The task of multi-hop question generation (QG) seeks to generate questions that require a complex reasoning process spans multiple sentences and answers. Beyond the conventional challenges what ask how ask, QG necessitates sophisticated from dispersed evidence across sentences. To address these challenges, knowledge graph-enhanced language model (KGEL) has been developed imitate human for quest...

Open-ended Video question answering (open-ended VideoQA) aims to understand video content and semantics generate the correct answers. Most of best performing models define problem as a discriminative task multi-label classification. In real-world scenarios, however, it is difficult candidate set that includes all possible this paper, we propose Knowledge-constrained Generative VideoQA Algorithm...

Question Answering (QA) systems are the next generation of search technology. A QA system exploits more information about a user’s intention, returning the exact answer to a users query. A crucial component of a QA system is Question Classification (QC), which involves determining the type of information the question is requesting. QC narrows the scope of processing within a QA. For example, “W...

We present a strategy to improve the quality of automatically generated cloze and open cloze questions which are used by the REAP tutoring system for assessment in the ill-defined domain of English as a Second Language vocabulary learning. Cloze and open cloze questions are fill-in-the-blank questions with and without multiple choice, respectively. The REAP intelligent tutoring system [1] uses ...

This paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. The hybrid DC power sources are connected to grid using power electronic converters include DC-DC converter and grid connected voltage source inverter. The power from hybrid power sources is controlled during voltage sag by designing of control strategy for DC-DC converter....

This paper represents a complete survey on Generation Companies’ (GenCos’) optimal bidding strategy problem in restructured power markets. In this regard after an introduction to competitive electricity markets, concept of optimal bidding strategy is presented. Considering large amount of works accomplished in this area a novel classification is implemented in order to categorize the existing d...
