Title: Localization of Wireless Devices in Covered Areas using Compressive Sensing

Abstract: New smartphones are equipped with plurality of sensors. Accelerometer, gyro, barometer, and magnetometer are among the sensors commonly available in new generation of smartphones. Using recent advances in signal processing such as Compressive Sensing, we have developed precise positioning schemes that can find user’s location in covered areas where the GPS service is not available. Our technology uses RF signals received from WiFi access points or iBeacons, along with the readings from multiple sensors, to locate the user. We have developed solutions for integration of multiple sensor readings into a single cohesive database. Our solutions are device-agnostic, which makes them excellent candidates for crowdsourcing. There are various applications for location estimation such as monitoring children and elderly, customer service in shopping malls, tracking goods and assets, targeted marketing, and localization of personnel in factories and mines. In this talk, we will present some of our approaches and will demo our solution.

Title: Advance methodology for examination of stock market news

-A Sentiment Analysis –

Abstract: The imitation of the mental ability of word association is the objective of the hybrid text mining conception, called CIMAWA. The algorithm of the concept measures the symmetric and asymmetric strength of association between two words in a corpus of documents. The calculation is based on co-occurrences and frequencies of words and the outcome of the formula is a numeric value. As an innovative method for sentiment analysis we combined CIMAWA with a dictionary-based approach for keyword detection and evaluation with the help of a lexical resource. With positive, neutral or negative polarity of words it is possible to value each strength of word association. For application, we developed a software prototype and used this method on a large collection of financial market news from January 2000 through February 2014 and compared the calculated sentiment values of companies with the development of their stock price over the time.
