Are coffee and toffee served in a cup? Ortho-phonologically mediated associative priming.
2008
We report three masked associative priming experiments with the lexical decision task that explore whether the initial activation flow of a visually presented word activates the semantic representations of that word's orthographic/phonological neighbours. The predictions of cascades and serial/modular models of lexical processing differ widely in this respect. Using a masked priming paradigm (stimulus onset asynchrony, SOA = 50 ms), words preceded by ortho-phonologically mediated associated “neighbours” ( oveja–MIEL, the Spanish for sheep–HONEY; note that oveja is a phonological neighbour of abeja, the Spanish for bee) were recognized more rapidly than words preceded by an unrelated word p…
A challenging dissociation in masked identity priming with the lexical decision task.
2013
Abstract The masked priming technique has been used extensively to explore the early stages of visual-word recognition. One key phenomenon in masked priming lexical decision is that identity priming is robust for words, whereas it is small/unreliable for nonwords. This dissociation has usually been explained on the basis that masked priming effects are lexical in nature, and hence there should not be an identity prime facilitation for nonwords. We present two experiments whose results are at odds with the assumption made by models that postulate that identity priming is purely lexical, and also challenge the assumption that word and nonword responses are based on the same information. Our e…
Semantic Approach to Dynamic Coordination in Autonomous Systems
2009
In open systems where the components, i.e. the agents and the resources, may be unknown at design time, or in dynamic and self-organizing systems evolving with time, there is a need to enable the agents to communicate their intentions with respect to future activities and resource utilization to resolve coordination issues dynamically. Ideally, we would like to allow ad-hoc interaction, where two standalone independently-designed systems are able to coordinate whenever a need arises. The Semantic Web based approach presented in this paper aims at enabling agents to coordinate without assuming any design-time ontological alignment of them. An agent can express an action intention using own v…
A probabilistic approach to learning a visually grounded language model through human-robot interaction
2010
A Language is among the most fascinating and complex cognitive activities that develops rapidly since the early months of infants' life. The aim of the present work is to provide a humanoid robot with cognitive, perceptual and motor skills fundamental for the acquisition of a rudimentary form of language. We present a novel probabilistic model, inspired by the findings in cognitive sciences, able to associate spoken words with their perceptually grounded meanings. The main focus is set on acquiring the meaning of various perceptual categories (e. g. red, blue, circle, above, etc.), rather than specific world entities (e. g. an apple, a toy, etc.). Our probabilistic model is based on a varia…
Le «sentiment» comme facteur sémantique : la «sémantique représentationnelle» entre la «linguistique psychologique» et le formalisme
2016
Psychological linguistics - Heymann Steinthal in Germany (1823-1899) and Aleksandr Potebnia in Russia (1835-1891) - has borrowed from the psychology of its time the model of “representative semantics” according to which meanings are representations (Vorstellungen) connected to words. Within this frame, “feeling” (Gefühl) or “feeling tonality” belongs to the verbal representation, in particular to the semantic mechanism. This is also the case of Karl Otto Erdmann’s (1858-1931) semantics which distinguishes within the meaning a “secondary meaning” (Nebensinn) and a “value of feeling” (Gefühlswert). Within the formalist approach (it deals with the “Russian formalism”, 1914-1929), the analysis …
Valodu centru mājaslapu analīze
2018
Šajā darbā uzmanība tiek veltīta galvenokārt Humanitāro zinātņu fakultātes Lietišķās valodniecības centra (LVC) apakšvietnes satura analīzei. Darba mērķis ir noteikt LVC mājaslapas semantiskos kodolus un pārbaudīt vietnes atslēgvārdu un atslēgu vārdkopu saderību Google meklētājprogrammā. Analīze tika veikta ar moderno Google rīku palīdzību un manuāli atpazīstot pašreizējos atslēgvārdus un atslēgu vārdkopas tīmekļa vietnes lapās. Šis pētījums uzsver semantiskā kodola sagatavošanas nozīmi pirms mājaslapas izstrādāšanas, kā arī to, kā ik pa laikam var pārbaudīt atslēgvārdu un atslēgu vārdkopu saderību (Google atpazīšanu). Empīriskais pētījums tika īstenots izmantojot kvalitatīvo un kvantitatīv…
An ontology-based metamodel for multiagent-based simulations
2014
Multiagent-based simulations enable us to validate dierent use-case scenarios in a lot of application domains. The idea is to develop a realistic virtual environment to test particular domain-specic procedures. This paper presents our general framework for interactive multiagent-based simulations in virtual environments. The major contribution of this paper is the integration of the notion of ontology as a core element to the design process of a behavioral simulation. The proposed metamodel describes the concepts of a multiagent simulation using situated agents moving in a semantically enriched 3D environment. The agents perceive the geometric and semantic data in the surrounding environmen…
RDB2OWL
2010
RDB2OWL is a simple approach of mapping relational databases into independently developed OWL ontologies. The approach is based on creating a mapping RDB schema, filling it with mapping information from which SQL scripts are generated that perform the instance-level transformation. We describe the RDB2OWL mapping schema and report on successful application of the technology to the migration of Latvian medical registries data.
Lexico-semantic change: salpuscar ‘to splash’ and variants, a small enigma
2018
Aquest article mostra quin degué ser l’origen del verb salpuscar i la variant salbuscar, sinònim de l’actual esquitar o esquitxar . Subratlla les possibilitats que ofereixen els corpus textuals digitals i la necessitat de tenir present l’estudi contrastiu de llengües (especialment d’atendre l’occità) i la història de la cultura quan es fa semàntica i lexicologia diacròniques del català. Així mateix, s’hi apliquen nocions bàsiques de la semàntica cognitiva en l’estudi del canvi lingüístic. This article shows what must have been the origin of the Catalan verb salpuscar and its variant salbuscar, synonym of the current verb esquitar o esquitxar (‘to splash’). It highlights the possibilities of…
