She had worked on the physicochemical parameter and reactor type optimization for production of exopolysaccharide from cyanobacteria as a part of her Master’s Thesis.

Query Optimization and Execution for Multi …

It covers the relational data model, relational algebra, and the Structured Query Language (SQL).

For example, if a search engine understands a phrase to be related to another word or phrase it may return results relevant to that other word or phrase even if the words you searched for are not directly associated with a result. In addition, some search engines will place various types of results at the top of the search results based on implied query related intent or prior search patterns by you or other searchers.

Any semantic query optimizer requires the ability to reason using the semantic information available, in order to draw conclusions which ultimately facilitate the recasting of the original query into a form which can be answered more efficiently.

As part of his master’s thesis he worked on Query Optimization for Hindi-English Code-Mixed query.

N2 - There is a growing need for systems that can process queries, combining both structured data and text. One way to provide such functionality is to integrate information retrieval (IR) techniques in a database management system (DBMS). However, both IR and database research have been separate research fields for decades, resulting in different - even conflicting - approaches to data management. Each DBMS has a component called a "query optimizer", which plays a crucial role in the efficiency and flexibility of the system. So, for successful integration the IR techniques and data structures, as well as the DBMS query optimizer, should be adapted to enable mutual cooperation. The author concentrates on top-N queries - a common class of IR queries. An IR top-N query asks for the N best documents given a set of keywords. The author proposes processing the data in batches as a compromise between IR and DBMS query processing. Experiments with this technique show that porting IR optimization techniques is (still) not a promising option due to the additional administrative overhead. Two new mathematical models are introduced to eliminate this overhead: a model that predicts selectivity, which is a crucial factor in the execution costs, and a model that predicts the quality of the top-N.
