• ### Lecture ECE 250 - Algorithms and data structures: Binary search trees

In computer science, binary search trees (BST), sometimes called ordered or sorted binary trees, are a particular type of containers: data structures that store "items" (such as numbers, names etc.) in memory. This topic covers binary search trees: Abstract Sorted Lists, background, definition and examples,...

• ### Data structures and Algorithms: Search Trees

Data structures and Algorithms: Search Trees presents about Binary Search Trees, AVL Trees, Red-Black Trees, Ordered Dictionaries, Performance, AVL Tree Definition, Insertion in an AVL Tree.

• ### Lecture Data structures and other objects using C++ - Chapter 10b: Binary search trees

One of the tree applications in chapter 10 is binary search trees. In chapter 10, binary search trees are used to implement bags and sets. This presentation illustrates how another data type called a dictionary is implemented with binary search trees.

• ### Comparing Association Rules and Decision Trees for Disease Prediction

Association rules represent a promising technique to find hidden patterns in a medical data set. The main issue about mining association rules in a medical data set is the large number of rules that are discovered, most of which are irrelevant. Such number of rules makes search slow and interpretation by the domain expert difficult. In this work, search constraints are introduced to find only medically significant association rules and make search more efficient.

• ### Data Structures and Algorithms - Chapter 7b: AVL Tree

AVLTree is: •A Binary Search Tree, •in which the heights of the left and right subtreesof the root differ by at most 1, and •the left and right subtreesare again AVLtrees.

• ### Data Structures and Algorithms - Chapter 7 -Tree

In computer science, a binary search tree (BST), which may sometimes also be called an ordered or sorted binary tree, is a node-based binary tree data structure which has the following properties:[1] The left subtree of a node contains only nodes with keys less than the node's key. The right subtree of a node contains only nodes with keys greater than the node's key. Both the left and right subtrees must also be binary search trees. There must be no duplicate nodes. Generally, the information represented by each node is a record rather than a single data element.

• ### AVL Tree

AVL Tree is: • A Binary Search Tree, • in which the heights of the left and right subtrees of the root differ by at most 1, and • the left and right subtrees are again AVL trees. The name comes from the discoverers of this method, G.M.Adel'son-Vel'skii and E.M.Landis. The method dates from 1962. .Balance factor Balance factor: • left_higher: HL = HR + 1 • equal_height: • right_higher:

• ### Báo cáo khoa học: "Language Identiﬁcation of Search Engine Queries"

We consider the language identiﬁcation problem for search engine queries. First, we propose a method to automatically generate a data set, which uses clickthrough logs of the Yahoo! Search Engine to derive the language of a query indirectly from the language of the documents clicked by the users.

• ### Báo cáo khoa học: "Searching Questions by Identifying Question Topic and Question Focus"

This paper is concerned with the problem of question search. In question search, given a question as query, we are to return questions semantically equivalent or close to the queried question. In this paper, we propose to conduct question search by identifying question topic and question focus. More specifically, we first summarize questions in a data structure consisting of question topic and question focus. Then we model question topic and question focus in a language modeling framework for search.

• ### Báo cáo khoa học: "Improving Grammaticality in Statistical Sentence Generation: Introducing a Dependency Spanning Tree Algorithm with an Argument Satisfaction Model"

Abstract-like text summarisation requires a means of producing novel summary sentences. In order to improve the grammaticality of the generated sentence, we model a global (sentence) level syntactic structure. We couch statistical sentence generation as a spanning tree problem in order to search for the best dependency tree spanning a set of chosen words. We also introduce a new search algorithm for this task that models argument satisfaction to improve the linguistic validity of the generated tree. ...
