  1. A User Study on Mathematical Information Retrieval (MIR) By Zhao Jin

  2. Outline • Introduction & Motivation • Findings from the Study • Projected Directions for Future Research • Future Work • Conclusion

  3. Introduction & Motivation • Rapid Growth of Math Material Collection • Mature of Mathematical Expression Recognition Technology • Prevalence of Math Authoring Tools • How to effectively search through such collections? • Additional Medium: Mathematical Expressions • Traditional Text Retrieval Technique may not be applicable

  4. Introduction & Motivation • Limited literature in the domain • Two workshop so far • Few papers and working systems • Focus on supporting searching for mathematical expressions • Is this the correct focus? • User study in MIR • Interviews with students/professors in the Math department

  5. Findings from the Study • The Current Approaches for Searching • The Users’ Needs • The Available Resources

  6. The Current Approaches for Searching • Keyword Search • Fast & Available • Inaccurate, Disorganized, Prior Knowledge Required • Browsing • Highly organized, Digested • Time-consuming • Consulting an Expert • Effective • Not always available

  7. The Users’ needs • Information need • For Learning/Teaching • Definition, Exact form, Variations, Derivation, Explanation, Slides, Tutorial… • For Research • Papers • System Requirement • Accuracy • Expression input not essential

  8. The Available Resources • Web • Huge but disorganized • Keyword search • Book/Paper Collections • Categorized documents • Browsing and controlled access points • Encyclopedia • Categorized information • Browsing and keyword Search • Experts • Intelligent • Question in Natural Language

  9. Projected Directions for Future Research • Collect information from multiple resources • Categorize and present information in a organized manner • Determine the relevance between • Two Mathematical Expressions • Text and Mathematical Expression

  10. Future Work • More Interview • Conference Submission • Corpus Collection • Experiment

  11. Conclusion • User Study on MIR • Findings from the Study • The Current Approaches • The Users’ Needs • The Available Resources • Projected Directions for Future Research • Future Work
