   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; lexical richness; foreign language writing; Spanish; linguistic complexity; TBLT; task-based; task complexity; vocabulary; second language acquisition; riqueza léxica; ELE; producción escrita; complejidad lingüística; enfoque por tareas; complejidad de la tarea; vocabulario; adquisición de segundas lenguas; romanska språk med inriktning mot spanska; Romance Languages; Specialisation in Spanish;

   Sammanfattning : The present study explored lexical richness in the written production of Swedish university students of Spanish as a foreign language. Two aspects of lexical richness were investigated in the study, i.e., diversity (the ability to use a varied lexical repertoire), and sophistication (the proportion of relatively infrequent words).

3. 2. Planning in Inhabited Environments : Human-Aware Task Planning and Activity Recognition

   Författare :Marcello Cirillo; Lars Karlsson; Alessandro Saffiotti; Fredricio Pecora; Nau Dana; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human-aware planning; planning under uncertainty; activity recognition; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

   Sammanfattning : Promised some decades ago by researchers in artificial intelligence and robotics as an imminent breakthrough in our everyday lives, a robotic assistant that could work with us in our home and our workplace is a dream still far from being fulfilled. The work presented in this thesis aims at bringing this future vision a little closer to realization. LÄS MER

4. 3. Computational models for intent recognition in robotic systems

   Författare :Michele Persiani; Thomas Hellström; Sven Magg; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intent Recognition; Robotics; Plan Recognition; Speech; Affordances; Computer Science; datalogi;

   Sammanfattning : The ability to infer and mediate intentions has been recognized as a crucial task in recent robotics research, where it is agreed that robots are required to be equipped with intentional mechanisms in order to participate in collaborative tasks with humans.Reasoning about - or rather, perceiving - intentions enables robots to infer what other agents are doing, to communicate what are their plans, or to take proactive decisions.

5. 4. Information state based speech recognition

   Författare :Rebecca Jonson; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; dialogue systems; speech recognition; language modelling; dialogue move; dialogue context; ASR; higher level knowledge; linguistic knowledge; N-Best re-ranking; confidence scoring; confidence annotation; information state; ISU approach;

   Sammanfattning : One of the pitfalls in spoken dialogue systems is the brittleness of automatic speech recognition (ASR). ASR systems often misrecognize user input and they are unreliable when it comes to judging their own performance. LÄS MER
