A framework to generate pseudo-documents suitable for topic modeling is proposed.An instantiation of the framework based on word vector representations is presented.Results of NPMI and F1 obtained are better than those of state-of-the art methods. Sh

Short texts are present in many computer systems. Examples include social media messages, advertisement, Q&A websites, and an increasing number of other applications. They are characterized by little context words and a large vocabulary. As a consequ

Short texts are everywhere on the Web, including messages in social media, status messages, etc, and extracting semantically meaningful topics from these collections is an important and difficult task. Topic modeling methods, such as Latent Dirichlet

This work presents the implementation of an agent based model concept to simulate a sample of the German society under a governmental social transfer system. Subsequently the behavior of the model is analyzed under changing conditions in order to pro

This paper investigates the impact of agents' communication on social simulations using the PAX framework. Previous works investigated the impact of structuring elements (e.g. houses, hospitals, roads, etc) on agents' behaviors. This work extends tha

Agent-based social simulations have been widely used to help social scientists on the understanding of several social phenomena. Traditional approaches to agents most often tackle well the behavioral and the temporal aspects of the carried out simula

This paper investigates a new hybrid evolutionary agent model for agent-based social simulations (ABSS), which incorporates two decision components: (i) sub-symbolic (genetic) and (ii) symbolic (cultural). These components are coherently combined to
