2. Introduction: In order to define specification for conditions or Intentions Asbru's elements within the semi-formal phase, a need was raised for developing an infrastructure for supporting the work of QA and application tasks of those expressions. This infrastructure will include an user interface and output of the conditions specification which based on xml. Therefore, an Expression-Builder (EB) will be developed and will be integrated as part of URUZ3.

3. Expressions Types: The EB will support 4 main types of conditions in QA model context: Yes/No(Default)- one simple condition with true/false outcome. k from n -(k and n must be numbers)-several N condition,which at least K from them must be true. (a private case is "OR" expression(1 of N)). weights-each condition has relative weight(for intention specification). logical expression (And/Or Tree).-several conditions with boolean logics between them.For example,consider this conditions specification: (1) patients with hypertension who become pregnant AND (2) patients who develop hypertensive disorders during gestation

4. Flow of knowledge A medical expert relates portions of text from the guideline into specific knowledge role using URUZ3 Thus, the text of a guideline converted into structured text. This is in fact, the first phase of structurning
