1. Enterprise & Intranet Search How Enterprise is different from Web search What to think about when evaluating Enterprise Search How Intranet use is different from Web use - And what that means for search

2. Intranet Differences Intranet = content inside the organization Learning from content, not for commerce Smaller content collections - Smaller content subjects - Smaller number of possible tasks or queries More document types than the Web (supports) Filtering could be more applicable Taxonomies may be present (& understandable) - Work groups, locations, departments, projects Content managed in some way (culture or policy) Is the goal to discover tacit knowledge?

3. Differences in Intranet use Bandwidth - Wireless too Security - Financial work, Access policies New technology - Mobile, high-resolution displays, … Legal - Regulation (Sarbanes Oxley) - Privacy Cultural - Adoption - Revolution

4. One week of corporate search What are the patterns of search in a corporation? - Big company 70K - 740K documents 80% HTML, ~15% PDF - Ultraseek engine 11-15 minute search sessions Small drop in Friday searching 71% of the 5644 users only active on one work-week day User sessions - 1.2 w 2.47 activities = infrequent - 3.03 w 9.7 activities/day = frequent What interfaces & tools could increase use? - Is increased searching a net good for knowledge workers?

5. Is Enterprise IR different? Application Design - Webify – Front Ends - Web Services - Application Service Providing - (More) Database Integration (Even More) Integration Issues - Content (CMS and Politics) - Quality & Quantity Existing Design Guidelines More Specific Users - One corporation - The accounting department More Definable Goals - Dictated by management - Interaction with (all?) potential users Must Use - Use Data - Feedback for Verification

6. Enterprise Search Centralized & Measurable - More Return on Investment Work tasks Easier to develop than Web-wide search Clarified - Consistent - Accurate Simplified Technology Platform - More Open to Information Sharing - IA Structures Help Define Organization (Goals) Extendable IA System

7. Intranet Search & Info Extraction Building a system specifically for knowledge workers, vertical markets & types of users Do you think intranet search is different? IT workers spend 15-35% of work time searching for information We need more than relevance as a measure of specific tasks - Question Answering: specific answers, not keyword matching - Categorizing user needs By user? Department? Job? Task? Satisficing results vs. the right answers

8. Information Desk Tasks - Term definitions - Homepages for (internal) groups or topics - Experts - Employee contact (personal) info Categorization of need - Query text itself - Resulting documents - Selected documents Developed a hierarchy

9. Catergories of Search Needs

10. Analysis of Search Needs Query logs - Information & navigational needs - Home pages & Relevance (content) Survey - How to’s & Downloads - Technologies, products, services, groups, projects, people More in-depth analysis possible (logs, more questionnaire surveys) How different are these needs from Web search?

11. Challenges in Enterprise Search Google (Web) is the worst enemy of Enterprise search Content complexity: dbms, non-linked docs, email, CMS content, access levels, servers/locations Ranking becomes more difficult with different document types, metadata, systems Do we need Enterprise Metasearch? - Enterprise, Federated, Web content ++ ? - Corporate Web site, intranet, email, company directory, forms, templates, reports…

12. Key IR research for Enterprises Defining an appropriate enterprise search test collection Effective ranking over heterogeneous collections that a characteristic of enterprise environments Portals for knowledge workers (intranet & internet?) Email search PageRank, relevance measures for internal documents Understanding search context Future considerations for linked, internal media Multimedia* Web 2.0 features & document types* Crawling & updating strategies*

13. Solutions to Enterprise IR Designing linking mechanisms - Based on use or (user generated) metadata - Derive metadata & evaluate automation (e.g. email) Navigation in intranets (saves searching) APIs & open access Part of records management activities Intense focus on user evaluation & development cycles

14. Final Projects & Papers Use class readings for prove your points Be daring with your ideas & state why you think they’re right or interesting Cite any non-obvious facts Proof read you writing Be conscious of writing style & grammar Use APA or ACM style guidelines This should be a good contribution to your portfolio of graduate work.
