  4. Knowledge Management: Overview

  5. Knowledge Management Overview What is Knowledge Management Data, Information, and Knowledge Why Knowledge Management? Knowledge Management Processes

  6. Data: 1980s Factual Structured, numeric Oracle, Sybase, DB2 Information: 1990s Factual Yahoo!, Excalibur, Unstructured, textual Verity, Documentum Knowledge: 2000s Inferential, sensemaking, decision making Multimedia ??? Unit of Analysis

  7. According to Alter (1996), Tobin (1996), and Beckman (1999): Data: Facts, images, or sounds (+interpretation+meaning =) Information: Formatted, filtered, and summarized data (+action+application =) Knowledge: Instincts, ideas, rules, and procedures that guide actions and decisions Data, Information and Knowledge:

  8. Ontologies, hierarchies, and subject headings Knowledge management systems and practices: knowledge maps Digital libraries, search engines, web mining, text mining, data mining, CRM, eCommerce Semantic web, multilingual web, multimedia web, and wireless web Application and Societal Relevance :

  36. Structured Manual Human-driven Unstructured System-aided Data/Info-driven Two Approaches to Codify Knowledge Top-Down Approach Bottom-Up Approach

  37. Knowledge Management Related Field: Search Engine (Source: Jan Peterson and William Chang, Excite)

  38. Basic Architectures: Search Log 20M queries/day Spider Web SE Spam Index SE Browser SE Freshness 24x7 Quality results 800M pages?

  39. Basic Architectures: Directory Url submission Surfing Ontology Web SE Browser SE SE Reviewed Urls

  40. Web HTML data Hyperlinked Directed, disconnected graph Dynamic and static data Estimated 2 billion indexible pages Freshness How often are pages revisited? Spidering

  41. Size from 50M to 150M to 3B urls 50 to 100% indexing overhead 200 to 400GB indices Representation Fields, meta-tags and content NLP: stemming? Indexing

  42. Augmented Vector-space Ranked results with Boolean filtering Quality-based re-ranking Based on hyperlink data or user behavior Spam Manipulation of content to improve placement Search

  43. Short expressions of information need 2.3 words on average Relevance overload is a key issue Users typically only view top results Search is a high volume business Yahoo! 50M queries/day Excite 30M queries/day Infoseek 15M queries/day Queries

  44. Alta Vista: within site search, machine translation

  45. Manual categorization and rating Labor intensive 20 to 50 editors High quality, but low coverage 200-500K urls Browsable ontology Open Directory is a distributed solution Directory

  46. Yahoo: manual ontology (200 ontologists)

  47. Search Engine Watch www.searchenginewatch.com “Analysis of a Very Large Alta Vista Query Log”; Silverstein et al. www.research.digital.com/SRC “The Anatomy of a Large-Scale Hypertextual Web Search Engine”; Brin and Page google.stanford.edu/long321.htm WWW conferences: www13.org Web Resources

  48. Newswire Newsgroups Specialized services (Deja) Information extraction Shopping catalog Events; recipes, etc. Special Collections

  49. Non-indexible content Behind passwords, firewalls Dynamic content Often searchable through local interface Network of distributed search resources How to access? Ask Jeeves! The Hidden Web

  50. Manipulation of content to affect ranking Bogus meta tags Hidden text Jump pages tuned for each search engine Add Url is a spammer’s tool 99% of submissions are spam It’s an arms race Spam
