Query Segmentation For E-Commerce Sites
… segmentation methodology which is based on prefix tree, mutual information and relative frequency count to compute the score of query pairs and involve Wikipedia for new words recognition. Furthermore, we use two unique E-Commerce evaluation methods to quantify the accuracy of our query …

Analyzing frequent patterns in data streams using a dynamic compact stream pattern algorithm
… the concept of Dynamic Compact Pattern Stream tree (DCPS-tree) algorithm for mining recent data from the continuous data stream. Our DCPS-tree will dynamically achieves frequency descending prefix tree structure with only a single-pass over the data by applying tree restructuring techniques …

Effective and efficient similarity search in databases
… State Set Index (SSI), which is based on a trie (prefix tree) that is interpreted as a nondeterministic finite automaton. For processing range queries, the notion of query plans is introduced in this thesis to describe which similarity indexes to access and which thresholds to apply. The query …

End-to-end Contextual Speech Recognition and Understanding
… if it is incorporated into the biasing list. The tree-constrained pointer generator (TCPGen) component, initially proposed for contextual biasing in ASR and later extended to end-to-end SLU systems, is introduced as the core of all the contributions in this thesis. TCPGen leverages the pointer …
