The challenge of measuring semantic similarity between words is to find a method that can simulate the thinking process of human. The use of computers to quantify and compare semantic similarities has become an important area of research in various fields, including artificial intelligence, knowledge management, information retrieval and natural language(More)
Computing semantic similarity/relatedness between concepts and words is an important issue of many research fields. Information theoretic approaches exploit the notion of Information Content (IC) that provides for a concept a better understanding of its semantics. In this paper, we present a complete IC metrics survey with a critical study. Then, we propose(More)
This paper presents an information retrieval model in XML documents based on tree matching. Queries and documents are represented by extended trees. Therefore only one level separates between each node and its indirect descendants. This allows to compare easily structural constraints of the user query and the document structure with flexibility. Thus(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)
The goal of an XML retrieval system is to select from a set of XML documents all elements (nodes) that fit the user information need, usually expressed by a set of keywords with some structural conditions. Structural conditions are simply given by an ordered list of tag names that gives the target element where to search for relevant content. Consequently a(More)
Computing Semantic Similarity (SS) between words is an important issue of many research fields. Several features from knowledge databases can be involved in the definition of semantic computing models. Gloss-based approaches exploit the short and precise description for a concept for better expressing its semantics. In this paper, we propose a new(More)
