Although research in other languages is increasing, much of the work subjectivity analysis has been applied to English data, mainly due large body electronic resources and tools that are available for this language. In paper, we propose evaluate methods can be employed transfer a repository across languages. Specifically, attempt leverage on and, by employing machine translation, generate Through comparative evaluations two different (Romanian Spanish), show automatic translation viable...

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

This paper introduces a novel method for measuring semantic relatedness using profiles constructed from salient encyclopedic features. The model is built on the notion that meaning of word can be characterized by concepts found in its immediate context. In addition to being computationally efficient, new has superior performance and remarkable consistency when compared both knowledge-based corpus-based state-of-the-art models.

Blockchain technology has emerged as a new paradigm to build decentralized systems which do not require central authority. It is most popular for enabling Bitcoin and other crypto-currencies. However, blockchain applications span beyond Finance, recently it been applied governance. Blockchain-enabled "Decentralized Autonomous Organizations" (DAOs) have form of collective governance, in communities may organize themselves relying on infrastructure. In this article, we introduce the concept...

Blockchain technologies have generated enthusiasm, yet their potential to enable new forms of governance remains largely unexplored. Two confronting standpoints dominate the emergent debate around blockchain-based governance: discourses characterized by presence techno-determinist and market-driven values, which tend ignore complexity social organization; critical accounts such which, while contributing identifying limitations, consider role traditional centralized institutions as inherently...

Abstract Blockchain technology has enabled a new kind of distributed systems. Beyond its early applications in Finance, it also allowed the emergence novel ways governance and coordination. The most relevant these are so-called Decentralized Autonomous Organizations (DAOs). DAOs typically implement decision-making systems to make possible for their online community reach agreements. As result agreements, DAO operates automatically by executing appropriate portion code on blockchain network...

In this paper, we address the task of crosslingual semantic relatedness. We introduce a method that relies on information extracted from Wikipedia, by exploiting interlanguage links available between Wikipedia versions in multiple languages. Through experiments performed several language pairs, show performs well, with performance comparable to monolingual measures

The current processes of scientific publication and peer review raise concerns around fairness, quality, performance, cost, accuracy. Open Access movement has been unable to fulfill all its promises, a few middlemen publishers can still impose policies concentrate profits. This paper, using emerging distributed technologies such as Blockchain IPFS, proposes decentralized system for open science. proposed would provide (1) reviewer reputation system, (2) an by-design infrastructure, (3)...

Abstract Blockchain technology enables new kinds of decentralized systems. Thus, it has often been advocated as a “disruptive” that could have the potentiality reshaping political, economic, and social relations, “solving” problems like corruption, power centralization, distrust toward political institutions. gradually gaining attention beyond finance is thus applied by range different actors. This includes local, regional, national governments interested in experimenting with...

Scientific publication and its Peer Review system strongly rely on a few major industry players controlling most journals (e.g. Elsevier), databases Scopus) metrics JCR Impact Factor), while keeping articles behind paywalls. Critics to such include concerns about fairness, quality, performance, cost, unpaid labor, transparency, accuracy of the evaluation process. The Open Access movement has tried provide free access published research articles, but aforementioned issues remain. In context,...

In recent years, the increasing need for global coordination has attracted interest in governance of global-scale commons. current context, we observe how online applications are ubiquitous, and emerging technologies enable new capabilities while reshaping sectors. Thus, it is pertinent to ask: could blockchain facilitate extension scaling up cooperative practices commons management this context? order address question, propose a focus on most paradigmatic widely successful examples...

Blockchain technology has enabled a thriving emergent ecosystem of tools and communities actively using decentralized systems. However, most blockchain infrastructure (e.g. Ethereum) requires users to pay some fees execute their desired actions in these novel online services. To which extent an increase the price such negatively affects user activity? Would significant surges deter from blockchain-enabled services? In this work, we study 2020 surge transaction fee Ethereum network, analyze...
