Overview Introduction Related Work Implementation on Basic Facet Search Extended multifaceted Search To Business Intelligence Correlated Facets Pros & Cons Conclusion

INTRODUCTION What’s Faceted Search? Typical user interaction with Faceted Search 1. Type or refine a search query 2. Navigate through multiple search query

INTRODUCTION Shortcoming 1. Should have richer insight into data 2. Too many independent facet hierarchies.

Related Work Multifaceted Search 1. Faceted Hierarchies 2. Mapping the documents OLAP- On Line Analytical Processing CUBE

Implementation of Basic Faceted Search Lucene Document Ingestion 1. Taxonomy before indexing 2. Taxonomy while indexing

Implementation of Basic Faceted Search

Faceted query and Faceted result set FQ=(qc, TF) TF={tf1, tf2,….tfk} tfi=(Pi,ni) n>=1

Extending Multifaceted Search to bussiness intelligence

Dynamic Facets

Correlated Facets

Shortcoming 1. Large index size 2. Difficulty on aggregating counts

Correlated Facets

Pros and cons Dynamic corpora Less complexity Allow multiple sub categories

Conclusion Extended the Basic Faceted Search. 1. Flexible, Dynamic, Business intelligence aggregation 2. Efficiently support correlated facets.
