In the legal field, it is a fact that large number of documents are processed every day by management companies with purpose extracting data they consider most relevant in order to be stored their own databases. Despite technological advances, many organizations, task examining these usually-extensive documents for just few essential still performed manually people, which is expensive, time-consuming, and subject human errors. Moreover, usually follow several conventions both...

Location-based services have become an increasingly interesting research area in the last two decades. However, many scenarios, dealing with most precise location coordinates is not best solution since people structure world geographic areas instead of coordinates. Since humans work abstractions, and names are way we refer to those introducing semantics definitions becomes natural. For example, users can be interested states vacation resorts may want retrieve state names, exact limits such...

In the latest years, there has been a huge effort to deploy large amounts of data, making it available in form RDF data thanks, among others, Linked Data initiative. this context, using shared ontologies crucial gain interoperability, and be able integrate exploit third party datasets. However, same ontology does not suffice successfully query or external within your own dataset: actual usage vocabulary (e.g., which concepts have instances, properties are actually populated how, etc.) is for...

Abstract The classification of police reports according to the typification criminal act described in them is not an easy task. are written natural language and often present missing, imprecise, or even inconsistent information, lack sufficient details make a clear decision. Focusing on property crimes, aim this work assist judges process by automatically extracting information from producing list possible classifications crimes accompanied degree confidence each them. follows design science...

The Web is experiencing a continuous change that leading to the realization of Semantic Web. Initiatives such as Linked Data have made huge amount structured information publicly available, encouraging rest Internet community tag their resources with it. Unfortunately, interlinked domains and so big handling it efficiently has become really difficult for final users. Thus, we provide them tools search needed in an easy way. In this paper, propose approach users different domain views on...

During the last years, mobile computing has been focus of many research efforts, due mainly to ever-growing use devices. In this context, there is a need manage dynamic data, such as location data or other provided by sensors. As an example, continuous processing location-dependent queries subject thorough research. However, still highly expressive ways formulating queries, augmenting in way systems' answer capabilities. Regarding issue, modeling power Description Logics (DLs) and inferring...

Objective: In an open cross-over study, the effect of two different venoactive drugs was prospectively studied in a series patients with post-thrombotic syndrome. Design: Prospective, study. Patients: Twenty-nine established unilateral deep venous insufficiency at least 12 months duration, and history venography-proven thrombosis affected leg. Interventions: On entering were randomly assigned to receive either Hidrosmina (Venosmil, FAES SA, Spain) 600 mg daily, or...

The syntactic approach of most Web search engines still has the drawback not considering semantics keywords entered by user. So, users usually have to browse many hits looking for information they want. In this paper, we present a system that, given set with well defined semantics, automatically generates formal queries, in query language user's choice, which attempt capture what user had mind when she or he wrote those keywords. uses ontologies and description logics reasoner perform...

Since the birth of Semantic Web, numerous knowledge bases have appeared. The applications that exploit them rely on quality their data through time. In this regard, one main dimensions is conformance to expected usage vocabulary. However, vocabulary (i.e., how classes and properties are actually populated) can vary from base another. Moreover, time, such evolve within a diverge previous practices. Methods been proposed follow evolution by observation changes intentional schema (or ontology);...

Location-Based Services (LBS) are attracting a great interest with the fast expansion of mobile computing nowadays. These services use user location to customize offered information. However, most those designed for specific scenarios and goals implicit knowledge about application context. As consequence, hundreds them available (even same purpose). So, it is difficult users choose suitable service as they in charge knowing/finding which will be interesting them, handle information that such...
