A Geometric Approach to Automatic Description of Iconic Scenes
2005
It is proposed a step towards the automatic description of scenes with a geometric approach. The scenes considered are composed by a set of elements that can be geometric forms or iconic representation of objects. Every icon is characterized by a set of attributes like shape, colour, position, orientation. Each scene is related to a set of sentences describing its content. The proposed approach builds a data driven vector semantic space where the scenes and the sentences are mapped. Sentences and scene with the same meaning are mapped in near vectors and distance criteria allow retrieving semantic relations.
Analogical reasoning performance and organization is influenced by the type of semantic distractors : an investigation with adults
2015
International audience; The way participants adapt their search to the specifics of different types of analogies is not fully understood. We compared the effects of two types of semantic distractors. The first were related to C by a semantic relation which had nothing to do with the semantic relation used in the A:B pairs, whereas the second, the so-called "double distractors", were not only related to C but also had a semantic relation similar to the one linking A to B. We used eye-tracking measurements in addition to reaction time and performance indices. We found that performance decreased, and that the solution set was less explored visually with the double distractors than with the for…
Semantisko lauku analīze ziņu rakstos par jaunuzņēmumiem
2022
Semantiskie lauki ir semantiski savienotu vārdu kopa, kas ir saistīti nozīmē. Šī pētījuma mērķis ir analizēt semantiskos laukus ziņu rakstos par jaunuzņēmumiem. Tāpēc šis pētījums ir sadalīts piecās galvenajās nodaļās, lai skatītu teorētisko ietvaru un veiktu empīrisku pētījumu. Pētījumā tiek izmantota satura analīze, lai aprakstītu un analizētu ziņu rakstus par jaunuzņēmumiem, kas ir saistīts ar komponentu analīzes koncepciju. Pēc tam semantiskās attiecības semantiskajos laukos tiek analizētas. Empīriskā pētījuma rezultāti liecina, ka korpusā tika identificēti dažādi semantiskie lauki. Vārds ar vienu nozīmi var veidot dažādus semantiskos laukus ar atšķirīgiem vārdiem un vārdi semantiskajā …
