    This paper reviews the value of social networking and the impact it can have on small and large businesses. The paper also reviews the Social Networking Business Plan and the power of recommender networks. Examples are given of inbound and outbound marketing techniques. Social Networking is an integral part of inbound marketing. A synopsis of the evolving demographic of social networkers is presented to add clarity and show potential for social networking websites and tools.social networking, business, Facebook, The Social Network Business Plan, Social Networking Strategy, social networking demographics, inbound marketing, outbound marketing, advertising in the 21st century

    A Logical Framework for Identifying and Explaining Unexpected News

    Get PDF
    The number of news reports published online is too large for any person to read all of them. Not all of these reports are equally interesting. Automating the identification and evaluation of interest in news is therefore a valuable goal. This paper presents a framework that permits the identification of interesting news by means of violated expectations. Facts derived from news reports, expectations and related background knowledge can be used to (i) justify the decision to rate news as interesting, (ii) explain why the information in the report is unexpected and, (iii) explain the context in which the report appears. Explanations supported by this framework are general purpose explanations based on the data in the system. The explanations are natural language renditions of first order logic facts and rules

    Cultural heritage appraisal by visitors to global cities: the use of social media and urban analytics in urban buzz research

    An attractive cultural heritage is an important magnet for visitors to many cities nowadays. The present paper aims to trace the constituents of the destination attractiveness of 40 global cities from the perspective of historical-cultural amenities, based on a merger of extensive systematic databases on these cities. The concept of cultural heritage buzz is introduced to highlight: (i) the importance of a varied collection of urban cultural amenities; (ii) the influence of urban cultural magnetism on foreign visitors, residents and artists; and (iii) the appreciation for a large set of local historical-cultural amenities by travelers collected from a systematic big data set (emerging from the global TripAdvisor platform). A multivariate and econometric analysis is undertaken to validate and test the quantitative picture of the above conceptual framework, with a view to assess the significance of historical-cultural assets and socio-cultural diversity in large urban agglomerations in the world as attraction factors for visitors. The results confirm our proposition on the significance of urban cultural heritage as a gravity factor for destination choices in international tourism in relation to a high appreciation for historical-cultural amenities.info:eu-repo/semantics/publishedVersio

    ConCall: An information service for researchers based on EdInfo

    Get PDF
    In this paper, we present new types of web information services, where users and information brokers collaborate in creating a user-adaptive information service. Such services impose a novel task on information brokers: they become responsible for maintaining the inference strategies used in user modeling. In return, information brokers obtain more accurate information about user needs, since the adaptivity ensures that user profiles are kept up to date and consistent with what users actually prefer, not only what they say that they prefer. We illustrate the approach by an example application, in which conference calls are collected and distributed to interested readers

    Enhancing Recommender System Performance by Histogram Equalization

    Full text link
    Recommender system has been researched for decades with millions of different versions of algorithms created in the industry. In spite of the huge amount of work spent on the field, there are many basic questions to be answered in the field. The most fundamental question to be answered is the accuracy problem, and in recent years, fairness becomes the new buzz word for researchers. In this paper, we borrow an idea from image processing, namely, histogram equalization. As a preprocessing step to recommender system algorithms, histogram equalization could enhance both the accuracy and fairness metrics of the recommender system algorithms. In the experiment section, we prove that our new approach could improve vanilla algorithms by a large margin in accuracy metric and stay competitive on fairness metrics

    Movie Recommender System Using Decision Tree Method

    Get PDF
    In this modern era, many things that can be done online, one of which is watching movies. When the number of movies increases, people often find it difficult to decide which movie to watch next. To solve this problem, a useful recommendation system was developed to find movies that one might like based on movies that have been watched before. This research develops a movie recommendation system using Collaborative Filtering (CF) with the Decision Tree algorithm. In this study, the data used were movie data and ratings obtained from the grouplens.org website. Then the movielens dataset is filtered and only saves movies with a rating of more than 50 that are used in the recommendation system. In this study, Mean Absolute Error (MAE) is used as a method to assess the accuracy of the movie recommendation system. Based on the research that has been done, Decision Tree gets better results with an MAE value of 0,942 compared to Collaborative Filtering with an MAE value of 1,242

    Analysis of Probabilistic News Recommender Systems

    Get PDF
    The focus of this research is the N “most popular” (Top-N) news recommender systems (NRS), widely used by media sites (e.g. New York Times, BBC, Wall Street Journal all prominently use this). This common recommendation process is known to have major limitations in terms of creating artificial amplification in the counts of recommended articles and that it is easily susceptible to manipulation. To address these issues, probabilistic NRS has been introduced. One drawback of the probabilistic recommendations is that it potentially chooses articles to recommend that might not be in the current “best” list. However, the probabilistic selection of news articles is highly robust towards common manipulation strategies. This paper compares the two variants of NRS (Top-N and probabilistic) based on (1) accuracy loss (2) distortion in counts of articles due to NRS and (3) comparison of probabilistic NRS with an adapted influence limiter heuristic

    Toward a New Framework of Recommender Memory Based System for MOOCs

    Get PDF
    MOOCs is the new wave of remote learning that has revolutionized it since its apparition, offering the possibility to teach a very big group of student, at the same time, in the same course, within all disciplines and without even gathering them in the same geographic location, or at the same time; Allowing the sharing of all type of media and document and providing tools to assessing student performance. To benefit from all this advantages, big universities are investing in MOOCs platforms to valorize their approach, which makes MOOC available in a multitude of languages and variety of disciplines. Elite universities have open their doors to student around the world without requesting tuition or claiming a college degree, however even with the major effort reaching to maximize students visits and hooking visitors to the platform, using recommending systems propose content likely to please learners, the dropout rate still very high and the number of users completing a course remains very low compared to those who have quit. In this paper we propose an architecture aiming to maximize users visits by exploiting users big data and combining it with data available from social networks
