Does my city have a nice, quiet beer garden with a grill? Which restaurant has spicy Asian cuisine on its menu, and which cafe dreamily delicious cakes? Who offers the quickest service for a tasty lunch?
Nowadays, anyone turning to the Internet in search of the special features of the local restaurant scene can choose between a host of online reviews or starred listings in portals for general categories such as value for the money, food and service. What is often lacking, though, is the reasoning behind the good or bad review.
A new, intelligent smartphone app now provides details about restaurants, bars and cafes: “Eat and Drink“ analyzes more than 200,000 reviews from throughout the Internet, condensing opinions, bundling information, gleaning specific features from the sources and providing restaurant recommendations. At a glance, the user can see whether or not the atmosphere is welcoming, the clientele is young, or the background music is a source of annoyance.
“Our intelligent app makes the user‘s job easier. There‘s no need to read through lengthy restaurant reviews, instead the app provides a summary of the special features and main aspects of a particular establishment. ‘Eat and Drink‘ provides information as to why a particular rating is positive or negative,“ Dr. Melanie Knapp of the Fraunhofer Institute Intelligent Analysis and Information Systems IAIS notes. “The user simply launches an area or keyword search. The result is displayed in the form of tags.“
With “Eat and Drink,“ Knapp and her team have created an app that semantically analyzes and processes unstructured text. In contrast to keyword or rule-based processes like those used by well-known online search engines, this solution uses learning and pattern-recognizing methods to deliver results that are much more refined and far less cut-out in nature. The researchers call their intelligent search methods “Smart Semantics“. This approach enables machine-driven classification of complex websites and detailed analysis of text, even at the sentence level. The method studies syntax, individual words, verbs, pronouns and nouns. The underlying technologies on which the app is based were developed by IAIS scientists in the THESEUS research program (www.theseus-programm.de/en/index.php). “Customer opinions can be optimally evaluated using our search technology. It can be flexibly adapted for use with all kinds of topics and text. Apps and programs could also be developed for entirely different sectors, such as consumer goods or the automobile industry. ‚Eat and Drink‘ is just one example of how technologies generated under the THESEUS program can be practically applied in the B2C and B2B areas,“ Knapp explains.
Just what such a B2B application might look like is demonstrated by the experts in the form of “Quote“ – a semantic search engine for quotations. This application has been trained to hunt down quotations by public figures found in online premium news providers. Angela Merkel, Magdalena Neuner or Till Schweiger are just some of the VIPs whose statements can be called up using the app. Users can also search for quotes on specific topics, such as Greece or the euro – “Quote“ returns current quotations found on the content of interest. The app also generates a fact file on each person. The file provides a list of the topics on which the person in question has been quoted in recent months. “Press offices are not the only ones interested in ‘Quote‘. Politicians and managers in the public eye can also use the search engine as a research tool, or to analyze the competition,“ Knapp is convinced. Researchers will be demonstrating their Smart Semantic Apps in action from March 6 through 10 at the CeBIT trade fair, at the joint Fraunhofer stand located in Hall 9, Stand E08.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
