A novel framework for aspect-based opinion classification for tourist places

Tourists want to know the good and bad aspects before going to tourist place of a city or country. Often they search in social network websites to read previous visitors opinions. The tourism industry in any location is highly dependent on previous visitors opinions and their perceptions. However, due to the large amount of available opinion text, tourists are often overwhelmed with information. As a consequence, tourists find it extremely difficult to obtain useful opinions to make a decision about destinations, accommodation, restaurants, tours, and attractions. Opinion mining is a type of natural language processing for tracking the mood of the public about a particular tourist place. Opinion mining involves building a system to collect and categorize opinions about a tourist place. In this paper, analysis on methods of three different types of opinion mining techniques i.e. trend based opinion mining, aspect based opinion mining, and sentence based opinion mining has performed that extracted meaningful information from tweets, reviews and travel blogs. This paper identified the limitations that trends classification methods do not classify the ambiguous trends, data integrity disturbs opinion mining and aspect extraction methods cannot identify the aspects co-reference in opinion sentences. We proposed an aspect-based opinion classification framework for tourism that addresses these limitations. The proposed framework collects data from twitter, extracts the tangible aspects and trends then classifies the trends into positive and negative trends and identifies that which tweet has positive sentiment and which tweet has negative sentiment of aspects.
