semantic knowledge management


The need for semantics

• Knowledge workers overwhelmed by info• from intranets, emails, newslines …• but still lack vital information

• 80% of corporate data is unstructured• including key business decisions• subject to regulation, e.g. SOX

• Companies suffer from• decisions made under incomplete knowledge • threat of compliance failure


We need information …

• Identified by semantics, not just keywords• precise and complete

• Selected by their interests & task context• defined semantically

• From heterogeneous sources, • accessed uniformally

• Presented meaningfully• and appropriately for the user


In the right form

• Integrated• into the desktop applications

• Seamless• proactive, not reactive

• Depending on context• interests and current activities• mobile phone, PDA, blackberry

• With appropriate visualisation• relation between documents & concepts

• And expressed in natural language• where this aids understanding• multilingual

the need for semantics


Semantic knowledge management

Semantic knowledge management classifies, finds, distributes, shares and uses

knowledge based on meaning not the particular words used to

represent meaning.


In three words

Semantic knowledge management classifies, finds, distributes, shares and uses

knowledge based on meaning not the particular words used to

represent meaning.



Words and meanings

same word, different meanings

different words, same meaningdisability legislation

equal opportunity laws

different words, related meaning

trade unioncharitycompany

organisation

Jaguar



The SEKT solution

• Finding and sharing knowledge through its semantics• for improved precision and recall• for the user’s interests and current context

• Extracting knowledge• in a meaningful way, without duplication• to create a knowledgebase

• Reasoning about knowledge• Displaying all relevant knowledge

• information-centric, not document-centric


Extracting the semantics

• Information extraction• using human language technology

• Knowledge discovery• machine learning and statistical methods

• Existing metadata, e.g. database schemas• mapping and merging
