An Improved Approach for Long Tail Advertising in Sponsored Searchrs also tend to target head query keywords, thereby creating an imbalance in demand for head and tail keywords. This leads to under-utilization of ad space of tail query keywords. In this paper, we have explored a mechanism that allows the advertisers to bid on concepts rather than keywords. The tai

Efficient Regular Expression Matching on Compressed Stringsgs, such as high compression ratio and slower decompression speed than LZ77 (a variant of LZ78). In this paper, we study regular expression matching on LZ77 compressed strings. To address this problem, we propose an efficient algorithm, namely, ., utilizing the ., i.e., a prefix and a suffix, and .

Mining Top-, Distinguishing Temporal Sequential Patterns from Event Sequencesnalysis. Distinguishing sequential patterns can help characterize the differences between two or more sets/classes of sequences, and can be used to understand those sequence sets/classes and to identify informative features for classification and so on. However, previous studies have not considered

Similarity Search Combining Query Relaxation and Diversification and processes queries in several small sets to retrieve more diverse results. The balance of similarity and diversity is determined through setting a threshold, which has a default value and can be adjusted according to users’ preference. The performance and efficiency of our system are demonstrate

Approximate OLAP on Sustained Data Streamsata streams’ summaries in comparatively smaller space and can give approximate answers to OLAP queries..OLAP analysts query different nodes in the OLAP cube interactively. To support such analysis by the PLA-based data cube without the unnecessary amplification of querying errors, inherent in the PL
