Definition and Applications:
The main goal of the Semantic Web is promoting the evolution of the current
Web. This allows users to find, share and combine information more easily.
People are able to use the Web to carry out tasks such as finding the Estonian
translation for "twelve months", find the lowest price for a DVD... However, the
machines can not perform all these tasks without human direction because web
pages are designed to be read by people, not machines. Is a vision of
information that can be easily interpreted by machines, so machines can
perform more tedious work involved in finding, combining and processing the
information on the web.
Some of the Semantic Web applications are:

Freebase aims to "open data silos and the connections between them,"
says founder Danny Hillis at the Web 2.0 Summit. Freebase comprises a
database that is open and contains an API and all kinds of data therein.
Powerset is an engine natural language search. Thanks to this engine
are "semantic connections", which help the semantic database. The aim
is that the meaning and automatically extracts knowledge from
Powerset.
Twine automatically learns about you and your interests as you
populate it with content - a "Semantic Graph". When you put in new
data, Twine picks out and tags convinced content with semantic tags e.g. the name of a person.
AdaptiveBlue recently launched a new version of their SmartLinks
product, which permits web site publishers to complement semantically
charged links to their site.
Hakia try and provide 'meaningful' search effects. Hakia tries to study
the concept of a search query, in particular by doing sentence analysis.
Hakia has two main technologies: QDEX Infrastructure and
SemanticRank Algorithm.
Talis platform is kind of a mix between Web 2.0 and the Semantic Web,
in that it allows developers to construct apps that allow for sharing,
remixing and re-using data.
TrueKnowledge combines natural language analysis, an internal
knowledge base and external databases to offer immediate answers to
various questions.
Tripit is an app that manages your travel planning. With TripIt, you
forward incoming bookings to plans@tripit.com and the system manages
the rest.

Article’s Summary from the European Journal for the Informatics
Professionals 2005:
The article written by Luis Sánchez-Fernández and Norberto Fernández-García
talks about fundamentals and a brief state of the art in a context of the
semantic web. This article reflects a general vision of the semantic web given
some of the problems facing the web today is to find a possible solution. That is
why we propose a web evolution in existence. On the other hand, describes the
basic components of the semantic web.
The publication entitled "Leveraging Metadata Creation by Semantic Web
annotation" whose writing is Siegfried Handschuh explained that the web
semantic has made various contributions as design a complete annotation
framework pioneered minimizing the complexity of semantic annotation by the
scorer. The framework consists of a complete set of modules including
inference services, caterpillars, document management system, the ontology
guidance / fact browser and document editors / readers.
Searching for information retrieval on the semantic has been one of the
motivations of the Semantic Web since it was created. There is a model for
exploitation of ontology-based KBs (knowledge bases) to improve search. The
main objective of this paper is focused on an evolution of the classic vector
model, where keyword-based indices are replaced by an ontology-based KB,
and a semi-automatic document annotation and weighting procedure is the
equivalent of keyword extraction and indexing process. Here we demonstrate
that we can develop a consistent classification algorithm on this basis,
producing measurable improvements regarding the search by keyword, subject
to quality and critical mass of metadata.
According to Harold Boley, we can say that this publication reflects some of the
problems in the design of "Functional RuleMI": The existence of certain
restrictions on attribute values of our attributes can not be done with the DTD.
On the other hand, are difficult to comply with XSD (XML Schema Definition).
However, as focused semantics tool are required for future validation attributes
such as to ensure that a rule base is laminated.
The article “Towards Semantic Desktop Wikis” publicated by Malte Kiesel and
Leo Sauermann, talks about the Semantic Desktop that is about establishing a
network of associations between your sources of information. Some examples
are text documents, web bookmarks, and calendar entries. A wiki has an
underlying model of the knowledge described in its pages.

The authors Bojars, Breslin, Harth and Decker published an article which
summarizes the combination of existing vocabularies terms with new terms are
necessary to describe relations between concepts in the field of community
sites online. Semantically-Interlinked Online Communities Project (SIOC) is a
semantic web technology that provides methods for interconnecting discussion
methods such as blogs, mailing lists to each other.
This paper presents and evaluates the application of a semantic search engine
to get better access to the information content of the Institute: instead of
retrieving documents based on user queries of keywords, the system accepts
language queries natural and returns answers rather than links to documents.
The topics discussed include ontology construction, automatic ontology
population, semantic access through and a natural language interface.
However, there are several things that need improvement, such as generating
an automatic link, a more flexible mechanism for creating queries, an
automated process to generate complete archives of linguistic resources
synonyms...
The article “Semantic Search in Digital Image Archives: A Case Study” is about
a commercial project that applies the concepts presented by the semantic web
to improve the search of images on a web page. Specifically talks about
improving the search for the existence selling pictures over the Internet. The
specific problem concerns sample type semiautomatic techniques for the
creation of thesauri and standardizing image descriptors previous series of
labels that show free keywords with partial morphological expansion. The main
reason for carrying out this project is focused on improving customer access to
a collection of over two million photographs.
The publication entitled “Configuring e-Government Services Using Ontologies”
summarized the highlights a new application of semantic technologies in the
domain of e-Government is the use of semantics to achieve consistent support
configuration and change management of government services electronically.
The contribution of the use of ontologies in the configuration of e-Government
services grouped the ability to perform consistency checks.

a modernization of the educational model that can be replicated by any public
or private entity and thus achieve improved educational development.
