3. Models of Information Retrieval

• Boolean query demo
- A graphical Boolean query demo which helps users understand the concept of Boolean matching process.
• Boolean query demo (servlet)
- This demo shows results of two query terms using boolean operators.
• Demo of extended boolean query
- This web page is a demonstration of extended Boolean query. The extend Boolean query is a Boolean query that can have weight incorporated with the term. By using graphical display, user could understand the concept of how the weight can affect the result of a Boolean query more easily.
• Demonstration of Extended Boolean Queries
- Boolean: And, Or, And Not are plainly illustrated in a colorful Java applet.
• Logic Learn Applet
• SMART
- SMART information retrieval experiment package at Cornell University
• SMART: Tutorial for beginners
• Vector space retrieval model demo
- The Vector Model demonstrates how documents are converted into vectors and how Cosine Measure and Euclidean Distance is calculated
• VENN Diagram
• Venn diagram demo
- Venn diagram Java applet demo
• Web-based Boolean Tutorial
- Teaches Boolean document matching and other extensions of Boolean searching.

4. Retrieval Effectiveness (Evaluation)

• Test collections

5. Text Analysis

• Bibliography on Zipf's Law
• Lancaster (Paice/Husk) stemmer
• List of common words
• List of stopwords
• Porter stemmer demo
- This demo converts user inputs into English stems by Porter stemming algorithm
• The Porter Stemmer Algorithm
- Porter stemmer implimentations in various languages including C, Java, Perl
• Visual Thesaurus
- An experiment in language and interface, Plumb Design's Visual Thesaurus is both an artistic exploration and a tool to explore, study, and analyze the structure of language.

- An educational program that teaches Fuzzy Query Search.
• A short genetic algorithm tutorial
• Genetic Algorithms Short Tutorial
• IKONA
- A Modular Architecture For Content Based Image Retrieval Systems - Demo
• Introduction to Genetic Algorithms
- This tutorial targets people with no previous knowledge of genetic algorithms. It covers the original genetic algorithm, introducing all the essential concepts: search space, mutation and crossover, selection and encoding. Pictures are used cleverly to explain the theory, and java applets demonstrate the algorithm in action
• SVM demo
- Support Vector Machine automatic classification model demo. This demo shows 2D vector space and draws classification line by user inputs on the space.
• Telecordia LSI demo
- Latent Semantic Indexing (LSI) demo by Telecordia Technologies

9. Web IR and Other Modern Problems of Information Retrieval

• Search Engine Tutorial
- Tutorial for understanding how to assemble queries, beginning with identifying the main concepts you are searching for. Overview of search engines is included.

10. User Interface and Visualization

• Amazon Browser
- Link map browser based on Amazon book search results
• Google Browser
- Link map browser based on Google search results
• KartOO
- KartOO is a metasearch engine with visual display interfaces
• Lighthouse
- A document clustering and visualization system.
• Lighthouse Demo
- Lighthouse online demo. This demo shows a sample test collection and query visualization. "Google cache" and "salsa".
• WebVIBE
- webVIBE is the Java version of VIBE. The VIBE system achieves a virtual document space by letting the user establish a coordinate system defined by points of interest (POIs) on the display.
