize benefits and minimize costs. Online social networks seem to be an ideal platform for social exchange because they provide an opportunity to keep social relations with a relatively low cost compared to offline relati...

On-line social network sites provide an excellent platform for studying social influence among on-line friends. One of the crucial factors in analyzing social influence is conformity. Conformity can be defined as the act of matching attitudes, beliefs, and behaviors to group norms. This paper analyzed the level of conformity of 175 Facebook users,...

Conference Paper
When using mobile phones, credit cards, electronic mail, browsing social networks etc., contemporary consumers leave behind thousands of digital footprints. Each footprint reflects actual actions that we take in given place and time. The analysis of thousands of such footprints conducted among large groups of people allows us to examine human behav...
Article
The practice of strategy decision making proves that when the management board is strongly limited in its capacity to take rational actions, specifically in the context of great decision complexity and uncertainty, it is considered good practice to refer to experience through reasoning by analogy. In this paper, we would like to concentrate on supp...

Promotional campaigns implemented in web-based social networks are growing in popularity due to an increasing number of users in virtual communities. A study concerning an advertising campaign in a popular social network is presented in this article. Identification of the profile of a group of people responding positively to a banner ad allows for...
Article
Wojciech Woziwodzki, co-founder, president & CEO of Tequila Mobile SA, a mobile gamers developer, publisher and service provider, had to make some important strategic decisions. Tequila Mobile SA had already decided to shift to a new "free2play" revenue model but needed to decide whether to focus on building its business in markets where penetratio...
Chapter
Contemporary companies try to build customer relationship management systems based on the customer social relations and behavioral patterns. This is in correspondence with the current trend in marketing that is to move from broadcast marketing operation to a one-to-one marketing. The key issue in this activity is predicting to which products or ser...
Conference Paper
Business usage of online social networks is a natural result of their intense development in last years. The information about members of a given community can be treated as a basis of correct identification of their needs and as a result adjusting personalized marketing messages. In this study, we will discuss the classification and regression tre...
Article
Full-text available
Marketing in web based social networks (virtual communities) became one of the crucial topics in contemporary business. There are three reasons why this area of marketing usage is interesting. Firstly, there are more and more users of social media in the Internet. Secondly, access to behavioral data of potential clients permits acquiring knowledge...

Conference Paper
Making strategic decisions in an enterprise is one of the most difficult problems of management. It is a result of unstructured character of such decisions which are made in conditions of high uncertainty. This issue is particularly important in case of Small and Medium Enterprises (SME), where Chief Executive Officers (CEO) are lacking support in...
Conference Paper
Social networks have generated great expectations connected with their potential business value. The purpose of our research is to present that even a rudimentary application of data mining techniques can bring statistically significant improvement in marketing response accuracy throughout the virtual community. In our test the C&RT (classification...

Article
This paper describes in full detail an analysis of two expert system shells: Level 5 Object and Kappa PC. The major components of these tools (knowledge representation, inference and control, developer interface, user interface and explanation facility, interface to external data sources, support and documentation) were studied and tested by means...
Chapter
Case-Based Reasoning (CBR) paradigm is very close to the designer behavior during the conceptual design, and seems to be a fruitable computer aided-design approach if a library of design cases is available. The goal of this paper is to presents the general framework of a case-based retrieval system: REPRO, that supports chemical process design. The...
Conference Paper
Apart from the classification accuracy the solution time is one of the most critical factors in real world applications, especially in real-time intelligent systems. Maximum time t is often known and it must not be exceeded during solving a new case. Knowing parameter t in Case-Based Reasoning systems, the maximum size of the case base can be deter...
Article
this paper is to present the similarity measure for aggregation taxonomies. The computational complexity of the proposed measure is linear due to a domainoriented matching heuristic. A detailed description of the similarity measure and evaluation on a real design problem is given. The experimental results and the expert evaluation show the usefulne...

One of the most important challenges in developing problem solving methods is to combine and synergistically utilize general and specific knowledge. This paper presents one possible way of performing this integration that might be generally described as follows: "To solve a problem, first try to use the conventional rule- based approach. If it does...

ion strategy during local components comparison. The local-root of the component x will be denoted: local-root(x). . function defines the role (the task) of a given component in a flowsheet aggregation. The function of the component x will be denoted: function(x). . quantity defines how many identical components perform the function specified in th...

. The recent progress in Case- Based Reasoning has shown that one of the most important challenges in developing future AI methods will be to combine and synergistically utilize general and case-based knowledge. In this paper a very rudimentary kind of integration for the classification task, based on simple heuristics, is sketched: "To solve a pro...
Conference Paper
Case-based reasoning (CBR) can be used as a form of "caching" solved problems to speedup later problem solving. Using "cached" cases brings additional costs with it due to retrieval time, case adaptation time and also storage space. Simply storing all cases will result in a situation in which retrieving and trying to adapt old cases will take more...
Article
Case-Based Reasoning lets computer-aided design systems use prior experience to solve new problems. This approach seems to be very fruitful for supporting conceptual design activities if a library of design cases is available. The main goal of this paper is to present the general framework of a case-based design system for supporting a designer thr...
