Assessment, Implication, and Analysis of Online Consumer Reviews: A Literature Review

The onset of e-marketplace, virtual communities and social networking has appreciated the influential capability of online consumer reviews (OCR) and therefore necessitate conglomeration of the body of knowledge. This article attempts to conceptually cluster academic literature in both management and technical domain. The study follows a framework which broadly clusters management research under two heads: OCR Assessment and OCR Implication (business implication). Parallel technical literature has been reviewed to reconcile methodologies adopted in the analysis of text content on the web, majorly reviews. Text mining through automated tools, algorithmic contribution (dominant majorly in technical stream literature) and manual assessment (derived from the stream of content analysis) has been studied in this review article. Literature survey of both the domains is analyzed to propose possible area for further research. Usage of text analysis methods along with statistical and data mining techniques to analyze review text and utilize the knowledge creation for solving managerial issues can possibly constitute further work.

E-commerce website usability analysis using the association rule mining and machine learning algorithm

The overall effectiveness of a website as an e-commerce platform is influenced by how usable it is. This study aimed to find out if advanced web metrics, derived from Google Analytics software, could be used to evaluate the overall usability of e-commerce sites and identify potential usability issues. It is simple to gather web indicators, but processing and interpretation take time. This data is produced through several digital channels, including mobile. Big data has proven to be very helpful in a variety of online platforms, including social networking and e-commerce websites, etc. The sheer amount of data that needs to be processed and assessed to be useful is one of the main issues with e-commerce today as a result of the digital revolution. Additionally, on social media a crucial growth strategy for e-commerce is the usage of BDA capabilities as a guideline to boost sales and draw clients for suppliers. In this paper, we have used the KMP algorithm-based multivariate pruning method for web-based web index searching and different web analytics algorithm with machine learning classifiers to achieve patterns from transactional data gathered from e-commerce websites. Moreover, through the use of log-based transactional data, the research presented in this paper suggests a new machine learning-based evaluation method for evaluating the usability of e-commerce websites. To identify the underlying relationship between the overall usability of the eLearning system and its predictor factors, three machine learning techniques and multiple linear regressions are used to create prediction models. This strategy will lead the e-commerce industry to an economically profitable stage. This capability can assist a vendor in keeping track of customers and items they have viewed, as well as categorizing how customers use their e-commerce emporium so the vendor can cater to their specific needs. It has been proposed that machine learning models, by offering trustworthy prognoses, can aid in excellent usability. Such models might be incorporated into an online prognostic calculator or tool to help with treatment selection and possibly increase visibility. However, none of these models have been recommended for use in reusability because of concerns about the deployment of machine learning in e-commerce and technical issues. One problem with machine learning science that needs to be solved is explainability. For instance, let us say B is 10 and all the people in our population are even. The hash function’s behavior is not random since only buckets 0, 2, 4, 6, and 8 can be the value of h(x). However, if B = 11, we would find that 1/11th of the even integers is transmitted to each of the 11 buckets. The hash function would work well in this situation

Ανίχνευση συναισθήματος σε δεδομένα κοινωνικών δικτύων μέσω εξόρυξης και ανάλυσης

Διπλωματική εργασία -- Πανεπιστήμιο Μακεδονίας, Θεσσαλονίκη, 2018.Κατά την διάρκεια των τελευταίων ετών, η ευρεία χρήση των μέσων κοινωνικής δικτύωσης έχει οδηγήσει στην ταχεία παραγωγή ενός μεγάλου όγκου δεδομένων, η αξιοποίηση των οποίων παρουσιάζει ιδιαίτερο ενδιαφέρον. Στόχος της παρούσας διπλωματικής εργασίας, είναι να εξετάσει μέσω τεχνικών εξόρυξης και ανάλυσης εάν είναι εφικτό να αποδοθούν στοιχεία συναισθήματος στα δεδομένα αυτά. Για την επίτευξη του στόχου, αναπτύχθηκε με τη χρήση του οικοσυστήματος Hadoop, ένα πρωτότυπο σύστημα το οποίο εστιάζει στην πλατφόρμα του Twitter και θα χρησιμοποιηθεί για να διερευνηθεί η δυνατότητα αναγνώρισης συναισθημάτων σε αναρτήσεις χρηστών. Αρχικά, μελετήθηκε η διεθνής βιβλιογραφία σχετικά με τα ερευνητικά πεδία της εργασίας όπως οι τεχνικές εξόρυξης δεδομένων, τα μέσα κοινωνικής δικτύωσης και η ανάλυση συναισθήματος. Στη συνέχεια, αναπτύχθηκε η μεθοδολογία έρευνας όπου και καταγράφηκαν ο τρόπος ανάπτυξης των αλγορίθμων ανίχνευσης του συναισθήματος και τα κριτήρια αξιολόγησής τους. Προσδιορίστηκαν οι προδιαγραφές τις οποίες θα πρέπει να πληροί το πρωτότυπο σύστημα ώστε να είναι εφικτή η υλοποίηση και αξιολόγηση των αλγορίθμων και αναζητήθηκαν τα κατάλληλα εργαλεία λογισμικού για να υλοποιηθεί. Τα αποτελέσματα της αξιολόγησης του συστήματος επιβεβαιώνουν τον ισχυρισμό, ότι με την χρήση τεχνικών εξόρυξης και ανάλυσης μπορεί να αποδοθεί συναίσθημα σε δεδομένα χρηστών από κοινωνικά δίκτυα
