Web information extraction and annotation has been an active research area in recent years. Many systems rely on human users to mark the desired information on sample pages and label the marked data at the same time, and then the system can induce a series of rules (wrapper) to extract the same set of information […]
Tree Patterns Used in Optimization Processes
A comprehensive survey about XML tree patterns, which are nowadays considered crucial in XML querying and its optimization. We first compare TPs from a structural point of view, concluding that the richer a TP is with matching possibilities, the larger the subset of XQuery/XPath it encompasses, and thus the closer to user expectations it is.

The Method is applied to correction of spelling errors in queries Reformulation
This paper addresses string transformation, which is an essential problem, in many applications. In natural language processing, pronunciation generation, spelling error correction, word transliteration, and word stemming can all be formalized as string transformation. String transformation can also be used in query reformulation and query suggestion in search. In data mining, string transformation can be […]
Inferring user search goals by Clustering Pseudo Documents
A novel approach has been proposed to infer user search goals for a query by clustering its feedback sessions represented by pseudo-documents. The introduce feedback sessions to be analyzed to infer user search goals rather than search results or clicked URLs. Both the clicked URLs and the un clicked ones before the last click are […]
A proposal for direct and indirect Discrimination prevention
The wide deployment of information systems based on data mining technology in decision making, the issue of antidiscrimination in data mining did not receive much attention until 2008. Some proposals are oriented to the discovery and measure of discrimination. Others deal with the prevention of discrimination. The approach is based on mining classification rules (the […]
Method for measuring relationships using Generalized flow
To measure implicit relationships between two objects on the Wikipedia information network. The relationship is a more general concept than similarity, we discuss existing methods for measuring either relationships or similarities. A keyword has grown in this decade, while knowledge search has recently been researched to obtain knowledge of a single object and relationships between […]
