This document outlines a natural language search solution. It identifies key elements in queries and converts them into connected expressions to query a MongoDB database. The solution includes a tokenizer to identify operands and operators. An expression parser uses the stream of tokens to build the equivalent MongoDB query. It supports various operators and integrates external knowledge bases to improve data intelligence. The search API acts as an endpoint for the natural language querying modules. The presentation concludes with an overview of QBurst's MongoDB expertise.

- 10. Solution ❏ Identify key operands & operators within natural language query ❏ Convert them into a series of connected expressions ❏ Dynamically build a query which runs against MongoDB instance ❏ Aggregate search results [Revised]
- 11. Solution
- 13. ❏ Acts an FSA to access inverted index ❏ Emits annotations whenever a buffer matches an operator ❏ Ability to identify common data types such as date, time etc. ❏ Emits the matched expressions as a sequential stream of annotations [Revised] Tokenizer
- 14. Expression Parser ❏ Generated using parser generator ❏ Supports conjunction, disjunction, negation operators ❏ Responsible for taking in a stream of annotations and reducing it ❏ Creates the equivalent MongoDB query during reduction process [Revised]
- 15. Expression Parser Example: Show me Java or PHP openings This will be reduced by EXPR OR_OPERATOR EXPR which has an RHS that will convert this to an OR query in MongoDB
- 16. External Knowledge Bases ❏ Integrated into the expression parser for data intelligence ❏ The application uses NLP date parsers, ConceptNet (knowledge bases) ❏ Improved data intelligence [Revised]

- Modern-day software ecosystem is moving towards a better user experience. This has become critical for user retention. Organizations have realized that, more the user interacts with their application, higher the chances to appreciate the business value of the application. One of the most wanted feature of any user-centric application is the "Search" functionality.

- Our solution is designed to identify key operands and operators within a natural language query and convert them into a series of connected expressions; which are used to dynamically build a query which runs against a MongoDB instance. The final search results are aggregated and shown as standard results.

- The tokenizer is by itself an FSA that has access to the inverted index Tokenizer emits annotations whenever its buffer matches an operator or an entry in the inverted index Tokenizer also has the ability to identify common data types such as date, time etc Tokenizer emits the matched expressions as a sequential stream of annotations

- The expression parser is by itself generated by a parser generator It supports conjunction, disjunction, negation operators and has an associated precedence assigned The parser generator is responsible for taking in a stream of annotations and reducing it. During the reduction process, the expression parser creates the equivalent MongoDB query The process is similar to parsing an expression using a CFG and then at each step reducing the expression to a value (which in this case is the MongoDB query)
- -There are some external knowledge bases and parsers integrated into the Expression parser to make it more intelligent -We use custom NLP date parsers, knowledge bases such as conceptnet to increase the intelligence
- The expression parser by itself is a state machine that uses these series of tokens to make transitions in a finite state machine. Some tokens do cause the finite state machine to reach a final state, in which case expressions are built and stored. The ingestion of the tokens into the expression parser is based on a sliding window model where the window size is dynamic.
