Abstract:

Real-Time Process Algebra (RTPA) is a denotational mathematics for the algebraic modeling and manipulations of software system architectures and behaviors by the Unified Data Models (UDMs) and Unified Process Models (UPMs). On the basis of the RTPA specification and refinement methodologies, automatic software code generation is enabled toward improving software development productivity. This paper examines designing and developing the RTPA-based software code generator (RTPA-CG) that transfers system models in RTPA architectures and behaviors into C++ or Java. A two-phrase strategy has been employed in the design of the code generator. The first phrase analyzes the lexical, syntactical, and type specifications of a software system modeled in RTPA, which results in a set of abstract syntax trees (ASTs). The second phrase translates the ASTs into C++ or Java based on predesigned mapping strategies and code generation rules. The toolkit of RTPA code generator encompasses an RTPA lexer, parser, type-checker, and a code builder. Experimental results show that system models in RTPA can be rigorously processed and corresponding C++/Java code can be automatically generated using the toolkit. The code generated is executable and effective under the support of an RTPA run-time library.

Abstract:

Our work aims to present an amazigh pronominal morphological analyzer (APMorph) based on xerox’s finite-state transducer (XFST). Our system revolves around a large lexicon named “APlex” including the affixed pronoun to the noun and to the verb and the characteristics relating to each lemma. A set of rules are added to define the inflectional behavior and morphosyntactic links of each entry as well as the relationship between the different lexical units. The implementation and the evaluation of our approach will be detailed within this article. The use of XFST remains a relevant choice in the sense that this platform allows both analysis and generation. The robustness of our system makes it able to be integrated in other applications of natural language processing (NLP) especially spellchecking, machine translation, and machine learning. This paper presents a continuation of our previous works on the automatic processing of Amazigh nouns and verbs.

Abstract:

The existing techniques for software testing can be used to perform only a particular type of testing, and moreover proficiency is required to write the automation test scripts using these techniques. This paper proposes a novel software testing approach using Aspect-Oriented Programming (AOP) that alone suffices for carrying out most of the types of software testing and thus obliterates the need of using distinctive tools for different types of testing. Nevertheless, AOP is a new programming paradigm and not all testers have the proficiency of working with it. Hence, a domain-specific language named Testing Aspect Generator Language (TAGL) was developed which has got a very low learning curve. Using TAGL, testers can write the testing code in the form of natural language-like statements. Further, the lexical analyzer and parser, written using lex and yacc, convert the TAGL statements into actual testing code in the form of AOP. The proposed approach was applied for the testing of widely used open source projects and remarkable bugs were detected into them. A detailed comparison as to how our approach is effective than the conventional testing techniques is provided.

Abstract:

For every problem mentioned by crew members in an aircraft log book, an associated repair action note is entered in the same log book by a maintenance technician after the problem has been handled. These hand-written repair notes, subsequently transcribed into a database, give an account of the actions undertaken by the technicians to fix the problems. Written in a free-text format with peculiar linguistic characteristics, including many arbitrary abbreviations and missing auxiliaries, they contain valuable information that can be used for decision support methods such as case-based reasoning. We use natural language techniques in our information extraction system to analyze the structure and contents of these notes in order to determine the pieces of equipment involved in a repair and what was done to them. Lexical information and domain knowledge are extracted from an electronic version of the illustrated parts catalog for the particular airplane, and are used at different stages of the process, from the morpholexical analysis to the evaluation of the semantic expression generated by the syntactical analyzer.

Abstract:

Embedded browsers are designed for customized systems to provide web page browsing function for users and have the characteristics of small volume, little resource consumption and high efficiency. These browsers are compatible for network transmission protocols such as HTTP, WAP and etc. and network markup languages such as HTML, JavaScript, XML and etc. Tailored and modified browsers are suitable for various embedded systems, as well as fitting the requirements of users for acquiring information. Language analyzing for HTML is the core technology in browsers and the analyzing result concerns the browsing efficiency. To understand the design process of embedded lexical analyzer to further address the issues of this field, we accomplished the design of lexical analyzer for embedded browser on the platform of ARM2410-S, a platform for embedded system development, and we made cross compilation on PC platform to generate the binary file suitable for ARM structure, then transplant it onto a development board to finish the lexical analyzing function for embedded browser and obtained satisfying result.

Abstract:

This study explores the conceptualization of ‘School’ in the English lexicon of EFL learners, and compares this lexicon to the meanings attributed to the entry School in English dictionaries. Our first objective aimed at identifying the most frequent content words retrieved by Spanish EFL learners in response to the cue-word SCHOOL in a lexical availability/association task, and comparing them with the meanings attributed by dictionaries. Our second objective aimed at ascertaining whether there were gender similarities or differences in the lexical production and the actual words retrieved by males and females. The quantitative analyses applied to the data revealed a common structure in male and female EFL learners’ available lexicon as well as a high correspondence to the meanings attributed to School in dictionaries. However, the qualitative analysis also uncovered typical patterns related to adolescent school life not present in dictionaries as well as vocabulary not shared by males and females but exclusively generated either by males or by females.

Abstract:

Lexical transducers utilise a two-level finite-state network to simultaneously code morphological analysis and morphological generation rewrite rules. Multiple extensions following the verb root can be morphologically analysed as a closed morpheme class using different computational techniques. Analysis of a multiple extension sequence is achieved by trivial analysis, based on any combination of the closed class members, but this produces unnecessary over-generation of lexical items, many of which may not occur in a lexicon. Limiting the extension combinations, in an attempt to represent examples that may actually exist – in terms of both the possible number of extensions in a sequence and the relative ordering of the extensions – leads to a radical reduction in the generation of lexical items while the ability to analyse adequately is maintained. The article highlights details of an investigation based on both trivial analysis and an approach that prevents dramatic overgeneration. The article is based on test data reflecting possible extension sequences and the morphophonemic alternations of these extensions for Northern Sotho, garnered from literature research, lexicographic investigation and the computational morphological analysis of texts.

Abstract:

Future of computing is rapidly moving towards massively multi-core architecture because of its power and cost advantages. Almost everywhere Multi-core processors are being used now-a-days and number of cores per chip is also relatively increasing. To exploit full potential offered by multi-core architecture, the system software like compilers should be designed for parallelized execution. In the past, various significant works have been made to change the design of traditional compiler to take advantages of the future multi-core platform. This paper focuses on adapting parallelism in the lexical analysis phase of the compilation process. The main objective of our proposal is to do the lexical analysis i.e., finding the tokens in an input stream in parallel. We use the parallel constructs available in OpenMP to achieve parallelism in the lexical analysis process for multi-core machines. The experimental result of our proposal shows a significant performance improvement in the parallel lexical analysis phase as compared to sequential version in terms of time of execution.

The authors show that in a Built-In Self-Test (BIST) technique, based on linear-feedback shift registers, when the feedback connections in pseudo-random test-sequence generator and signature analyzer are images of each other and corresponds to primitive characteristic polynomial then behaviors of faults masking remains identical. The simulation results of single stuck-at faults show how the use of such feedback connections in pseudo-random test-sequence generator and signature analyzer yields to mask the same faults.

Advancement in computer technology and corpus linguistics has produced lexical profiling tools which provide opportunity for learners’ corpus to be examined. This study investigated the effects of lexical profiling tools on academic writing and the CEFR levels of the writings. 68 diploma students took part in this experimental study using Timed Informative Writing Test (TIWT). The lexical profiling tools used in the study were English Vocabulary Profile, textinspector.com and Text Analyzer. The results revealed that the students in the experimental group which used the lexical tools perform better in academic writing test and CEFR level than the control group which used the course module. Thus, these tools could help the students to be independent learners and improve their academic writing performance. Keywords: Lexical Profiling Tools, Academic Writing, Lexical knowledge

Abstract:

In cognitive science, understanding language by humans starts with recognition. Without the phase, understanding languages become a very cumbersome task. The task of the lexical analyzer is to read the various input characters grouping them into lexemes and producing an output of a sequence of tokens. But before we discuss lexical analysis further, we should have an overview of this research. Lexical analysis is best described as tokenization that converts a sequence of characters (program) into tokens with identifiable meanings. This study aims to look at the various terms or words related to lexical structure, purpose, and how they are applied to get the required result. The lexical analysis offers researchers an idea of the structural aspect of computer language and its semantic content. The work also talks about the advantages and disadvantages of lexical analysis.

Abstract:

Lexical complexity refers to the various different words employed in the introductions of the undergraduate students’ research articles. The implementation of lexical complexity describes the writers’ overall development of lexical complexity use in the target language. This study aims to find out the employment of lexical complexity in the introductions of undergraduate students’ research articles. It utilized a quantitative design through corpus based analysis.The corpus studied consisted of 134 introductions of undergraduate students’ research articles. The data were analyzed using Web-based Lexical Complexity Analyzer. Then to decide the level of complexity applied in the students’ articles, the results were compared to the lexical complexity of Chinese learners’ oral narratives. The findings show that lexical density, lexical sophistication, and lexical variation are high except for verb variation, noun variation, adjective variation, adverb variation and modifier variation (cf. Lu, 2010, 2012; Ai & Lu, 2013). It is expected that this article could provide information about the lexical complexity which is needed to be improved in the undergraduate students’ research articles.

Abstract:

In this paper, we present calibration and uncertainty evaluation methods for the phase of a radio-frequency comb generator using a calibrated sampling oscilloscope. In addition, we present many solutions that are indispensable for the precise calibration of phase up to 50 GHz. First, we correct the sampling time error, which is the systematic error of the equivalent time sampling system. Second, the frequency response of the oscilloscope is de-convoluted from the measured pulse, and the impedance mismatch between the radio-frequency comb generator and the oscilloscope is calibrated. Finally, we present the calibrated phase of the radio-frequency comb generator and the measurement uncertainty, which demonstrated 95% confidence intervals within ±4.4° up to 50 GHz. The calibrated radio-frequency comb generator, which is traceable to SI units, is used to calibrate a nonlinear vector network analyzer, vector signal analyzer, and oscilloscope. Uncertainties are easily propagated to the measurement uncertainty of other apparatus since it is obtained in the form of covariance.

Abstract:

The article deals with subcultures and their characteristic linguistic properties. Subculture is characterized by a number of designations that serve as a code for communication between “themselves”, as a means of isolating and creating opposition, for self-expression, etc. As most subcultures are represented by young people, youth language absorbs lexical units peculiar for subcultures. Despite the fact that lexicon of subcultures as well as the youth language in general is influenced by the flow of time and changes, it is mostly recorded in the dictionaries, some of it goes into the spoken language, which is used not only by young, but middle and older generation, especially when it comes to notions which emerged at the time of their youth (for example, certain designations in music). Based on the study of German scientists who distinguish the main characteristics of subcultures and inherent for them groups of the most used lexical units, one can observe both coincidence and divergence of lexical units meaning recorded in the dictionaries. Besides specific notions indicating certain characteristics of one or another subgroup (related to music, fashion etc.), subcultures mainly use the youth and spoken language and if necessary a literary one. In the language of subcultures the intensifiers such as, voll, total, echt, tierisch, unheimlich, irre etc are used to reinforce the quality. In the Ukrainian writers’ translations into German one can notice a number of analyzed lexical units typical for the language of subcultures as well as for the youth language in general

Abstract:

The paper seeks to establish the level of lexical complexity in the discourse of Economic Community of West African States (ECOWAS) peacekeeping agreements (EPKA) and to describe the lexical strategies through which the observed complexity is created. Many studies on linguistic complexity focus on second language acquisition, assessment and writing development. But, this article focuses on lexical choices that create complexity capable of hindering reader’s comprehension. It utilizes quantitative and qualitative designs in its analysis of corpus which consists of ten purposively selected EPKA texts. The data are analysed using Web-based Lexical Complexity Analyzer. The findings indicate that the language of the EPKA is complex. The complexity is attributed to high lexical density, lengthy words and long sentences in the corpus. Also, a large proportion of words in the corpus are redundant and vague. It is hoped that this article provides information about the lexical choices needed to improve the discourse of peacekeeping agreements.

Abstract:

Recent analyses of French cliticization (Borer 1981, Aoun 1981, Jaeggli 1981 ) treat object clitic pronouns as lexical affixes. In each case, the clitic is an argument of the verb, generated by a morphological rule which inserts the features PERSON, GENDER, NUMBER, on the verb. The clitic absorbs the Case assigned by the verb. This analysis fails to explain some important facts about French cliticization, in particular the fact that French clitics are not obligatorily arguments of the verb to which they attach. This problem is discussed in relation to Klavans' and Zwicky's analyses of cliticization, and it shown that French clitics seem to have post-lexical, rather than lexical, characteristics.

Abstract:

A syntactic analyzer based on a string grammar is presented. The handling of idioms — a difficult problem for parsers — is more satisfactory than what has been accomplished until now. It appears that it is necessary to distinguish the lexical and syntactic phases of the analysis. Moreover, using a sentence graph structure makes this system really powerfull. There are four main points to this paper: — the architecture of the parser: — the identification of idioms based upon a new categorization of those forms; — the use of a sentence graph structure; — the description of the string grammar analyzer.

Abstract:

Although, morphological analysis is a vital part of natural language processing applications, there are no definitive standards for evaluating and benchmarking Arabic morphological systems. This paper proposes assessment criteria for evaluating Arabic morphological systems by scrutinizing the input, output and architectural design to enables researchers to evaluate and fairly compare Arabic morphology systems. By scoring some state of the art Arabic morphological analyzers based on the proposed criteria; the accuracy scores showed that the best algorithm failed to achieve a reliable rate. Hence, this paper introduced an enhanced algorithm for resolving the inflected Arabic word, identifies its root, finds its pattern and POS tagging that will reduce the search time considerably and to free up the deficiencies identified by this assessment criteria. The proposed model uses semantic rules of the Arabic language on top of a hybrid sub-model based on two existing algorithms (Al-Khalil & IAMA rules). Based on applying the proposed assessment criteria the efficiency and speed have been enhanced where the system achieved up to 1500 words per second in small text up to 3000 words per second in larger documents

Abstract:

Sentiment analysis (SA) is used to extract opinions from a huge amount of data and these opinions are comprised of multiple words. Some words have different semantic meanings in different fields and we call them domain specific (DS) words. A domain is defined as a special area in which a collection of queries about a specific topic are held when user do queries in the data regarding the domain appear. But Single word can be interpreted in many ways based on its context-dependency. Demonstrate each word under its domain is extremely important because their meanings differ from each other so much in different domains that a word meaning from A in one context can change into Z in another context or domain. The purpose of this research is to discover the correct sentiment in the message or comment and evaluate it either it is positive, negative or neutral. We collected tweets dataset from different domains and analyze it to extract words that have a different definition in those specific domains as if they are used in other fields of life they would be defined differently. We analyzed 52115 words for finding their DS meaning in seven different domains. Polarity had been given to words of the dataset according to their domains and based on this polarity they have been recognized as positive negative and neutral and evaluated as domain-specific words. The automatic way is used to extract the words of the domain as we integrated and afterward the comparison to identify that either this word differs from other words as far as domain is concerned. This research contribution is a prototype that processes your data and extracts their domain-specific words automatically. This research improved the knowledge about the context-dependency and found the core-specific meanings of words in multiple fields.

Abstract:

Wanokaka (Wn) and Anakalang (An) languages are two of the seven languages spoken in Sumba, East Nusa Tenggara. Their speakers live in Central Sumba Regency in East Nusa Tenggara Province. Some linguists have considered the two are dialects of Sumba language. In Budasi’s study (2007 2009), however, both of them were quantitatively proved as two diffrent languages spoken in the regency. Based on the lexicostatistics analysis and Swadesh’s classification of language, the relatedness of the two languages was 75,5 % which means that they belong to language family (They are not in dialects relationship). Both languages were hyphotesized originally from Proto Wn-An in Sumba Language Group. Based on this hyphothesis, this paper aims at describing qualitatively the the lexical evidences which differ the two languages. In this study, the the compartive method was applied. The population of the study were the speakers of the two languages. Three informant samples were selected based on a set of criteria. The instruments of the data gathering were three word lists: Swadesh, Nothofer, and Holle; and a tape recorder. Two types of data: secondary and primary, were collected. The obtained data were analysed descriptively and qualitattively. This study concludes that 24.5 % of the total lexicons identified from the three word lists are in different forms that differed the two laguages lexically. Thereare two types of findings. The first findings are a number of lexicons which show the forms of lexical innovation, that is, the forms of cognat sets which show minimum differences in the their phonological patterns; and. The second, is that, the existance of lexical retentions generated from the Proto Wn-An. The whole identified evidences confirmed the quantitatif data findings mentioned in Budasi’s study (2007 and 2009), that is, the Wn-An are two different languages generated directly from the Proto Wn-An within Sumba language Group.

Abstract:

The article examines noun anglicisms and their lexico-semantic integration in the French and Lithuanian languages. The notion of dynamics of the borrowing process and the concept of noun anglicisms are analyzed from the linguistic point of view. The article aims at describing different interpretations of anglicisms by French and Lithuanian linguists, problematics of lexico-semantic anglicisms, and the current approach to lexico-semantic anglicisms in the French and Lithuanian languages. It can be assumed that the intensive usage of anglicisms generates a new linguistic situation in which English terms are widely used in the French and Lithuanian languages. The use of new lexical elements in the French and Lithuanian languages improves text expressiveness and helps to move away from the formality of the text, thus creating a connection with the reader and realizing verbal expressiveness. To sum up, anglicisms in the modern French and Lithuanian languages appear to have a systematic character related to the diachronic and structural development of the language. Their relatively fast assimilation at phonological, morphological and semantic levels appears to be the key part of the borrowing process. A great number of anglicisms seem to be the result of the process of globalization. Anglicisms influence all languages of the world. Naturally, French and Lithuanian are not an exception.

Abstract:

Abstract Software supported procedure for generation of long-time complex test sentences, suitable for testing the instruments for detection of standard voltage quality (VQ) disturbances is presented in this paper. This solution for test signal generation includes significant improvements of computer-based signal generator presented and described in the previously published paper [1]. The generator is based on virtual instrumentation software for defining the basic signal parameters, data acquisition card NI 6343, and power amplifier for amplification of output voltage level to the nominal RMS voltage value of 230 V. Definition of basic signal parameters in LabVIEW application software is supported using Script files, which allows simple repetition of specific test signals and combination of more different test sequences in the complex composite test waveform. The basic advantage of this generator compared to the similar solutions for signal generation is the possibility for long-time test sequence generation according to predefined complex test scenarios, including various combinations of VQ disturbances defined in accordance with the European standard EN50160. Experimental verification of the presented signal generator capability is performed by testing the commercial power quality analyzer Fluke 435 Series II. In this paper are shown some characteristic complex test signals with various disturbances and logged data obtained from the tested power quality analyzer.

Abstract:

The present study is an attempt to empirically test and compare the results of three methods of word association (WA) analysis. Two of the methods – namely, associative commonality and nativelikeness, and lexico-syntactic patterns of associative organization – have been traditionally used in both first language (L1) and second language (L2) associative research and the third one – collocational aspect of associative responses – is a more recent perspective on associative connections. The central assumption behind the study is that each method captures a different aspect of language users’ lexical organization and, in that, their findings may paint a different picture of how the L1 and L2 lexicons compare as proficiency increases. At the same time, the sensitivity of each method to reflect differences related to proficiency may also point to their potential as a research and assessment tool. Three equal size groups of participants ( N = 180) at different proficiency levels – native speakers (NSs), second language (L2) advanced and intermediate learners of English – completed a familiarity and a WA test in writing. The tests contained 36 items equated for lexical class (nouns, verbs, and adjectives) and frequency of occurrence (high, mid, and low). The participants’ WAs generated to familiar vocabulary were analysed in three different ways, following the methods of analysis practiced by each of the three traditions under investigation. In the main, the results showed that examining the lexico-syntactic patterns of associative organization as well as the collocational aspect of associative links are two more ‘promising’ ways of looking at WAs than examining them with respect to their nativelike associative commonality.

Abstract:

The most productive way to encode ablative, privative, and reversative meanings in current Catalan and Spanish is by means of des- prefixation. This paper investigates how these related values are obtained both from a structural and from a conceptual perspective. To analyze the structural behaviour of these predicates, a new neo-constructionist model is adopted: Nanosyntax, according to which lexical items are syntactic constructs. As for the conceptual content associated to these verbs, it is accounted for by means of a non-canonical approach to the Generative Lexicon Theory developed by Pustejovsky (1995 ff.).The core proposal is that des- prefixed verbs with an ablative, a privative, or a reversative meaning share the same syntactic structure, and that the different interpretation of each semantic class emerges as a consequence of the interactions generated, at a conceptual level, between the Qualia Structure of the verbal root and that of the internal argument of the verb.

Abstract:

This study reports the synthesis of monosized Pr nanoparticles with a controllable size ranging from 5 to 20 nm. Pr agglomerates generated by a spark generator first size-selected by a differential mobility analyzer and subsequently sintered in-flight at different temperatures result in spherical and monocrystalline Pr nanoparticles. The dependence of size and size distribution of Pr nanoparticles has been studied as a function of deposition parameters related to spark generator, differential mobility analyzer, and sintering. Transmission electron microscopy, energy-dispersive x-ray analysis, glancing angle x-ray diffraction, and x-ray photoelectron spectroscopy studies confirm that initial Pr agglomerates and the resulting nanoparticles are metallic with d-hexagonal structure and remain stable in air during post-deposition exposure. Incomplete or partially sintered nanoparticles were found to be oxidized, resulting in the formation of amorphous oxide phase due to enhanced oxidation at grain boundaries.
