AutoWebS: um Ambiente para Modelagem e Geração Automática de ServiçosWeb Semânticos

Typically Web services contain only syntactic information that describes their interfaces. Due to the lack of semantic descriptions of the Web services, service composition becomes a difficult task. To solve this problem, Web services can exploit the use of ontologies for the semantic definition of service s interface, thus facilitating the automation of discovering, publication, mediation, invocation, and composition of services. However, ontology languages, such as OWL-S, have constructs that are not easy to understand, even for Web developers, and the existing tools that support their use contains many details that make them difficult to manipulate. This paper presents a MDD tool called AutoWebS (Automatic Generation of Semantic Web Services) to develop OWL-S semantic Web services. AutoWebS uses an approach based on UML profiles and model transformations for automatic generation of Web services and their semantic description. AutoWebS offers an environment that provides many features required to model, implement, compile, and deploy semantic Web services

Certificação de composições de serviços web semânticos

This thesis presents a certification method for semantic web services compositions which aims to statically ensure its functional correctness. Certification method encompasses two dimensions of verification, termed base and functional dimensions. Base dimension concerns with the verification of application correctness of the semantic web service in the composition, i.e., to ensure that each service invocation given in the composition comply with its respective service definition. The certification of this dimension exploits the semantic compatibility between the invocation arguments and formal parameters of the semantic web service. Functional dimension aims to ensure that the composition satisfies a given specification expressed in the form of preconditions and postconditions. This dimension is formalized by a Hoare logic based calculus. Partial correctness specifications involving compositions of semantic web services can be derived from the deductive system proposed. Our work is also characterized by exploiting the use of a fragment of description logic, i.e., ALC, to express the partial correctness specifications. In order to operationalize the proposed certification method, we developed a supporting environment for defining the semantic web services compositions as well as to conduct the certification process. The certification method were experimentally evaluated by applying it in three different proof concepts. These proof concepts enabled to broadly evaluate the method certification

A esquina do povo de alt’lam: aprimoramento racial e moral no movimento espírita natalense

A partir de um conjunto de dados obtidos em pesquisa, o texto deseja salientar uma face pouco examinada pelos estudiosos do espiritismo no Brasil: aquela dos grupos espíritas que cultuam extraterrestres. Examina a narrativa Rebelião de Lúcifer, escrita pelo médium potiguar Jan Val Ellam. Sustenta que esta atualiza noções importantes em relação a narrativas de salvação anteriores construídas pelo espiritismo. Destaca em especial o aprimoramento racial e moral através da reencarnação em distintos corpos humanos e em diferentes planetas. Examina-os a partir das noções de exílio planetário e de evolução racializada. Argumenta que Jan Val Ellam as atualiza através da categoria nativa Povo de Alt’Lam e através de bricolagem com outros campos semânticos, notadamente a ufologia e a fi cção científica

A representação social do cuidado no Programa Saúde da Família na cidade do Natal

The aim of this study was to learn about the social representations of the care provided by the Family Health Program (FHP) in the city of Natal, Brazil and determine how these representations guide the daily actions of doctors, dentists, nurses, nurse s assistants and oral health assistants during the work process. In this sense, we used the theoreticalmethodological approach to the Theory of Social Representations. For data collection, we used the following instruments: a two-part questionnaire, where the first part recorded sociodemographic data and the second part was adapted to the free word association technique (FWAT), which was applied to 90 professionals belonging to 18 FHP units. Interviews were also used as collection instruments. These were based on inductive stimuli and on direct observations of 30 of these professionals. After a superficial reading of the material, we constructed a corpus from which ten categories emerged. To analyze FWAT we used lexicographic analysis, combining frequency and the mean order of responses. The interviews and sociodemographic variables were analyzed using content analysis and descriptive statistical analysis, respectively. The study showed that the central nucleus of the social representation in question is composed of the elements attention, receptivity and love, revealing that the subjects have different understandings of the FHP care process and that the knowledge accumulated in this respect is supported by an approximate vision of the meaning of care. However, traditional elements with trivializing connotations about care predominate, which compromises the development of strategies to overcome traditional practices. In the set of analyses, we were able to capture the invariance of a contradiction: on one hand, professionals know and affirm the importance of providing care for FHP patients; on the other, the experience of daily practice translates into the negation of this concept. In this contradictory context, professionals build gradual and successive syntheses that allow them to act and affirm themselves by associating information from their academic formation, structured knowledge acquired in other experiences, values and symbols of their daily routine. Thus, they shape and reshape themselves, according to what is concretely and specifically required, at the same time both plural and multiple. The composition of the central nucleus indicates that any measure that intends to modify attitudes that is, the daily actions of FHP professionals with respect to care must take into account and give priority to the debate about the redefining of the semantic fields of the central nucleus (love/attention/receptivity and humanization), especially those of love and attention

Representações sociais, relações de gênero e programas de assistência e educação à saúde da mulher no climatério em Natal/RN

Climacteric is the name of the period of the human life that it is going from the 40 years old, approximately, until the 65 years old. Though, for besides a biological phase of the woman's life, the climacteric is an object of the social world that is rendered to different apprehensions and readings on the symbolic plan. In this study, it was looked for to know the social representations, that health' professionals acting in the programs of the climacteric and the users of those same services, build in respect of that purpose. Besides, it tried to be seen that the social hegemonic representation that guides the actions and the agents' attitudes in the practices of attendance and education for the woman's health in the climacteric in the extent of the investigated institutions. The data were collected through interviews, questionnaire, focal discussion group and direct observation. The observation field was constituted by the three institutions that develop the attendance and education for the woman's health in the climacteric phase, in the city of Natal. A gender perspective was also been adopted, sought to evidence as the cognitive structures that assure the masculine power reproduction, pronounce to the social representations to build a sense to the investigated purpose. It was verified that the social representations of the climacteric are built mainly around the semantic fields old age and disease. For the health professionals, the meaning of the simbol old age carries the marks of the indentified system of the middle class employed, but also, of the feminine habitus that guides them to have an ethical and aesthetic apprehension of their own body. The climacteric, in that way, is seen as a difficult phase , a painful event that scares . For the women attended by those professionals, the sign old age means feeling emphasis from the biological climacteric aspects, in other words, the sensations and signs that forbid the body to accomplish certain linked basic life functions. Along the whole course of this thesis, it was verified that the climacteric is a complex phenomenon that needs to be faced as such. While cultural phenomenon, it is urgent to look for means to help to combat the centrality of the professional representations that face the climacteric as old age and disease, particularly in the field of health

A Tessitura de sentidos: representação social de licenciados do curso deletras da UFRN sobre o ensinar

En esta investigación, se busca comprender los procesos de formación de pregrado del Curso de Cartas da UFRN, de estas representaciones sociales acerca de los estudiantes de enseñanza. Por lo tanto, el objetivo fue conocer y analizar las representaciones sociales de curso de pregrado UFRN Cartas sobre la enseñanza. Por lo tanto, se aplica la Técnica de Libre de Palabras Asociación (TALP) con 20 participantes, después de haber sido probados individualmente, utilizando como estímulo palabra "enseñar" y limitar el número de invocaciones a 03 palabras por participante. Esta técnica fue elegida porque es una técnica proyectiva que permite la reducción y racionalización permite acceder al campo semántico de las representaciones sociales, en nuestro caso, en la enseñanza del de pregrado do Curso de Cartas da UFRN. Por lo tanto, llegamos a total de 60 llamadas, análisis de frecuencia después de 41 y 24 después de un análisis del significado que se utilizaron en otro procedimiento aplicado en esta investigación, las calificaciones de Procedimiento de Múltiples Calificaciones (PCM). Estas palabras, sobre la base de las justificaciones de las evocaciones y significados que atribuyen participantes en la investigación, se dividieron en 4 campos semánticos: Campo 1: Aspectos técnicos de la enseñanza, Campo 2: aspectos volitivos, Campo 3: aspectos relacionales de la enseñanza y de Campo 4: Elementos del campo. El PCM se aplicó de forma individual, con 50 estudiantes. Para el análisis de los datos generados, utilizamos Análisis Multidimensional (MDS) para la Escala Multidimensional de Evaluación Análisis gratuito (MSA: Multidimensional Scalogram Analysis) y el análisis de clasificación selectiva de los espacios menores (SSA: Smallest Space Analysis). El mapa generado por el análisis de MSA fue dividido en tres regiones: Aspectos de los aspectos de enseñanza, capacitación y asistencia técnica de los promotores de la profesionalización, la primera región que tiene una sub-regionalización llamada dimensión negativa. El mapa de la SSA análisis se dividió en dos partes y un subfaceta, llamado el aspecto faceta técnica de la enseñanza y la formación, la segunda faceta llamado Vínculo entre el campo y la enseñanza específica y su nombre subfaceta aspecto relacional. Del análisis del contenido de las justificaciones de la PCM, llegó a 5 categorías, a saber: Hacer la enseñanza, la faceta negativa, Escuela, Formación y faceta afectiva del profesor. El TALP aporta pruebas de que algunos de estos estudiantes ve la oportunidad de adquirir unos conocimientos en esta área, la formación en un nivel superior, como quieran, simplemente tienen un título universitario para realizar licitación abierta. El PCM nos ha hecho comprender que el contenido representacional en cuestión se configura desde el universo consensual conectado a la profesión y la formación. Por lo tanto, podemos decir que los titulares de licencias con respecto al tema estudiado anclar la representación social de "enseñar" a la imagen de ser un maestro y objetivar la imagen de la profesión

Alternância no uso dos modos indicativo e subjuntivo em orações subordinadas substantivas: uma comparação entre o português do Brasil e o francês do Canadá

The purpose of this work is to analyze the use of the indicative mood, instead of the subjunctive prescribed by the normative grammar, in complement clauses introduced by the conjunction que in Brazilian Portuguese. Contexts of use of the subjunctive according to grammatical prescription, and contexts of fluctuation on the use of that verbal mood were analyzed, in an attempt to investigate what interferes on the choice of the mood by the user of the language. This study is based on North-American Functional Linguistics theoretical perspective, oriented to analyzing language in use, in the light of the principles of grammaticalization and markedness. The results obtained support that the contexts that favor the indicative over the subjunctive are those composed by a complement clause functioning as a direct object the unmarked clause of all complement clauses and by a verb on the main sentence that belongs to the semantic field of low certainty, corresponding to the epistemic sub-mode the unmarked category of the deontic sub-mode. The results indicate that pragmatics and semantics factors influence the language user on the choice of the verbal mood. This research also presents comparative data on the use of the indicative mood in place of the subjunctive in Brazilian Portuguese and Canadian French, aiming to providing suggestions on language teaching

A interpretação dos sintagmas nominais com adjetivos atributivos por alunos de inglês instrumental

This present work has as objective to analyze the interpretation of the syntactic and semantic meaning performed by third graders in the nominal groups (NGs) with attributive adjectives in the English language in a text of the final exam in the ESP (English for Specific Purposes) discipline. The corpus is made up of 30 exams of two classes from a third grade institution of the biomedical area, corresponding to the basic and advanced levels of the second term in 2006. The text has 24 NGs of different lexical content, a total of 27 NGs in the whole text summing up to 810 analyzed occurrences. The analysis is carried out at the morphologic, syntactic and semantic levels using as theoretical background the traditional and functional grammars (QUIRK et al, 1985; CELSE-MURCIA et al, 1998; TUCKER, 1998), in their semantic aspects, the Semantics (FRAWLEY, 1992) and the Cognitive Linguistics (TAYLOR, 2002). We concluded that the main difficulties were due to the lack of vocabulary and to the use of mother tongue strategies instead of using the top-down strategies for reading a text in English to compensate this gap. We also observed that even when the vocabulary was known, there were difficulties in establishing the semantic and syntactic relations between modifier and noun head. We suggested improvements for the teaching of reading English texts at the third grade grounded in the obtained results such as a more comprehensive study of the several different morphologic and syntactic structures of the NGs with premodifiers and their semantic consequences, an approach of the morphologic, syntactic and semantic aspects of the NGs and the use of both top-down and bottom-up strategies when reading a NG in the English language

A relação gramatical objeto direto : implicações para o ensino de língua materna

This paper attempts to investigate the discourse manifestations of the grammatical relation direct object with respect to the syntactic, semantic and pragmatic properties that underlie this element. The research adopts theoretical orientation of the functionalism from North American and Brazilian schools inspired in Givón (1995, 2001), Hopper and Thompson (1980), Chafe (1979), Furtado da Cunha, Oliveira, Martelotta (2003) inter alia. From functionalism, the research uses principles of iconicity, markedness and informativity and it analize categories of transitivity, grounding and animacy. This research is anchored in prototype model (TAYLOR 1995); construction grammar model (GOLDBERG 1996, 2002). Both theoretical orientations share the view that language is a malleable living organism subject to socio-cultural context. Grammar is then the result of created, maintained, and systematized linguistic patterns developed from and used for language use. According to a functional linguistics and cognitivist linguistics verbs are stored in the speakers lexicon in syntactic-semantic frames which are more frequent. These frames carry information concerning obligatory and optional arguments and the semantic roles these arguments take in the clause. The analysis focuses on the semantic type of the verbs and its relationship with the argument encoded as a direct object observing the aspectual nature of verbs. Direct objects are classified according to their morphology (lexical or pronominal noun phrase), semantic role, informational content and animacy. This study discusses pedagogical implications with relation to how the grammatical concepts touched on this paper are treated in school textbooks. The empirical data come from Corpus Discurso & Gramática: a língua falada e escrita na cidade do Natal (FURTADO DA CUNHA, 1998). This corpus is composed of texts that contain spoken and written modalities. These modalities are in turn organized according to different types: personal narratives, retold narrative, description of preferred place, procedural place, procedural description and report on argumentation. The sample data totals 40 texts produced by four language consultants of the last graduation date. The paper shows that the same syntactic structures (formed through Subject-Verb-Object) correspond to different semantic-pragmatic structures in relation to specific communicative purposes even verb is an event, process or state. The argument structure are not aleatory but are related to experience; that is the way humans conceptualize the world and talk about it

A prática de correção textual por professoras de língua portuguesa do ensino médio

Cette recherche analyse les pratiques de correction de textes de l'enseignement du 1, 2 et 3 ème niveau. Nous avons parti de discutions avec les professeurs de Langue Portugaise des troisièmes annèes d‟une école appartenant au enseignement publique, située à la ville d‟Assu RN. L'étude a les postulats théoriques de Cruz (2007), Dellagnelo (1998), Oliveira (2005), Pécora (1999), Ruiz (2001), Serafini (1989), et d‟autres. La méthodologie est de nature qualitative et d‟interpretation, dont le matériel a été constitué à partir des rapports des enseignants professionnels, ainsi que les 92 textes recueillies entre juillet et août 2008. Les dés montrent que la correction se configure comme un travail pratique, qui vise à aider les étudiants à améliorer leur écriture. Les professeurs font la correction d‟une forme mélangée, c'est-à-dire dans le texte apparaissent les corrections orthographiques, lexicales, etc., mais la prédominance de la correction est par rapport aux idées, pour le contenu du texte. Dans ce sens, les professeurs se rendent compte du valeur et de la hiérarchisation des idées discutées par les élèves, les reconnaître comme l'organisation de la sémantique et la séquence du texte. Tous les autres aspects (structurelles, grammaticaux) sont importants, cependant, en général, dans la pratique de correction des études, l‟exposition les idées occupent une place importante. Les marques de correction apparaissent sous la forme de petits billets, qui apprécie également toutes les étapes de l'écriture de texte

A complexidade do ser fictício: a construção da personagem Marcela no romance A ostra e o vento

It is possible to notice that the modern narrative increasingly seeks to invest its characters with a broad and complex nature, away from the well-defined beings of the traditional narrative. Through this work, we aim to make a study of Marcela, a character of the novel A ostra e o vento, by Moacir Costa Lopes, taking into account the way the complexity of the fictitious being is constituted through an analysis of structural, semantic, and thematic elements. We first will bring up a brief theoretical discussion about the character in a novel, and we also will carefully analyze the diagetic universe, presenting the complex path of the character further. Subsequently, we will focus on the structure of the narrative which creates a complex picture of the character, using the technique of crossed points of view as well as the technique of temporal fragmentation. Finally, we will investigate conflicting social relations that portray Marcela s disturbed inner side, as well as the metaphoric symbolic language, which furnishes a number of different representation of this character, impeding the creation of a well-structured coherent character. Studies of scholars such as Antonio Candido, Anatol Rosenfeld, Vitor Manuel de Aguiar e Silva, Fernando Segolin, Gerard Genette, Michel Zéraffa, among others, will guide our analysis

Entre a fé, a obra social e a publicidade: uma análise crítica do discurso da responsabilidade social da Igreja Universal do Reino de Deus

Situated on Applied Linguistics (PENNYCOOK, 1998; MOITA LOPES, 2003, 2006, 2008, 2009), this thesis, which is inscribed in a qualitative-interpretative approach of a critical analysis perspective , lies on the speech of social responsibility and the way like that is employed in seeking for legitimacy and prestige within the neopentecostal brazilian religious field, more specifically of the Universal Church of the Kingdom of God. The general goal of this research is t reflect upon the speech on social responsibility and the rethoric of selfpromotion of the Universal Church through the role of social actors in the making of his her identities, materialized in the newspaper Folha Universal. In order to achieve that, we have conjugated, in this research, social and discursive analysis. On the linguistic-discursive approach, the research is based on the Critical Analysis of Discourse (ACD), specially in Fairclough (2001, 2003, 2006), a proposal that provides theoretical-methodological tools to investigate the language beyond the linguistic structures , that is, the discourse, social practices in which it occurs and more ample structures. Theoretical assumptions were also used of Sistemico-Functional Linguistics(LSF), matching with categories of the Transitivity System of Halliday (1994, 2004), of the forms of representation of social actors in the socioeconomic perspective by Van Leeuwen (1997, 2008) and of the Appraisal system by Martin and White (2005). As we develop the argumentation on thesobre social role of religion in this thesis, we make use of the authors such as Freston (1994), Oro (1997, 2003), Campos (1996, 1999), Mariano (1999), Meneses (2008), among several ones. We have also used a series of concepts and categories coming from the field of communication and marketing on the business social responsability and social marketing . In this area, we take as references the contributions of Bueno (2003), Fossá and Sartoretto (2003) and Zenone (2006). The corpus of the work is framed by news taken at the newspaper Folha Universal, in which are given the social responsibility actions of the church . The timeframe used was on the editions of 2010 thru 2012. Results found at he analysis of the News lead to semantic features of Assessment of Affection, Judgment and Appreciation, many times followed by Gradation, and the Attribution, one of the subsystems of the Attachment, are evidence of positive assessments for the Universal Church and its agents and make up rethorical elements which provide structure for the discourse of the Universal Church at the newspaper Folha Universal consisted of its image (style) of social responsibility . Results show that the most frequente social actors of the discourse are, on one hand, the Universal Church itself and its volunteers, famous (actors, actresses, presenters), politicians and authorities, on the other hand, the population which was helped by the Church social projects . The first group seems to be Always activated, however the second one, most of the time rather passive. These are also represented by assimilation in most of the occurrences, however the other ones by individualization and nomination entitled by honorification, except for the volunteers that are represented either as an individual, or as a group

Identidade, espaço e tempo: negociações de sentido sobre a "gente de rua"

This research examines the street children s identity construction processes. Recently, the research about this population has focused on the socialization processes that organize their everyday, their situations of interaction, the meanings of their social practices, their street experience. The concept of identitary forms gives coherence to the set of these phenomena, articulating them theoretically, in order to describe their life conditions and details of their trajectories. This research utilized an ethnographic approach with a group of 11 street people, 9 of them boys and girls 16-18 years old, during 3 months. It included participant observation, informal and formal interviews, that resulted in young s narratives of lifestory. These narratives were interpreted according to the principles of positioning analysis and the Labovian Analysis model of oral narratives of personal experience. The observation of interaction among the studied group and other groups has showed that their social practices, supported on many particular bodily technologies, recreate space and time of these interactions semantically, as mediation of meaning negotiations among groups. Such meanings transform again the environment of these interactions, disclosing interpretative systems by means of which the groups apprehend this interaction in a particular way. These street children s bodily technologies imply identitary forms based on scarcity and abandonment, paradoxicalally related to their self-concept. The analysis of narratives revealed diversity and complexity in the meanings assembly for their street experience; it showed that the semantic arrangements reconstruct the temporal experience, creating a moral climate for each lifestory, and determining more or less aperture of identitary forms to change. The study concludes that space and time, builders of interaction regimes, produce identitary forms; that the narratives and the social practices of the studied group are sustained upon a master discourse that opposes the meanings of the home and the life in the streets

Uma plataforma de integração de middleware para computação ubíqua

One of the current challenges of Ubiquitous Computing is the development of complex applications, those are more than simple alarms triggered by sensors or simple systems to configure the environment according to user preferences. Those applications are hard to develop since they are composed by services provided by different middleware and it is needed to know the peculiarities of each of them, mainly the communication and context models. This thesis presents OpenCOPI, a platform which integrates various services providers, including context provision middleware. It provides an unified ontology-based context model, as well as an environment that enable easy development of ubiquitous applications via the definition of semantic workflows that contains the abstract description of the application. Those semantic workflows are converted into concrete workflows, called execution plans. An execution plan consists of a workflow instance containing activities that are automated by a set of Web services. OpenCOPI supports the automatic Web service selection and composition, enabling the use of services provided by distinct middleware in an independent and transparent way. Moreover, this platform also supports execution adaptation in case of service failures, user mobility and degradation of services quality. The validation of OpenCOPI is performed through the development of case studies, specifically applications of the oil industry. In addition, this work evaluates the overhead introduced by OpenCOPI and compares it with the provided benefits, and the efficiency of OpenCOPI s selection and adaptation mechanism
