10 Reasons Search Is Difficult

  1. 1. 10 Reasons Search is Difficult Marlene Krempasky
  2. 2. Why is Search so Difficult? <ul><li>Access - content is stored in many locations </li></ul><ul><li>Volume of content </li></ul><ul><li>Diversity of content </li></ul><ul><li>Organization of content is subjective </li></ul><ul><li>Language is ambiguous </li></ul><ul><li>Complex goals – Relevance, Precision, Recall </li></ul><ul><li>Multiple stakeholders –MMD, MRL, GHH, Corporate </li></ul><ul><li>Multidisciplinary teams – functional, departmental therapeutic area, product, project, etc </li></ul><ul><li>Inconsistent or nonexistent metadata </li></ul><ul><li>Lack of content authoring processes </li></ul>
  3. 3. 10 Reasons Search is Difficult Ensure that high value information is stored in an easily searchable repository. Provide a search capability that functions across repositories and creates a central, unified index. This approach leverages existing technologies and avoids the cost of moving/ consolidating data. If content is not stored in an easily searchable location, it can not be leveraged across the enterprise. <ul><li>1) Access to content </li></ul><ul><li>Content is stored in many different locations: </li></ul><ul><ul><li>email </li></ul></ul><ul><ul><li>hard drives </li></ul></ul><ul><ul><li>shared drives </li></ul></ul><ul><ul><li>eRooms </li></ul></ul><ul><ul><li>teamsites </li></ul></ul><ul><ul><li>formal repositories </li></ul></ul>Solution Implication Problem
  4. 4. 10 Reasons Search is Difficult Faceted search results. Provide an easy way to refine search results based on categories (ie., navigators). Search results are overwhelming. Difficult to find relevant content. Information overload. 2) Volume of content The sheer volume of content scattered across the enterprise is massive (eg., a MKN search of a broad topic such as diabetes returns > 200,000 hits!) Solution Implication Problem
  5. 5. 10 Reasons Search is Difficult Taxonomy for all content types. Governance (SOPs for capturing tacit knowledge). Host systems may not be designed to handle and extract value from all content types. <ul><li>3) Diversity of content </li></ul><ul><li>File types (documents, slides, images, notes, videos, etc) </li></ul><ul><li>Structured vs unstructured </li></ul><ul><li>Explicit vs tacit </li></ul>Solution Implication Problem
  6. 6. 10 Reasons Search is Difficult Taxonomy (Controlled vocabularies for picklists to tag content, search dictionaries for synonyms) Apply contextual information solutions (natural language processing, business rules and ontologies to discover the true meaning of the inquiry) Personas The results contains content that is syntactically accurate (ie, keyword matches), but the result may not be useful . Search returns a huge results list with many irrelevant documents. <ul><li>4) Language is ambiguous </li></ul><ul><li>A term may have more than one meaning depending on the context For example the term, “solution”… </li></ul><ul><li>MRL Scientist – a liquid mixture of 2 or more substances </li></ul><ul><li>IT Professional – fix to a help desk reported problem </li></ul><ul><li>Marketing – customer response </li></ul>Solution Implication Problem
  7. 7. 10 Reasons Search is Difficult Governance of a common enterprise-wide information architecture. Development of core metadata fields/ navigators for consistency. Results will be difficult to navigate and/or refine when searching across repositories. <ul><li>5) Organization of content is subjective </li></ul><ul><li>Inconsistent organization of content across the enterprise. </li></ul>Solution Implication Problem
  8. 8. 10 Reasons Search is Difficult Taxonomy that aligns meaning with keywords (ie., a robust metadata tagging system). Inability to meet the business objective of all search queries. 6) Complex goals Users may perform different types of searches: Sample search – introductory sampling of the types & number of documents about a topic (relevance, the most useful & usable content) Existence search – looking for a known item (precision, the ability to retrieve only relevant content, is most important) Exhaustive search – need all of the relevant documents about a topic (recall, ability to retrieve all relevant content, is most important) Solution Implication Problem
  9. 9. 10 Reasons Search is Difficult Governance Increased complexity of knowledge management. <ul><li>7) Multiple stakeholders </li></ul><ul><ul><li>MMD </li></ul></ul><ul><ul><li>MRL </li></ul></ul><ul><ul><li>GHH </li></ul></ul><ul><ul><li>Corporate </li></ul></ul><ul><li>Stakeholders have different business objectives that may influence many aspects of knowledge management. </li></ul>Solution Implication Problem
  10. 10. 10 Reasons Search is Difficult Governance Increased complexity of knowledge management. <ul><li>8) Multidisciplinary teams with different business objectives </li></ul><ul><ul><li>functional </li></ul></ul><ul><ul><li>departmental </li></ul></ul><ul><ul><li>therapeutic area </li></ul></ul><ul><ul><li>product </li></ul></ul><ul><ul><li>project </li></ul></ul>Solution Implication Problem
  11. 11. 10 Reasons Search is Difficult Search dictionaries Governance of core metadata fields and values Consistent content authoring processes Search may not find any relevant content if the correct term is not used in the query. Inconsistent metadata makes navigating or filtering search results difficult. Lack of metadata effects the relevancy ranking of search results and may result in missing key content. <ul><li>9) Inconsistent or nonexistent metadata </li></ul><ul><li>There may be multiple synonyms for any given term. For example, product names evolve across the lifecycle of a product: </li></ul><ul><ul><li>L-number </li></ul></ul><ul><ul><li>MK-number </li></ul></ul><ul><ul><li>Generic name </li></ul></ul><ul><ul><li>Multiple Brand names globally </li></ul></ul>Solution Implication Problem
  12. 12. 10 Reasons Search is Difficult Governance (SOPs for content authoring) Content is not stored in searchable locations. Content is not tagged with consistent metadata . 10) Lack of consistent processes for content authors Solution Implication Problem
  13. 13. Content authoring Language is ambiguous Organization of content Volume of content is subjective Access Large results sets Difficult to navigate (↓ relevancy) or filter results Inconsistent Multiple Metadata Stakeholders Diversity of content Complex goals Implications of not finding content / information Poor business decisions Missed opportunities Increased operating costs Duplication of effort Time spent searching Decreased Findability
  14. 14. Search Optimization: Breadth of Business Impact <ul><li>An effective search solution enables knowledge workers to consistently realize the full potential of information assets across the enterprise. </li></ul><ul><ul><li>Increases productivity* </li></ul></ul><ul><ul><ul><li>Knowledge workers spend less time searching and more time on other tasks (even if a small fraction of time searching for information is decreased, the increase in productivity pays off the search solution very quickly). </li></ul></ul></ul><ul><ul><li>Increases efficiency* </li></ul></ul><ul><ul><ul><li>Leaders have the information they need to make informed and therefore better business decisions faster </li></ul></ul></ul><ul><ul><li>Improved customer relationships </li></ul></ul><ul><ul><ul><li>Enterprise access and utilization of information re: customer needs, preferences, and behaviors </li></ul></ul></ul><ul><ul><li>Mitigates risk of compliance and regulation issues </li></ul></ul>*An Accenture survey found that knowledge workers spend ~ 20% of their time looking for, not finding, and re-creating information.
