This text offers findings from a case research of other approachesto the remedy of lacking info. Simulations in accordance with facts from the Los AngelesMammography merchandising in church buildings software (LAMP) led the authors to the followingcautionary conclusions in regards to the therapy of lacking facts: (1) Automatedselection of the imputation version within the use of complete Bayesian a number of imputation canlead to unforeseen bias in coefficients of substantial versions. (2) lower than conditionsthat ensue in real facts, casewise deletion can practice much less good than we have been led toexpect through the present literature. (3) particularly unsophisticated imputations, comparable to suggest imputation and conditional suggest imputation, played higher than the technicalliterature led us to anticipate. (4) To underscore issues (1), (2), and (3), the object concludes that imputation versions are important types, and require a similar cautionwith admire to specificity and calculability.

XML technologies enable managing semi-structured documents and structured data in a uniform way. Hence, it should be possible to mix data and documents in order to build virtual health related documents issued from several sources. 2 Knowledge Representation Future targets of Knowledge Representation and Visualisation are the “representation of complex information for discovery of hypothesis and illustration of results and coherences” .
The complexity and diversity of medical information and knowledge representation goes far beyond the scope of the traditional information sources. A library, for example, does not provide quality rankings of the works in the collection. Because of the greater volume of networked information, Internet users want guidance about where to spend the limited amount of time they have to research a subject. They may need to know the three “best” documents for a given purpose. They want this information without paying the costs of employing humans to critique the myriad of Web sites.
The ever-increasing amount of scientific medical literature available via the internet as well as the countless web pages with health related information for patients necessitate very special tools to achieve specific and precise search results. g. using object-attributevalue triples and standardized terminologies. Standardized, controlled medical terminologies like the ICD-code, SNOMED or MeSH may constitute a starting point for the identification of key words in free text, but are not sufficient to represent the dynamic relationships between different objects, making modifiers and semantic links necessary.
