This paper presents a statistical approach to tree to tree correction adapted to structural information retrieval. It consits on indexing content and structure and use the both index in an information retrieval process. Retrieval process uses extended document and query structures and returns some fragments that follow the content and structure of the… (More)
This paper presents an information retrieval model in XML documents based on tree matching, using the query relaxation principle. Queries and documents are represented by extended trees. An extended tree is built starting from the original tree, with additional weighted virtual links between each node and its indirect descendants allowing to directly reach… (More)
The exploitation of heterogeneous clinical sources and healthcare records is fundamental in clinical and translational research. The determination of semantic similarity between word pairs is an important component of text understanding that enables the processing and structuring of textual resources. Some of these measures have been adapted to the… (More)
