The present study is descriptive, qualitative and exploratory, based on bibliographical sources, in which it was explored how the Classification discipline interacts with Linked Data, focusing on the analysis of Dewey Linked Data. From four catalogs analyzed, referred to in the literature as adhering to Dewey Linked Whzt, only two actually has links in their records redirecting to the system. Despite this, its presence in The Linked Open Data What does base jumping mean in a relationship appears as a positive factor in its dissemination, since it boosts us visibility.
It is concluded that the Classification discipline allows the thematic standardization of information resources, so that there is uniformity in the Web environment and quality retrieval of information, while promoting interoperability between data in the Linked Data context. The standardization of metadata values using classifications optimizes the representation of information and its retrieval in the Web, while also providing the reuse of data.
Resumen: Con la disponibilidad de información en la World Wide Webse facilita su acceso y recuperación por parte de los usuarios, y el conocimiento y las técnicas del campo de la Bibliotecología y Ciencia de la Información BCI se pueden aplicar a este entorno para ayudar con el proceso. A pesar de esto, su presencia en The Linked Open Data Cloud aparece como un factor positivo en su difusión, ya que clasdification su visibilidad.
La estandarización de los valores de metadatos mediante clasificaciones optimiza la representación de la información y su recuperación en la Web, al tiempo que proporciona la reutilización de datos. The passage of information resources what is predator and prey ecology analog to digital supports gives users a greater access to the most varied information in various formats, such as audio, video, text, etc.
Thus, the need for attention to the treatment and organization of information, provided by the skills of Library and Information Science LISbecomes even greater, so that the documents can in fact be accessed and retrieved. At the thematic level of the information resource, the organization can be applied by what is meant by classification of data classification systems, which provides standardized ways for the accomplishment of the activity.
The system studied in this paper is the Dewey Decimal Classification DDCcreated by Melvil Dewey and widely used in libraries for bibliographic organization. From a descriptive, qualitative and exploratory analysis, the present research aimed to analyze the use of Dewey Linked Data by the Online Public Access Catalogs OPACs of libraries and other information centers. The benefits provided by the association between the Semantic Web and Linked Data and the concepts of the area of LIS were also considered.
When discussing about organization byy the informational universe, the discipline of Classification can be of great use. Iis what is meant by classification of data field of LIS, Classification covers the tools and techniques involved in the organization of information resources according to its subjects, facilitating its location and identification Piedade, ; Pombo, Glushko, Annechino, Hemerly and Wang b, p. Still according to Glushko et al. What does dynamic variable mean in programming this sense, classification is biased, since it involves a choice that has to be made to better suit and describe what is meant by classification of data object, such choice being influenced by its purpose, users and the subjectivity of the classifier Glushko et al.
The process of classification follows systems, which are standardized guides to grouping objects according to its similarities and differences in a hierarchical order, supporting information organization by subject and, consequently, information retrieval Glushko et al. When classifying bibliographic resources, bibliographic classiification systems are used, where the DDC system is one of the most widely adopted worldwide Online Computer Library Center, b.
The design of the DDC started inwhen Dewey presented a new scheme for the organization of books in the library of Amherst College, where he worked as an assistant, using symbols notations for the representation of each book Online Computer Library Center, b ; Piedade, Cassification, the DDC is classified as a hierarchical classification system of pure notation Piedade, Each class can be divided into ten more, and so forth.
For further specification, the main classes, or schedules, can be complemented using one of the six subdivision tables. Thus, the DDC enables the classification and organization of the information resources of a collection by applying notations from the schedules or by creating new notations formed from what does investigation mean in medical terms combination of the numbers from the schedules and tables.
However, OCLC offers some features in an open way, such as the introduction of the 23rd edition of the DDC and its glossary, making it easier to datw professionals unfamiliar with the system Online Computer Library Center, d. Another feature available free of charge is the training courses, which consist of modules in PDF format on the DDC tables and construction of notations Online Computer Library Center, d. With the increasing use of machines as the main means of searching for satisfying users' informational needs, there is a growing concern about how this information is introduced into the Web environment and how it can be properly accessed.
So, in the Semantic Web is presented by Berners-Lee, Hendler, and Lassila as a way of improving interaction and communication between man and machine, facilitating the processing of data through the use of semantic technologies and standards. According to Shadbolt, Hall, and Berners-Leep. In order to create and explore these links between related data and information presents in the Web, Berners-Lee defines the Linked Data principles, which are four steps that define a dataset as linkable.
When publishing data, it is important that, just like with any other documents, it is properly described so it can be searched for, accessed and retrieved. In the LIS field the use of metadata is mainly as bibliographic metadata, which according to Rileyp. Alves defines metadata as sets of attributes, more specifically referential data, which represent the informational content cpassification a resource that may be what is meant by classification of data a digital medium or not, used to describe and therefore organize information.
Metadata are formed by elements, values and schemes. They guarantee the structuring of the metadata elements, while also having a markup language that allows the coding of the metadata. By aligning the use of classification systems to the Semantic Web and to semantic technologies, it is possible to optimize and enhance the representation of information in the digital environment, thus favoring the identification of information resources and their retrieval.
The present work is a descriptive, qualitative and exploratory research, which objective is to identify the adoption of the Dewey Linked Data tool in OPACs. The material was collected in the period of and The materials selected were the ones that best corresponded to the theme and problem of the study in question that bj the criteria of the determined time interval and languages.
In order to better understand the applicability of Dewey Linked Data, the OPACs of institutions mentioned in the literature as adherents or partially adherents to the initiative were analyzed. The search tools of the catalogs of each of the information centers were what is meant by classification of data for the presence or absence of a search filter by DDC notation. Some records what is meant by classification of data also verified in order what is meant by classification of data identify the presence are relationship breaks a good idea the Dewey Linked Data notations, both in the presentation of the data in its own Web pages as in the records in semantic formats what is meant by classification of data support Linked Data.
Id, composing the URI is the about section to direct the user to the information about an object. Therefore, RDFa allows documents whaat be enriched from the use of metadata. A set of attributes and parsing rules are defined, but their attributes can contain properties of any RDF vocabularies, allowing an RDFa document to be imported without problems and guaranteeing greater extraction of semantic data World Wide Web Consortium, a. XHTML is a redesign of version 4. It is possible to search for composite notations in Dewey Linked Data, that is, notations formed by combined numbers of the schedules and what is the best product for black hair tables.
WorldCat is an online catalog that allows access to bibliographic records of resources ment the Web, such as books, DVDs, CDs, articles and digital content WorldCat, b. It is possible to observe the presence of a dewey. According to Mitchell and Panzerp. The search can also be performed from the bibliographic record itself, by selecting its notation number, as seen in figure 2.
The British Library catalog allows the search of subjects by notational wuat of the DDC, under which the information resources are classified. When searching for bibliographic records classified in10 results were obtained. It should be noted, however, that all records with the notation and their decimal what is meant by classification of data were also retrieved, even when performing the search by the exact expression Expression exacte. One of the ways to retrieve records more precisely is by selecting the symbol next to the notational number in a bibliographic record, indicated in red in figure 3.
In doing so, a new, more specific notation search is generated by the system, considering both classificationn number and DDC edition. For the notation, it was possible to retrieve 12 bibliographic records using this method. Furthermore, information about DDC notations can be viewed by selecting them in the bibliographic records, presented in two formats: public and Intermarc.
Despite directing from the bibliographic records to information regarding the DDC number, it was not possible to identify a link to the summary in Linked Data of the DDC. The search resulted in 13 bibliographic records, having retrieved all the records which classification is under the notation and derived decimal notation. Repeating the search for the exact notation it was possible to retrieve life best funny quotes bibliographic records.
In red is highlighted the section corresponding what is meant by classification of data the linking of the DDC notation to its corresponding URL in the Linked Data summary, showing that the catalog actually has links to Dewey Linked Data. The Deutsche Nationalbibliothek also provides another resource for subject search based on DDC notations. Compared to the other catalogs analyzed, the Deutsche Nationalbibliothek provides greater possibilities of research and navigation, facilitating the search process.
With the new change of DDC to the digital environment, the next logical step is to use its summary in Linked Data, as its application becomes even more viable, generating a better use of the DDC-related services offered by OCLC. Since the purpose of classification systems is to provide a standardization of what is meant by classification of data thematic representation of information resources, it is possible to say that they act on the mwant level of metadata by providing notational numbers.
In the semantic scope of the Web, the standardization of these values optimizes the retrieval and discovery of the information, also standardizing the relations provided by Linked Data. In this way, it is noted that the Dewey Linked Data satisfies this purpose, allowing their notations to be applied as metadata values in a linkable way. The interface of the Dewey Linked Data could not be evaluated, since its web page is currently, in August ofout of service, which can also be an impediment to its adoption by information centers.
However, its visibility and use can be boosted due to its presence in The Linked Open Data Cloud LOD Clouda diagram of datasets that are published following the Linked Data principles, illustrating the relationships between each dataset, as show in figure 5 McCrae et al. From the analysis of hy literature and results obtained, section 5 presents the reflections on the relationship between Classification and Linked Data principles and their implication to information centers what is meant by classification of data to the area of LIS.
From the research conducted it is possible to state that data representation is essential on the Web, since it is representation that allows finding mexnt retrieving information in the environment. The Classification discipline allows the standardization in the thematic context of the information resource, so that there is uniformity in the Web wgat and quality retrieval what is meant by classification of data information.
Classification is also essential in the Linked Data context, since it facilitates interoperability between data. By using classification systems, in this case the DDC, in the Semantic Web it is possible to repurpose the already established notations as a standard way of representing information resources according to their themes. Combined with Linked Data, the creation of links between related objects is provided, improving information retrieval.
That is possible by reusing the notations as metadata values. Its low rate of adherence might be explained by the fact that the web page is out of service, without a prediction of going back online which also difficulted the present investigation processin addition to not being much discussed by the LIS community. One possibility of countering the situation is to carry out more discussions and researches on Classification in the Semantic Web environment, which can innovate the way libraries operate and relate dats the Web, better contemplating the informational needs what is meant by classification of data a society currently marked by the Web and the technological advances, and thus properly serving the user.
Greater collaboration and dialogue between different communities can bring mutual benefits by providing new elements that contribute to what the other needs, optimizing all areas involved. We suggest as a possible subject of study for datq researches what is the basis of love investigation of different tools, such as vocabularies, applied to the Web, in order to better understand and show the flexibility of instruments developed in the LIS domain.
