Algorithm 1. Integration of profile supplier information to ubiquitous user model.
Require: U2MIO ontology
Ensure: All the semantic mappings MXi,U, U2MIO enhance recommendations and new instance in U2MIO with profile information
1:	Extract sdi from profile information supplier
2:	Save sdi with a timestamp and source id in the Raw data repository
3:	if source id is new to U2MIO then
4:	create a new concept scheme Xi, identify (Ci, Hi, Vi) and insert an instance with Vi values in U2MIO  comment: Element level matching
5:	Extract CT from the ubiquitous user model concept scheme U
6:	Calculate the relation R0 of every triplet 〈cs, ct, R0〉 ∀cs ∈ CS, ∀ct ∈ CT  comment: Structure level matching
7:	Select the set of neighbors NS, ∀cs ∈ Cs and NT, ∀ctb ∈ CT
8:	Calculate relation R1 of every triplet 〈c′s, c′tb, R1〉 ∀c′s ∈ Ns, ∀c′tb ∈ Nt
9:	Apply IF THEN rules given R0 and R1 ∀cs ∈ Cs and obtain  MXi,U = map (cs, ctb) ∀cs ∈ CS, ∀ctb ∈ CT and U2MIO
10:	Add MXi,U to U2MIO and implement recommendations
11:	else
12:	Update Xi instance with Vi values in U2MIO
13:	end if
