Conventional approaches to XML clustering by content and structure are generally affected by a limitation due to the adoption of the bag-of-word model for the representation of their textual contents. This choice may lead to consider structure-constrained textual items of separate XML documents as related, even though the actual meaning of such items in their respective contexts is different. To overcome...
The increasing amount of available XML documents collections has led to the emergence of new challenges in information retrieval field. Therefore, multiple sources of evidence were used to retrieve XML elements at different levels of granularity. XML information retrieval combines textual and structural information to perform different information retrieval tasks. In this paper, we propose a new approach...
Query Expansion is an important component for information retrieval systems. It makes possible the reformulation of the initial user query by adding new terms. In this paper, we propose a new approach for term selection in the relevance feedback process. This approach, based on Rocchio formula, is an adaptation to the XML information retrieval context. It can resolve two major problems specific to...
Simulators are an essential tool for researching and developing new systems, architectures or protocols. They have played a key role in the history of the Internet and the Web. This paper highlights the view that the simulation-based research will continue to take part in the evolution of paradigms associated with the Internet and the Web of Things. In this work, we present a simulator whose ultimate...
XML Information Retrieval is approach to identify the appropriate answer granularity and controlling to elements overlap. Recently, the demand for integrating Full Text Search and relational search has increased dramatically. The RDBMS implementation is generally much worse in the performance than the IR engine implementation. Especially, when a query is processed in the RDBMS, the number of join...
This paper presents the results of an experimental study of some similarity measures used for both Information Retrieval and Document Clustering. Our results indicate that the cosine similarity measure is superior than the other measures such as Jaccard measure, Euclidean measure that we tested. Cosine Similarity measure is particularly better for text documents. Previously these measures are compared...
In this paper, we are interested in content oriented XML information retrieval whose aim is to retrieve not a list of relevant documents, but only fragments of document (XML element) relevant to the user information need. Retrieved XML elements must not only contain relevant information but also be at good level of granularity. The coexistence of content and structural information in XML documents...
The use of technical articles in scientific and academic scopes is a well-known way to extend new creations and researching jobs throughout the world, mainly as a communication medium of knowledge among educational professionals. Nowadays, with no doubt, the Internet, is the usual way to spread any kind of documentation. Authors send the contents of their publications, based on a typical scheme composed...
Context-aware computing benefits mobile applications by adapting systems behavior through user surrounding. However, contextualized information retrieval for mobile user in mobile P2p environment still remains a challenging problem. In this paper, we present JHPeer framework for mobile information retrieval (IR) in hybrid peer to peer (P2P) networks. JHPeer incorporates context engine to fit on mobile...
Business documents exchanged in a service-oriented context play a crucial role in the definition of service interfaces. Only if both partners have a common agreement on the data exchanged, automated business interactions are possible. The United Nations Center for Trade Facilitation and Electronic Business (UN/CEFACT) provides a reliable and interoperable solution for conceptual business document...
The software reuse initiatives are better implemented when there is an efficient way to find the reusable assets. However, the search and retrieval of such information is considered a big deal in literature, once there is a gap between what the software engineer would like to retrieve and what is stored in the repository. Thus, this paper presents an efficient way to reduce this problem and aid search...
In this paper we present two adaptations of the PageRank algorithm to collections of XML documents and the experimental results obtained for the Wikipedia collection used at INEX-1 2007. These adaptations to which we referred as ldquoDOCRANK and TOPICAL_docrankrdquo allow the re-rank of the results returned by the base run execution to improve retrieval quality. Our experiments are performed on the...
Both of XML document and user's query are represented by the set of paths from the root node to leaf nodes. So the context and content information contained in the corresponding path is a vital important clue to research XML retrieval. This paper presents an approach, NPathSim, for measuring similarity between two paths. XML Path retrieval was performed to evaluate the performance of NPathSim. The...
