					CSCI 572: Information Retrieval and
  Search Engines: Summer 2010

        Prof. Chris A. Mattmann
                          The Class
• Will give you a complete treatment of the area of search engines and
  information retrieval
   – The fundamental building blocks of the web and search engines
       • The Search Engine Architecture proposed by Brin/Page
       • Understanding algorithms for ranking pages
       • Understanding technologies for characterizing, downloading,
         parsing, indexing, searching and disseminating web content
   – Advanced topics in search engines such as BigData and distributed
      computation
• Will equip you with the necessary skills to design complex, real-
  world search engines

                   What we’ll cover
• Theory
   –   Understanding of basic information retrieval
   –   Search engine querying
   –   Search engine ranking
   –   Architecture of search engines and technologies
   –   Design Patterns
• Practice
   – Modern search engine technologies from Apache

               Course Presentation
• Each week, we’ll read a few research papers on
  search engines
• For the first part of the course (5 weeks), I’ll
  lecture on the general topics that the research
  papers cover
   – The search engine architecture: fetching, parsing,
     indexing, querying, distributed computation, etc.
• For the last part of the course (~5 weeks), each one
  of you will present on one of the research papers
  we covered in the first 5 weeks

                    Course Presentation
• What I’m looking for (~20 minutes of presentation, with ~5
  mins questions at the end)
   – You understood the paper
   – Discussion of related work and background
   – Discussion of why should I care about the topic
          • And more importantly why your fellow classmates should care
   – Relation of your paper to the lecture slides I gave on the topic
   – Simple summarization and description of the algorithm and/or
     technology introduced in the paper
   – What were the results/contributions/conclusions of the paper
   – Your evaluation of Pros of the paper
   – Your evaluation of Cons of the paper

                   Course Presentation
• What I’m NOT looking for
   –   Plagiarism
   –   Repetition
   –   Cutting/Pasting out of the paper
   –   Regurgitation
   –   You to follow the EXACT set of bullets that I gave on the prior slide
• You should be looking to be innovative – show the class and
  me that you really understood what was in the paper
   – Treat it like a conference presentation

                      Course Project
• You will get to leverage one or a combination of several
  Apache software technologies
   – Nutch, Tika, Lucene, Solr, Hadoop, HBase, Hive, Cassandra, etc.
• You will make a significant contribution to one or more of
  the above communities
• Deliverables
   – A 2 page project proposal
