Automatically Annotating Structured Web Data Using a SVM-Based Multiclass Classifierign labels to data items. For data record extraction, a data section re-segmentation algorithm based on visual and content features is introduced to improve the performance of Web data record extraction. We have implemented the proposed approach and tested it with a large set of Web query result pag

Mining Discriminative Itemsets in Data Streams model. Discriminative Itemsets are defined as Itemsets that are frequent in one data stream and their frequency in that stream is much higher than the rest of the streams in the dataset. In order to deal with the data structure size, we propose a pruning process that results in the compact tree str

Modelling Visit Similarity Using Click-Stream Data: A Supervised Approachgeting exists today, it is based on demographic attributes of the visitors. We show that dynamic visitor attributes extracted from their click-stream provide much better predictive capabilities of visitor intent. In this work, we propose a mechanism for identifying similar visitor sessions on a webs

BOSTER: An Efficient Algorithm for Mining Frequent Unordered Induced Subtreesm for rooted labelled unordered trees called the .alanced-.ptimal-search .anonical .orm (BOCF) that can handle the isomorphism problem efficiently. Using BOCF, we define a tree structure guided scheme based enumeration approach that systematically enumerates only the valid subtrees. Finally, we pres

Phrase Queries with Inverted + Direct Indexested index, potentially augmented by selected multi-word sequences (e.g., .-grams or frequent noun phrases). In this work, instead of augmenting the inverted index, we take a radically different approach and leverage the ., which provides efficient access to compact representations of documents. Mode
