Interoperability and Technology for a Language Resources Factory

This document describes some of the technological aspects of a project devoted to the creation of a factory for language resources. The project’s objectives are explained, as well as the idea to create a distributed infrastructure of web services. This document focuses on two main topics of the factory: (1) the technological approaches chosen to develop the factory, i.e. software, protocols, servers, etc. (2) and Interoperability as the main challenge is to permit different NLP tools work together in the factory. This document explains why XCES and GrAF are chosen as the main formats used for the linguistic data exchange.

Language Resources Factory: case study on the acquisition of Translation Memories

This paper demonstrates a novel distributed architecture to facilitate the acquisition of Language Resources. We build a factory that automates the stages involved in the acquisition, production, updating and maintenance of these resources. The factory is designed as a platform where functionalities are deployed as web services, which can be combined in complex acquisition chains using workflows. We show a case study, which acquires a Translation Memory for a given pair of languages and a domain using web services for crawling, sentence alignment and conversion to TMX.

Diseño e implementación de una Web dinámica como herramienta para el control de obras en base al coste del proceso de construcción

En la actualidad estamos sufriendo una situación de crisis económica de dimensiones desproporcionadas e inusuales, la cual está obligando a todas las empresas a globalizar en mayor medida el ámbito de actuación de sus negocios, por lo que muchas empresas que trabajaban exclusivamente en el ámbito local o nacional han tenido que expandirse hacia el exterior. Este hecho, añadido a la fortísima competencia existente en el mercado, obligará a todas estas empresas a tener que controlar en mayor medida la actividad productiva, y a hacerlo utilizando tecnologías que faciliten el flujo de la información dentro de la empresa, hagan que la distancia no sea un problema para la transmisión de esa información, y con las que todos los usuarios manejen los mismos datos. El sector de la construcción es uno de los más castigados por la citada crisis, y probablemente uno de los más retrasados en lo que respecta a utilización de Tecnologías de la Información y la Comunicación. El objetivo principal de este trabajo es el diseño e implementación de una web dinámica como herramienta para medir la eficiencia en el control de la actividad productiva de una empresa constructora. La manera de medir esta eficiencia será mediante la comparación mensual de los costes previstos para las diferentes obras que deba ejecutar la empresa (los cuales podemos llamar estándar) y los que se vayan produciendo realmente. La herramienta diseñada podría ir aumentando su utilidad si, añadiendo módulos mediante la ampliación de la base de datos y diseñando las pertinentes nuevas páginas web para el sitio, se usa también para otros menesteres además del control de la actividad productiva por comparación entre costes previstos y reales. Es decir, que se podría llegar a gestionar la información de todas las actividades de la empresa (compras, recursos humanos, contabilidad, gestión de calidad, etc.). Por lo tanto, una web dinámica como la expuesta en el trabajo podría servir como semilla para el desarrollo de un ERP (Enterprise Resource Planning).

From institutional repositories to personal collections of learning resources

Institutional digital repositories are a basic piece to provide preservation and reutilization of learning resources. However, their creation and maintenance is usually performed following a top-down approach, causing limitations in the search and reutilization of learning resources. In order to avoid this problem we propose to use web 2.0 functionalities. In this paper we present how tagging can be used to enhance the search and reusability functionalities of institutional learning repositories as well as promoting their usage. The paper also describes the evaluation process that was performed in a pilot experience involving open educational resources.

Analyzing hidden semantics in social bookmarking of open educational resources

Web 2.0 services such as social bookmarking allow users to manage and share the links they find interesting, adding their own tags for describingthem. This is especially interesting in the field of open educational resources, asdelicious is a simple way to bridge the institutional point of view (i.e. learningobject repositories) with the individual one (i.e. personal collections), thuspromoting the discovering and sharing of such resources by other users. In this paper we propose a methodology for analyzing such tags in order to discover hidden semantics (i.e. taxonomies and vocabularies) that can be used toimprove descriptions of learning objects and make learning object repositories more visible and discoverable. We propose the use of a simple statistical analysis tool such as principal component analysis to discover which tags createclusters that can be semantically interpreted. We will compare the obtained results with a collection of resources related to open educational resources, in order to better understand the real needs of people searching for open educational resources.

Aerodynamical instability of web

Diplomityön tavoitteena oli tutkia miten ilman turbulenttisuus vaikuttaa tasaisesti liikkuvan rainan tilaan. Yhtenä sovelluskohteena teollisuudessa voidaan mainita esimerkiksi leiju-kuivain. Tiedetään, että konenopeuksien kasvu ja siitä johtuva ilmavirran nopeuden kasvu aiheuttaa voimavaikutuksia rainaan ja voi aiheuttaa lepatusta. Lepatus johtaa dynaamiseen epästabiilisuuteen, joka voidaan havaita, kun lineaarinen systeemi tulee epävakaaksi ja joh-taa epälineaariseen, rajoitettuun värähtelyyn. Lepatus huonontaa tuotteiden laatua ja voi johtaa ratakatkoihin. Työssä on esitetty tietoa ilman ja rainan vuorovaikutuksesta, jota hyödyntämällä voidaan kehittää yksinkertaistettu malli, jonka avulla liikkuvaa rainaa voidaan simuloida kuivaimes-sa. Kaasufaasin virtausyhtälöt on ratkaistu eri turbulenttimalleja käyttäen. Myös viskoelas-tisen rainan muodonmuutosta on tarkasteltu. Koska rainalle ei ole kirjallisuudesta saatavilla tarkkoja fysikaalisia ja mekaanisia arvoja, näitä ominaisuuksia testattiin eri arvoilla, jotta rainan käyttäytymistä jännityksen alaisena voidaan tarkastella. Näiden ominaisuuksien tun-teminen on ensiarvoisen tärkeää määritettäessä rainan aeroviskoelastista käyttäytymistä. Virtaussimulointi on kallista ja aikaa vievää. Tämä tarkoittaa uusien tutkimusmenetelmien omaksumista. Tässä työssä vaihtoehtoisena lähestymistapana on esitetty yksinkertaistettu malli, joka sisältää ilman ja rainan vuorovaikutusta kuvaavat ominaisuudet. Mallin avulla saadaan tietoa epälineaarisuuden ja turbulenssin vaikutuksesta sekä monimutkaisesta yh-teydestä stabiilisuuden ja ulkoisesti aikaansaadun värähtelyn sekä itse aiheutetun värähtelyn välillä. Työn lopussa on esitetty havainnollinen esimerkki, jolla voidaan kuvata olosuhteita, jossa rainan tasainen liike muuttuu epävakaaksi. Kun turbulenttisuudesta johtuva painevaih-telu ylittää tietyn rajan, rainan värähtely kasvaa muuttuen satunnaisesta järjestäytyneeksi. Saaduttulokset osoittavat, että turbulenttisuudella on suuri vaikutus eikä sitä voi jättää huomioimatta. Myös rainan viskoelastiset ominaisuudet tulee huomioida, jotta rainan käyt-täytymistä voidaan kuvata tarkasti.

Web 2.0 en la docencia universitaria: aprendizaje colaborativo a través de la tecnología

El concepto web 2.0 se utiliza para denominar a un conjunto de aplicaciones que están siempre en evolución de acuerdo a los requerimientos que los usuarios van realizando. En la red podemos encontrar muchas herramientas desarrolladas en la línea de la web 2.0: blogs, wikis, herramientas para compartir marcadores, para compartir archivos, etc. Consideramos que el sistema educativo no puede estar al margen de esta evolución tecnológica y necesita adaptarse a todos los niveles. Las universidades también se encuentran en la necesidad de adecuarse a estos nuevos tiempos, y cada vez encontramos más experiencias formativas de trabajo colaborativo en red para favorecer el aprendizaje de los estudiantes. El trabajo que presentamos es un análisis de herramientas web 2.0 y de una recopilación de buenas prácticas docentes universitarias de desarrollo de metodologías colaborativas utilizando las TIC. Además, ofrecemos recomendaciones del uso de estas herramientas en los procesos de enseñanza y aprendizaje universitario.

Customer driven business model – connecting customer value to firm resources in ICT value networks

The objective of this thesis is to provide a business model framework that connects customer value to firm resources and explains the change logic of the business model. Strategic supply management and especially dynamic value network management as its scope, the dissertation is based on basic economic theories, transaction cost economics and the resource-based view. The main research question is how the changing customer values should be taken into account when planning business in a networked environment. The main question is divided into questions that form the basic research problems for the separate case studies presented in the five Publications. This research adopts the case study strategy, and the constructive research approach within it. The material consists of data from several Delphi panels and expert workshops, software pilot documents, company financial statements and information on investor relations on the companies’ web sites. The cases used in this study are a mobile multi-player game value network, smart phone and “Skype mobile” services, the business models of AOL, eBay, Google, Amazon and a telecom operator, a virtual city portal business system and a multi-play offering. The main contribution of this dissertation is bridging the gap between firm resources and customer value. This has been done by theorizing the business model concept and connecting it to both the resource-based view and customer value. This thesis contributes to the resource-based view, which deals with customer value and firm resources needed to deliver the value but has a gap in explaining how the customer value changes should be connected to the changes in key resources. This dissertation also provides tools and processes for analyzing the customer value preferences of ICT services, constructing and analyzing business models and business concept innovation and conducting resource analysis.

Tools and data services registry: a community effort to document bioinformatics resources.

Life sciences are yielding huge data sets that underpin scientific discoveries fundamental to improvement in human health, agriculture and the environment. In support of these discoveries, a plethora of databases and tools are deployed, in technically complex and diverse implementations, across a spectrum of scientific disciplines. The corpus of documentation of these resources is fragmented across the Web, with much redundancy, and has lacked a common standard of information. The outcome is that scientists must often struggle to find, understand, compare and use the best resources for the task at hand.Here we present a community-driven curation effort, supported by ELIXIR-the European infrastructure for biological information-that aspires to a comprehensive and consistent registry of information about bioinformatics resources. The sustainable upkeep of this Tools and Data Services Registry is assured by a curation effort driven by and tailored to local needs, and shared amongst a network of engaged partners.As of November 2015, the registry includes 1785 resources, with depositions from 126 individual registrations including 52 institutional providers and 74 individuals. With community support, the registry can become a standard for dissemination of information about bioinformatics resources: we welcome everyone to join us in this common endeavour. The registry is freely available at https://bio.tools.

Use of open educational resources at the UOC

The Open University of Catalonia (UOC: Universitat Oberta de Catalunya) is currently implementing its 2009-2014 Strategic Plan, which devotes an entire section to open educational resources. The working group on this topic is drafting a report that establishes the objectives to be met, analyses the current lay of the land and sets out the actions required to meet the objectives. This paper examines each of these three points.

MultiCampus Open Educational Resources : the case of OER-HE

In this paper we address the implementation strategies regarding Open Educational Resources within a multicampus setting. A comparison is made between 3 institutions that are taking a very different approach: K.U.Leuven, which is a traditional university, the Open Universiteit (Netherlands) which is in the process of starting up the Network Open Polytechnics, and the Universitat Oberta de Catalunya. We are looking deeper into the pedagogical and organizational issues involved in implementing an OER strategy and show how OER holds the promise of flexible solutions for reaching at first sight very divergent goals.
