Innovative Approaches for efficiently Warehousing Complex Data from the Web [article]

Fadila Bentayeb, Hadj Mahboubi, Cécile Favre, Omar Boussaïd
2017 arXiv   pre-print
In this chapter, we present three innovative researches recently introduced to extend the capabilities of decision support systems, namely (1) the use of XML as a logical and physical model for complex  ...  data warehouses, (2) associating data mining to OLAP to allow elaborated analysis tasks for complex data and (3) schema evolution in complex data warehouses for personalized analyses.  ...  In such a context, it is very helpful to provide users with the most relevant data warehouse model for personalized decision queries.  ...

2018 arXiv   pre-print
We present deep communicating agents in an encoder-decoder architecture to address the challenges of representing a long document for abstractive summarization.  ...  With deep communicating agents, the task of encoding a long text is divided across multiple collaborating agents, each in charge of a subsection of the input text.  ...  Model We extend the CommNet model of Sukhbaatar et al. (2016) for sequence generation.  ...

GeoVIBE: A Visual Interface for Geographic Digital Libraries [chapter]

Guoray Cai
2002 Lecture Notes in Computer Science  
Document relevance may be judged visually by inspecting spatial arrangement and relations of documents in a map view and the similarities among documents defined on a vector space model.  ...  GeoView imposes a geographical order to the document space based on the idea of hypermaps where "icons" and "footprints" may be embedded in maps as the clickable hotspots linking to relevant documents.  ...  In the meantime, geographical model based on multi-layered index maps has limited ability in dealing with the complex, high-dimensional thematic space of textual documents.  ...

An Improved Similarity Matching based Clustering Framework for Short and Sentence Level Text

M. John Basha, K.P. Kaliyamurthie
2017 International Journal of Electrical and Computer Engineering (IJECE)  
Text clustering plays a key role in navigation and browsing process. For an efficient text clustering, the large amount of information is grouped into meaningful clusters.  ...  The similarities between the components are compared and the vector data is created. From the vector data the clustering particle is computed.  ...  A fuzzy relevance measure was used to convert the high dimensional document into a low dimensional document. The proposed clustering technique splitted the relevance space into multiple sub regions.  ...
