Grocery Shopping Assistant Using OpenCV
In this paper we present an android mobile application that allows user to keep track of food products and grocery items bought during each grocery shopping along with its nutrient information. This application allows user to get nutrient information of products and grocery by just taking a photo. Product matching is performed using SURF feature detection followed by FLANN feature matching. We extract the table from the nutrient fact table image using concepts of erosion, dilation and contour detection. Classifying the grocery is done using Object Categorization through the concepts of Bag of Words (BOW) and SVM machine learning. This application includes three main subsystems: client (Android), server (Node.js) and image processing (OpenCV)
Deep Cascade Multi-task Learning for Slot Filling in Online Shopping Assistant
Slot filling is a critical task in natural language understanding (NLU) for
dialog systems. State-of-the-art approaches treat it as a sequence labeling
problem and adopt such models as BiLSTM-CRF. While these models work relatively
well on standard benchmark datasets, they face challenges in the context of
E-commerce where the slot labels are more informative and carry richer
expressions. In this work, inspired by the unique structure of E-commerce
knowledge base, we propose a novel multi-task model with cascade and residual
connections, which jointly learns segment tagging, named entity tagging and
slot filling. Experiments show the effectiveness of the proposed cascade and
residual structures. Our model has a 14.6% advantage in F1 score over the
strong baseline methods on a new Chinese E-commerce shopping assistant dataset,
while achieving competitive accuracies on a standard dataset. Furthermore,
online test deployed on such dominant E-commerce platform shows 130%
improvement on accuracy of understanding user utterances. Our model has already
gone into production in the E-commerce platform.Comment: AAAI 201
SHOPPING ASSISTANT MENGGUNAKAN AUGMENTED REALITY BERBASIS ANDROID
Augmented reality merupakan kecerdasan buatan yang dapat dikendalikan secara langsung
oleh pengguna dengan visual 3 dimensi yang dapat dimanfaatkan untuk bisnis. Dalam hal
ini, Toko Segoro Antique dijadikan sebagai tempat penelitian karena semakin banyak macam
barang yang dijual sehingga pemilik toko sering kali kewalahan melayani pembeli.
Diperlukan asisten pembelanjaan yang dapat membantu melayani semua pembeli sekaligus
dengan augmented reality konsumen dapat mengetahui informasi rinci tentang barang secara
cepat. Aplikasi yang dikembangkan berfungsi mengenali barang dan diberi nama Shopping
Asisstant. Metode yang digunakan dalam perancangan aplikasi ini adalah Rational Unified
Process yang biasa digunakan untuk mengembangkan sistem berbasis objek. Shopping
Assistant dapat mengenali secara langsung barang-barang yang ada didalam toko cukup
dengan scan barang menggunakan smartphone. Aplikasi ini menggunakan Vuforia sebagai
software library yang berguna sebagai database sekaligus sistem tracking yang digunakan
saat proses pengenalan barang. Hasilnya dengan augmented reality pengunjung dapat
mengenali barang akan tetapi pada proses pengenalan barang, lingkungan pengenalan harus
sesuai dengan lingkungan pencahayaan saat barang di scan
The Role of Similarity in e-Commerce Interactions: The Case of Online Shopping Assistants
This research proposes that technological artifacts are perceived as social actors, and that users can make personality and behavioral attributions towards them. These formed perceptions interact with the user’s own characteristics in the form of an evaluation of similarity. Using an automated shopping assistant, the study investigates the effects of two types of perceived similarity on a number of dependent variables. The results show that both, perceived personality similarity, as well as perceived behavioral similarity, between the user and the decision aid positively affect users’ evaluations of the technological artifact. Furthermore, the study investigates the role of design characteristics in forming social perceptions about the shopping assistant. The results indicate that design characteristics, namely content, can be used to manifest desired personalities and behaviors, allowing us to compute measures of “actual” similarity, which were found to predict perceived similarity
WishToys : a Web-based electronic shopping assistant featuring voice access
This report describes an electronic shopping assistant specialized in toys. The shopping assistant features two distinct user interfaces. One interface is a web-based graphical user interface (GUI) that fully uses the relatively high bandwidth of the Internet connection, allowing for high resolution and high colour content graphics. The GUI interface offers the full functionality of the shopping assistant. The other interface is a low-bandwidth voice user interface (VUI), offering a reduced set of features and allowing an easy and quick access to pre-selected list of toys for people on the move. The VUI is geared specifically towards mobile use, i.e. for users calling from cell phones
SANIP: Shopping Assistant and Navigation for the visually impaired
The proposed shopping assistant model SANIP is going to help blind persons to
detect hand held objects and also to get a video feedback of the information
retrieved from the detected and recognized objects. The proposed model consists
of three python models i.e. Custom Object Detection, Text Detection and Barcode
detection. For object detection of the hand held object, we have created our
own custom dataset that comprises daily goods such as Parle-G, Tide, and Lays.
Other than that we have also collected images of Cart and Exit signs as it is
essential for any person to use a cart and also notice the exit sign in case of
emergency. For the other 2 models proposed the text and barcode information
retrieved is converted from text to speech and relayed to the Blind person. The
model was used to detect objects that were trained on and was successful in
detecting and recognizing the desired output with a good accuracy and
precision.Comment: 6 pages, 8 figures. arXiv admin note: text overlap with

INVESTIGATING CONSUMERS’ ADOPTION OF INTERACTIVE IN-STORE MOBILE SHOPPING ASSISTANT
With smart phones being deployed widely, interactive in-store Mobile Shopping Assistant (MSA) systems can be considered as an effective way for assisting in-store shopping and can become potentially the pervasive personalized services that both consumers and merchant can trust. However, few studies have focused on investigating the adoption of in-store MSA. Therefore, this study examined the consumers’ attitude and acceptance toward in-store MSA services under the framework of the technology acceptance model (TAM). The findings imply that attitude, perceived ease of use, perceived usefulness, environmental variables, perceived quality of the MSA system, social influence, and user satisfaction are some determinant factors. In addition, significant differences exist between female and male consumers
Supervised Transfer Learning for Product Information Question Answering
Popular e-commerce websites such as Amazon offer community question answering
systems for users to pose product related questions and experienced customers
may provide answers voluntarily. In this paper, we show that the large volume
of existing community question answering data can be beneficial when building a
system for answering questions related to product facts and specifications. Our
experimental results demonstrate that the performance of a model for answering
questions related to products listed in the Home Depot website can be improved
by a large margin via a simple transfer learning technique from an existing
large-scale Amazon community question answering dataset. Transfer learning can
result in an increase of about 10% in accuracy in the experimental setting
where we restrict the size of the data of the target task used for training. As
an application of this work, we integrate the best performing model trained in
this work into a mobile-based shopping assistant and show its usefulness.Comment: 2018 17th IEEE International Conference on Machine Learning and

Shopping Assistant App For People With Visual Impairment: An Acceptance Evaluation
Visual impairment refers to when someone lose part or all of the
ability to see. People with visual impairment has many limitations including the freedom of doing grocery shopping independently. They will have difficulty to read ingredients or dietary information which usually returned in small font letters on the products. This information is deemed important to make informed decision in order to purchase products. Therefore, this research is conducted to investigate the need of grocery shopping assistant app for people with visual impairment and their acceptance level. An empirical investigation method is adapted and data was collected based on Technology Acceptance Model (TAM). The evaluation results indicate that the people with visual impairment positively inclined towards utilizing shopping assistant app caused by the technology is
easy to use and therefore they can obtain benefit from the app, concluding that Perceived Ease of Use is a better indicator for the attitude towards using the shopping assistant app
