Abstract of master's work: «Development of the information providing for implementation of real estate estimation»


          Theme urgency. Changes, which have a place in Ukraine and connected with process of development of the market of ground and real estate, and also expansion of process of a privatization of grounds demand acceptance of urgent measures in a direction of perfection the ways of management of the data of the market of ground and real estate, and also their use with the purposes of estimation of cost of property. The given circumstances cause necessity in formation of the adequate information-methodical base allowing participants of the market in more of degree to use modern information technologies in the field of the market of the ground and real estate properties. One of effective mechanisms of the decision of this problem is introduction universal complex of information the maintenance based on application the Internet of decisions, databases, geoinformation technology and methods of the statistical analysis of data.

           Such supply with information, will allow to provide sphere of an estimation of real estate necessary with the qualitative actual information, to receive is proved-settlement demonstrative result of an estimation and appreciably to raise quality of estimated works, having reduced to a minimum subjective assumptions the appraiser and also to accompany principles of objective data presentation of the market of the ground and real estate.

          The considerable contribution to area of working out and application of methods of the statistical analysis of data, and also in a scope of methods of geoinformation technologies in sphere of estimation of cost it is domestic and foreign scientists have brought. Among them B.A.Semenenko [1], S.A.Sivets [2], J. K.Ekkert [3], S.V.Gribovsky [4], L.D.Bashirova [5], E.N.Ivanov, Д.С.

          Workings out of the Ukrainian and foreign experts, and also modern achievements in sphere of information, geoinformation technologies and methodical maintenance of an estimation of the real estate create all the preconditions for introduction of the universal complex supply with information intended to or performance of estimation of cost of the real estate and also to make following conclusions in essence investigated directions:

          Prompt development of a network the Internet has given access to the most actual sources of the information in real estate sphere. However insufficient level of automation the Internet of sites leaves is defined the marks on quality of the information. These are grammatical errors which are supposed in process entering information in information sources, and also the incomplete information on the subject, bringing the given information. All it does a source of the information and the information unreliable.

          Being based on the aforesaid, it will be fair to make following conclusions:

  • there is an obvious necessity for the effective mechanism of gathering, storage and data presentation;

  • the difficulties connected with absence of qualitative information sources and, accordingly, of reliability and qualitative information, impose certain restrictions on application of those or others estimation methods;

  • the application question in daily practice of methods of the analysis of data of the market real estate is actual, allowing to reduce level of subjectivity of the appraiser and, accordingly.

          Thus, the question of working out and improvement of a supply with information for performance real estate estimations is actual.
