  1. Alternative Learning Approaches for Electronic Learning Environments in Smart Schools: Survey Results

    Kemalatha Krishnasamy; Sai Peck Lee
    Abstract: Learning styles have been studied for many years; however, studies focusing on learning styles based on multiple intelligences theory for electronic learning are very limited. Knowledge of learning styles is important and may be useful in the development and conduct of e-learning in higher learning institutions and schools. The purpose of this study was to establish baseline information regarding the distribution of learning styles among lower secondary students at selected smart schools in Malaysia. A secondary purpose was to establish for these same individuals their stated preferred learning mode for learning online. A purposive sample (judgment sampling) was chosen...

  2. Production Planning by Shuffle Operation

    Adalbert Golomety; Alina Pitic; Iulia Golomety; Antoniu Pitic
    Abstract:- This paper presents an implementation of shuffle operation in production planning.

Key-Words:- shuffle, production phases, production planning, linguistic model, execution time. 1 Linguistic Model of Production Process By production process we understand the transformation action of resources (material, energy) in final products according of a fabrication recipe. The model that we will show has the purpose to determine the set of actions strings that represents right evolutions of...

  3. Semantifying OpenStreetMap

    Alkyoni Baglatzi; Margarita Kokla; Marinos Kavouras
    Abstract. OpenStreetMap is one of the best examples of Volunteered Geographic Information. Its success relies on the ease of use and the freedom it provides. Users are supposed to geolocate their Points Of Interest and annotate them with a tag. There is no certain vocabulary or ontology of the tags that users have to commit to. The whole tagging process is done in a bottom-up manner in which the community on a wiki basis discusses this issue. Allowing users to use tags freely increases the usability of OpenStreetMap but at the same time causes semantic interoperability problems. What is needed,...

  4. TypeCraft: Collaborative Databasing and Resource Sharing for Linguists

    Dorothee Beermann; Pavel Mihaylov
    Abstract. We present a linguistic application that uses web technologies to promote the reuse of research data in the form of Interlinear Glossed Text (IGT), which is a well-established data format within philology and the structural and generative fields of linguistics. Here we present the modules and procedures of the online database TypeCraft. 3 IGT is a sought after commodity in NLP and an integral part of scholarly linguistic work. It not rarely represents the only structured data available for less-resourced or endangered languages. While archiving of structured data from endangered languages is already well on its way [2], the...

  5. Enhancing the expressiveness of linguistic structures

    J. Mora; J. A. Ramos; G. Aguado De Cea
    Abstract. In the information society large amounts of information are being generated and transmitted constantly, especially in the most natural way for humans, i.e., natural language. Social networks, blogs, forums, and Q&A sites are a dynamic Large Knowledge Repository. So, Web 2.0 contains structured data but still the largest amount of information is expressed in natural language. Linguistic structures for text recognition enable the extraction of structured information from texts. However, the expressiveness of the current structures is limited as they have been designed with a strict order in their phrases, limiting their applicability to other languages and making them...

  6. Fuzzy Evaluation for the Rate of Aggregative Risk in Software Development

    Lily Lin; Huey-ming Lee; Shu-yen Lee; Tsung-yen Lee
    Abstract:- In this paper, we present a new fuzzy assessment method to tackle the rate of aggregative risk in fuzzy circumstances by fuzzy sets theory during any phase of the software development life cycle. Because the proposed method directly uses the fuzzy numbers rather than the linguistic values to evaluate, it can be executed much faster than before. The proposed fuzzy assessment method is easier, closer to evaluator real thinking and more useful than the ones they have presented before. Key-Words:- Fuzzy assessment; Risk analysis; Rate of aggregative risk. 1

  7. A System Description of Natural Language Query over DBpedia �

    Nitish Aggarwal; Paul Buitelaar
    Abstract. This paper describes our system, which is developed as a first step towards implementing a methodology for natural language querying over semantic structured information (semantic web). This work focuses on interpretation of natural language queries (NL-Query) to facilitate querying over Linked Data. This interpretation includes query annotation with Linked Data concepts (classes and instances), a deep linguistic analysis and semantic similarity/relatedness to generate potential SPARQL queries for a given NL-Query. We evaluate our approach on QALD-2 test dataset and achieve a F1 score of 0.46, an average precision of 0.44 and an average recall of 0.48.

  8. Indoor Scene Knowledge Acquisition using a Natural Language Interface

    Saranya Kesavan; Nicholas A. Giudice
    Abstract. This paper proposes an interface that uses automatically-generated Natural Language (NL) descriptions to describe indoor scenes based on photos taken of that scene from smartphones or other portable camera-equipped mobile devices. The goal is to develop a non-visual interface based on spatio-linguistic descriptions which could assist blind people in knowing the contents of an indoor scene (e.g., room structure, furniture, landmarks, etc.) and supporting efficient navigation of this space based on these descriptions. In this paper, we concentrate on understanding the most salient content of a stereotypic indoor scene that is described by an observer, categorizing the description strategies...

  9. Language experience changes subsequent learning

    Onnis, Luca; Thiessen, Erik
    What are the effects of experience on subsequent learning? We explored the effects of language-specific word order knowledge on the acquisition of sequential conditional information. Korean and English adults were engaged in a sequence learning task involving three different sets of stimuli: auditory linguistic (nonsense syllables), visual non-linguistic (nonsense shapes), and auditory non-linguistic (pure tones). The forward and backward probabilities between adjacent elements generated two equally probable and orthogonal perceptual parses of the elements, such that any significant preference at test must be due to either general cognitive biases, or prior language-induced biases. We found that language modulated parsing preferences...

  11. From shared contexts to syntactic categories: The role of distributional information in learning linguistic form-classes

    Reeder, Patricia A.; Newport, Elissa L.; Aslin, Richard N.
    A fundamental component of language acquisition involves organizing words into grammatical categories. Previous literature has suggested a number of ways in which this categorization task might be accomplished. Here we ask whether the patterning of the words in a corpus of linguistic input (distributional information) is sufficient, along with a small set of learning biases, to extract these underlying structural categories. In a series of experiments, we show that learners can acquire linguistic form-classes, generalizing from instances of the distributional contexts of individual words in the exposure set to the full range of contexts for all the words in the...

  12. Multilingual children with hearing loss: Factors contributing to language use at home and in early education

    Crowe, Kathryn; McKinnon, David H; McLeod, Sharynne; Ching, Teresa YC
    Understanding the relationship between children’s cultural and linguistic diversity and child, caregiver, and environmental characteristics is important to ensure appropriate educational expectations and provisions. As part of the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study, children’s caregivers and educators completed questionnaires on demographic characteristics, including the communication mode (oral, manual, or mixed) and languages used in home and early educational environments. This article reports an exploratory analysis to examine factors associated with language use and communication mode of children at 3 years of age. A Chi Square Automatic Interaction Detector (CHAID) analysis was performed on data from 406...

  13. Effects of Environmental Stimulation on Infant Vocalizations and Orofacial Dynamics at the Onset of Canonical Babbling

    Harold, Meredith Poore; Barlow, Steven M.
    The vocalizations and jaw kinematics of 30 infants aged 6–8 months were recorded using a Motion Analysis System and audiovisual technologies. This study represents the first attempt to determine the effect of play environment on infants’ rate of vocalization and jaw movement. Four play conditions were compared: watching videos, social contingent reinforcement and vocal modeling with an adult, playing alone with small toys, and playing alone with large toys. The fewest vocalizations and spontaneous movement were observed when infants were watching videos or interacting with an adult. Infants vocalized most when playing with large toys. The small toys, which naturally...

  14. Phonological deficits in specific language impairment and developmental dyslexia: towards a multidimensional model

    Ramus, Franck; Marshall, Chloe R.; Rosen, Stuart; van der Lely, Heather K. J.
    An on-going debate surrounds the relationship between specific language impairment and developmental dyslexia, in particular with respect to their phonological abilities. Are these distinct disorders? To what extent do they overlap? Which cognitive and linguistic profiles correspond to specific language impairment, dyslexia and comorbid cases? At least three different models have been proposed: the severity model, the additional deficit model and the component model. We address this issue by comparing children with specific language impairment only, those with dyslexia-only, those with specific language impairment and dyslexia and those with no impairment, using a broad test battery of language skills. We...

  15. Age, Sex, and Verbal Abilities Affect Location of Linguistic Connectivity in Ventral Visual Pathway

    Burman, Douglas D.; Minas, Taylor; Bolger, Donald J.; Booth, James R.
    Previous studies have shown that the strength of connectivity between regions can vary depending upon the cognitive demands of a task. In this study, the location of task-dependent connectivity from the primary visual cortex (V1) was examined in 43 children (ages 9–15) performing visual tasks; connectivity maxima were identified for a visual task requiring a linguistic (orthographic) judgment. Age, sex, and verbal IQ interacted to affect maxima location. Increases in age and verbal IQ produced similar shifts in maxima location; in girls, connectivity maxima shifted primarily laterally within the left temporal lobe, whereas the shift was primarily posterior within occipital...

  16. 15-Month-Olds’ Transfer of Learning between Touch Screen and Real-World Displays: Language Cues and Cognitive Loads

    Zack, Elizabeth; Gerhardstein, Peter; Meltzoff, Andrew N.; Barr, Rachel
    Infants have difficulty transferring information between 2D and 3D sources. The current study extends Zack et al.’s (2009) touch screen imitation task to examine whether the addition of specific language cues significantly facilitates 15-month-olds’ transfer of learning between touch screens and real-world 3D objects. The addition of two kinds of linguistic cues (object label plus verb or nonsense name) did not elevate action imitation significantly above levels observed when such language cues were not used. Language cues hindered infants’ performance in the 3D→2D direction of transfer, but only for the object label plus verb condition. The lack of a facilitative...

  17. Effects of Noise Reduction on AM and FM Perception

    Ives, D. Timothy; Calcus, Axelle; Kalluri, Sridhar; Strelcyk, Olaf; Sheft, Stanley; Lorenzi, Christian
    The goal of noise reduction (NR) algorithms in digital hearing aid devices is to reduce background noise whilst preserving as much of the original signal as possible. These algorithms may increase the signal-to-noise ratio (SNR) in an ideal case, but they generally fail to improve speech intelligibility. However, due to the complex nature of speech, it is difficult to disentangle the numerous low- and high-level effects of NR that may underlie the lack of speech perception benefits. The goal of this study was to better understand why NR algorithms do not improve speech intelligibility by investigating the effects of NR...

  18. Las capillas de las universidades laborales como recuperación de la modernidad en la arquitectura española del siglo XX

    Río Vázquez, Antonio Santiago
    Las Universidades Laborales forman un conjunto singular dentro de la historia de la arquitectura española del siglo veinte debido a las circunstancias políticas y sociales en las que surgieron. Siguiendo los principios ideológicos falangistas y los del nacional catolicismo, se plantea como esencial la existencia de un espacio dedicado al culto, como complemento de la función docente en el diseño pedagógico y arquitectónico de los nuevos centros. Las necesidades programáticas demandadas por estos centros precisan de una respuesta arquitectónica hasta el momento inexistente y difícilmente resoluble con las metodologías anteriores. Los primeros intentos para dotar de una expresión formal y funcional...

  19. Negotiating roles in pharmacy practice: interactions across linguistic and cultural barriers.

    Stevenson, F; McNulty, G; Leontowitsch, M
    There has been relatively little discussion of the effects of cultural and linguistic differences on communication in consultations. Moreover, communication in community pharmacy is largely under-researched. This study explores interactions between pharmacists, pharmacy assistants and patients conducted across cultural and linguistic barriers. We drew on a data set collected in a pharmacy in London. The data consisted of 12 video recorded consultations in which patients spoke in Sylheti (a dialect of Bengali), the pharmacists spoke in English and pharmacy assistants used both languages. These data were supplemented with focus groups. Despite the fact that the pharmacy assistant was the only...

  20. An Interval Type-2 Fuzzy Logic Based System for Model Generation and Summarization of Arbitrage Opportunities in Stock Markets

    Dario Bernardo; Hani Hagras; Edward Tsang
    Abstract—Today stock market exchange and finance are centers of attention all over the world. In finance, arbitrage is the practice of taking advantage of a price misalignment between two or more stock markets where profit can be earned by striking a combination of matching deals that capitalize upon the misalignment. If one strikes when misalignment has been observed, such deals are practically risk-free. However, when risk-free profit is around, everyone would compete to take advantage of it. Therefore, the question is whether arbitrage opportunities can be predicted; after all, misalignment does not happen instantaneously. Furthermore, financial operators do not like...
