ir-course-uoi

The project for the Information Retrieval course @cse.uoi.gr is about implementing a search engine for Wikipedia articles using Apache Lucene.

In ir-course-uoi-data, you can find the implementation of a custom crawler and HTML preprocessor to extract text from the HTML pages scrapped.

This search engine supports multiple features. For example:

• Keyword/Phrase/Wildcard/Boolean Queries
• Spelling correction
• Searching in specific article sections (i.e. Title, Content, Multimedia, Quotes, References)
• Displaying a short description/summary for each result, including highlighting of search terms
• Sorting based on Relevance, Publication Date or Modification Date (Ascending/Descending)
• Narrowing of results based on time of last update or time of publication (Anytime, day, week, 1/3/6/12 months)
