Pełny tekst źródłaThe goal of this work is, through the study of many technologies, to develop the prototype of a tool able to offer support to the user in query formulation to the MEDLINE (Medical Literature Analysis and Retrieval System On Line). The MEDLINE is a bibliographical information retrieval system in the biomedicine area developed by National Library of Medicine. It is a tool whose usefulness has been amplifyed in this area by the increase of literature utilization, eletronically available, by health care profissionals. People, in general, look for information and are interested in finding it exactly like their expectations, in an agile way and using every single information source available. With this purpouse the first Information Retrieval System (IRS ) emerged, where in a simplifyed way, a user defines a query, that expresses an information necessity and, one step ahead, the system processes it and returns to the user answers from the query. Most of the users think is difficult to represent their information necessity in order to be succesful in searching an IRS. The terms that the user selects to compose the query are not always the same that the system recognizes. In order to be successfull in the definition of the terms that will compose his/her query is advisable that the user know the terminology that was employed in the indexing process of the wanted items or that he/she can have an intermediary person who knows about it. In many situations where no one of these possibilities can be true, resources that make a successfull query possible will be needed. This work, firstly, presents a general study on IRS focusing all the process involved and related to the storage, organization and retrieval. Lately, aspects related to the medical classifications and vocabulary are emphasized, which will be usefull for a largest comprehension of the difficulties found by users during interaction with a system like this. And, finally, the prototype of the Query Formulation System to MEDLINE is presented, as well as its components and funcionalities. The Query Formulation System to MEDLINE was developed with the intention of allowing the user to use any term in the formulation of a query to the MEDLINE. It allows the integration of different medical terminologies originated from classifications and vocabulary available in Portuguese language and in use today. This approach permits the creation of a more complete biomedical terminology in which each term maintains relationships that describe its semantic.

The approach described in this thesis provides a comparison of the verbalizations for both natural language and web query for the same information need by the same user. For this, we used data collected (i.e. users' complaints in natural language and web queries) through a search engine dedicated to economic reports in French over 5 consecutive years totaling a corpus of 1398 natural language requests and 3427 web queries. Then, we compared the expression of the information need and highlighted the contributions in terms of information and clarification, the use of either language used

Information search is a common yet important task in everyday work and life. It remains a challenging design issue how to help users search for information or things they don’t necessarily know how to express with words. Also, even when people know how to express, the cognitive cost required to retrieve the concepts and formulate the queries can be excessive. In this paper, we present Click-Search, a search user interface that allows people to indicate their search intents by merely selecting and cropping segments of image contents. The system automatically converts selected image segments to keywords based on known associations between image pixels and semantic labels created by prior crowdsourced image tagging. Through a user study, we found that Click-Search can support a range of searching activities effectively. We discuss the implications of the new approach of searching through interactions with images.

Pełny tekst źródłaO estudo da relação entre o conhecimento que os professores têm sobre informática, a utilização que fazem do computador na sala de aula e a forma como encaram as opções metodológicas que proporcionem o sucesso do ensinoaprendizagem, foi o objectivo desta dissertação. Neste sentido, procurou-se saber: (1) a relação entre a experiência profissional e o momento em que os professores das diversas disciplinas, se sentiram à vontade na utilização dos computadores; (2) quais as actividades mais utilizadas em cada nível de ensino; (3) quantas aulas são utilizadas para cada software; (4) como cada área de ensino utiliza determinado software e quais os mais utilizados; (5) quais os objectivos que os professores de cada área de ensino pretendem atingir quando utilizam os computadores e quais os mais utilizados; (6) quais os objectivos que os professores têm quando utilizam um determinado software e quais os mais utilizados. A metodologia adoptada foi do tipo quantitativo, e utilizou-se um inquérito para recolha de dados. O estudo realizado envolveu todas as escolas secundárias dos concelhos de Lisboa, Oeiras, Cascais, Amadora, Sintra, Odivelas e Loures, num total de 17 escolas. A população foi constituída por professores do ensino secundário das 17 escolas seleccionadas, das seguintes áreas disciplinares: Português, Matemática, Inglês, Biologia e Geologia, Física e Química, Geometria Descritiva, História, Geografia, e Economia. Em cada escola foi pedida a colaboração a três professores de cada área disciplinar, correspondendo a um total de 27 professores. O número de professores envolvidos no estudo foi de 459. Concluiu-se que os professores com menos anos de serviço e mais jovens adquirem conhecimentos de utilização de computadores mais cedo, ainda no ensino secundário ou enquanto estudantes universitários, e são os que mais o utilizam. A grande maioria dos professores sentiu-se à vontade na utilização dos computadores recentemente. Quando utilizam os computadores em actividades na sala de aula, aproximadamente 63% dos professores pedem aos alunos para trabalharem individualmente ou para colaborarem em actividades de projecto. Os três softwares mais utilizados pelos professores são: Autoria Multimédia (25,4%), WWW Browser e Simulação/Exploração (19%). O software específico é utilizado por 32,3% dos professores de Matemática. Os três principais objectivos quando os professores utilizam os computadores ou um software na actividade lectiva, são: melhorar a aprendizagem, melhorar a compreensão, pesquisa de informações e ideias. O estudo sugere que os professores utilizam os computadores em actividades extra-curriculares e que a grande maioria não utiliza os computadores em actividades curriculares. Sugere também a existência de um défice entre os conhecimentos manifestados e como estes são utilizados na sala de aula. Sugere ainda, que as principais causas do insucesso das tecnologias nas escolas são: a falta de equipamento informático; a insegurança dos professores na utilização das tecnologias; o software inadaptável às actividades curriculares; a falta de formação dos professores em software específico da disciplina que leccionam.
L’étude du rapport entre les connaissances que les professeurs ont sur l’informatique, l’utilisation de l’ordinateur dans la salle de classe et la façon dont ils envisagent les options méthodologiques facilitant la réussite scolaire a été l’objectif de cette dissertation. Dans ce sens, on a cherché à savoir: (1) le rapport entre l’expérience professionnelle et le moment où les professeurs des différentes matières scolaires se sont sentis à l’aise dans l’utilisation des ordinateurs; (2) les activités les plus pratiquées dans chaque degré d’enseignement; (3) le nombre de cours utilisés pour chaque logiciel; (4) comment chaque domaine d’enseignement utilise un certain type de logiciel et ceux qui sont les plus utilisés; (5) les objectifs que chaque domaine d’enseignement prétend atteindre en utilisant les ordinateurs et quels ordinateurs sont utilisés; (6) les objectifs des professeurs quand ils utilisent un déterminé logiciel et ceux qui sont les plus utilisés. La méthodologie adoptée a été de type quantitatif et pour le recueil de données une enquête a été utilisée. L’étude réalisée a concerné toutes les écoles secondaires dês municipalités de Oeiras, Cascais, Amadora, Sintra, Odivelas et Loures, dans un total de 17 écoles. Cette étude s’est dirigée aux professeurs de l’enseignement secondaire des 17 écoles sélectionnées et des matières scolaires suivantes: Portugais, Mathématiques, Anglais, Biologie et Géologie, Physicochimie, Géométrie Descriptive, Histoire, Géographie et Économie. Dans chaque école, on a demandé la collaboration à trois professeurs de chaque matière, ce qui correspond à un total de 27 professeurs. Le nombre total de professeurs concernés par l’enquête a été de 459. On a conclu que les professeurs avec moins d’ancienneté et plus jeunes, acquièrent des connaissances dans l’utilisation des ordinateurs plus tôt lorqu’ils sont encore dans l’enseignement secondaire ou universitaire et ce sont eux qui utilisent le plus les ordinateurs. La grande majorité des professeurs s’est sentie à l’aise dans l’utilisation des ordinateurs récemment. Quand ils utilisent les ordinateurs dans des activités en salle de classe, à peu près 63% des professeurs demandent à leurs élèves de travailler individuellement ou de participer dans d’activités des projets. Les trios logiciels les plus utilisés par les professeurs sont: Applications Multimédia (25,4%), WWW Browser et Simulation/Exploitation (19%). Le logiciel didacticiel est utilisé par 32,3% des professeurs de Mathématiques. Quand ils utilisent les ordinateurs ou unlogiciel en salle de classe les trois principaux objectifs des professeurs sont: faciliter l’apprentissage, faciliter la compréhension, recherche d’informations et d’idées. L’étude suggère que les professeurs utilisent les ordinateurs en activités extrascolaires et la grande majorité ne les utilise pas en activités scolaires. Cette étude suggère aussi l’existence d’un déficit entre les connaissances manifestées et la façon dont celles-ci sont utilisées en classe. Il y est aussi suggéré que les principales causes de l’échec des technologies dans les écoles sont: le manque d’équipement informatique ; le manque d’assurance des professeurs dans l’utilisation des technologies; les logiciels inadaptés aux activités scolaires; le manque de formation des professeurs noté dans dês stages pédagogiques à propos de logiciels didacticiels de la matière qu’ils enseignent
The aim of this essay was studying the relationship between the knowledge teachers have of computing, the use they make of the computer in the classroom and the way they face the methodological options that allow the success of the teaching-learning process. To do it, we tried to know (1) the relationship between the teaching experience and the moment teachers felt comfortable with using computers; (2) which activities are more used in each school level; (3) how many classes are used for each software; (4) how each area of teaching uses a given software and which ones are more used; (5) which are the goals each area of teaching is trying to achieve when using computers and which are more used; (6) which goals teachers have when using a certain software and which are the more used. We adopted a quantitative methodology and we used an enquiry to obtain the data. The study took place in the secondary schools of the areas of Lisbon, Oeiras, Cascais, Amadora, Sintra, Odivelas and Loures totalling 17 schools. The population was constituted by teachers of the secondary level from the 17 selected schools and teaching different subjects: Portuguese, Mathematics, English, Biology and Geology, Physics and Chemistry, Geometry, History, Geography and Economics. We asked for the cooperation of three teachers from each area of teaching in a total of 27 teachers. The number of teachers taking part in the study was 459. We concluded that younger teachers and with less teaching experience acquire knowledge on how to use computers sooner in their lives, some while they are still in secondary school or while at university. These teachers are the ones who use computers the most. Most teachers feel comfortable with using computers recently. When using computers in classroom activities, around 63% of the teachers ask their students to work individually or to cooperate in projects activity. Three different types of software, Authoring Multimedia (25,4%), WWW Browser and Simulations/Exploratory (19%), are the most used by teachers. 32,3% of Mathematics teachers use specific software. When using computers or software in classroom activities the three main goals of teachers are: improving the process of learning, improving the process of understanding, researching for information and ideas. The study suggests that teachers use computers in extra curricular activities and most of them do not use the computers in curricular activities. It also suggests a deficit between the knowledge teachers have and the way this knowledge is used in the classroom. Finally it suggests that the main causes for the lack of success in using technologies in the classroom are: lack of computing equipment; teachers feeling insecure on how to use computing technology; software not adaptable to curricular activities; not enough teacher training activities on specific software for the subject they teach
