Definitions Knowledge Management
4
Collexis definitions on KM Data “Structured data” (data, stored set of a meaningful combination of characters and symbols) Information “Data with ADDED value for the receiver” Knowledge “Combined information and experience in the minds of people” “Knowing how to act to retrieve optimal added value” Competence Combination of Knowledge, skills and behavior that leads to an essential contribution to achieving the goals of the business
5
Collexis definitions on KM Knowledge management: “Creating an enviornment in wich knowledge will retrieve maximum added value” “Actions and Rules based on a consistent strategy witch enables an organisation and her employees to use the available knowledge as a strategic production factor for optimal performance.”
6
Forms of Knowledge To perform ‘Knowledge Management’ one needs to know what forms of Knowledge are there.
7
‘Forms’ of Knowledge Explicit Knowledge –Stored, Transferable Knowledge. –Handbooks, Information Systems, Procedures, etc. –Information Tacit (implicit) Knowledge –In peoples minds –Improved by experience –Not stored, hard to store
8
Knowledge transformation Tacit Explicit From To Social Internal External Combine Copy by seeing Imitate Master-student Report Visualize Modelling Merge Recombine & systemize Learn by doing
9
Collexis definitions on KM Thus: Knowledge is not manageable Only the circumstances in which Knowledge can be explored best are manageable Only explicit knowledge can be stored Implicit knowledge can be made accessible ► Collexis facilitates the optimum circumstances to explore and develop knowledge.
10
The Knowledge infrastructure To find out where Collexis can be of use, we must explore the Knowledge infrastructure
11
Knowledge infrastructure Structure & processes IT ManagementCulture Knowledge flow Develop Share Use Evaluate

Collexis & Knowledge management Collexis facilitates: Retrieving information (portals, search and retrieval) Merging information to support Knowledge processes (dynamic categorization, heat maps, content graphs, etc.) Access knowledge by identifying experts (expert finder) Analyzing information to retrieve knowledge (semantic web) Information mining (semantic web, heat maps, content graphs) ►How ?

21
Collexis Why it was created and how it works
22
One Million Hit Syndrome Billions of gigabytes of information is available Is this bad news or good news? How to manage? –Human indexing is too expensive –Automatic indexing is usually not advanced enough –Keyword search provides too little or too much
23
Information Abundance Increasing amount of digital information in organizations Stored in different forms and different formats Spread over a variety of databases and archives Internet adds staggering volumes of information
24
The Human Touch Store Explicit Knowledge in (relational) thesauri Use free texts and content relations Explore and use linguistic techniques Searching for documents or knowledge? –Knowledge is embedded in people –Collexis behaves like a (human) expert –Collexis finds information, experts and organizations –Collexis supports knowledge exploration
25
The power of Fingerprints Collexis is based on the principle of Fingerprinting Fingerprint: a profile of a piece of information A Fingerprint contains a list of weighted concepts Concepts are derived from a Thesaurus Fingerprint characteristics: unique and small 100% Malaria 35% Agencies 30% Enthusiastic 28% Collaboration 27% Funding 27% Africa 25% Science 15% Dedications 15% Applaud 15% agenda 14% Inaccurate 14% advocacy 13% hope 13% research funding 13% Fund Raising
26
What is a thesaurus? A thesaurus is a specialized vocabulary (“repository of knowledge”) of a particular domain, such as medicine, energy or ICT. It contains selected words, terms and concepts with their semantic relations in a hierarchical structure and can also contain synonyms What is a thesaurus? Aircraft Airplane Means of transport Means of transport Train Automobile Car Truck Lorry Motor Vehicle Plane Simplified Thesaurus example
27
Collexis ®, the concept Word-based Searching What? Why? How? Who? indexing Concept matching
28
The magic of Fingerprinting content fingerprints Jobs CV’s, Skills Articles books Emails Word RFP’s people fingerprints average organization fingerprints average
29
Concept Fingerprints Free text Fingerprints Query text or document Multi concept & free text + Σ MATCH Result list
30
Collexis characteristics Accurate and sensitive Collexis Fingerprints are highly sensitive and accurate, and can be manipulated to optimize search results –Precision: only relevant documents shown –Recall: all relevant documents shown, even when narrowing the search Performance even in millions of documents, search results should be provided instantly Human approach not only documents, but also experts and organizations can be the result of a search
31
Collexis characteristics Open architecture Easy integration by the use of an API Omnivore Collexis processes structured and unstructured information; this is possible in one action Adaptable Collexis respects existing databases and does not require large hardware investments Fast in any language & language independent Collexis works across languages.
32
Some Collexis markets and applications Publishing (portals) Scientific organizations (Referee finder) Biotechnology (Genes and protein identification) Pharmaceutical & Chemical (Research and development) Library (Research) Healthcare (Intranet) Legislation & Jurisdiction (Legal Intelligence) Universities (Research and Portals) International Authorities (Information Mining)
