A] paperless system would significantly reduce delays in all aspects of the dissemination cycle. The composition process itself should be speeded up and so should the whole interaction among writers, publishers, and referees (Lan-caster, 1978, p. 127). The BOAI is a public statement and plan of action that calls for``open access to peer-reviewed research articles in all academic fields and the ...

In the last years efforts in econophysics have been shifted to study how network theory can facilitate understanding of complex financial markets. Main part of these efforts is the study of correlation-based hierarchical networks. This is somewhat surprising as the underlying assumptions of research looking at financial markets is that they behave chaotically. In fact it's common for econophysi...

Improving time series forecastingaccuracy is an important yet often difficult task.Both theoretical and empirical findings haveindicated that integration of several models is an effectiveway to improve predictive performance, especiallywhen the models in combination are quite different. In this paper,a model of the hybrid artificial neural networks andfuzzy model is proposed for time series for...

The aim of this communication is to analyse the process of estimation of the adequate time unit in financial series. The problem in time aggregation is the loss of information, that will be acceptable if it is possible to fit a financial model. We present an example of time aggregation problems in Financial Time series over the daily Deutsche Aktienindex (DAX) using three comparative methods: d...

Financial news contains useful information on public companies and the market. In this paper we apply the popular word embedding methods and deep neural networks to leverage financial news to predict stock price movements in the market. Experimental results have shown that our proposed methods are simple but very effective, which can significantly improve the stock prediction accuracy on a stan...

New information technology (IT), especially the internet, have revolutionised the finance industry with the rapid growth of electronic finance. E-finance activities include all types of financial activities carried out over the internet or other public networks, such as online banking, electronic trading, the provision and delivery of various financial products and services (for instance insura...
