LINDO

Large scale distributed INDexation of multimedia Objects

Aims

LINDO regards the indexing, storage and retrieval of multimedia objects and studies distributed architectures and indexes (e.g., of metadata, content descriptors, ...) for high-volume data and efficient transfer of the data. The indexes also regard the necessary data in order to accurately answer questions posed in natural language to the repositories. The question answering aspect, in addition, requires technologies for the analysis of the natural language questions and their mapping to the content representations, which are in the form of topic maps (ISO/IEC 13250).

Partners

The LINDO Partners are: Thales Security Systems, CEA List , SUPELEC (Prof. Olivier Pietquin), IRIT ( Prof. Florence Sèdes), SGT, Space Applications Services, Hi-Stor Technologies, DENODO, Telefonica Investigacion y Desarolla , and Infoglobal .

Results

We have drafted a comprehensive state-of-the-art on question answering and have developed technologies for the analysis of the natural language questions and query statements, where we have focused on the recognition and normalization of temporal expressions. This technology is integrated in a demonstrator built in the domain of surveillance videos.
