This document describes two metadata enrichment micro-services developed for the LoCloud project: a background link micro-service and a vocabulary matching micro-service. The background link micro-service uses DBpedia Spotlight, a state-of-the-art tool for Named Entity Disambiguation, to automatically link cultural heritage items to Wikipedia pages. The vocabulary matching micro-service links items to relevant concepts from a provided vocabulary. Both micro-services are implemented as REST services and deployed on virtual machines. The services are used in enrichment workflows through the LoCloud Generic Enrichment Service.
A great power point presentation for DBMS Concepts from start to end and with best examples chapter by chapter. Please go though each chapters sequentially for your knowledge.
A very easy going study material for better understanding and concepts of Database Management System!
The document discusses using linked data in Semantic MediaWiki to visualize biological data from multiple sources. It summarizes creating dynamic wiki pages for tens of thousands of gene and disease instances by importing RDF triples and using templates to display the data visually through various charting libraries. Examples of instance pages with interactive charts are provided from the joint Vulcan-Allen Institute Neurowiki project mapping genetic data.
The Data2Semantics project (COMMIT P23) is all about enriching research data, and making it more reusable for future research. Using Linked Data for this task is a fairly obvious step to make (surprise!). However, there are several shortcomings the current practices in publishing Linked Data, that calls for a slightly
different approach which (hopefully) bridges a gap between Web 2.0 and Web 3.0. I will present a proof-of-concept service (Linkitup) that works on top of existing scientific data repositories, and allows individual researchers to enrich their data with additional (linked) metadata.
WebSmatch is a platform for integrating open data from heterogeneous sources (1). It addresses problems with large numbers of data sources in different formats, including many Excel files that are poorly structured (2). WebSmatch crawls, classifies, documents and references data sources, then extracts and structures the data for visualization through APIs (3). It uses machine learning and concept matching to extract metadata from Excel files, including detecting tables, attributes, and concepts (4,5,6,7,10,11). The results are exported in structured formats like DSPL for third party use and visualization (13,14,16). Future work includes automating extraction at scale, clustering documents, and integrating with other tools (
Crosswalks show how to map data elements from one metadata schema to another. They are used to integrate datasets that use different standards. Creating a crosswalk involves harmonizing the schemas, semantically mapping elements, and establishing rules to handle complex mappings. Once the crosswalk is defined, metadata descriptions can be transformed from the source schema to the target schema. However, information may be lost due to differences between the schemas.
Metasearch engines search multiple search engines simultaneously and display the results together. They are useful for getting a quick overview of search results or when individual search engines are not providing relevant results. While metasearch engines provide fast results from multiple sources, they have limitations such as fewer search options and results that rely more on directories than comprehensive web searches. Examples of metasearch engines include Dogpile, Clusty, Mamma, Hotbot, and Ixquick.

Growth of relational model: Interdependence and complementary to big data IJECEIAES
A database management system is a constant application of science that provides a platform for the creation, movement, and use of voluminous data. The area has witnessed a series of developments and technological advancements from its conventional structured database to the recent buzzword, bigdata. This paper aims to provide a complete model of a relational database that is still being widely used because of its well known ACID properties namely, atomicity, consistency, integrity and durability. Specifically, the objective of this paper is to highlight the adoption of relational model approaches by bigdata techniques. Towards addressing the reason for this in corporation, this paper qualitatively studied the advancements done over a while on the relational data model. First, the variations in the data storage layout are illustrated based on the needs of the application. Second, quick data retrieval techniques like indexing, query processing and concurrency control methods are revealed. The paper provides vital insights to appraise the efficiency of the structured database in the unstructured environment, particularly when both consistency and scalability become an issue in the working of the hybrid transactional and analytical database management system.

Open Archives Initiatives For Metadata HarvestingNikesh Narayanan
The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) provides a simple but effective mechanism for metadata harvesting. It allows service providers to aggregate content from data providers to build value-added services. The OAI-PMH uses HTTP and XML to share metadata in any agreed format, with Dublin Core as a baseline. It defines a set of verbs and standards for harvesting metadata from repositories in a consistent way. This interoperability has helped surface resources and build services across independently developed digital libraries.

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

Last decades we opened the way in our institutions to the hybrid library, and the electronic
collection was constituted as a library quality indicator
is not enough a good collection of
electronic resources, from now on the
evaluation will also fix its attention in
the digital portal, the success of the
information architecture (AI) and its
functionalities
3. This takes us to consider
a specific human team is needed, with a group of deep knowledge and in permanent
bring up to date.
the Library should have a budgetary departure, in order to maintain chapter like in that
of investments, for the maintenance of the portal,
the librarians should confront the administration of the contents in the portal as a new
activity area
Today's library would be that considers the best form of applying the technology to
satisfy the necessities and expectations of the user(1)

5. 3. Material and Methods
To carry out the study, we considered three parameters:
the available literature on those “Library Portals” and metasearchers
the information given by the suppliers of Library Management Systems
(LMS) and tabulated through an insole of 81 items contained in 13
areas(3)
the results and the evaluation of the same ones through a series of
equations of searches replied in each metasearcher

6. 4. What is the Library Portals?
they are tools constituted by two differentiated components: the user's interface and that of the
librarian.
•The first one allows to present them resources of the library in a structured way and its offers
search tools and recovery of the information in the whole collection.
•With second tool, the librarians describe and structure the contents (electronic review,
databases, e-books, opacs, etc.) that will be shown in the user's interface.
It is necessary to differ among “library portals” and mere traversals searchers
since it usually confuses yourself. A “library portal” it is characterized to prepare:
•A administration module of electronic resources so much at cataloguing level as
of diffusion
•A module of user administration and access licenses to the electronic resources
•A metasearcher
•Environments personalized for the users
•A module of use statistical
7. 5. What is a metasearcher?
It is a system that allows the unified access (unique Interface) to multiple systems and resources
of information (databases, OPAC's, Gateways, etc..). It carries out a search simultaneously in a
selection of databases and electronic resources.
When receiving an application, the system metasearcher determines which systems possess in its
base of knowledge and which are appropriate to interrogate and to obtain information. It looks for,
it organizes, it structures and it sends the information to the user that carried out this search(4).
they should look for and to recover information of a great systems variety(5;6) and metadatos models
that include:
• Open norms (Z39.50, open Norms, OAI-PMH, SRW/SRU, http, MARC, DOI, SQL, EAD, TEI, XML,
Dublin Core, etc..)
• Methodologies Owners.
• System of local Information

28. 7. Comparative starting from a practical supposition
To conclude, we outlined a practical series of 10 suppositions that replied in the five
metasearchers (MetaLib, ZPortal, MAP, SearchSolver, Sirsi), to evaluate the behavior of each one
of them.
Two databases were selected from the meta finding resources:
• MEDLINE
• ISI PROCEEDINGS
and a portal of electronic magazines:
• SCIENCE DIRECT
The searches are very closed, that is to say, very sensitive and precise, for what you/they throw
small results that we browsed, to try to evaluate the relevance of the same ones and to
determine the quality and exahustiveness of the metasearchers.
Of all the thrown searches, we will illustrate this final phase of the comparative one with the
following example:
29. Practical supposition
A clinical has a patient, 24 year-old woman. A hairdresser that presents numerous episodes of different migraine
intensity from the 14 years, beginning retroocular, unilateral localization (varying in the different crises), pulsatil,
associated to nauseate and vomits, of 24-48 hours of duration. To alleviate the pain she uses paracetamol, but the
answer to the same one it is scarce, improving fundamentally with dream and rest.
After normal physical and neurological exploration. Analytic and cranial TC without discoveries worthy of mention,
he take the decision to put a treatment prophylaxis migraine, but he has doubts between the use of the flunarizine
or a beta blockers (propanolol).
For he requests it articles that help you in their clinical decision, where results of preventive treatments are
evaluated with the employment of the two active principles.
Search equation:
Migraine AND (flunarizine AND betablockers)
The results of the behavior of each one of them, with the same search equation are reflected in the following
chart.

31. Results
To bird view, all respond well. Above 80% of satisfaction. In a resource Z39.50 (Medline), the metasearchers
implements the search equation appropriately and they coincide in 100% with the results that it throws the
native source with the same interrogation syntax.
The differences begin to be evident in those resources where it is necessary the use of a gateway. The design
of the same one and the characteristics of the operation of the motor of search of each metasearcher, they
determine the quality of the obtained results.
They notably highlight low this shade, MetaLib, MAP and Sirsi, to the being the only ones which return
registrations in the resources ISI Proceedings and Science Direct.
It is necessary to highlight that MAP, not only returns 4 references of Science Direct of the table 1, but rather
it also recovers, 6 references from the same portal of magazines:

34. 8. Conclusions
The great quantity of information and the notable increase of databases ends in the necessity of
carrying out simultaneous consultations with a single strategy (query). Of this necessity those
denominated arise “metasearchers”
The results of the search can be satisfactory or not so much. The metasearchers offers very
different results before oneself initial question; this fact demonstrates the little exhaustive(8) and it
shows the derived problems of the shortage of linguistic control
At the moment one pleads for the incorporation of tools of linguistic analysis and terminological
control in the metasearchers, so that it is possible to make a less bound recovery to the
comparison of character chains and more linked to the comparison of concepts
The metasearchers allows to carry out a first exploratión(9) on a topic and to locate the information
of available interest quickly in different databases
(8) Murray R. La National Library for Health del Reino Unido usa un nuevo motor de búsqueda. El profesional de la
información 2006;15(1):49-52.
(9) Metafind. ESADE 2008 Consult 02-02-08. Available from: http://www.esade.edu/biblio/metafindabout.html
35. It will be useful when:
•I don't know in what database to begin to look for
•I want to have a panoramic of the different available types of information
•I want to determine what database it contains more information on a topic
•I want to make a quick and simple search
•I want to make sure of not forgetting any possible resource of interest
•I want to find an article that I don't remember in what database it is available
It is necessary to keep in mind that, depending on the objective of our search, the metasearchers cannot
be the best option because:
•It doesn't look for in all the available resources (only in a selection)
•It cannot offer the same prestations(10) of advanced search that the databases, since it doesn't seek to
substitute the sophisticated search that can be carried out in each one of the native sources
•The search for subject(11) in many cases it is not sufficiently precise(8;9) (it cannot use the thesauruses
of each database)

36. They should not be used as tool for the investigation in depth. To obtain the best result the most
advisable thing it is to look for in the different databases for separate, the sophisticated search
options that they offer taking advantage.
The handling and control of the existent digital information at the present time, it has generated new
challenges and problems(12) that require to be treated and solved:
Quality and relevancy in the recovery of information. the initiative of files open search to create a
great system of universal scientific knowledge, with the meta date of all the existent academic
information.
Editorial vs open access. He concentrates on the facilities for the diffusion and the accessibility of
the scientific information through Internet. The access initiative open of Budapest (Budapest Open
Access Initiative), it is the first link that looks for to liberate all the contents and to leave them you

Interaction among systems of information. The metasearchers should of to be compatible in a great

37. Of the five evaluated metasearchers, Metalib next to Sirsi, seems a good option. They highlight the
clarity of their interface, the relevance and exahustiveness of their results and the possibilities of
handlings of these. Map, is the third better option. ZPortal and Search Solver stays above the
acceptable minima for a metasearcher
Anything they serve the interoperability, the meta data, the metasearchers, the agents of
connections, the technology able to summarize, of index and of processing natural language, if
there is not quality in the information
It is not enough with “everything” is accessible, but rather it is necessary that it is accessible “all
that I need and only that” in a certain moment. One can say that one of the big impediments of the
OA (Open Access) it will be the overabundance of information, and he leaves in detriment of the
metasearchers.
To offer scientific information doesn't only consists on giving open access, but in giving pertinent
open access (pertinent open access, POA)
Editors and suppliers of information need to be but informed on the implications of the libraries in
the library portals, to evolve all together and to obtain metasearchers but precise: this is the great
challenge, don't they seem…?
