Keyword searches on XML and relational databases, as opposed to traditional structured query, have been widely studied in recent years. Users are freed from learning the query languages and database schemas by simply issuing some keywords to query the databases. Unlikely traditional structured query languages which can represent user query request precisely, a keyword query only contains some keywords which may have different interpretations and cannot capture the user’s intention precisely.
Current approaches to XML keyword search are structure-based because they mainly rely on the exploration of the structure of XML data. They can be classified as tree-based and graph-based search. The tree-based search is used when an XML document is modeled as a tree, i.e. without ID references (IDREFs), while the graph-based search is used for XML documents with IDREFs. Almost all tree-based approaches are based on some variations of LCA (Least Common Ancestor) semantics such as SLCA and ELCA. Due to the unawareness of real semantics in XML data, these LCA-based approaches suffer from several serious limitations such as meaningless answers, duplicated answers, missing answers, and answers which depend highly on the hierarchical structure of the XML data, etc.
Current approaches to keyword search on relational databases can be classified as data graph based and schema graph based. Data graph based keyword search on relational databases takes a relational database as a data graph where a tuple in the database is represented as a node in the data graph, and a foreign key-key reference between two tuples in the database is represented as an edge between the two nodes which represent the two tuples. An answer of a user keyword query is defined as a minimal connected subgraph which contains nodes that match keywords in the keyword query. This sort of graph search is equivalent to the Steiner tree problem, which is NP-complete. Research in relational keyword search has been focused on the efficient computation of answers from multiple tuples as well as strategies to rank and output the most relevant ones. Existing relational keyword search techniques suffer from the problems of returning incomplete, duplicated, and meaningless answers. Moreover, the resulting answers highly depend on the schema of the relational database and the difficulty of interpreting the intuitive meanings of the returned Steiner trees as answers.
We thoroughly point out mismatches between answers returned and the expectations of common users in keyword search in XML and relational databases. Through detailed analysis of these mismatches, we discovered the main reasons for the mismatches are due to the unawareness of the semantics of object, relationship, and attribute of object/relationship in the databases. We refer to them as ORA-semantics. In particular, unawareness of objects causes missing answers, duplicated answer, and meaningless answers.
In this talk, we will discuss how ORA-semantics can be used to overcome the above-mentioned problems in existing keyword search approaches and how to improve the effectiveness and performance of keyword search.
Dr Ling Tok Wang is a professor in Computer Science at the National University of Singapore. He was Head of IT Division, Deputy Head of the Department of Information Systems and Computer Science, and Vice Dean of the School of Computing. He received his PhD and M.Math, both in Computer Science, from University of Waterloo (Canada), and BSc in Mathematics from Nanyang University (Singapore).
His current research interests include Database Modeling, Semi-Structured Data Model, XML Twig Pattern Query Processing, XML and Relational Database Keyword Query Processing.
He serves/served on the steering committees of 4 international conferences, including ER and DASFAA.

Abstract
Wikipedia defines Entrepreneurship as the quality of being an entrepreneur, i.e. one who "undertakes an enterprise". The term puts emphasis on the risk and effort of individuals who own and manage a business, and on the innovations that result from their pursuit of economic success.Based on a naïve assumption that the attendees plan to become entrepreneurs, the session uses a simple framework to share the speaker's personal experiences and assist the attendees to build their own roadmap to entrepreneurship.

He is highly self motivated and goal-oriented professional committed to pursuing a long-term career in lecturing and research. His professional interests focus on swarm robotics and optimization.
In addition, he serves as committee for various conferences held by IEEE RAS chapter.
Research interest
MANUFACTURING PLANNING AND SCHEDULING
To solve problems in assignment of machines to operations and the scheduling of operations on the assigned machines in Flexible Job shop Scheduling Problem with multi-objectives using heuristics or meta-heuristics. Various swarm intelligence algorithms (such as particle swarm optimization (PSO), simulated annealing technique (SA)) are hybridized to solve the Job Shop Scheduling Problems. To optimize assembly line balancing problems using artificial intelligence algorithms and heuristics. To compare and contrast various algorithms used to solve the above mentioned problem domains with the developed algorithms.
MOBILE ROBOTICS
To implement developed learning algorithms on various problems domains such as cart pole problem, soccer, mountain car problem and game theories such as Backgammon, Blackjack and Chess. To built a commercial mobile robot for research purposes. The mobile robot will consist of several common modules such as gripper module, camera module and communication turret. Further development to solve mobile robot problem domains such as mapping, localization, object detection using stereo vision, odometry issues, on-board database, self-charging capabilities and on-board neural network platform. The mobile robot will be built in a platform that supports major programming languages namely C/C++ language, Visual Basic, JAVA, MATLAB and LabView.
