Semantic heterogeneity and factors

I was thinking to write about semantic heterogeneity for a long time. Its big problem for semantic matching purpose. Since my thesis on matching between two controlled vocabulary.

In short , I found some factors for heterogeneity problem:

• Time (Vocabulary changes time-to-time)
• place( after 50 miles , a new language starts, for example , italian langauge of trentino people is different than bolzano people or Distinct language in india for every states).
• cultural diversity( English people say centre , American people say center).
• structure of vocabulary (there is no unique presentation of vocabulary, for example some people use rdf files , some people use xml files)

Heterogeneity problem

• Syntactic heterogeneity
• Terminological heterogeneity(Paper vs Article)
• Conceptual heterogeneity is also called semantic heterogeneity.
  
• Semiotic heterogeneity
