Understanding Federation: An Analytical Framework for the Interoperability of Social Networking Sites

Although social networking has become a remarkable feature in the Web, full interoperability has not arrived. This work explores the main 5 paradigms of interoperability across social networking sites, corresponding to the layers in which we an find interoperability. Building on those, a novel analytical framework for SNS interoperability is introduced. Seven representative interoperability SNS technologies are compared using the proposed framework. The analysis exposes an overwhelming disparity and fragmentation in the solutions for tackling the same problems. Although there are a few solutions where consensus is reached and are widely adopted (e.g. in object IDs), there are multiple central issues that are still far from being widely standarized (e.g. in profile representation). In addition, several areas have been identified where there is clear room for improvement, such as privacy controls or data synchronization

Towards an Agent-supported Online Assembly: Prototyping a Collaborative Decision-Making Tool

The promise of online assemblies has been present for years already, and a diversity of tools have attempted to fulfill it. This work aims to reapproach the issue from a novel standpoint that relies on a federated architecture, a real-time collaborative environment, goal-oriented software agents and a consensus-based methodology. Consensuall is a prototype of consensual decision-making collaborative webtool that allows the elaboration, rating and commenting proposals in order to build consensus among a group. The webtool design follows the AgentOriented Software Engineering paradigm. Thus, it proposes the use of software agents as complementary automatic participants fulfilling specific roles, as a way to address decision-making common issues. The article presents Consensuall, a prototype of an agent-based collaborative decision-making webtool within the distributed real-time collaborative platform Apache Wave, providing a proof-of-concept of the adopted approach

Decentralized Autonomous Organization

A DAO is a blockchain-based system that enables people to coordinate and govern themselves mediated by a set of self-executing rules deployed on a public blockchain, and whose governance is decentralised (i.e., independent from central control)

Modelado y simulación de la evolución de valores en sociedades humanas con agentes software

El proyecto aborda, desde una perspectiva multidisciplinar, la integración de métodos y herramientas de los campos de la ingeniería del software, la inteligencia artificial y la sociología. Así, se pretende simular la complejidad de las sociedades humanas desde el diseño de un modelo sociológico. Este modelo tratará de simplificar la realidad extrayendo las características relevantes para el problema objeto de estudio. La simulación social implementará, según las líneas establecidas por dicho modelo, un sistema multiagente en un entorno cerrado. La evaluación del sistema se realizará comparando sus resultados con los datos extraídos de encuestas reales. Se ha experimentado también con otras técnicas de inteligencia artificial, obteniendo distintos módulos de ampliación del sistema: lógica borrosa y salida en lenguaje natural. Esta memoria se complementa con los artículos realizados sobre este proyecto, que se adjuntan al final de la misma

Approaches for Incorporating a Variety of Metadata in Transformer Operation

A plain transformer model typically leverages only one piece of metadata - position encoding - directly in the transformer model. The use of transformers typically involves expensive and complex external scaffolding before or after output generation to avoid issues such as hallucination, irrelevance, etc. This disclosure describes techniques to incorporate a variety of metadata types into the native architecture of transformer models. The additional signals can help avoid hallucinations, improve relevance, and minimize the need of expensive external scaffolding. Generalizing transformer operation to incorporate a diversity of metadata can be achieved in various ways such as adding a metadata embedding layer, conditioning self-attention on the metadata, conditioning with gated self-attention, employing a different encoder-decoder architecture, etc. Different types of metadata can help in different ways to improve the quality of the output generated by the transformer and reduce hallucinations. The techniques described in this disclosure can also support multimodal data, such as images, audio, video, or text, etc., with the metadata used representing the specific mode
