BACKGROUND. Bioinformatics is commonly featured as a well assorted list of available web resources. Although diversity of services is positive in general, the proliferation of tools, their dispersion and heterogeneity complicate the integrated exploitation of such data processing capacity. RESULTS. To facilitate the construction of software clients and make integrated use of this variety of tools, we present a modular programmatic application interface (MAPI) that provides the necessary functionality for uniform representation of Web Services metadata descriptors including their management and invocation protocols of the services which they represent. This document describes the main functionality of the framework and how it can be used to facilitate the deployment of new software under a unified structure of bioinformatics Web Services. A notable feature of MAPI is the modular organization of the functionality into different modules associated with specific tasks. This means that only the modules needed for the client have to be installed, and that the module functionality can be extended without the need for re-writing the software client. CONCLUSIONS. The potential utility and versatility of the software library has been demonstrated by the implementation of several currently available clients that cover different aspects of integrated data processing, ranging from service discovery to service invocation with advanced features such as workflows composition and asynchronous services calls to multiple types of Web Services including those registered in repositories (e.g. GRID-based, SOAP, BioMOBY, R-bioconductor, and others).

The international Functional Annotation Of the Mammalian Genomes 4 (FANTOM4) research collaboration set out to better understand the transcriptional network that regulates macrophage differentiation and to uncover novel components of the transcriptome employing a series of high-throughput experiments. The primary and unique technique is cap analysis of gene expression (CAGE), sequencing mRNA 5'-ends with a second-generation sequencer to quantify promoter activities even in the absence of gene annotation. Additional genome-wide experiments complement the setup including short RNA sequencing, microarray gene expression profiling on large-scale perturbation experiments and ChIP-chip for epigenetic marks and transcription factors. All the experiments are performed in a differentiation time course of the THP-1 human leukemic cell line. Furthermore, we performed a large-scale mammalian two-hybrid (M2H) assay between transcription factors and monitored their expression profile across human and mouse tissues with qRT-PCR to address combinatorial effects of regulation by transcription factors. These interdependent data have been analyzed individually and in combination with each other and are published in related but distinct papers. We provide all data together with systematic annotation in an integrated view as resource for the scientific community (http://fantom.gsc.riken.jp/4/). Additionally, we assembled a rich set of derived analysis results including published predicted and validated regulatory interactions. Here we introduce the resource and its update after the initial release.

La infraestructura europea ICOS (Integrated Carbon Observation System), tiene como misión proveer de mediciones de gases de efecto invernadero a largo plazo, lo que ha de permitir estudiar el estado actual y comportamiento futuro del ciclo global del carbono. En este contexto, geomati.co ha desarrollado un portal de búsqueda y descarga de datos que integra las mediciones realizadas en los ámbitos terrestre, marítimo y atmosférico, disciplinas que hasta ahora habían gestionado los datos de forma separada. El portal permite hacer búsquedas por múltiples ámbitos geográficos, por rango temporal, por texto libre o por un subconjunto de magnitudes, realizar vistas previas de los datos, y añadir los conjuntos de datos que se crean interesantes a un “carrito” de descargas. En el momento de realizar la descarga de una colección de datos, se le asignará un identificador universal que permitirá referenciarla en eventuales publicaciones, y repetir su descarga en el futuro (de modo que los experimentos publicados sean reproducibles). El portal se apoya en formatos abiertos de uso común en la comunidad científica, como el formato NetCDF para los datos, y en el perfil ISO de CSW, estándar de catalogación y búsqueda propio del ámbito geoespacial. El portal se ha desarrollado partiendo de componentes de software libre existentes, como Thredds Data Server, GeoNetwork Open Source y GeoExt, y su código y documentación quedarán publicados bajo una licencia libre para hacer posible su reutilización en otros proyecto

In this project a research both in finding predictors via clustering techniques and in reviewing the Data Mining free software is achieved. The research is based in a case of study, from where additionally to the KDD free software used by the scientific community; a new free tool for pre-processing the data is presented. The predictors are intended for the e-learning domain as the data from where these predictors have to be inferred are student qualifications from different e-learning environments. Through our case of study not only clustering algorithms are tested but also additional goals are proposed.

Nowadays, when a user is planning a touristic route is very difficult to find out which are the best places to visit. The user has to choose considering his/her preferences due to the great quantity of information it is possible to find in the web and taking into account it is necessary to do a selection, within small time because there is a limited time to do a trip. In Itiner@ project, we aim to implement Semantic Web technology combined with Geographic Information Systems in order to offer personalized touristic routes around a region based on user preferences and time situation. Using ontologies it is possible to link, structure, share data and obtain the result more suitable for user's preferences and actual situation with less time and more precisely than without ontologies. To achieve these objectives we propose a web page combining a GIS server and a touristic ontology. As a step further, we also study how to extend this technology on mobile devices due to the raising interest and technological progress of these devices and location-based services, which allows the user to have all the route information on the hand when he/she does a touristic trip. We design a little application in order to apply the combination of GIS and Semantic Web in a mobile device.

L'objecte del projecte és estudiar en profunditat els sistemes gestors de bases de dates en l'àmbit de la web semàntica. Aquests sistemes són gestors de bases de dades especialitzats en l'emmagatzematge i tractament de dades semàntiques, tot tenint en compte les peculiaritats d'aquestes. Per tal d'aprofundir en la matèria, el projecte es divideix en dues parts principals. En la primera es recerca l'estat de l'art, fent un estudi comparatiu entre els magatzems semàntics més coneguts en l'actualitat. En la segona part s'estudia en profunditat un d'aquests magatzems (Virtuoso Universal Server).

Introduction: Our goal was to know the web contents and examine the technical information pest control services available to users through their webpages. Method: A total of 70 webpages from biocides services in the province of Málaga (Spain) were analyzed. We used 15 evaluation indicators grouped into 5 parameters relating to data of the service provider; information’s reliability and services; accuracy of content and writing style; technical resources and interaction with the users. As test instruments were used sectoral legislation, official records of products and deliveries, standards and technical guides. Results: Companies showed a remarkable degree of awareness with the implementation and use of new technologies. Aspects negative that they can have an impact on the confidence of users, relating to the reliability of the information and deficiencies associated with the description of the services portfolio and credentials of the companies were identified. The integration and use of collaborative platforms 2.0 was poorly developed and squandered. Discussion: It is possible to improve the trust of users intervening in those aspects that affect the reliability of the information provided on the web.

This paper presents the platform developed in the PANACEA project, a distributed factory that automates the stages involved in the acquisition, production, updating and maintenance of Language Resources required by Machine Translation and other Language Technologies. We adopt a set of tools that have been successfully used in the Bioinformatics field, they are adapted to the needs of our field and used to deploy web services, which can be combined to build more complex processing chains (workflows). This paper describes the platform and its different components (web services, registry, workflows, social network and interoperability). We demonstrate the scalability of the platform by carrying out a set of massive data experiments. Finally, a validation of the platform across a set of required criteria proves its usability for different types of users (non-technical users and providers).

In the past, research in ontology learning from text has mainly focused on entity recognition, taxonomy induction and relation extraction. In this work we approach a challenging research issue: detecting semantic frames from texts and using them to encode web ontologies. We exploit a new generation Natural Language Processing technology for frame detection, and we enrich the frames acquired so far with argument restrictions provided by a super-sense tagger and domain specializations. The results are encoded according to a Linguistic MetaModel, which allows a complete translation of lexical resources and data acquired from text, enabling custom transformations of the enriched frames into modular ontology components.

O propósito da Web Semântica é conseguir uma Web de dados totalmente ligada, isto é, numa perspetiva Linked Open Data. A Web Semântica deve garantir (estabelecendo padrões tecnológicos, vocabulários, linguagens lógicas, etc.) que os conteúdos publicados na Websejam inteligíveis quer por agentes humanos, quer por agentes máquina. Esta dissertação tem como objetivo responder à um problema delimitado, propondo uma solução no quadro da Web Semântica e suas tecnologias. Partindo-se de uma lista de termos em linguagem natural utilizados no Website da ANACOM (Autoridade Nacional de Comunicações), propomos uma organização de acordo com metodologias de construção de ontologias e vocabulários. Inspirámo-nos em duas metodologias, o Ontology Development 101 e o Process and Methodology for Core Vocabularies. O vocabulário controlado resultante, tem como base tecnológica o modelo de organização de conhecimento, recomendado pelo W3C (World Wide Web Consortium), o SKOS (Simple Knowledge Organization System). Trata-sede uma tecnologia standard da W3C desde 2009, utilizada na criação de tesauros,esquemas de classificação, taxonomias, glossários e outros tipos de vocabulários controlados. Como resultado da nossa intervenção, conseguimos organizar e codificar em SKOS, cerca de cinco centenas de termos identificados no Website da ANACOM. Para além da proposta do vocabulário controlado, passámos em revista às tecnologias e teorias que sustentam a temática da Web Semântica.
