Web analytics for offline

By bringing web analytics into the offline world, merchants can analyze shopper visit data and learn about the behavior and movement of customers in their stores. This data can then be used to optimize the shopping experience, grow key customer segments, and measure the impact that mobile campaigns are having on foot traffic in real-time. Here are five hyperlocal vendors bringing web-style analytics into the real world. - see it here

It is what our Spotique is for.

Smart Cities Software: Customized Messages for Mobile Subscribers

Manfred Sneps-Sneppe, Dmitry Namiot "Smart Cities Software: Customized Messages for Mobile Subscribers", Wireless Access Flexibility, Lecture Notes in Computer Science Volume 8072, 2013, pp 25-36

This paper introduces a new way of delivering local messages to mobile subscribers. Our application presents a mashup from passive monitoring for smart phones and cloud-based messaging for mobile operational systems. Passive monitoring can detect the presence of mobile phones without active participation from the users. It does not require prior calibration, nor does it require mobile users to mark their own location on social networks (like traditional check-ins). Mobile users do not need to run location track applications on their phones the. At the same time, a production-based expert system built around cloud messaging allows interested parties to directly deliver their custom information to mobile users in proximity.

One-class SVM

Traditionally, many classification problems try to solve the two or multi-class situation. The goal of the machine learning application is to distinguish test data between a number of classes, using training data. But what if you only have data of one class and the goal is to test new data and found out whether it is alike or not like the training data? A method for this task, which gained much popularity the last two decades, is the One-Class Support Vector Machine

Analysis of trajectories in mobile networks

Our new paper: Analysis of trajectories in mobile networks based on data about the network proximity

This paper is devoted to location-based mobile services. The movement (trajectory) data extraction from logs related to network proximity is considered. Usually, this type of pattern extraction (search) relates to trajectory databases containing geoposition information. We consider a model of context-aware computing (a context-aware browser) based on network proximity. A mobile phone is considered as a proximity sensor. The geoposition information is replaced with the network proximity. Any existing or specially created network node can be regarded as a sensor of presence that provides access to dynamically determined network content. The disclosure of the content depends on the set of rules describing the conditions of network’s proximity. An algorithm is given for calculating the trajectories in mobile networks based on information about the network’s proximity.

Networks Sensors and Social Streams

Our new paper: Wireless Networks Sensors and Social Streams.

The paper introduces a new approach for using wireless sensors on mobile phones for integrating data from social networks. We describe existing models for integrating sensors and social networks, as well as propose a new practical approach for social context-aware data discovery that uses mobile phone as proximity sensor. Our concept uses wireless networks sensors from mobile phones (Wi-Fi, Bluetooth) as presence sensor that can open (discover) access for some content published in the social networks. And an appropriate mobile service (context-aware browser client for social networks) can present that information to mobile subscribers. As the potential use-cases for the proposed approach we can mention all projects related to hyper-local news data. For example, proximity marketing, Smart City news, indoor information delivery, etc.

Smart Metering

Manfred Sneps-Sneppe, Anatoly Maximenko, Dmitry Namiot, "On M2M communications standards for smart metering"

The paper discusses M2M communications standards for smart metering. One of the our goals is to show the failures of ETSI standartization process for M2M communications. Our paper proposes some extesions to ETSI standards. At the first hand, it is M-Bus protocol and Open Metering System based on M-Bus. The paper shows how to estimate wireless M-bus throughput and how to avoid collisions. After analysis of Open API for M2M, submitted to ETSI, we propose a new approach in the client-side web development - Web Intents. The main goal for our suggestions is to simplify the development phase for new applications by support asynchronous calls and JSON versus XML for data exchange.

Presented on The INTHITEN (INternet of THings and ITs ENablers) conference.

PRISM and location sharing

If you want to know just how crazy fear over PRISM-like surveillance has made the Internet, take a look at DuckDuckGo.

DuckDuckGo was launched in 2008 and has since become the foremost search engine for those concerned about not just snooping by the government but Google as well. When visitors search via DuckDuckGo, the search engine doesn’t track them; it just gives them the search results they request. (Like Google, DuckDuckGo does serve contextual ads, which is how it makes its money.) - from here.

PRISM fears are growing. And in this context location sharing is much more important area. So, pay your attention to our WATN approach. It lets you share location info without saving all your data on some centralized (read - PRISM-ed) store. See WATN related info in this blog or our Peer to Peer Location Sharing article, for example.

New pattern for stock prices

New pattern to predict stock prices, multiplies return by factor 5.

Does it work? Positive memory for stock prices: "I looked at the daily performance the following day (again comparing day-to-day close prices), for companies who ranked either #1 or #500 today. Companies that ranked #1 today also experienced (on average) a boost in stock price the next day. The boost was more substantial for companies experiencing a 7.5% (or more) price increase today. And the return boost on the next day was statistically significant, and quite large."

This paper describes a new approach to local messaging. Our application combines passive monitoring for smart phones and cloud based messaging for mobile OS (operational system). Passive monitoring can determine the location of mobile subscribers (mobile phones, actually) without the active participation of the users. Mobile users do not need to mark own location on social networks (check-in), they do not need to run on their phones the location track applications. In the same time, Cloud Messaging allows interested parties to directly deliver their information to mobile users who find themselves near a selected point. This is the main content of the service - how to combine the monitoring and notifications.

It is who, not where, that more strongly impacts CTRs and SVRs. The power of mobile location data lies in extracting context and meaning from historical location patterns to interpret meaningful insights about users; not the fleeting, real-time moment that a consumer enters a geo-fence." - from here

About Group Chats on Twitter

An interesting article from WWW 2013 conference: Group Chats on Twitter.

Authors report on a new kind of group conversation on Twitter they call a group chat. These chats are periodic, synchronized group conversations focused on specific topics and they exist at a massive scale. The groups and the members of these groups are not explicitly known. Rather, members agree on a hashtag and a meeting time to discuss a subject of interest.

Group chats are similar to virtual communities in that the primary venue for communicating is online. As with other communities, the purpose is to exchange knowledge, to share experiences, to provide empathy and generally feel part of a community. Also, groups chats can be sprawled out geographically and thus they en- able a way to meet that would otherwise be difficult or impossible. However, they differ from virtual communities in that they use the Twitter platform as a real-time mechanism to communicate in groups. The real-time nature of these conversations imparts a live feeling that is hard to duplicate in other online venues such as forums. Another key difference is that these groups are implicit and therefore not easily discoverable.

In this connection we would like to point attention to our Twicus application. Actually, this application creates Group Chats on Twitter. One of the obvious applied areas is the second screen application for discussing TV show.

Bayesian Way for ranking comments

The most simple, and most popular, form of moderation of cooments is to rank according to a simple difference, score = #upvotes - #downvotes. However, this scoring function significantly over-weights comments that have a high number of views, typically comments that were posted within the first hour of a submission. In this paper, author points out that this ranking task is very similar to the multi-armed bandit problem, and that there are a number of alternative approaches developed in this area that likely outperform this lower bound approach.

Discussions in Twitter

You are welcome to check out an updated version for our Twicus - discussions in Twitter mashup.

Discussion here is a flow of messages (statuses) with some hash tag. Mashup lets users add a special status for the own timeline during the first visit. It is like check-in. This check-in record contains hash tag for the discussion. So, user can switch to search right with one click right from your new post. Additionally, user's timeline will keep check-in record (read - description to hashtag), so it is easy to return back to that discussion. For subsequent visits mashup simply redirects user to Twitter search page for the given hash tag.

You can set your own parameters for the discussion. Basic URL proceeds the following parameters:

tag - tag for discussion
title - explanation for your discussion
checkin - check-in message to be published in user's timeline
via - Optional. Twitter's account to follow for the check-in message
init - Optional. 0 value lets you skip an initial screen. Default value is 1.

For example: http://twicus.linkstore.ru?tag=mytag

Such way you can add links to your site/blog: 'Discuss in Twitter'

How it could be used? For example, second screen application for social TV.

Senate as Facebook network

A great visualization for soical network: "For every member, I calculated which other senators voted the same way at least 75 percent of the time. In effect, this organizes the Senate as a mini-Facebook of 100 users, in which any given pair of senators are friends if they meet this 75-percent threshold….Visualizations like this one work by treating the senators as particles that repel one another, and treating the connections between them as springs that hold them together. Because the Democrats vote so cohesively, with few defectors, they are held together by a large number of springs."

The paper discusses the current state and development proposals for Smart Cities and Future Internet projects. Definitions of a Smart City can vary but usually tend to suggest the use of innovative Info-Communication technologies such as the Internet of Things and Web 2.0 to deliver more effective and efficient public service s that improve living and working conditions and create more sustainable urban environments. Our goal is to analyze the current proposals from the developer’s point of view, highlight the really new elements, the positions borrowed from the existing tools as well as propose some new extensions. We would like to discuss the possible extensions for the existing proposals and describe add-ons that, by our opinion, let keep the future research inline with the modern approaches in the web development domain.

Web Pair - share info between browsers

Our web pairing for mobile phones has been updated. This basic service lets you connect two smart phones so you will be able to transfer data from one to another. More precisely – it links two browsers. Actually, you cal link mobile to desktop, desktop to desktop, mobile to smart TV, etc. The key idea is that internet connection should be enough for passing data from one browser to another (from any screen to another screen). There is no need to download applications. Everything should work in the browser.

How does it work? Point two browsers (two phones, for example) to the same URL: http://pair.linkstore.ru

You can use the following QR-code:

QR code
 

You can see the following:


The picture will be the same in the second browser. Just a code should be different:


This random code will be used for pairing two devices. It is the schema similar to Bluetooth pairing. On the screen (phone) that should display the data (be linked to another phone/screen in slave mode) type the code presented on the second phone. You do not need to type anything on the second (master) phone.


Now our slave screen is ready to accept data:


As soon as the code in entered, the second screen (master) will be updated automatically:


Type any text and press Push button on the master screen. You (your pal) will see data on the slave screen:


It is a basic example that transfers text data. Technically it is possible to pass any data available in the browser. What you can transfer right now:

- just type any text. All connected slaves phones will see that

- type any phone number. It will be presented as a clickable link on the slave screen (screens)

- type any URL. E.g. http://servletsuite.com Slave screen will show a clickable link

- type any email address. Slave screen will show a clickable link

- type the following command t:some_name_from_Twitter. E.g.:  t:t411. Slave screen (screens) will show the link to that account in Twitter (http://twitter.com/t411 in our example). So, your pals will be able to read your feed, follow it, etc.

- type the following command f:some_name_from_Facebook. The same as above but for Facebook. Slave screen (screens) will show the link to that profile in Facebook. So, your pals will be able to read your feed, subscribe, etc.

- type the following command v:some_name_from_Vkontakte. The same as above but for Vkontakte. Slave screen (screens) will show the link to that profile in Vkontakte. So, your pals will be able to read your feed, subscribe, etc.

What are the prototypes? There are two componets in Coldtags suite. Both controls are pre-ajax and use frames but they work. They are Cobrowse and Slide.

Connecting devices

So, you want to build a connected sensor device? Here's what you need to know.

The purpose of this document is to provide an overview of infrastructure, options, and tradeoffs for the parts of the data ecosystem that deal with generating, storing, transmitting, and sharing data. In addition to providing an overview, the goal is to learn what the pain points are, so we can address them. - A collaborative resource

Nearest-Neighbor Searching Under Uncertainty

"Nearest-neighbor queries, which ask for returning the nearest neighbor of a query point in a set of points, are important and widely studied in many elds because of a wide range of applications. In many of these applications, such as sensor databases, location based services, face recognition, and mobile data, the location of data is imprecise. We therefore study nearest neighbor queries in a probabilistic framework in which the location of each input point and/or query point is speci ed as a probability density function and the goal is to return the point that minimizes the expected distance, which we refer to as the expected nearest neighbor (ENN)." - a couple of interesting articles. Part 1 and Part 2

Geo Forums - discussions on the map

Our mashup Geo Talk has been updated. It lets you create forums (discussions) linked to the selected place on the map. Cloud forums on the map.

Just mark a place, type a question (suggestion, information etc.) – in other words create an initiation for the discussion and get unique link for the map with embedded forum. After that you can share this link with your partners/colleges, print in your blog / twitter etc. – it depends on your own decision only – who you want to see among readers. And after that you can just follow to the discussion.

No registration required. Technically, it is Google Maps + cloud forums from Disqus.

You can discuss some geo points, POI’s (points of interests – shops, bars etc.) or, for example, create a private forum devoted so some meeting in the selected place.

Any discussion could be copied right to your mobile phone as HTML5 mobile web application via QR-codes.

Just for example – forum for Golden Apple bar in Moscow

Initially, mashup ( http://geotalk.linkstore.ru ) is trying to detect your location (as per W3C spec). If you know that forums should be created in some particular area, just set additional parameters for the above-mentioned URL:

lat - a latitude
lng – a longitude
zml – an initial zoom level
hl – a language for map

E.g. create forums in London

P.S. check out also our similar mashups: City forums and Mobile forum

DIY Data Science

"The blogging revolution in publishing is a great example of this. Once everyone could have a printing press, we got to see many important developments that did not and would not have happened as long as publishing was a high cost operation limited to professionals.

So what is the Tumblr or Blogger or Wordpress of data science?" - an interesting discussion.

So, what is it? StatWing? SilkApp? Plain Excel? Here is an excellent paper about Logistic Regression for Predicting Bad Trips. Excel based. What do you think?

Smart Cities software for developers

The paper discusses the current state and development proposals for Smart Cities and Future Internet projects. Definitions of a Smart City can vary but usually tend to suggest the use of innovative Info-Communication technologies such as the Internet of Things and Web 2.0 to deliver more effective and efficient public services that improve living and working conditions and create more sustainable urban environments. Our goal is to analyze the current proposals from the developer's point of view, highlight the really new elements, the positions borrowed from the existing tools as well as propose some new extensions. We would like to discuss the possible extensions for the existing proposals and describe add-ons that, by our opinion, let keep the future research inline with the modern approaches in the web development domain. Our new paper Smart Cities Software from the developer's point of view.

It has been submitted to 6-th Conference Applied Information and Communication Technology AICT2013

Big data - big problems

YouTube search API cannot select videos by location anymore. It is the response from support:

"Apologies for the lack of advanced warning and the loss of functionality; a change in the YouTube search index is preventing location-based searches from returning results.

Unfortunately, there is no quick-fix to account for this change. The last I heard we're looking at approximately four weeks before the necessary data to power location-based searches will return."

and later:

"Unfortunately, the teams responsible have revised their estimates for when they can get this working again, and they're longer than initially thought. I don't have an exact date to share at this point, but it will not be the mid-April timeframe we initially communicated. Apologies for the continued inconvenienced."

Summary for Summly

"Finally, the entire Summly discussion seems to be missing a critical element: there seem to be no happy users of Summly. A search for "I use Summly" reveals 6 hits, only two of which seem unique. For 1M downloads, that's a strange outcome.

But it's not unexpected. For only a robot would fall in love with a product that robotically extracts" - What's Actually Wrong with Yahoo's Purchase of Summly

Redesigned geo-fences

Many of modern location-based services are often based on an area or place as opposed to an accurate determination of the precise location. Geo-fencing approach is based on the observation that users move from one place to another and then stay at that place for a while. These places can be, for example, commercial properties, homes, office centers and so on. As per geo-fencing approach they could be described (defined) as some geographic areas bounded by polygons. It assumes users simply move from fence to fence and stay inside fences for a while. In this article we replace geo-based boundaries with network proximity rules. This new approach let us effectively deploy location based services indoor and provide a significant energy saving for mobile devices comparing with the traditional methods. It is our new paper Geofence and Network Proximity

Wireless Networks Sensors and Social Streams

Can use sensors for redefining check-ins? The paper introduces a new approach for using wireless sensors on mobile phones for integrating data from social networks. We describe existing models for integrating sensors and social networks, as well as propose a new practical approach for social context-aware data discovery that uses mobile phone as proximity sensor. Our concept uses wireless networks sensors from mobile phones (Wi-Fi, Bluetooth) as presence sensor that can open (discover) access for some content published in the social networks. Our presentation from AINA-2013 conference.

About indoor positioning

Apple has acquired indoor-GPS company WifiSLAM, a sign that the war over indoor mobile location services is heating up

The two-year-old startup has developed ways for mobile apps to detect a phone user’s location in a building using Wi-Fi signals. It is interesting, because Wi-Fi processing on non-rooted iPhone is very limited. Does it mean, that Apple changes its position in this space? We are very interested in porting SpotEx approach to iPhone.

Proximity and trajectories

This paper describes an algorithm for discovery of convoys in database with proximity log. Traditionally, discovery of convoys covers trajectories databases. This paper presents a model for context-aware browsing application based on the network proximity. Our model uses mobile phone as proximity sensor and proximity data replaces location information. As per our concept, any existing or even especially created wireless network node could be used as presence sensor that can discover access to some dynamic or user-generated content. Content revelation in this model depends on rules based on the proximity. Discovery of convoys in historical user's logs provides a new class of rules for delivering local content to mobile subscribers. It is our new paper Discovery of Convoys in Network Proximity Log
