We have only submitted runs for the classiflcation task on Dutch and English languages. Our approach has consisted in the use of a particular Informa- tion Retrieval system as classiflcation architecture, using the speech transcriptions as textual queries and generating textual corpus for

The main interest of our experimentation is the characterization of queries where WSD is a useful tool. That is, which issues must be fulfllled by a query in order to apply an

We have developed a system made up of three main modules: the Translation Subsystem, that works with queries into Spanish and German against English collection; the Query Expansion subsystem, that integrates a Named Entity Recognizer, a thesaurus expansion module and a geographical

We have developed an approach based on several lexical measures integrated by means of different machine learning models. Based on lexical features it obtains a 41% of accuracy in answer validation for the Question-Answering task.

This technique also includes the geographic expansion of the topics. Moreover, several experiments related to the use of keywords and hyponyms in the filtering process are performed. We also use a new approach in the re-ranking process based on the original position of each

This approach consists in applying an Information Retrieval (IR) system as classifier. We have generated a document collection for each topic class predefined. This collection has been composed of documents retrieved using the Google search engine. Following the IR strategy, we have used the speech transcriptions of the

Our approach is made up of two main subsystems: the speech-based retrieval module and the image-based retrieval module. The aim of the experiments presented in this work is to establish a baseline approach to resolve the automatic video image retrieval task, making use of the speech

It could be interesting and useful for determining which of the most used IR systems works better in GIR task. In the experiments, we have used the

That is, which issues must be fulfilled by a query in order to apply an state-of-art WSD tool? In addition, we have evaluated several approaches in order to apply WSD. We have used several types of indices. Thus, we have generated 13 indices
