Abstract [en]

This thesis considers the problems associated with searches in insufficiently geographically tagged data. The thesis was carried out at Booli Search Technologies AB, a company developing a search engine for the Swedish real estate market.

The aim of the thesis is to identify some areas of possible improvements of the company’s existing technical platform, perform a benchmarking among similar services, suggest possible solutions and lastly, build a prototype from one of the suggested solutions.

The thesis starts out with defining the problems that the search engine faces: some areas are not possible to perform searches on, the users are not presented with the full search result that they expect, some results are placed incorrectly on the map associated with the search results and results are also not described with enough geographical information. These problems are due to the fact that the data retrieved at the indexing stage in the company’s information retrieval process are insufficient and incomplete.

As a result of a benchmarking process and after discussing the results, severalinteresting solutions were identified. A prototype was built on one solution, where polygons are defined and tied to areas, and by looking in which of those polygons a certain real estate object is positioned the geographical data was complemented. The prototype solved the problems stated in the beginning of the thesis, but the solution had some disadvantages, among them the need to define polygons for every area where the search result is to be improved.
