Lecture Notes in Computer Science- P91:This year, we received about 170 submissions to ICWL 2008. There were a total of 52 full papers, representing an acceptance rate of about 30%, plus one invited paper accepted for inclusion in this LNCS proceedings. The authors of these accepted papers | The Design of WBPCLS for Computer Science Courses 439 Table 3. Student A selected courses Course name Course conception items Network programming network software method ACE Network management network hardware management ABG security Distributing System network system management AFG Software Engineering software method management CEG Systems Analysis software database method system CDEF Design Multimedia System software system CF Design Database Management network database management ADG E-Commerce software database method system CDEFG Programming management software system CF Table 4. Student A course conception favor vector favor vector reliability A- G C- E C- F the student A s records shown in the Table 3 in which the item A B C D E F G represent Network hardware software database method system and management respectively. The finally course conception favor vector is formed Table 4 . 3. To comparison and recommendation When the student wants to search for the course that belongs to someone course conception we first turn the course conception favor vector into favor rule vector then compare it with the course vector Table 5 calculate comparison value v using contrast formula Z and finally recommend courses according to the descending order of v value. For example when student A wants to search for the course with course concept C software according to C- E C- F which come from student A course conception favor vector we may deduce out that student A possibly likes the course with the course conception including software method system C E F .The course conception favor vector is turned into favor rule vector 0010110 possibility favor course s vector value sets 1 the others sets 0 and then the favor rule vector is compared with the course vector by using characteristic contrast formula the results were shown in table 5. 1 n V - 1 - x - y I 1 n i - 440 Z. Li and X. Zhao The bigger the v value is the better the corresponding course is
