    Presence on the Web and the realization of webometric indicators are one of the most important indicators of reflecting the international presence of universities. This study evaluates the content and technical characteristics that influence webometric rankings on Golestan University of Medical Sciences websites. This research is a descriptive practical survey that describes the status of the website based on the content and technical features that influence the promotion of webometric rankings. A total of 53 Golestan University of Medical Sciences websites were included, consisted of 7 college websites, 8 Deputies websites, and 16 websites for hospitals and 22 websites for research centers. Data were collected using checklist. Result shows that 49.46 percent of the expected indicators were met by the units. Colleges with the overall average of 57.64 percent had the highest compliance and the hospitals with 36.72 percent had the lowest compliance with the webometric indexes. The results show that 54.72 percent of the Deputies and 47.73 percent of the research centers have met the indicators. According to the findings, notice to the indicators that less-considered, is necessary for webometric managers and researchers. Also, given that Golestan University of Medical Sciences is the weakest in the Impact Index, considering the number of backlinks identified by search engines is one of the priorities of web infrastructure enhancement programs

    Get PDF
    Overview This paper is a review of how information and insight can be drawn from open social media sources. It focuses on the specific research techniques that have emerged, the capabilities they provide, the possible insights they offer, and the ethical and legal questions they raise. These techniques are considered relevant and valuable in so far as they can help to maintain public safety by preventing terrorism, preparing for it, protecting the public from it and pursuing its perpetrators. The report also considers how far this can be achieved against the backdrop of radically changing technology and public attitudes towards surveillance. This is an updated version of a 2013 report paper on the same subject, State of the Art. Since 2013, there have been significant changes in social media, how it is used by terrorist groups, and the methods being developed to make sense of it.  The paper is structured as follows: Part 1 is an overview of social media use, focused on how it is used by groups of interest to those involved in counter-terrorism. This includes new sections on trends of social media platforms; and a new section on Islamic State (IS). Part 2 provides an introduction to the key approaches of social media intelligence (henceforth ‘SOCMINT’) for counter-terrorism. Part 3 sets out a series of SOCMINT techniques. For each technique a series of capabilities and insights are considered, the validity and reliability of the method is considered, and how they might be applied to counter-terrorism work explored. Part 4 outlines a number of important legal, ethical and practical considerations when undertaking SOCMINT work

    Untangling the Web: A Guide To Internet Research

    [Excerpt] Untangling the Web for 2007 is the twelfth edition of a book that started as a small handout. After more than a decade of researching, reading about, using, and trying to understand the Internet, I have come to accept that it is indeed a Sisyphean task. Sometimes I feel that all I can do is to push the rock up to the top of that virtual hill, then stand back and watch as it rolls down again. The Internet—in all its glory of information and misinformation—is for all practical purposes limitless, which of course means we can never know it all, see it all, understand it all, or even imagine all it is and will be. The more we know about the Internet, the more acute is our awareness of what we do not know. The Internet emphasizes the depth of our ignorance because our knowledge can only be finite, while our ignorance must necessarily be infinite. My hope is that Untangling the Web will add to our knowledge of the Internet and the world while recognizing that the rock will always roll back down the hill at the end of the day

    Detecting, Modeling, and Predicting User Temporal Intention

    The content of social media has grown exponentially in the recent years and its role has evolved from narrating life events to actually shaping them. Unfortunately, content posted and shared in social networks is vulnerable and prone to loss or change, rendering the context associated with it (a tweet, post, status, or others) meaningless. There is an inherent value in maintaining the consistency of such social records as in some cases they take over the task of being the first draft of history as collections of these social posts narrate the pulse of the street during historic events, protest, riots, elections, war, disasters, and others as shown in this work. The user sharing the resource has an implicit temporal intent: either the state of the resource at the time of sharing, or the current state of the resource at the time of the reader \clicking . In this research, we propose a model to detect and predict the user\u27s temporal intention of the author upon sharing content in the social network and of the reader upon resolving this content. To build this model, we first examine the three aspects of the problem: the resource, time, and the user. For the resource we start by analyzing the content on the live web and its persistence. We noticed that a portion of the resources shared in social media disappear, and with further analysis we unraveled a relationship between this disappearance and time. We lose around 11% of the resources after one year of sharing and a steady 7% every following year. With this, we turn to the public archives and our analysis reveals that not all posted resources are archived and even they were an average 8% per year disappears from the archives and in some cases the archived content is heavily damaged. These observations prove that in regards to archives resources are not well-enough populated to consistently and reliably reconstruct the missing resource as it existed at the time of sharing. To analyze the concept of time we devised several experiments to estimate the creation date of the shared resources. We developed Carbon Date, a tool which successfully estimated the correct creation dates for 76% of the test sets. Since the resources\u27 creation we wanted to measure if and how they change with time. We conducted a longitudinal study on a data set of very recently-published tweet-resource pairs and recording observations hourly. We found that after just one hour, ~4% of the resources have changed by ≄30% while after a day the change rate slowed to be ~12% of the resources changed by ≄40%. In regards to the third and final component of the problem we conducted user behavioral analysis experiments and built a data set of 1,124 instances manually assigned by test subjects. Temporal intention proved to be a difficult concept for average users to understand. We developed our Temporal Intention Relevancy Model (TIRM) to transform the highly subjective temporal intention problem into the more easily understood idea of relevancy between a tweet and the resource it links to, and change of the resource through time. On our collected data set TIRM produced a significant 90.27% success rate. Furthermore, we extended TIRM and used it to build a time-based model to predict temporal intention change or steadiness at the time of posting with 77% accuracy. We built a service API around this model to provide predictions and a few prototypes. Future tools could implement TIRM to assist users in pushing copies of shared resources into public web archives to ensure the integrity of the historical record. Additional tools could be used to assist the mining of the existing social media corpus by derefrencing the intended version of the shared resource based on the intention strength and the time between the tweeting and mining

    Este estudo examina o uso do marketing de conteĂșdo digital por parte de hotĂ©is portugueses nos seus blogues. SĂŁo analisadas boas prĂĄticas que a literatura aponta que devem ser utilizadas em blogues para que estes sejam bem-sucedidos na relação com o utilizador. Estas boas prĂĄticas sustentam-se no uso de aspetos especĂ­ficos que beneficiam a gestĂŁo do blogue. O estudo oferece uma visĂŁo do nĂ­vel da adoção dessas boas prĂĄticas/aspetos por parte de 22 hotĂ©is analisados. O estudo Ă© motivado pela escassez de informação existente sobre hotelaria portuguesa e o uso que esta faz do marketing de conteĂșdo digital nos seus blogues. Foram encontrados estudos que evidenciam a importĂąncia do marketing de conteĂșdo digital e a sua estreita ligação aos blogues noutras ĂĄreas, mas verifica-se uma lacuna na investigação deste tĂłpico aplicado Ă  hotelaria. Desta forma, este estudo centra-se em analisar como o marketing de conteĂșdo digital Ă© utilizado nos blogues de hotĂ©is portugueses. Os dados foram recolhidos atravĂ©s de um website gerido pelo Turismo de Portugal, no qual foi possĂ­vel extrair-se uma lista de hotĂ©is de 4 e 5 estrelas. Desta forma, foram identificados 198 websites de hotĂ©is de 5 estrelas e 795 websites de hotĂ©is de 4 estrelas, de forma a registar todos os hotĂ©is que incorporavam blogues nos seus sites. ApĂłs esta fase preliminar, foi reunida uma amostra de 22 hotĂ©is com blogues, nos quais se analisou seis dos seus mais recentes artigos/posts. Para o efeito, foi realizada uma anĂĄlise de conteĂșdo dos mesmos, com uma aplicação quantitativa. Foram reunidas e analisadas 11 categorias principais e em alguns casos subcategorias, nomeadamente 1) “conteĂșdo educativo” (webinars, infogrĂĄficos e e-books), 2) “credibilidade” (nome do autor), 3) “utilidade” (viagens/fĂ©rias, dicas, lugares a visitar, relacionado ao negĂłcio), 4) “relevĂąncia” (categorias), 5) “consistĂȘncia”, 6) “atual”, 7) “cativante” (podcasts, vĂ­deos, ĂĄudio, animaçÔes e imagens), 8) “comentĂĄrios”, 9) “dimensĂŁo do texto”, 10) “botĂ”es de partilha” e 11) “artigos sugeridos”. A anĂĄlise permitiu verificar que existe uma escassez de hotĂ©is de 4 e 5 estrelas em Portugal com blogue no seu website, de acordo com os critĂ©rios usados no presente estudo. AlĂ©m disso, algumas das categorias analisadas, como “conteĂșdo educacional” e suas subcategorias, nomeadamente webinars, infogrĂĄficos e e-books, nĂŁo estĂŁo a ser utilizados pelos blogues dos hotĂ©is analisados. Ademais, na categoria analisada onde se tenta perceber se o conteĂșdo Ă© “cativante” (engaging), relativamente Ă s suas subcategorias, nomeadamente podcasts, vĂ­deos, ĂĄudio, animaçÔes e imagens, concluiu-se que esta Ășltima subcategoria (imagens) Ă© a mais adotada pela grande maioria dos hotĂ©is nos posts dos seus blogues. Verificou-se que dos 22 hotĂ©is, 21 (95%) utilizam imagens nos seus blogues. O uso das outras subcategorias Ă© quase residual. Embora a literatura aponte como importante exibir o nome do autor do post/artigo no final do mesmo como forma de dar mais credibilidade, apenas 4 blogues (18%) incluem esta caracterĂ­stica. Relativamente Ă  atenção dada ao grau de “utilidade” (value) dos posts para os utilizadores, verificou-se que apenas 2 dos blogues analisados (9%) fazem melhor uso desta caracterĂ­stica de forma consistente. Cerca de 41% recorrem a esta boa prĂĄtica mas nĂŁo de forma consistente. Com respeito Ă  caracterĂ­stica que indica que o blogue deve dar a possibilidade ao utilizador de escolher entre diferentes categorias (relevĂąncia), verificou-se que apenas 7 hotĂ©is (32%) fazem uso desta opção. Verificou-se tambĂ©m que Ă© importante que os blogues façam uma partilha regular de posts/artigos. Nesta categoria foi verificada a sua consistĂȘncia ao longo do tempo. Os resultados apontam que 7 blogues (32%) partilham posts de forma consistente. Analisou-se se os blogues partilham posts que sejam atuais e que estejam ligados a eventos recentes. Verificou-se que 16 blogues (73%) partilharam posts que aplicam esta boa prĂĄtica de marketing de conteĂșdo digital. Relativamente Ă  caracterĂ­stica que se refere Ă  possibilidade de os utilizadores deixarem comentĂĄrios nos posts, constatou-se que apenas 2 blogues (9%) permitem que o utilizador deixe comentĂĄrios, o que nĂŁo Ă© consistente com a ideia de interatividade esperada ao nĂ­vel do marketing de conteĂșdos digitais aplicado aos blogues. Com respeito Ă  dimensĂŁo do texto dos posts, a literatura enfatiza a recomendação de que estes devem ter um mĂ­nimo de extensĂŁo de 500 palavras. Nesta caracterĂ­stica, “dimensĂŁo do texto”, verificou-se que apenas 2 blogues (9%) sĂŁo consistentes em todos os posts analisados. Embora alguns blogues partilhem artigos que respeitam este nĂșmero de palavras, estes nĂŁo sĂŁo consistentes em todos os posts analisados Analisou-se se os blogues dos hotĂ©is incorporavam um botĂŁo (share button) diretamente nos posts que permitisse a que os utilizadores pudessem partilhar o post nas suas redes sociais. Aqui analisaram-se 3 redes sociais diferentes, nomeadamente Facebook, LinkedIn e Twitter, assim como a possibilidade de partilha via email. Constatou-se que 9 blogues (41%) permitem partilhar artigos diretamente no Facebook, seguido pelo Twitter, com 8 blogs (36%), LinkedIn com 6 blogs (27%) e e-mail com 5 blogs (23%). Os resultados indicam tambĂ©m se os blogues fazem a sugestĂŁo de leitura de outros posts relacionado no prĂłprio post que o utilizador leia. Desta forma, observou-se que 16 blogues (73%) aplicam esta boa prĂĄtica. Este estudo revelou que as boas prĂĄticas analisadas sĂŁo importantes para que os hotĂ©is possam otimizar os seus blogues a nĂ­vel da estratĂ©gia de comunicação digital, por conseguinte, tornar a sua relação com os utilizadores mais prĂłxima. Do que foi analisado, constata-se que nenhum blogue reĂșne todas as categorias e subcategorias examinadas. No entanto, existem pelo menos 2 hotĂ©is que sobressaem em comparação com os demais, como aplicando o maior nĂșmero de boas prĂĄticas de marketing de conteĂșdos digitais em blogues. De uma forma geral, a maioria dos blogues nĂŁo segue as prĂĄticas recomendadas na literatura de forma consistente, nĂŁo estando, dessa forma, a usufruir de todos os benefĂ­cios de uma estratĂ©gia de comunicação digital por via desta ferramenta. Este estudo contribui para a literatura de marketing de conteĂșdo digital com aplicação em blogues de hotĂ©is. Preenche uma lacuna existente ao nĂ­vel do conhecimento, investigando de forma exaustiva o uso do marketing de conteĂșdo digital no uso de blogues que geridos por hotĂ©is de 4 e 5 estrelas em Portugal. A metodologia usada pode ser usada no futuro no Ăąmbito de outras tipologias de alojamento. AlĂ©m disso, esta investigação enfatiza para a importĂąncia do uso de blogues de forma consistente e estruturada. RecomendaçÔes de marketing sĂŁo oferecidas com o foco na gestĂŁo de marketing de hotĂ©is com recurso a blogues.The main objective of this study is to examine if companies such as hotels follow the best practices recommended in digital content marketing (DCM) literature in relation to their blogs. More specifically, it is intended to analyze if the content shared by Portuguese hotels on their blogs adhere to the elements that literature highlights as important for developing engagement with the audience. In so doing, 22 hotel blogs were compared by highlighting the ones that follow the best practices and the reverse situation. This study is motivated by the scarcity of existing research on Portuguese hotels and their use of digital content marketing on their blogs. A content analysis approach using 11 categories (characteristics identified in literature) revealed that the good practices analyzed are important so that hotels optimize their blogs and, therefore, improve their relationship with users. The findings show that no blog brings together all the good practices examined. Of all the hotels studied, 2 hotel blogs stand out in comparison to the others by implementing the characteristics that literature points out as relevant in a good digital communication strategy via blogs. In general, the majority of blogs do not follow the practices recommended in literature in a consistent way, and therefore are not optimizing their blogs as a communication tool. This study contributes significantly to the digital content marketing literature with application on hotel blogs. It fills an existing research gap, by examining the use of digital content marketing via blogs in a hospitality context, with a focus on 4 and 5 star hotels. As a result, this research offers marketing recommendations addressed to hotels, considering the use of DCM with regards to blogs

    A Study of Information Fragment Association in Information Management and Retrieval Applications

    Get PDF
    As we strive to identify useful information sifting through the vast number of resources available to us, we often find that the desired information is residing in a small section within a larger body of content which does not necessarily contain similar information. This can make this Information Fragment difficult to find. A Web search engine may not provide a good ranking to a page of unrelated content if it contains only a very small yet invaluable piece of relevant information. This means that our processes often fail to bring together related Information Fragments. We can easily conceive of two Information Fragments which according to a scholar bear a strong association with each other, yet contain no common keywords enabling them to be collocated by a keyword search.This dissertation attempts to address this issue by determining the benefits of enhancing information management and retrieval applications by providing users with the capability of establishing and storing associations between Information Fragments. It estimates the extent to which the efficiency and quality of information retrieval can be improved if users are allowed to capture mental associations they form while reading Information Fragments and share these associations with others using a functional registry-based design. In order to test these benefits three subject groups were recruited and assigned tasks involving Information Fragments. The first two tasks compared the performance and usability of a mainstream social bookmarking tool with a tool enhanced with Information Fragment Association capabilities. The tests demonstrated that the use of Information Fragment Association offers significant advantages both in the efficiency of retrieval and user satisfaction. Analysis of the results of the third task demonstrated that a mainstream Web search engine performed poorly in collocating interrelated fragments when a query designed to retrieve the one of these fragments was submitted. The fourth task demonstrated that Information Fragment Association improves the precision and recall of searches performed on Information Fragment datasets.The results of this study indicate that mainstream information management and retrieval applications provide inadequate support for Information Fragment retrieval and that their enhancement with Information Fragment Association capabilities would be beneficial

    Constructing an online serviceScape for the funeral industry

    An online servicescape serves as a moderator for excellence in Customer Relationship Management (CRM). The study approached the online servicescape from the perspective of the funeral industry. Nowhere is the relevance of an online servicescape more apparent than in an industry which is firstly, unsought, and secondly, perceived as dismal. During the process of arranging a funeral, the customer is experiencing an unusual purchase situation as it is a purchase that cannot be avoided. The possibility also exists that the customer most likely did not seek information about a funeral home prior to the demise of a loved one. A third contributing factor is the emotional state of the customer which will, in a time of bereavement, have a strong impact on the rational decision-making process. Considering these conditions, the study approached the online servicescape based on three elements, namely Search Engine Optimisation, perceived value, and perceived usefulness of the online servicescape. These elements contribute to trust in the funeral home’s online offerings, which could influence the purchase outcomes significantly. The aim of the study was to construct a functional servicescape for an unsought business such as a funeral home, hence contributing significantly to the CRM body of knowledge as it was determined that this has not been explored before from an academic perspective. A quantitative, exploratory methodology was implemented. The exploration is depended on Bitner's (1992a:60) seminal model of servicescapes, Harris and Goode's (2010:230-243) model for online servicescapes, and the key constructs of Simon's (1996:141-142) Design Theory to provide a methodological basis with which to construct the key elements for a funeral industry based online servicescape. The data collection process followed a twostep process. A content analysis was conducted on existing websites from five English speaking countries, followed by a survey that largely reflected the content analysis variables to gain customer insights. The data was analysed using a descriptive analysis process. v It was determined that customers would trust a functional servicescape, which will most probably lead to a purchase situation. However, customers also indicated the opposite if they detect anything on the website that might lead to distrust. It was therefore concluded that it is imperative for a funeral home to ensure that their online servicescape meets the functional needs of customers in order ensure trust and purchase intention.Thesis (PhD) -- Faculty of Business and Economic science, 202
