Smart Search Brett Chavis Mike Giles Leslie Jacobson Randy Murdock Patrick Tollison Background Just to Recap: Our project’s purpose was to prove that a search engine could be implemented using natural English sentences and questions as the query. We were to build a system that accepted these natural English queries and manipulated them to access a database, containing a limited number of sites that satisfy a given request. In The Beginning • Began with SQL 7.0 • Attempted for weeks to get SQL running • Consulted numerous SQL books • Consulted with local system administrators • Viewed SQL instructional videos • Visited IT Professionals in Winston Salem for help • Still did not work! Our Solution • Realizing that SQL with English Query is the optimum solution for this problem, but that we no longer had the time to pursue it for our project we decided to implement the project exclusively in Perl. • Next, we identified the major components needed: - User Interface - Parser/Sentence Analyzer - Database - Maintenance Capabilities User Interface • Web page consists initially of a single input box and a submit button • Accepts Plain English Queries or keyword searches. • The system returns 5 or less links to quality sites that match the user’s request. • The system also provides links to Yahoo!, Alta Vista, and AskJeeves already formatted to submit directly to the engine, eliminating retyping for the user. Parser • Creates a keyword search string from the inputted query. • Eliminates certain grammatical constructs and all punctuation. • Modal verbs • Auxiliary verbs • Linking verbs • Pronouns • Prepositions • etc. Database key1,key2,key3 siteName1,siteName2 . . . key4,key5 siteName2,siteName3 siteName1 URL,description siteName2 URL,description siteName3 . URL,description . . Maintenance • The maintenance code we have written is to be used to administer the database. • It provides the following capabilities: • Add information to support a new query • Add a new web site to an existing query • Delete a query • Delete a web site from a query • Modify a web site entry • List the keywords for all currently supported queries In Progress • Maintenance needs to be converted from command-line to web interface • Continued research of grammar for the parser • Database Development • Final System Test • Documentation: Technical Manual Pitfalls • Did not receive SQL Server software until the week preceding Spring Break. • No resources/documentation on English Query • Content in directory was deleted TWICE! • While pursuing SQL, progress was slowed due to limited access to the machine on which it was installed. • No previous experience with databases • Limited experience with Perl among the majority of the team Knowing What We Know Now • SQL 7.0 with English Query is a very powerful utility and would serve best to accomplish this project. • However, given the time constraints, we would have never pursued SQL with English Query from the beginning had we known the complexity involved. • The complexity of composing an English lexer is unreasonable for a semester-long course. Team Successes • Regrouped and completed a working system in limited amount of time. • Fully appreciate team experience of working through major problems and being proud of our accomplishments. • Learned to find resources outside of the University.
