Social networking app has been growing very rapidly in the past decade. One of the important features of social media is the ability of system that can attach coordinate where users are located (check-in). The aim of this study is to identify the characteristic of human mobility patterns in Bandung city. We proposed a technique uses pixel matching approach. In this paper, we describe the visualization of the city is determined by the activity of people on Twitter social media. Our work includes firstly, characterize the pattern of user’s interest to different types of places. Secondly, to characterize the pattern of user visits to different neighborhoods with way choose the user’s activity pattern on the weekdays and weekends. We then categorize the existing place based on the period of time that people visiting. Meanwhile, to define the existing areas, we used official map the city planning department as parameters to determine the user’s movement. Our research will answer the question whether the Twitter App data is a viable resource to measure the human movement? The result indicates that it can be used as the one of the sources of information data to understand urban human mobility
Location Based Service in Social Media: An Overview of Application Yuyun Wabula
This paper presents a literature review on the use of geolocation data on social media. Geolocation is one of the feature on the social media which utilize the GPS devices embedded in the smartphones, tablets, or computers gadget that can show a user’s location map. This is related to a virtual user activity in the parts of the world, when and where they are. The main objective of this research is to investigate the extent to which spread of articles related to the application of location-based data on social media, such as problem issues, techniques applied, problem solved especially in urban environment context, published from 2010 to 2016. We analyzed 35 references which accordance with this field. The attribute prepared based on the application area, years, and author's parts to simplify the organizing of geolocation data applications. Then, the data format summarized in the tabular form for helping a readers. Authors find that three important issues that we have identified related to this field; distances, locations, and movements. Our research can contribute for the researchers for them future work regarding to the developments and limitations of each articles.
The Shortest Path to Happiness: Recommending Beautiful, Quiet, and Happy Rout...Ludovic Privat
ABSTRACT
When providing directions to a place, web and mobile map-
ping services are all able to suggest the shortest route. The
goal of this work is to automatically suggest routes that are
not only short but also emotionally pleasant. To quantify
the extent to which urban locations are pleasant, we use data
from a crowd-sourcing platform that shows two street scenes
in London (out of hundreds), and a user votes on which one
looks more beautiful, quiet, and happy. We consider votes
from more than 3.3K individuals and translate them into
quantitative measures of location perceptions. We arrange
those locations into a graph upon which we learn pleasant
routes. Based on a quantitative validation, we nd that,
compared to the shortest routes, the recommended ones add
just a few extra walking minutes and are indeed perceived
to be more beautiful, quiet, and happy. To test the gener-
ality of our approach, we consider Flickr metadata of more
than 3.7M pictures in London and 1.3M in Boston, com-
pute proxies for the crowdsourced beauty dimension (the
one for which we have collected the most votes), and evalu-
ate those proxies with 30 participants in London and 54 in
Boston. These participants have not only rated our recom-
mendations but have also carefully motivated their choices,
providing insights for future work.
International Refereed Journal of Engineering and Science (IRJES) is a peer reviewed online journal for professionals and researchers in the field of computer science. The main aim is to resolve emerging and outstanding problems revealed by recent social and technological change.

Understanding the Privacy Implications of Using Context-based Awareness Cues ...Ville Antila
Information from the physical world is increasingly being digitalized and shared in social networks. We share our locations, tag photos and add different kinds of informal awareness cues about the physical world to our online communities. In this paper, we investigate the privacy implications of shared context cues in social networking services. We present an experimental mobile application, which allows users to add different descriptions of context information to their Facebook and Twitter status updates. The application was used by 12 persons during a two-week user trial using their own devices and Facebook accounts. The results indicate that user-defined abstractions of context items were often preferred over more accurate indicators due to privacy concerns or discomfort in sharing. We also found out that using shared context from friends in vicinity needs careful design to overcome the extended privacy implications.

The mining of the user GPS trajectories and identifying the interesting places have been well studied based on the visitor’s frequency. However, every user is given the same importance in the majority of the trajectory mining methods. In reality, the popularity of the place also depends on the category of the visitor i.e. international vs local visitors etc. We are proposing user category based location popularity estimation using the trajectories databases. It includes mainly three steps. First , pre-processing – the error correction and the graph connection establishment in the road network in order to be able to carry the graph based computations. Second , find the stay regions where the travelers spent some time off-the-road. The visitors can be easily categorized for each POI based on the travel distance from the home location. Finally , normalization and popularity estimation – measure the frequency and stay time of the visitors of each category in the places in question.

Large scale geospatial analysis on mobile application usageEricsson
Several studies indicate that mobile usage habits can be affected by the user’s location, such as rural areas and points of interest (schools, airports).
Android Phone has power to access or fetch data from remote location and provide various facilities to the user. Hence android applications have more and more demand because of its user friendly nature and its power of computation. Many tourist are having problem to search proper tourist places due to communication overhead or less facility of tourist guide. It is impractical to search each and every tourist place at every location. So in order to provide feasible as well as user friendly solution for this problem we develop an android application which will automatically recognize famous and nearby places and send notification to android phone. This application also provides weather recommendation feature which notifies the tourist about weather conditions of the destination before visiting it. All places are properly categorized and also with review or rating. The application also provides facility of vehicle mark to reach your vehicle after site visit. We are using Triangulation method with LBS as well as GPS to track the location of user. And as per his location, relevant list of tourist places will be send in the form of pop up notification.

This article sets forth the early phases of a methodological proposal for designing and developing Volunteered Geographic Information (VGI) initiatives based on a system perspective analysis in which the components depend and interact dynamically among each other. First, it focuses on those characteristics of VGI projects that present different goals and modes of organization, while using a crowdsourcing strategy to manage participants and contributions. Next, a tool is developed in order to design the central crowdsourced processing unit that is best suited for a specific project definition, associating it with a trend towards crowd-based or community-driven approaches. The design is structured around the characterization of different ways of participating, and the task cognitive demand of working on geo-information management, spatial problem solving and ideation, or knowledge acquisition. Then, the crowdsourcing process design helps to identify what kind of participants are needed and outline subsequent engagement strategies. This is based on an analysis of differences among volunteers’ participatory behaviors and the associated set of factors motivating them to contribute, whether on a crowd or community-sourced basis. From a VGI system perspective, this paper presents a set of guidelines and methodological steps in order to align project goals, processes and volunteers and thus successfully attract participation. This methodology helps establish the initial requirements for a VGI system, and, in its current state, it mainly focuses on two components of the system: project and participants.

Development of NGO is also development of society prestige, which makes significance contribution to diverse areas. Since NGO are non-profit organization, they always lack resources. Thus, to fulfill the requirements “UNNATI SAMAJ “app will be a rescue. Using this app any donor can donate food, clothes, and other items which can be utilize by needy ones. For e.g. from big organized parties, often food gets wasted, so using the app’s Google API technology people can donate the food to nearest NGO without needed to search up for contact information. Thus, our app will be a direct bridge between all NGOs and donors.

A CROSS-CULTURAL STUDY ON THE VALUE STRUCTURE OF MOBILE INTERNET USAGE: COMPA...Ranti Yulia Wardani
The number of mobile Internet users has been growing rapidly worldwide. Access to the Internet
via mobile cellular networks has also grown rapidly. The effects of different culture of mobile Internet would be interesting to be investigated. The research objective is to investigate the usage pattern differences of mobile Internet users in Indonesia and Japan and to interpret them within the framework of a value structure. The data collection technique used in this study was the survey method. The same questionnaire written in mother language of each country was given to respondents in Japan and Indonesia directly. The result shows that value structures (functional value, emotional value, social value, and monetary value) simultaneously affect the satisfaction of mobile Internet usage of Indonesian respondents, which affect the satisfaction of Japanese respondents. Social value did not
significantly affect the satisfaction of mobile Internet usage of Japanese respondents. The implications of cross-cultural differences of mobile Internet will be discussed in this paper. This paper will be ended with discussion, conclusion with practical implications and limitations.

Abstract: In this paper we present a SOA (Service Oriented Architecture)-based platform, enabling the retrieval and
analysis of big datasets stemming from social networking (SN) sites and Internet of Things (IoT) devices,
collected by smart city applications and socially-aware data aggregation services. A large set of city
applications in the areas of Participating Urbanism, Augmented Reality and Sound-Mapping throughout
participating cities is being applied, resulting into produced sets of millions of user-generated events and
online SN reports fed into the RADICAL platform. Moreover, we study the application of data analytics such
as sentiment analysis to the combined IoT and SN data saved into an SQL database, further investigating
algorithmic and configurations to minimize delays in dataset processing and results retrieval.
1 INTRODUCTION
Modern cities are increasingly turning towards
ICT technology for confronting pressures associated
with demographic changes, urbanization, climate
change (Romero Lankao, 2008) and globalization.
Therefore, most cities have undertaken significant
investments during the last decade in ICT
infrastructure including computers, broadband
connectivity and recently sensing infrastructures.
These infrastructures have empowered a number of
innovative services in areas such as participatory
sensing, urban logistics and ambient assisted living.
Such services have been extensively deployed in
several cities, thereby demonstrating the potential
benefits of ICT infrastructures for businesses and the
citizens themselves. During the last few years we
have also witnessed an explosion of sensor
deployments and social networking services, along
with the emergence of social networking (Conti et al.,
2011) and internet‐of‐things technologies (Perera et
al., 2013; Sundmaeker et al., 2010) Social and sensor

For e.g. from big organized parties, often food gets wasted, so using the app’s Google API technology people can donate the food to nearest NGO without needed to search up for contact information. Thus, our app will be a direct bridge between all NGOs and donors.

A CROSS-CULTURAL STUDY ON THE VALUE STRUCTURE OF MOBILE INTERNET USAGE: COMPA...Ranti Yulia Wardani
The number of mobile Internet users has been growing rapidly worldwide. Access to the Internet
via mobile cellular networks has also grown rapidly. The effects of different culture of mobile Internet would be interesting to be investigated. The research objective is to investigate the usage pattern differences of mobile Internet users in Indonesia and Japan and to interpret them within the framework of a value structure. The data collection technique used in this study was the survey method. The same questionnaire written in mother language of each country was given to respondents in Japan and Indonesia directly. The result shows that value structures (functional value, emotional value, social value, and monetary value) simultaneously affect the satisfaction of mobile Internet usage of Indonesian respondents, which affect the satisfaction of Japanese respondents. Social value did not
significantly affect the satisfaction of mobile Internet usage of Japanese respondents. The implications of cross-cultural differences of mobile Internet will be discussed in this paper. This paper will be ended with discussion, conclusion with practical implications and limitations.

Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Abstract
Social networking app has been growing very rapidly in the past decade. One of the important features of
social media is the ability of system that can attach coordinate where users are located (check-in). The aim of
this study is to identify the characteristic of human mobility patterns in Bandung city. We proposed a
technique uses pixel matching approach. In this paper, we describe the visualization of the city is
determined by the activity of people on Twitter social media. Our work includes firstly, characterize the
pattern of user’s interest to different types of places. Secondly, to characterize the pattern of user visits to
different neighborhoods with way choose the user’s activity pattern on the weekdays and weekends. We then
categorize the existing place based on the period of time that people visiting. Meanwhile, to define the
existing areas, we used official map the city planning department as parameters to determine the user’s
movement. Our research will answer the question whether the Twitter App data is a viable resource to
measure the human movement? The result indicates that it can be used as the one of the sources of
information data to understand urban human mobility.
Keywords: social networking; human mobility; check-in data
1. Introduction
Social media are software tools to create the social
network that allows people to share and exchange
information [1]. Social media word became popular
when the Twitter and Facebook began to be known by
internet users. With the increasing of social
networking application, users are able to express
happiness, pleasure and opinion about what they see of
places visited. One important feature on social media
is the ability to display the location in real time, which
is called geolocation. It does allow people to share the
virtual activity through the mobile device
(smartphones) that can show a location maps
when and where the devices are located. In addition
to location and timing, this data informs us activities
towards specific types of location (e.g. Shop, Parks,
Hotels or other places) that we are visiting. From this
information, we argue that there is an exciting
opportunity for creating new ways to understand
human mobility behaviors. With the result that, we can
infer user’s interaction from their activity location in
different part a city. Currently, a variety of researches
were conducted for implementing the location-based
data, such as recommendation potential places for
marketing or recommendation places to assign tourist
service and determining touristic location based on a
user’s visiting [2, 3, 4, 5]. This data has potential to
provided new opportunities for others science
including urban planning, marketing, industrial and so
on. For that, a great opportunity exists for the
researcher to analyze this large of data that allow one
to understand the social and behavior characteristics of
the people on virtual location.
Currently, analysis of human mobility has become
a new paradigm in which the activity of people can be
monitored directly through social media application.
On the previous approach, there are many ways to
measure the movement of urban citizens. Researcher
have found that human mobility plays vital roles in
human urban development and human migration,
planning urban infrastructures, developing transport
and commuting alternatives [6, 7, 8]. Most of the
research has focused on big cities, the fact that human
mobility increasing are complex in densely populated
areas [6]. The current trend of research on human
mobility focuses on understanding the movement
trajectories of individuals. On the previous approach,
there are many ways to measure the movement of

urban citizens. Such information is usually gathered
through a survey method or using questionnaires that
attempt to capture how the citizens interact with their
environment [9, 10, 11]. But on the other hand, this
approach has some limitation such as the accuracy of
the respondent to answer the questions or usually
costly to implement and it has the weakness to smother
the large number of individuals and some problems of
reliability [12].
On the other hand, some studies using data sets
collected from mobile phone traces as the alternative
to measuring user’s mobility [13, 14], GPS devices,
bank records movement, and subway smartcard notes
[15, 16, 17]. Through those devices, individuals can
spend their majority of time with visited specific
locations. Recently, Mobile phone data have been one
of technology devices which often used to describe
human movement within cities. Because most of the
information derived from mobile phone data provides
information of the location where calls occurred.
However, movement patterns and spatial behaviors of
individuals within cities remains hard to understand,
lack a quantitative validation of the results and
difficult to obtain due to privacy concerns [18, 19].
In the literature, we found some research discussed
about human mobility using geosocial networking data.
Cho et al. [21] used geo-location data on Gowalla and
Brightkite to investigate the human movement. They
developed a model of human mobility that combines
periodic short-range movements with travel due to the
social network structure. In another study, Nouclas et
al. [6] used Foursquare data to study human mobility
and answer the question how to measure the human
movement in different cities. They paper described the
rank-based model to measure users movement.
In this paper, we propose to use the Geolocation
data obtained from social networking check-in to
characteristic urban human mobility. To do this, we
propose a mobility model with pixel matching
approach. This approach is trying to count the number
of visitors in each region by transforming the image
pixel value into GPS (latitude and longitude)
coordinate. Our work consist of two steps (1)
characterizes existing place, to categorize the pattern
of user’s interest to different types of places. In this
step, count the number of visitors on each place for
each category. This activity produces activity maps
showing the functionality of each part within a city. (2)
Time distribution, to divide the pattern of user visits to
the different environment with way choose the users
activity on the weekdays and weekends. Then, we
categorize the existing place based on the period of
time that people visiting.
2. Methodology and Data Collection
2.1 Method.
We characterize each of geo-location Tweets with
matching pixel between the image on the map which is
released by city planning department of Bandung local
government (see figure 4). This model utilizes the
colors feature on the map based on the number of
pixels in each color and then is transformed on the
GPS scale. Determining the location areas is calculated
based on the thickness of pixel colors. As an example,
education area with the pixel 74-71 is located at
coordinate -6.85903, 107.59383 to -6.96792,
107.68094 (see table 1). As for the procedure of
system is as follows:
Fig.1. Flowchart model for data analyze
For each region group Ct, △w range of pixel colors
on certain area and p GPS position on color pixel is
built as:
1. Look for the pixel values of each color △w 0…255
on the map. There are thirteen area categories is
marked by color
2. Used the deviation standard to calculate the
average value of all data points. This function is
used to measuring how far the data values lie from
the mean
3. Each position which is marked by latitude and
longitude coordinate p is transformed into the pixel
value. Matching both of them produce the point or
position in a region. To find the frequency of
visiting place, we rank cells based on the range
value of check-ins for each activity category

Data Collection
One of the Twitter app features allows users to tag
their current location. When a new post is made, it will
record their geographical information by specifying an
area or location in order to find their longitude and
latitude coordinates at that moment. This research is
focused in Bandung city, Indonesia which has an area
of 167, 30 km2
and population density 14,736 km2
with a population 1, 4 million.
For data collection, we utilized Twitter Streaming
Application Program Interface (API). It is a window
that applications provide to developers for accessing
them in a programmatic manner. The REST APIs
provide programmatic access to read and write Twitter
data. As example; Author a new Tweet, read author
profile, follower data, time zone and location
information that indicate where the Tweet is posted
[20]. our final Twitter data set consist of 35 days (five
weeks) is started from August 27th to October 1st. It is
constructed from Indonesian language Tweet, which
was filtered to find those tweets that contain the
geolocation. In this study we analyze 375,410 data
records from Twitter. For further steps, authors only
process data that contain user’s location.
3. Result
To locate the exact location, we match user’s data
position (geo-location) on Twitter with colors feature
that exist on the map. Color depth is measured by pixel
and check-in is marked with location coordinate.
Because the depth of color is very different, so that the
pixel value is also different. To count the number of
visitors (check-in) on the particular area then, the value
of GPS is transformed to pixel scale. In the table below
we can see the value of class for each category.
Meanwhile, colors feature on the map can be seen on
figure 4.
Fig. 2. Frequency distribution of daily activity
To divide the urban land, we group each coordinate
location within the thirteen categories. Each category
represents a set of land function. Determination the
name of categories is based on the map of the planning
department. For analytical purposes, we group
check-in across the city by pixel matching. This
analysis can be used to count the number of users in
each category. From these result, we can determine the
location of each user at the time the Tweet is posted.
3.1 Visitation Frequency
To find the distribution of visiting places, we rank
each individual visited places based on the number of
times one visits the places over the study period. For
example rank 1 represents the most visited category;
rank 2 the second most visited category and so on.
Then we calculate the frequency of each of these
ranked places.

Figure 2 shows frequency distribution of daily
visiting activity. We observe the data distribution is
dominated by home users. Meanwhile, the user’s
activity in places such as work, business and park
categories is running normally. In addition, the home
category that has the highest Tweet, the majorities of
activity also come on Friday, Saturday, and Sunday. If
the user is ranked based on daily activity then, the
tendency of people are at the home category (52, 9%),
Business (19%), Park (16, 7%), work (7, 9%) and
industrial (3, 4%). Furthermore in figure 5, we show
the spread of data in each category. Each area
category displays the density of user activity when
they are check-in specific venue
3.2 Data Distribution
We observe that check-in activity in figure 5 is
comparison during weekdays and weekends. In
average, during weekdays and weekends, highest
tweeting activity is coming at around 20-21AM.
Meanwhile, the peak of the tweeting activity during
the weekends is reduced when compared to weekdays.
We also analyze the weekly rhythm of these visits.
During afternoon highest tweeting activity is reached
at around 18 AM which might be associated to the
time at which people typical get home from work.
And then for night activity is coming at 21 PM. This
activity might be associated to the time at which
people typical visiting the entertainment activities like
bars and night clubs. While weekly patterns suggest
that shopping and recreation trips are predominant in
the weekends. Fig. 3. Check-in density for different categories

Fig. 6. Comparison of user frequency distribution
Based on Figure 5, we found that distribution
pattern of Tweeter activity on weekdays and weekends
is running normally although the number of user
activity has decreased. On table 2, we have shown the
average of visiting in different places. We observe that
there is a significant difference between each of them
Such as the number of the visitor at work and
industrial categories that have increased on weekdays.
We assumed that it is related to the activity of people
at the workplaces while at the weekends has decreased
amount. This is because, they visited places such as the
park, business or stay at home. It can be proved by the
increasing the number of them on weekends.
Table 2. Average of weekdays and weekends period
Area categories Weekdays Weekends
Business 18.6% 19.6%
Work 8.0% 4.8%
Park 15.9% 18.0%
Home 54.0% 55.3%
Industrial 3.4% 2.4%
4. Conclusion
Our paper presented the use of geo-location of
social networking as the one source of data to measure
urban human mobility. In this paper, we introduced the
matching pixel image method. This model utilizes

pixel feature on each color and transformed it on GPS
coordinate. To determine the location areas is
calculated based on the thickness of each color. Our
work is characterizing the pattern of user’s interest to
different types of places and characterize the pattern of
user visits to different neighborhoods. We observed
that data distribution is dominated by home users. Next,
we also observed the distribution of data in weekdays
and weekends. We found significant differences in
each category, such as work and business categories is
dominant on weekdays while business, park, and home
categories on weekends. In addition, the home
category that has the highest Tweet, the majorities of
activity categories also come on Friday, Saturday, and
Sunday. If check-in is ranked based on daily activity
then, the tendency of people is the home category (52,
9%), business (19%), park (16, 7%), work (7, 9%) and
industrial (3, 4%). We believe that using the
geo-location of social networking approach is a new
way to view the shape of the city. Because this study
only shows one city and for future work, we will
compare it with other cities.
