1. A method for providing information to a user relating to a point-of-interest (POI), the method comprising:
receiving a query via a communication network retrieving, using a processor,
information from a data storage relating to at least one POI based on the received query, wherein the retrieved information comprises a set of retrieved POI tips relating to factual information of the at least one POI, each of the set of retrieved POI tips being previously extracted using a natural language processing model from POI free-text reviews associated with one or more input words, which are reviews of POIs provided in a free-text structure, and respectively associated in the data storage with one or more semantic categories based on a predefined tip ontology, where (i) each extracted POI tip is associated with an occurrence of an identified tip in the corresponding POI free-text review using the natural language processing model and the identified tip's association with the at least one semantic category; and (ii) each semantic category of the predefined tip ontology organizes POI tips by type and is associated with a prediction score generated by a tip identifier model based on the one or more input words of the corresponding POI free-text review; generating, using the processor, a user interface interactively displaying the retrieved POI tips and the semantic categories associated with each of the retrieved POI tips, wherein the displayed POI tips are sorted by their associated displayed semantic categories; and transmitting the generated user interface to a computing device of the user via the communication network for display on the computing device.
