The Accelerating Growth of Online Tagging Systems
Research on the growth of online tagging systems not only is interesting in its own right, but also yields insights for website management and semantic web analysis. Traditional models that describing the growth of online systems can be divided between linear and nonlinear versions. Linear models, including the BA model [A.L. Barabasi, R. Albert, Science 286, 509 (1999)], assume that the averag...
متن کاملDiversity Leads to Accelerating Growth in Online Social Systems
Research on the growth of online social systems not only is interesting in its own right, but also yields insights for website management and web crawling. Traditional models that describing the growth of online systems can be divided between linear and nonlinear versions. Linear models, including the BA model, assume that the average activity of users in a system is a constant independent of s...
متن کاملAccelerating Growth and Size-dependent Distribution of Human Activities Online
Research on human online activities usually assumes that total activity T increases linearly with active population P , that is, T ∝ P (γ = 1). However, we find examples of systems where total activity grows faster than active population. Our study shows that the power law relationship T ∝ P (γ > 1) is in fact ubiquitous in online activities such as micro-blogging, news voting and photo tagging...

مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...
15 صفحه اولVocabulary growth in collaborative tagging systems
We analyze a large-scale snapshot of del.icio.us and investigate how the number of different tags in the system grows as a function of a suitably defined notion of time. We study the temporal evolution of the global vocabulary size, i.e. the number of distinct tags in the entire system, as well as the evolution of local vocabularies, that is the growth of the number of distinct tags used in the...
