Survey error is known to be pervasive and to bias even simple, but important estimates of means, rates, and totals, such as poverty statistics and the unemployment rate. To summarize and analyze the extent, sources, and consequences of survey error, we define empirical counterparts of key...

Ontology establishes an approach for knowledge representation, sharing and reusing across various applications. It is also the backbone of the semantic web. Therefore, there is a requirement of rapid and effective ontology construction methodology for developing sophisticated knowledge-based and...

Given the growing complexity of tasks and data in NLP there are limited unsupervised learning methods to tackle the problems. In this paper we will look into novel approach to one of the problems as representing sentences in latent space using Recurrent Neural Network (RNN) and Variational Auto...

Information systems ontology is intended to facilitate interoperability among the many applications which are now becoming available on the Internet. In particular, it is intended to facilitate the development of intelligent agents which can automate a large part of the task of a user achieving...

Understanding short texts is crucial to many applications, but challenges abound. Here we focus on short texts which refer to texts with limited context. These short texts are produced including Search queries, Tags, Keywords, Conversation or Social posts and containing limited context. Semantic...

Much of the world's data is textual - in large document archives, in scientific papers, in scattered websites, in social media. The information contained in text is invaluable and yet hard to access. The sheer volume of text means that, unassisted, we cannot hope to read all available sources,...

By mapping messages into a large context, we can compute the distances between them, and then classify them. We test this conjecture on Twitter messages: Messages are mapped onto their most similar Wikipedia pages, and the distances between pages are used as a proxy for the distances between...
