Determining the geographic focus of digital media is an essential first step for modern geographic information retrieval. However, publicly-visible location annotations are remarkably sparse in online data. In this work, we demonstrate a method which infers the geographic focus of an online document by examining the locations of Twitter users who share links to the document. We apply our geotag...

Online collaboration on lecture contents has gained much popularity, over the few decades, due to its potential to enhance the learning experience. We propose a novel idea of an online collaboration platform, called Multiscript (MS), for the students and the teacher, on classroom lectures. MS combines two online learning approaches into a single collaboration platform. One approach, called outs...

Geological maps are increasingly published and shared online, whereas tools and services supporting information retrieval and knowledge discovery are underdeveloped. In this study, we developed an ontology of geological time scale by using a RDF (Resource Description Framework) model to represent the ordinal hierarchical structure of the geological time scale and to encode collected annotations...

The Zoom platform provided students in recent online classes, which had been necessitated by COVID-19, with opportunities for active expression using digital annotations. This study explores the experience of elementary reading poetry annotations and its usefulness as social constructivist reading. As such, we conducted a case an out-of-school literature class that used annotations, collected d...

As the scientific literature grows, leading to an increasing volume of published experimental data, so does the need to access and analyze this data using computational tools. The most commonly used method to convert published experimental data on gene function into controlled vocabulary annotations relies on a professional curator, employed by a model organism database or a more general resour...

Motivation: Analysis of next-generation sequencing data often results in a list of genomic regions. These may include differentially methylated CpGs/regions, transcription factor binding sites, interacting chromatin regions, or GWAS-associated SNPs, among others. A common analysis step is to annotate such genomic regions to genomic annotations (promoters, exons, enhancers, etc.). Existing tools...

We present a new approach to evaluate chord recognition systems on songs which do not have full annotations. The principle is to use online chord databases to generate high accurate “pseudo annotations” for these songs and compute “pseudo accuracies” of test systems. Statistical models that model the relationship between “pseudo accuracy” and real performance are then applied to estimate test s...

Interpreting an utterance sometimes depends on the presence and nature of non-linguistic actions. In this paper, we motivate and develop a semantic model of embodied interaction in which the contribution that non-linguistic events make to the content of the interaction is dependent on their rhetorical connections to other actions, both linguistic and non-linguistic. We support our claims with c...

The paper reports the outcomes of a study with law school students to annotate a corpus of legal cases for a variety of annotation types, e.g. citation indices, legal facts, rationale, judgement, cause of action, and others. An online tool is used by a group of annotators that results in an annotated corpus. Differences amongst the annotations are curated, producing a gold standard corpus of an...
