When the Social Meets the Semantic: Social Semantic Web or Web 2.5

The social trend is progressively becoming the key feature of current Web understanding (Web 2.0). This trend appears irrepressible as millions of users, directly or indirectly connected through social networks, are able to share and exchange any kind of content, information, feeling or experience. Social interactions radically changed the user approach. Furthermore, the socialization of content around social objects provides new unexplored commercial marketplaces and business opportunities. On the other hand, the progressive evolution of the web towards the Semantic Web (or Web 3.0) provides a formal representation of knowledge based on the meaning of data. When the social meets semantics, the social intelligence can be formed in the context of a semantic environment in which user and community profiles as well as any kind of interaction is semantically represented (Semantic Social Web). This paper first provides a conceptual analysis of the second and third version of the Web model. That discussion is aimed at the definition of a middle concept (Web 2.5) resulting in the convergence and integration of key features from the current and next generation Web. The Semantic Social Web (Web 2.5) has a clear theoretical meaning, understood as the bridge between the overused Web 2.0 and the not yet mature Semantic Web (Web 3.0).Pileggi, SF.; Fernández Llatas, C.; Traver Salcedo, V.

A Train-on-Target Strategy for Multilingual Spoken Language Understanding

[EN] There are two main strategies to adapt a Spoken Language Understanding system to deal with languages different from the original (source) language: test-on-source and train-on-target. In the train-ontarget approach, a new understanding model is trained in the target language, which is the language in which the test utterances are pronounced. To do this, a segmented and semantically labeled training set for each new language is needed. In this work, we use several general-purpose translators to obtain the translation of the training set and we apply an alignment process to automatically segment the training sentences. We have applied this train-on-target approach to estimate the understanding module of a Spoken Dialog System for the DIHANA task, which consists of an information system about train timetables and fares in Spanish. We present an evaluation of our train-on-target multilingual approach for two target languages, French and EnglishThis work has been partially funded by the project ASLP-MULAN: Audio, Speech and Language Processing for Multimedia Analytics (MEC TIN2014-54288-C4-3-R).García-Granada, F.; Segarra Soriano, E.; Millán, C.; Sanchís Arnal, E.; Hurtado Oliver, LF.

A nyelvi időkezelés és intenzionalitás nem-modális megközelítése = A non-modal approach to temporality and intensionality

A két éves posztdoktori kutatás célkitűzése a progresszív aspektus hagyományos szemantikai elemzésének radikális újragondolása volt, elsősorban a Varasdi (2010)-ben kifejtett elképzelésre építve. E munka során sikerült kimutatni, hogy az a hagyományosan elfogadott vélekedés, miszerint a progresszív aspektus szemantikája az események "normális folytatására" támaszkodik, minden intuitív vonzereje ellenére sem tartható, mert nem tud elszámolni az egyre növekvő számú ellenpéldával. A munka másik eredménye egy olyan új formális szemantikai elmélet, amely a normalitás fogalma helyett az esemény kulminációjának szükséges feltételeire épít, és képes kezelni a sztenderd elmélettel szemben felhozott ellenpéldákat. Ez az elmélet mind nyelvészeti, mind filozófiai szempontból jobban megalapozott, mint az előzményéül szolgáló Varasdi (2010), de megőrzi és továbbfejleszti annak előnyös vonásait. Tekintetbe véve a progresszív aspektus problematikájának szoros kapcsolatát nyelvészeti, filozófiai és kognitív tudományi problémákkal, egy a progresszívre vonatkozó új elméletnek nem csak a szűken vett formális aspektológiában, hanem számos egyéb területen is megtermékenyítő hatása lehet. | The goal of this two-year long postdoctoral research was to rethink the traditional semantic analysis of the progressive aspect, primarily on the basis of the theory elaborated in Varasdi (2010). As a result of the research done in this period it has been shown that the received view according to which the semantics of the progressive aspect is based on the ""normal continuation"" of the event is not tenable in spite of its intuitive attractiveness, because it cannot cope with the growing number of counter-examples. Another result of the work done is a new formal semantic theory that is based on the necessary conditions of the culmination of the event instead of normalcy, and is able to handle the counter-examples to the standard theory. The theory is not only better motivated from a linguistic and philosophical point of view than its predecessor in Varasdi (2010), but also preserves and improves upon its favorable features. In view of the close connections between the problems of the progressive aspect and those of theoretical linguistics, philosophy and cognitive science, a new theory of the progressive may not only influence research in formal aspectology in particular, but may have an effect upon numerous other scientific areas as well

A Survey of Volunteered Open Geo-Knowledge Bases in the Semantic Web

Over the past decade, rapid advances in web technologies, coupled with innovative models of spatial data collection and consumption, have generated a robust growth in geo-referenced information, resulting in spatial information overload. Increasing 'geographic intelligence' in traditional text-based information retrieval has become a prominent approach to respond to this issue and to fulfill users' spatial information needs. Numerous efforts in the Semantic Geospatial Web, Volunteered Geographic Information (VGI), and the Linking Open Data initiative have converged in a constellation of open knowledge bases, freely available online. In this article, we survey these open knowledge bases, focusing on their geospatial dimension. Particular attention is devoted to the crucial issue of the quality of geo-knowledge bases, as well as of crowdsourced data. A new knowledge base, the OpenStreetMap Semantic Network, is outlined as our contribution to this area. Research directions in information integration and Geographic Information Retrieval (GIR) are then reviewed, with a critical discussion of their current limitations and future prospects

About the nature of Kansei information, from abstract to concrete

Designer’s expertise refers to the scientific fields of emotional design and kansei information. This paper aims to answer to a scientific major issue which is, how to formalize designer’s knowledge, rules, skills into kansei information systems. Kansei can be considered as a psycho-physiologic, perceptive, cognitive and affective process through a particular experience. Kansei oriented methods include various approaches which deal with semantics and emotions, and show the correlation with some design properties. Kansei words may include semantic, sensory, emotional descriptors, and also objects names and product attributes. Kansei levels of information can be seen on an axis going from abstract to concrete dimensions. Sociological value is the most abstract information positioned on this axis. Previous studies demonstrate the values the people aspire to drive their emotional reactions in front of particular semantics. This means that the value dimension should be considered in kansei studies. Through a chain of value-function-product attributes it is possible to enrich design generation and design evaluation processes. This paper describes some knowledge structures and formalisms we established according to this chain, which can be further used for implementing computer aided design tools dedicated to early design. These structures open to new formalisms which enable to integrate design information in a non-hierarchical way. The foreseen algorithmic implementation may be based on the association of ontologies and bag-of-words.AN

Three symbol ungrounding problems: Abstract concepts and the future of embodied cognition

A great deal of research has focused on the question of whether or not concepts are embodied as a rule. Supporters of embodiment have pointed to studies that implicate affective and sensorimotor systems in cognitive tasks, while critics of embodiment have offered nonembodied explanations of these results and pointed to studies that implicate amodal systems. Abstract concepts have tended to be viewed as an important test case in this polemical debate. This essay argues that we need to move beyond a pretheoretical notion of abstraction. Against the background of current research and theory, abstract concepts do not pose a single, unified problem for embodied cognition but, instead, three distinct problems: the problem of generalization, the problem of flexibility, and the problem of disembodiment. Identifying these problems provides a conceptual framework for critically evaluating, and perhaps improving upon, recent theoretical proposals
