Extracting Features from Social Media Networks Using Semantics
This paper focuses on the analysis of social media content generated by social networks (e.g. Twitter) in order to extract semantic features. By using text categorization to sort text feeds into categories of similar feeds, it has been proved to reduce the overhead that is required to retrieve these feeds and at the same time, it provides smaller pools in which further investigations can be made easier. The aim of this survey is to draw a user profile, by analysing his or her tweets. In this early stage of research, being a pre-processing phase, a dictionary based approach is considered. Moreover, the paper describes an algorithm used in analysing the text and its preliminary results. This …
Spatial [Elements] Decision Support System Used in Disaster Management
Natural disasters profoundly affect the development of human society, they are the most pervasive disasters in the world and they cause the greatest property and human loss. Considering the natural disasters that have struck Romania these years, we believe that is it is absolutely necessary to develop a spatial [elements] decision support system, which would prevent - as much as possible - natural disasters from occurring or would help mitigate their effects. All these objectives are unattainable without effectively applying information and communication technology in the field of natural disasters.
Database Versioning 2.0, a Transparent SQL Approach Used in Quantitative Management and Decision Making
Abstract Managerial decisions are based on accurate information and in today's time raw data is produced even with a stroke of a key. Regardless of the data creating process one needs to know how the information was extracted and which pool of data was used. One important factor is time therefore we need to structure it in layers of data history in such a way that it can be analyzed, (post)process, in order to be able to retrieve valuable information. The simplest way is to use a Database Management System (DBMS), but even with such a management system we face the issue of making it a self-contained database on each version of data added. Our proposed system, a continuation of previous work…
