Nautical charts are an essential information resource for safe navigation. However, they are not only a useful resource for navigators; According to the International Hydrological Organization (IHO), they essentially fulfill two functions: 1) Maritime navigation, since most hydrographic services have the obligation to provide coverage of the nautical charts of their national waters, in all coastal waters, including major ports and smaller marinas of purely local interest. and 2) as a source of information, since national nautical charts present a detailed configuration of the seabed. Information on the shape of the seabed is required by a diversity of users in addition to navigators; for example, engineers interested in onshore construction, dredging contractors, oceanographers, defense agencies, coastal zone managers, etc. Traditionally, there are three essential elements that play an important role in information retrieval: title, author, and subject access point. Among the latter, one can distinguish indexing by natural language and by controlled vocabularies. The thematic access points, makes it easier for the user to search and retrieve all types of resources that satisfy their information needs. Traditionally in the processing of nautical charts the natural language is used predominantly, motivated by a lack of availability of a controlled vocabulary specific to the área in Spanish. The objective of this work is aimed at establishing the criteria for the construction of a controlled vocabulary in Spanish in the field of nautical charts.

Comprehensive Comparison

Abstract Book search is far from a solved problem. Complex information needs often go beyond bibliographic facts and cover a combination of different aspects, such as specific genres or plot elements, engagement or novelty. Conventional book metadata may not be sufficient to address these kinds of information needs. In this paper, we present a large-scale empirical comparison of the effectiveness of book metadata elements for searching complex information needs. Using a test collection of over 2 million book records and over 330 real-world book search requests, we perform a highly controlled and in-depth analysis of topical metadata, comparing controlled vocabularies with social tags. Tags perform better overall in this setting, but controlled vocabulary terms provide complementary information, which will improve a search. We analyze potential underlying factors that contribute to search performance, such as the relevance aspect(s) mentioned in a request or the type of book. In addition, we investigate the possible causes of search failure. We conclude that neither tags nor controlled vocabularies are wholly suited to handling the complex information needs in book search, which means that different approaches to describe topical information in books are needed.

BACKGROUND The information literacy treatment, which comprises an important part of the process of disease, is one of the aspects of health literacy and this concept has been explored in fewer studies. OBJECTIVE The purpose of the present study is to investigate the state of the components of information literacy treatment in Women cancer patients. METHODS This is an applied, survey-based study. The population consists of 143 Women cancer patients were selected employing a cluster random sampling procedure. Data were collected through a researcher-made questionnaire. The questionnaire includes 37 questions consisting of six categories—medications, treatment methods, nutrition, medical tests, treatment costs, and sport exercise. RESULTS The findings showed that patients had the most information needs in the five components (except sport exercise). In addition to, the most important source of information for patients was the doctor and, of course, some of the other medical staff. Also, all the identified criteria for cancer patients were important in using the information sources for treatment. The problems such as: specialized content, unfamiliarity with the medical terms, the complexity of the treatment process, are very important to the patients. CONCLUSIONS The health professionals play an important role in shortening the interval between the patients` need for information and receiving information. It is recommended for the health authorities to hold free classes in health centers and prepare simple and comprehensible materials in these courses.

Actual Use

The controlled vocabulary versus the free text approach to information retrieval is reviewed from the mid 1960s to the early 1980s. The dominance of the free text approach following the Cranfield tests is increasingly coming into question as a result of tests on existing online data bases and case studies. This is supported by two case studies on the Coffeeline data base. The differences and values of the two approaches are explored considering thesauri as semantic maps. It is suggested that the most appropriate evaluatory technique for indexing languages is to study the actual use made of various techniques in a wide variety of search environments. Such research is becoming more urgent. Economic and other reasons for the scarcity of online thesauri are reviewed and suggestions are made for methods to secure revenue from thesaurus display facilities. Finally, the promising outlook for renewed develop ment of controlled vocabularies with more effective online display techniques is mentioned, although such development must be based on firm research of user behaviour and needs.

The Way

In this article, we present MyrrorBot , a personal digital assistant implementing a natural language interface that allows the users to: (i) access online services, such as music, video, news, and food recommendation s, in a personalized way, by exploiting a strategy for implicit user modeling called holistic user profiling ; (ii) query their own user models, to inspect the features encoded in their profiles and to increase their awareness of the personalization process. Basically, the system allows the users to formulate natural language requests related to their information needs. Such needs are roughly classified in two groups: quantified self-related needs (e.g., Did I sleep enough? Am I extrovert? ) and personalized access to online services (e.g., Play a song I like ). The intent recognition strategy implemented in the platform automatically identifies the intent expressed by the user and forwards the request to specific services and modules that generate an appropriate answer that fulfills the query. In the experimental evaluation, we evaluated both qualitative (users’ acceptance of the system, usability) as well as quantitative (time required to complete basic tasks, effectiveness of the personalization strategy) aspects of the system, and the results showed that MyrrorBot can improve the way people access online services and applications. This leads to a more effective interaction and paves the way for further development of our system.

We developed and reported a standard-free method for beard (including mustache and whiskers) samples that enables us to quantitatively analyze powdered beard samples of extremely small quantity. In order to investigate intake of essential elements and also exposure to toxic elements, daily changes of elemental concentration in the body give us essential information. Firstly, we have measured dependence of elemental concentration in beard, mustache and whiskers on the collecting regions in the face. Then, daily changes of elemental concentration in the body, which reflect daily ingestion of foods and waters, have been estimated by means of quantitative analyses of beard samples. These beard samples were taken from three persons everyday over successive 7, 14 and 33 days, respectively. As a result, some elements show long-term changes and a few toxic elements such as arsenic and lead exhibit changes in a period of a few days. We have also measured daily changes of elemental concentration in urine and beard taken from the same person at the same time every half day over 10 days, and clear correlation of daily changes of the arsenic concentration between urine and beard samples was observed. It is found that the standard-free method is quite effective for beard samples of very small quantities, and that beard analyses are quite suited to studies on daily changes of elemental concentration in the human body in comparison with the other samples depending on the elements.

One of the most important tasks of a librarian is the assignment of appropriate subject(s) to a resource within a library’s collection. The subjects usually belong to a controlled vocabulary that is specifically designed for such a task. The most widely adopted controlled vocabulary across libraries around the world is the Library of Congress Subject Headings (LCSH). However, there seems to be a shifting from traditional LCSH to modern thesauri. In this paper, a methodology is proposed, capable of incorporating thesauri into existing LCSH-based Information Retrieval–IR systems. In order to achieve this, a mapping methodology is proposed capable of providing a common structure consisting of terms belonging to LCSH and/or a thesaurus. The structure is modeled as a Simple Knowledge Organization System (SKOS) ontology, which can be employed by appropriate subject-based IR systems. As a proof of concept, the proposed methodology is applied to the DSpace-based University of Piraeus digital library.

Indian society has been bound by culture and tradition since ancient times. The patriarchal system and the gender stereotypes in the family and society have always showed a preference for the male child. Sons were regarded as a means of social security and women remained under male domination. Due to her subordinated position, she has suffered years of discrimination, exploitation and subjugation. She became the victim of several evils like child marriage, sati, polygamy, Purdah system, female infanticide, forced pregnancy, rape etc. In such incidents/recorded cases surprisingly mother-in-law are also taking active part. This discrimination and violence against women had an effect on the sex ratio in India. The main causes of violence are unequal power-relations, gender discrimination, patriarchy, and economic dependence of women, dowry, low moral values, negative portrayal of women's image in media, no participation in decision-making, gender stereotypes and a negative mindset. In this study about 69.39% of the respondents were married and 4.91% respondents were widow, it is observed that 3.82% of respondents were divorcee. The rest of them 21.85% were unmarried. In this study 50.27% majority of the women need information on education information, followed by information on others respectively 25.68%, agriculture information 22.95%, employment information 15.30%, health care information 11.48%, loan and politics information 9.29%, food nutrition, entertainment information respectively 6.01%, the lowest 3.28% of the respondents needed information on religion. In this study 88% of respondents responded that they were highly satisfied with the source of information, where as 9% of respondents responded that they were partially satisfied, 2.73% of respondents said that the source of information are moderately satisfied.
