Summary:
The purpose of this thesis is the creation of a recommendation system which
obtains information from websites that contain user reviews and general
information about London restaurants. The system consists of several
components. The first of these components performs a pre-processing of the data
obtained from the selected websites, after having established the essential
attributes of the restaurants on which the grouping information is based. The
pre-processed information is transformed into metadata through an information
extraction technique, during which natural language processing is held and
labels are placed. The metadata are processed with the help of weighting
factors in order to produce the final results, which are then stored. Then, the
user is able to state at the interface of the recommendations system his
preferences regarding the attributes of the restaurants and the recommendations
that are shown are calculated to correspond the preferences stated. A major
advantage of the system is the fact that the provided recommendations are
independent of the restaurants’ popularity. Nonetheless, the recommendations
depend on the popularity of the reviews and the users.
