Corroborating Information from Disagreeing Views (2010)
Galland, Alban, Abiteboul, Serge, Marian, Amélie, Senellart, Pierre
We consider a set of views stating possibly conflicting facts. Negative facts in the views may come, e.g., from functional dependencies in the underlying database schema. We want to predict the truth...

The Web has enabled the availability of a huge amount of useful information, but has also eased the ability to spread false information and rumors across multiple sources, making it hard to...
Fuzzy Multi-Dimensional Search in the Wayfinder File System (2009)
Christopher Peery, Wei Wang, Amélie Marian, Thu D. Nguyen
Abstract — With the explosion in the amount of semi-structured data users access and store, there is a need for complex search tools to retrieve often very heterogeneous data in a simple and...
Adaptive Processing of Top-k Queries in XML Abstract (2008)
Amélie Marian, Sihem Amer-yahia
The ability to compute top-k matches to XML queries is gaining importance due to the increasing number of large XML repositories. The efficiency of top-k query evaluation relies on using scores to...
Abstract Projecting XML Documents (2008)
XQuery is not only useful to query XML in databases, but also to applications that must process XML documents as files or streams. These applications suffer from the limitations of current...

With the explosion in the amount of semi-structured data users access and store in personal information management systems, there is a need for complex search tools to retrieve often very...
Circumventing Data Quality Problems (2006)
Using Multiple Join, Yannis Kotidis, Amélie Marian
We propose the Multiple Join Path (MJP) framework for obtaining high quality information by linking fields across multiple databases, when the underlying databases have poor quality data, which are...
ABSTRACT Evaluation of Top-k Queries over Structured and Semi-structured Data (2005)
Traditionally, queries over structured (e.g., relational) and semi-structured (e.g., XML) data identify the exact matches for the queries. This exact-match query model is not ap-propriate for many...

Optimizing top-k selection queries over multimedia repositories (2004)
Surajit Chaudhuri, Ieee Computer Society, Luis Gravano, Amélie Marian
Abstract—Repositories of multimedia objects having multiple types of attributes (e.g., image, text) are becoming increasingly common. A query on these attributes will typically request not just a...
Projecting XML Documents (2003)
XQuery is not only useful to query XML in databases, but also to applications that must process XML documents as files or streams. These applications suffer from the limitations of current...
Evaluating top-k queries over web-accessible databases (2002)
Amélie Marian, Nicolas Bruno, Luis Gravano
A query to a web search engine usually consists of a list of keywords, to which the search engine responds with the best or “top ” k pages for the query. This top-k query model is prevalent over...

Detecting changes in xml documents (2002)
Grégory Cobéna, Serge Abiteboul, Amélie Marian
We present a diff algorithm for XML data. This work is motivated by the support for change control in the context of the Xyleme project that is investigating dynamic warehouses capable of storing...

Change-Centric Management of Versions in an XML Warehouse (2001)
Amélie Marian, Serge Abiteboul, Grégory Cobéna, Laurent Mignet
We present a change-centric method to manage versions in a Web WareHouse of XML data. The starting points is a sequence of snapshots of XML documents we obtain from the web. By running a diff...
