Atıf Klasiklerinin Etkisinin ve İlgililik Sıralamalarının Pennant Diyagramları ile Analizi

Citation indexes are important authority resources for measuring the contribution of scientists and scientific publications to literature. Many studies in information retrieval are based on research aiming to develop retrieval algorithms. These studies tend to receive citations from different fields because of the interdisciplinary nature of information retrieval. Therefore, it is important to analyze the so-called “citation classics” retrospectively to find out their impact on other fields. Yet, it is not easy to do this using citation indexes, especially for relatively old papers, as traditional citation analysis tends not to reveal the full impact of a work on other studies at its time and periods that follow. In order to see the big picture it is important to study the contribution of these studies on other disciplines as well. In this study the impact of Maron and Kuhns’ citation classic on “probabilistic retrieval” published in 1960 has been visualized using pennant diagrams that were developed on the basis of relevance theory, information retrieval and bibliometrics. We hypothesized that “The interdisciplinary relations that are unobservable with traditional citation analysis can be revealed using the pennant diagrams method”. In order to test the hypothesis works that cited Maron and Kuhns’ study between the years of 1960 and 2015 have been downloaded with their references (a total of 4,176 unique works) and graphics have been prepared by the macros written in MS Excel. Of 4,176 works, 90 were selected using convenience sampling techniques to create static and interactive pennant diagrams for further analysis. Another important output of this study is the relevance rankings. As an alternative to the relevance rankings based on the similarity of references already used in citation indexes, relevance rankings have been created using the pennant diagrams that took into account not only items that cited the core (seed) paper but also citations to the items that cited the core paper. Relevance rankings based on the similarity of references and that of pennant diagrams have been compared. Findings support the hypothesis in that pennant diagrams provide information as to which papers that the core paper on probabilistic model influenced or got influenced from, directly or indirectly. Relevance ranking based on pennant diagrams revealed the impact of the core paper on information retrieval field as well as on other disciplines. Furthermore, it identified the relations between these somewhat disconnected fields, between authors, works, and journals that cannot be readily identified using traditional citation analysis. Relevance rankings using pennant diagrams seem to have been more successful than the relevance rankings based on references similarity. This study is the first such study in Turkey that uses pennant diagrams for relevance rankings. The data used in graphs and relevance rankings are available through citation indexes (the frequencies of total citations and co-citations). Thus, alternative relevance rankings based on pennant diagrams can be offered to users. Pennant diagrams can help researchers track the relevant literature more easily as well as identify how a core work influences other works in a specific field or in other fields

Identifying Web search session patterns using cluster analysis: A comparison of three search environments

Information seeking models are important to design more efficient information retrieval systems. For this purpose, information retrieval systems transaction log studies were performed based on the Session, but there has never been a comparison whether different types of session groups are compatible with each other or not. In this study, three different types2 of Web-based information retrieval systemsare studied the search session models using clustering methods. Results have shown that searching behaviors are clustered into distinct groups by characteristic of sessions and revealed although being different groups, they show similarities. Session-based analysis is important for the understanding of user search behavior; this can help to system designers to develop systems to meet the needs of various user groups in a better way.Kullanıcıların daha etkin kullanabileceği erişim sistemleri tasarlamak için bilgi arama modellerinin incelenmesi önemlidir.

Paths of discovery: Comparing the search effectiveness of EBSCO Discovery Service, Summon, Google Scholar, and conventional library resources.

It is becoming hard for users to select significant sources among many others as number of scientific publications increase (Henning and Gunn, 2012). Search engines that are using cloud computing methods such as Google can list related documents successfully answering user requirements (Johnson, Levine and Smith, 2009). In order to meet users’ increasing demands, libraries started to use systems which enable users to access printed and electronic sources through a single interface. This study uses quantitative and qualitative methods to compare search effectiveness between Serial Solutions Summon, EBSCO Discovery Service (EDS) web discovery tools, Google Scholar (GS) and conventional library databases among users from Bucknell University and Illinois Wesleyan University.Bilimsel yayın sayısı arttıkça kullanıcılar için en ilgili ve dikkate değer kaynakları diğerleri arasında seçmek zorlaşmaktadır (Henning ve Gunn, 2012). Bulut hesaplama yöntemi kullanan Google gibi arama motorları kullanıcı gereksinimlerine hızla cevap vererek arama sonuçlarında ilgili belgeleri başarıyla sıralamaktadır (Johnson, Levine ve Smith, 2009). Kütüphaneler bu ortamda kullanıcıların giderek artan beklentilerini karşılamak için koleksiyonlarındaki basılı ve elektronik kaynaklara sadece bir arayüzden erişim imkânı sağlayan sistemler kullanmaktadır. Çalışmada hem nicel hem nitel yöntem kullanılarak Bucknell Üniversitesi (BÜ) ve Illinois Wesleyan Üniversitesi (IWÜ)’nden kullanıcıların Serial Solutions Summon, EBSCO Discovery Service (EDS) web keşif araçları ile Google Scholar (GS) ve geleneksel kütüphane veri tabanlarının arama etkinlikleri karşılaştırılmıştır

Open Access to Graduate Theses and Dissertations in Turkey

Lisansüstü tezler üniversitelerin en önemli araştırma çıktılarından birisidir. Fakat lisansüstü tezleri bulmak ve bu tezlere erişim sağlamak genellikle zordur. Son zamanlarda tezlerin tam metinlerine Internet aracılığıyla erişim sağlamak mümkün hale gelmiş olmasına karşın, erişimle ilgili sorunlar halen devam etmektedir. Bu araştırmada Türkiye’de lisansüstü tezlere açık erişim sorunu irdelenmektedir. Bu amaçla Yükseköğretim Kurulu Ulusal Tez Merkezi tez dermesinde bulunan tezlerin tam metin erişime açık olup olmadıkları incelenmiş, uygulanan bir anket aracılığıyla tezlerini geçici olarak erişime kapatmayı tercih eden tez yazarlarının konuyla ilgili görüşlerine başvurulmuştur. Lisansüstü tezlerin yaklaşık üçte biri tam metin erişime kapalıdır. Erişime kapalı olan tezlerin büyük bir çoğunluğu 2006 yılından önce yapılan ve erişime açmak için izin almak üzere yazarlarına ulaşılamayan tezlerdir. Tez yazarlarının büyük bir çoğunluğu (%94) teze dayanan yayın yapmak istedikleri, yaklaşık üçte ikisi (%63) tezlerinin kopyalanmasından korktukları için tezlerini geçici olarak erişime kapattıklarını belirtmişlerdir. Ancak tez yazarlarının çoğu (%81) genelde tezlerin tam metin erişime açılmasını desteklemektedirler. Bulgular lisansüstü tezlere açık erişim sorununun daha geniş bir bakış açısıyla ele alınması gerektiğini göstermektedir. Bulgular doğrultusunda lisansüstü tezlere erişimle ilgili çeşitli sorunlar tartışılmış ve bazı çözüm önerileri sunulmuştur.Graduate theses and dissertations are one of the most important research outputs of universities. Yet, it is often difficult to find and provide access to them. Although it is now possible to get access to full-texts of theses and dissertations through the Internet, access problems still persist. In this paper, we investigate the issues of open access to graduate theses and dissertations in Turkey. We first reviewed the collection of the Higher Education Council Theses Center to find out what percentage of theses is accessible full-text. We then, through a questionnaire survey, collected the views of the authors of theses who opted to restrict access to their theses temporarily. Access to about one third of theses is restricted. As it was difficult to reach the authors of older theses and get their consent to make their theses available online, most of the restricted theses belong to pre-2006 period. An overwhelming majority (94%) of the authors restricted access to their theses because they wanted to publish papers based on their theses while two thirds (63%) did so because they feared of their theses being plagiarized. Yet, 81% of them said they support open access to theses and dissertations in general. Findings suggest that the issue of open access to theses needs to be dealt with from a broader perspective. We discuss the various access issues on the basis of our findings and offer some suggestions to solve them

Open Science

Dünyanın siyah beyaz yorumundan renkli zamanlara bilim; doğruluğu tartışılmaz bir gerçeği ortaya çıkaran benzersiz bir entelektüel etkinlik olarak önemli bir konuma sahiptir. Bilimsel düşünmenin kökenine indiğimizde gerçeği arama ve gerçeğe ulaşma isteğine vurgu yapan merak duygusuyla karşılaşırız. Bilimin gelişmesi ve güçlenmesi; bu amaçla gerçekleşen düşünme, araştırma ve uygulama etkinlikleriyle olgu ve olayların bir süreklilik içerisinde doğrulanmasına dayanmaktadır.Science is based on the confirmation of phenomena and events in a continuum. In the development of science; the cumulative progress and effective sharing of information comes to the forefront. Within the scope of science, producing new information requires a social approach. Because science has more participants every day so the meaning and importance of science also becomes different. In this sense, the idea of open science, which is based on open access, open data and open source, continues to mediate the socialization of information as well as the purpose of the rapid spread of scientific research results among scientists. In the editorial section, the approach of open science, which has gained momentum in recent years, is evaluated in the context of information retrieval and interaction

The role of theory of mind, emotion knowledge and empathy in preschoolers’ disruptive behavior

Objectives : Research examining disruptive behaviors in clinical groups of preschool and school-aged children has consistently revealed significant difficulties in their emotion knowledge and empathy but intact performance in their theory-of-mind (ToM). However, it is largely not known if these difficulties in emotion knowledge and empathy as opposed to ToM are specific to extreme forms of disruption in clinical groups or rather represent broad deficiencies related to disruptive behaviors in general, including the milder levels exhibited by typically developing children. Milder disruptive behaviors (e.g., whining, arguing, rule-breaking and fighting) in peer contexts might relate to normative variations in socio-cognitive and emotional skills like ToM, emotion knowledge and empathy. To illuminate whether the same pattern of relations observed in clinical samples would arise in typical development, this study aims to examine the role of ToM, emotion knowledge and empathy in typically developing preschoolers’ disruptive behaviors.WOS:000510437900014Scopus - Affiliation ID: 60105072Social Sciences Citation IndexQ3 - Q4ArticleOcak2020YÖK - 2019-2
