A ventriloquism perspective on Natural Language Processing

A ventriloquism perspective on Natural Language Processing

Authors: Ștefan Trăușan-Matu
( 9 downloads)
Abstract

Natural language interfaces and, in general, Natural Language Processing (NLP) state of the art applications cannot handle satisfactory (if they can at all) conversational implicatures, illocutionary force, stylization, parody, inner disguised polemic, disguised dialogue and other similar phenomena. Considering the ventriloquism perspective in the context of the dialogic-polyphonic theories of Mikhael Bakhtin may provide a basis on trying to cope with such phenomena. The paper introduces some basic ideas of Bakhtin related to ventriloquism in an extended sense, discusses the approaches based on ventriloquism in other domains than NLP, then it analyzes several NLP applications from the perspective of this concept. Several ideas on how the analysis of ventriloquism might be done in NLP are introduced.

Software system for the automatic and computer assisted diagnosis of some severe abdominal affections, based on ultrasound images

Software system for the automatic and computer assisted diagnosis of some severe abdominal affections, based on ultrasound images

Abstract

In this article we describe specific methods for the characterization and computer assisted diagnosis of some severe abdominal diseases, based on ultrasound images and the corresponding software system. The objective of our research is to build an instrument for the non-invasive diagnosis, based on virtual biopsy, of some severe abdominal diseases such as the cirrhosis, the hepatocellular carcinoma (HCC) and the colorectal tumors. The gold standard for the diagnosis of these affections is the classical biopsy, but this is invasive, dangerous. Ultrasonography is a medical-imaging based investigation method that is noninvasive, inexpensive, safe and thus repeatable. Texture is an important property of the human body tissues, able to reveal subtle characteristics upon the pathology. We defined the imagistic textural model of these affections, using the information obtained from ultrasound images. Based on the imagistic textural model, we assessed the possibility of performing automatic recognition of the considered affections both in supervised and unsupervised manner, the purpose of the latter approach being that of discovering the severity grades of the diseases. The resulted accuracy was above 90% in most of the cases.

Keywords: Automatic and computer assisted diagnosis, non-invasive characterization, ultrasound images, texture, virtual biopsy, classification performance
Visual tools for Software Development in GIS applications

Visual tools for Software Development in GIS applications

Authors: Mihai Gheorghe, Marian Dârdală
( 10 downloads)
Abstract

This paper aims to showcase a set of features which enables users to develop custom processing models using a specific interface for the workflow. The component presented in this paper, part of the ArcGIS software suite, is called ModelBuilder and allows a visual description of the processing flow, which enable users who do not have extensive programming knowledge to define custom processing models. The tool is also addressed for experienced programmers by having the ability to include scripts within the models and setting them parameters for integration with the workflow. This way, the models can be run either as stand-alone tools, on demand using specific interaction routines - GIS Add-ins, or can be embedded in WebGIS applications by exporting them as geoprocessing services and run through ArcGIS Server or through Cloud services provided by ESRI (the company that develops ArcGIS).

Evaluating lightweight optical hand tracking for Virtual Reality rehabilitation

Evaluating lightweight optical hand tracking for Virtual Reality rehabilitation

Authors: Oana Ferche, Alin Moldoveanu, Florica Moldoveanu
( 9 downloads)
Abstract

As part of the TRAVEE (Virtual Therapist for Neuromotor Rehabilitation through Augmented Feedback) project we require a device for a precise tracking of the movements of the human hand. We concluded that the most appropriate for our purpose (due to its lightweight design and ease of use) would be a solution based on optical tracking. In this paper, we presented the way in which we evaluated two such optical tracking devices: Leap Motion and Intel RealSense. We used this method because we believe it fits the best our particular scenario.

Semantic Analysis of Source Code in Object Oriented Programming. A Case Study for C#

Semantic Analysis of Source Code in Object Oriented Programming. A Case Study for C#

Authors: Claudiu Epure, Adrian Iftene
( 10 downloads)
Abstract

This paper describes the CSCRO ontology and the Sharp RDF system, used together to semantically analyze the C# source code. The CSCRO ontology formally describes the domain of C# programming language, in which the concepts are represented as classes, properties and individuals. The purpose of the project is to provide the ability to retrieve information about the source code in form of metadata. The first step to achieve this is to incrementally build a graph-oriented knowledge-base from plain source code, based on the ontology. This is done using a convenient format like the Resource Description Framework (RDF). Having the knowledge base in place, it is easy to query the system (e.g. SPARQL) about its interacting components and services, retrieving data in a machine readable format. Going further, an answering mechanism could be applied for enabling natural language questions on the knowledge base.

( 11 downloads)
Abstract

Developing web interactive systems is a laborious work that requires the management of complex projects including data models, task models, and the user interface. In this paper are presented the main features of an online support system for project management, the system being intended to offer an extended functionality - by the means of a “cluster” of Web services - in handling complex information organized in arborescent structures. The main goal of the project is the implementation of a scalable project management system (within an organization or a consortium) relying on a service-oriented architecture (SOA) that offers compatibility/portability over heterogeneous platforms, Web engines and Database systems.

Keywords: SOA, WSDL, project management
Methodology for Identification and Evaluation of Web Application Performance Oriented Usability Issues

Methodology for Identification and Evaluation of Web Application Performance Oriented Usability Issues

Authors: Mihaela Ciugudean, Dorian Gorgan
( 9 downloads)
Abstract

This paper aims to illustrate a methodology for identifying and assessing a set of performance issues encountered in a particular web application, with impact on the usability level. Throughout this methodology, several visual techniques are determined and investigated by taking advantage of the functionalities offered by available performance monitoring tools such as JMeter and VisualVM. This way, the major performance concerns and their impact on the web application usability are easily determined. Therefore, by identifying the problematic parts of a system, corrective measures could be taken, particularly designed to operate on the root cause of the problem, thus leading to the targeted objective. Moreover, some performance improvement recommendations are further on presented in order to enhance the overall usability and the user experience, the actual goal of the research and development activities conducted. These performance concerns might be designed and implemented after fixing the critical parts causing usability problems and consequently, maximizing the user satisfaction and comfort when exploring the functionalities offered by a particular web application.

Methods for Modelling Sketches in the Collaborative Prototyping of User Interfaces

Methods for Modelling Sketches in the Collaborative Prototyping of User Interfaces

Authors: Jorge Luis Pérez Medina

Abstract

Cross-functional teams with different technical backgrounds working on cross-platform environments require the production of flexible modeling of user interfaces in early steps of a design process. We observe that model-driven engineering (MDE) is currently gaining acceptance in many domains. However, existing solutions have no support for collaborative prototyping of user interfaces by sketching recognition for multiple stakeholders (e.g., designers, developers, final end users) working with heterogeneous computing platforms (e.g., smartphones, tablets, laptops, desktop), on different, perhaps separate or shared, interaction surfaces (e.g., tables, whiteboards) in a co-located way or remotely. This requires flexibility to explore and reuse vague and uncertain ideas as model sketching. This paper presents UsiSketch, an MDE method for modeling sketches that offers the following novel features resulting from a requirement elicitation process: sketching recognition on different surfaces based on a new recognition algorithm that accommodates very large surfaces and model-based design of user interfaces with collaboration.

Recovering implicit thread structure in chat conversations

Recovering implicit thread structure in chat conversations

Authors: Andrei Dulceanu
( 10 downloads)
Abstract

The analysis of chat conversations is a cumbersome task because of the number of different discussion threads that may occur at a certain moment. While most participants in a chat session tend to discuss one topic at a time, interferences appear due to environment asynchrony. This paper presents an approach for recovering implicit thread structure of a chat conversation by using a pipeline centered on semantic similarity between short phrases. Temporal, social and lexical aspects of the conversation are blended in a single model which predicts for each utterance not only the thread it belongs to, but also the utterance most related to in its thread.

Aggregating textual and video data from movies

Aggregating textual and video data from movies

Abstract

In this paper, we present an automatically annotated corpus based on movie screenplays (script) and subtitles. We extract the relevant textual information from movie screenplays and subtitles using a regular expression approach. Then, we synchronize screenplays with subtitles using a matching algorithm, thus bounding each sentence from a script between two temporal limits. We also developed an application using the corpus to test our approach and to show practical situations where this corpus is useful. The application employs topic detection and it involves searching for a specified topic in the movie text and marking the topic as non-existent, episodic or primary topic for the analyzed text. The major problem we faced while working on this system was the unexpected structure of the screenplay sheets as this kind of files are not entirely written using a standardized format which can be easily parsed and structured automatically. Some types of errors can be overcome with regular expressions, but there are other errors that need a machine learning approach to be surpassed.

Recommendation Technique for the “Cold-Start” Problem

Recommendation Technique for the “Cold-Start” Problem

Authors: Mihaela Colhon, Adrian Iftene
( 9 downloads)
Abstract

Usually, users that benefit from a Recommender System outputs only get a list of items that the system assumes best match their needs, without having any clue regarding how the system managed to figure out what they like. In this paper, we propose a mechanism that generates content-based recommendations organized on levels of similarities with the selected product in order to let the user decide about what similarity degree (s)he wants to explore. We demonstrate empirically that our proposed mechanism can ensure good performance for a recommendation technique under the cold-start conditions.

Reading Space Secrets - A Serious Game Centered on Reading Strategies

Reading Space Secrets - A Serious Game Centered on Reading Strategies

Abstract

Serious games based on reading strategies are an efficient alternative for improving students’ capabilities of text understanding. In today’s industry and academic environments, there are various games that target reading strategies, but unfortunately most keep focus only on the educational component, leaving the user experience behind. These games are not appealing to young students and thus, may not fully achieve the desired outcomes. The serious game described in this paper puts emphasis on the user experience, tightly coupled with keeping a high standard of its educational focus. Preliminary validation experiments denote a high user acceptance of the proposed educational scenario as an alternative to the traditional scenario that consists of a lecture followed by a self-explanation of the input narrative text.

Abstract

In this paper we present the efforts of creating a syntactic parser with a very good performance on Romanian sentences. Instead of creating a parser from scratch, we decided to test the freely available existing ones and to subject them to tuning, feeding them with linguistic information in the form of features (transitivity/intransitivity, semantic class, subcategorization frames, etc.). The parsers are trained and tested on the Romanian treebank in the Universal Dependencies format. We present here, as on-going work, some partial results of our endeavour: after including only several features, we got encouraging results. We also discuss some other features that can be added to the parser in order to further improve its performance, with the final aim of attaining a reliable tool for syntactic analysis of sentences, as a task per se, and also for their use in various applications involving natural language processing.

Abstract

In previous work, we proposed a method to facilitate the tabletop collaborative prototyping of model-based user interfaces in early steps of the design process when multiple stakeholders have only a vague goal in mind of what should be produced. We also developed UsiSketch, a Java-based software supporting our modeling sketching method. In this paper, we present the main functionalities and the software architecture of UsiSketch.

Abstract

A large number of people of all ages participate in social networks with different aims. The number of users attending the on-line social networks is increasing daily. University students also spend a lot of time on Online Social Networks (OSN), and this can cause them to become potential addicts. The aim of this paper is twofold: (1) to analyze the relationship between the Facebook dependence and the negative consequences on the students’ university work and (2) to analyze the measurement invariance across gender. The results of the empirical study that used a sample from the Technical University of Civil Engineering in Bucharest show a significant difference between male and female students regarding the Facebook dependence and its negative effects on the work of students.

Keywords: Facebook, social networking websites, gender differences, comparative study
