With the increasing popularity of microblogging services, new research challenges arise in the area of text processing. In this paper, we hypothesize that already existing services for Named Entity Recognition (NER), or a combination thereof, perform well on microposts, despite the fact that these NER services have been developed for processing long-form text documents that are well-structured ...

It is well known that the rapid growth and dissemination of the Internet has resulted in huge amounts of information generated and shared, available in the form of textual data, images, videos or sounds. This overwhelming surge of data is also true for specific areas such as biomedicine, where the number of published documents, such as articles, books and technical reports, is increasing expone...

Researchers typically use traditional lexical scanner and parser tools for projects requiring the recognition of complex text elements. The role relegated to the lexical scanner is usually the simple tokenization while the relationships of the tokens to one another is done by the parser. Implementation of products or features using these tools for VLC can require months of processing or even ye...

This article presents a framework supporting rapid prototyping of multimodal applications, the creation and management of datasets and the quantitative evaluation of classification algorithms for the specific context of gesture recognition. A review of the available corpora for gesture recognition highlights their main features and characteristics. The central part of the article describes a no...

Sketches, whether hand-drawn or computer generated, are a natural and integral part of the design process. Despite this fact, modern day computational design tools are ill-equipped to take full advantage of sketching input. The computational challenges of recognizing sketches are easily overcome by human visual recognition and much insight stands to be gained by emulating human cognitive proces...

We present a tool for annotation of se­ mantic inter­sentential discourse rela­ tions on the tectogrammatical layer of the Prague Dependency Treebank (PDT). We present the way of helping the annotators by several useful features implemented in the annotation tool, such as a possibility to combine surface and deep syntactic representation of sen­ tences during the annotation, a possibili­ ty to ...

Intrusion Detection Systems (IDSs) are security tools widely used in computer networks. While they seem to be promising technologies, they pose some serious drawbacks: When utilized in large and high traffic networks, IDSs generate high volumes of low-level alerts which are hardly manageable. Accordingly, there emerged a recent track of security research, focused on alert correlation, which ext...

This study researches the usefulness of emotion recognition technology and respective data within the retail space. Emotion recognition is a relatively novel technology that promises to pinpoint a subjects emotional state. While the use cases could be many for a retailer there is still little available research on how to implement these tools and how to interpret their data. This study aims to ...
